Subject: [PATCH 0002/1971] ACPI: rename some functions

We want the name 'to_acpi_device'.
And the current macro 'to_acpi_device' will be removed
after device model is setup.
So just simply rename them.

Subject: [PATCH 0004/1971] ACPI: add ACPI bus_type for driver model

Add ACPI bus_type for Linux driver model.

1.	.shutdown method is added into acpi_driver.ops
	needed by bus_type operations.
2.	remove useless parameter 'int state' in .resume method.
3.	change parameter 'int state'
	to 'pm_message_t state' in .suspend method.

Note:	The new .uevent method mark ACPI drivers by PNPID instead of by name.
	Udev script needs to look for "HWID=" or "COMPTID=" to load
	ACPI drivers as a result.

Subject: [PATCH 0007/1971] ACPI: convert to sysfs framework

Setup new sysfs framework

1.	Remove /sys/firmware/acpi
2.	Add ACPI device in device tree.

File "eject" for every device that has _EJ0 method is moved from
/sys/firmware to /sys/devices.
Operation on this file is exactly the same as before.
i.e. echo 1 to "eject" will cause hot removal of this device.
Corresponding changes should be made in userspace for hot removal.

Subject: [PATCH 0008/1971] ACPI: add acpi_bus_ops in acpi_device

Add acpi_bus_ops in acpi_device to support acpi hot plug.

NOTE:	Two methods .add and .start in acpi_driver.ops are
	called separately to probe ACPI devices, while only
	.probe method is called in driver model.
	As executing .add and .start separately is critical
	for ACPI device hot plug, we use acpi_bus_ops to
	distinguish different code path.

Subject: [PATCH 0009/1971] ACPI: add acpi_bus_removal_type in acpi_device

Add removal_type in structure acpi_device for hot removal.

ACPI_BUS_REMOVAL_EJECT is used for ACPI device hot removal.
Only one parameter is allowed in .remove method due to driver model.
So removal_type is added to indicate different removal type.

Subject: [PATCH 0011/1971] ACPI: Convert ACPI PCI .bind/.unbind to use PCI
 bridge driver

acpi_device had a .bind/.unbind methods, but Linux driver model does not.
Cut ACPI PCI code over to use the Linux driver model methods.

Convert bind/unbind to use a new pci bridge driver.
The driver will add/remove _PRT, so we can eventually
remove .bind/.unbind methods.

Subject: [PATCH 0012/1971] ACPI: Set fake hid for non-PNPID ACPI devices

We do this mainly because:
1.	hid is used to match ACPI devices and drivers.
	.match method which is incompatible to driver model
	can be deleted from acpi_driver.ops then.
2.	As the .uevent method mark ACPI drivers by PNPID,
	fake hid is set to non-PNPID devices so that udev script
	can load the right ACPI driver by looking for
	"HWID = " or "COMPTID = ".

+The output sysfs class driver provides an abstract video output layer that
+can be used to hook platform specific methods to enable/disable video output
+device through common sysfs interface. For example, on my IBM ThinkPad T42
+laptop, The ACPI video driver registered its output devices and read/write
+method for 'state' with output sysfs class. The user interface under sysfs is:
+
+linux:/sys/class/video_output # tree .

Subject: [PATCH 0017/1971] ACPI: use PNPID:instance_no as bus_id of ACPI
 device

Previously we used the device name in the DSDT, but would
crash upon encountering a duplicate. Also, exposing the
DSDT device name to the user in a patch isn't a good idea,
because it is arbitrary.

After some discussion, we finally decided to use
"PNPID:instance_no" as the bus_id of ACPI devices.

Two attributes for each device are added at the same time,
the full pathname in ACPI namespace and hardware_id if it has.

NOTE:	acpi_bus_id_list is used to keep the information of PNPID
	and instance number of the given PNPID. Loop the
	acpi_bus_id_list to find the instance_no of the	same PNPID
	when register a device. If failed, i.e. we don't have a
	node with this PNPID, allocate one and link it to this list.

NOTE:	Now I don't take the memory free work in charge.
	If necessary, I can add a reference count in
	struct acpi_device_bus_id, and check the reference and
	when unregister a device, i.e. memory is freed when
	the reference count of a given PNPID is 0.

Subject: [PATCH 0018/1971] ACPI: fix Supermicro X7DB8+ Boot regression

http://bugzilla.kernel.org/show_bug.cgi?id=7695

Originally we converted bind/unbind to use a new pci bridge driver.
The driver will add/remove _PRT, so we can eventually remove
.bind/.unbind methods.

But we found that some of the _ADR-Based devices don't have _PRT,
i.e. they are not managed by the new ACPI PCI bridge driver.
So that .bind method is not called for some _ADR-Based devices,
which leads to a failure.

Now we make ACPI PCI Root Bridge Driver scan and binds all _ADR-Based devices
once the driver is loaded, in the .add method of ACPI PCI Root Bridge driver.

Extra code path for calling .bind/.unbind when _ADR-Based devices
are hot added/removed is also added.

Subject: [PATCH 0020/1971] ACPI: use more understandable bus_id for ACPI
 devices

Some of the ACPI devices use the internal fake hids
which are exposed to userspace as devces' bus_id after sysfs conversion.
To make it more friendly, we convert them to more understandable strings.

For those devices w/o PNPids, we use "device:instance_no" as the bus_id
instead of "PNPIDNON:instance_no".

JFS should mark the superblock dirty and return an error rather than
calling BUG().

Subject: [PATCH 0023/1971] [SCSI] 53c700: Allow setting burst length

This is a patch, which allows not only disabling bursting but to specify
different burst lenghts. This feature is needed to get the 53c700 driver
working for the onboard SCSI controller of SNI RM machines, which only
work reliably with a 4 word burst length.

Subject: [PATCH 0026/1971] [SCSI] kill scsi_rety_command

scsi_retry_command only has a single caller, so there is no point
in having this function.  Additionally the memset of the sense
buffer it does is entirely superflous as scsi_request_fn already
calls scsi_init_cmd_errh to perform this memset before the command
is reissued.

Subject: [PATCH 0027/1971] [SCSI] mptctl for mptsas

This patch makes the mptctl pass through available if
the mptsas driver is selected. Without this patch
if mptsas is the only fusion driver chosen, then
the mptctl is not presented as an option.

smp_utils uses the mptctl driver to pass SAS SMP
functions through a MPT SAS HBA.

Subject: [PATCH 0028/1971] [SCSI] scsi_debug: error processing

After discussions in the thread titled:
    [PATCH] scsi_debug: illegal blocking memory allocation
here is a patch containing the discussed fix and some other
fixes and additions. The patch is against lk 2.6.20-rc3 .
The version is bumped to 1.81 .

ChangeLog:
  - Change several GFP_KERNEL allocations to GFP_ATOMIC
    as they can be called from queuecommand() context
  - check above allocation returns and if out of memory
    report DID_REQUEUE in two cases, DID_NO_CONNECT in
    another, and fail slave configure() in another
  - add support for WRITE BUFFER command
  - add aborted_command error injection support
    (opts mask 0x10), similar mechanism to
    recovered_error injection.

Subject: [PATCH 0029/1971] [SCSI] megaraid_{mm,mbox}: init fix for kdump

1.      Changes in Initialization to fix kdump failure.
        Send SYNC command on loading.
        This command clears the pending commands in the adapter
        and re-initialize its internal RAID structure.
        Without this change, megaraid driver either panics or fails to
        initialize the adapter during kdump's second kernel boot
        if there are pending commands or interrupts from other devices
        sharing the same IRQ.
2.      Authors email-id domain name changed from lsil.com to lsi.com.
        Also modified the MODULE_AUTHOR to megaraidlinux@lsi.com

From a69b74d39f50b3e3ca9a6641bd71f3fc55d32d98 Mon Sep 17 00:00:00 2001
From: Randy Dunlap <randy.dunlap@oracle.com>
Date: Fri, 5 Jan 2007 22:41:48 -0800
Subject: [PATCH 0030/1971] [SCSI] megaraid: fix kernel-doc

kernel-doc modifications:
- change "@param var" notation to @var;
- change function/description separator from ':' to '-';
- change var/description separator from '-' to ':';
- fix a few doc. typos;
- don't use kernel-doc /** lead-in when the doc. block is not kernel-doc;
- use Linux common */ ending comment format instead of **/;
- use correct function parameter names;
- place function parameters immediately after the function short description;
- place kernel-doc immediately before its function or macro;

Subject: [PATCH 0032/1971] [SCSI] scsi_scan message cosmetic error

Hi,

Minor typo ...
In my first iteration of patches (that got merged), the
BLIST_ATTACH_PQ3 actually had the value 0x800000, but that
got changed later to avoid conflicts. This piece must have
been overlooked.
You could obviously do something like %x and then add the
bitflags, but that looks overkill for something that does
not tend to change.

Please merge.
(Patch applied against latest 2.6.20rc version that I tested.)

 starget_for_each_device()

Removed spin_unlock_irq()/spin_lock_irq() pairs surrounding
starget_for_each_device() calls.
As Matthew W. pointed out, starget_for_each_device() can be called under
a spinlock being held.
The change has been tested and verified on qla2xxx.ko module.
Thanks Matthew W. and Hisashi H. for help.

Subject: [PATCH 0034/1971] [SCSI] libsas: Clean up rphys/port dev list after a
 discovery error.

sas_get_port_device assigns a rphy to a domain device in anticipation
of finding a disk.  When a discovery error occurs in
sas_discover_{sata,sas,expander}*, however, we need to clean up that
rphy and the port device list so that we don't GPF.  In addition, we
need to check the result of the second sas_notify_lldd_dev_found.
This patch seems ok on a x260, x366 and x206m.

Subject: [PATCH 0036/1971] [SCSI] libsas: Don't give scsi_cmnds to the EH if
 they never made it to the SAS LLDD or have already returned

On a system with many SAS targets, it appears possible that a scsi_cmnd
can time out without ever making it to the SAS LLDD or at the same time
that a completion is occurring.  In both of these cases, telling the
LLDD to abort the sas_task makes no sense because the LLDD won't know
about the sas_task; what we really want to do is to increase the timer.
Note that this involves creating another sas_task bit to indicate
whether or not the task has been sent to the LLDD; I could have
implemented this by slightly redefining SAS_TASK_STATE_PENDING, but
this way seems cleaner.

This second version amends the aic94xx portion to set the
TASK_AT_INITIATOR flag for all sas_tasks that were passed to
lldd_execute_task.

Subject: [PATCH 0037/1971] [SCSI] libsas: Add a sysfs knob to enable/disable a
 phy

This patch lets a user arbitrarily enable or disable a phy via sysfs.
Potential applications include shutting down a phy to replace one
lane of wide port, and (more importantly) providing a method for the
libata SATL to control the phy.

Subject: [PATCH 0038/1971] [SCSI] libsas: Reset timer on taskless scsi_cmnds
 in sas_scsi_timed_out

Every so often, a scsi_cmnd will time out, and the libsas timeout handler
will discover that the scsi_cmnd does not have a sas_task attached to it.
This can happen in two cases: (1) the scsi_cmnd actually made it through
libsas to the HBA and is now going through scsi_done, or (2) the
scsi_cmnd has been held up (host lock, slab alloc, etc) and libsas has
not yet attached a sas_task.  In both cases, it is safe to ask SCSI for
more time to process the command via EH_RESET_TIMER; we cannot blindly
return EH_HANDLED because if (2) happens, we could end up calling
scsi_done while another CPU is heading towards sas_queuecommand, which
causes slab corruption when sas_task_done updates the freed scsi_cmnd.

we should set it or remove the parameter.  This allows us to enable task

Subject: [PATCH 0042/1971] [SCSI] aic94xx: Don't eat TMF_QUERY_TASK results

In this driver, TMF_QUERY_TASK translates to QUERY_SSP_TASK.  The
sequencer, it seems, is perfectly happy sending us a SSP response, which
this function promptly "converts" into TMF_RESP_FUNC_FAILED.  This leads to
the SAS EH making bad decisions based on bad data, so we should not perform
the conversion in this case.

Subject: [PATCH 0043/1971] [SCSI] libsas: Remove SAS_TASK_INITIATOR_ABORTED
 flag

This flag is no longer necessary because we push tasks to be aborted into
the EH as soon as we possibly can, and let the SCSI EH code take care of
the coordination for which this flag was used.

Subject: [PATCH 0044/1971] [SCSI] libsas: Enable the EH strategy handler to
 reset a phy after a command

When a SAS LLDD needs to request a device port reset, it needs to have all
commands aborted before it can reset the port.  Since commands are put on
the EH's list in the order that they were queued, the LLDD can set a "need
reset" flag in the last task to be aborted so that the EH can reset the
port after all commands are aborted.

Subject: [PATCH 0045/1971] [SCSI] libsas: Delay issuing ABORT TASK TMF until
 the error handler

sas_task_abort() should simply abort the upper-level SCSI command and wait
until the error handler to send the actual ABORT TASK command.  By
deferring things to the EH we simplify the concurrency coordination and
eliminate some race conditions.  Note that sas_task_abort has a few hooks
to handle libsas internal commands properly too.

Also rename do_sas_task_abort to __sas_task_abort just in case we really
want to abort the task *right now* and we don't have a scsi_cmnd attached
to the command.  This is a hook for libata internal commands to abort.

 REQ_TASK_ABORT/REQ_DEVICE_RESET code

Now that task aborts and device port resets are done by the EH, we can
remove all the code that set up workqueues and such and simply call
sas_task_abort and let libsas figure things out.

 release_firmware

The vmalloc() blob holding the sequencer firmware wasn't being released at
module unload time, which resulted in a memory leak.

Ed Chim of Adaptec informs us that the DDB registers need to be zeroed at
initialization time and that some SCB initializations need to happen even if
we don't use the SCB.

Subject: [PATCH 0049/1971] [SCSI] aic94xx: Lock DDB read/write accesses

Extend the use of the DDB lock to include all DDB accesses, because
DDB updates now occur from multiple threads.  This fixes the SMP timeout
problems that we were occasionally seeing with a x260, because the
controller got confused when the DDBs got corrupted.

Subject: [PATCH 0050/1971] [SCSI] libsas: sysfs phy control attributes should
 not be S_IWUGO

Allowing the phy reset controls to be world-triggerable does not seem like
a terribly good idea because SAS devices can be disrupted (and ATA devices
are really disrupted) by a phy reset.  By default only root should be able
to do things like that.

Subject: [PATCH 0055/1971] ACPI: Optimize acpi_get_pci_rootbridge_handle() to
 boot faster

Move acpi_get_pci_rootbridge_handle() from glue.c to pci_root.c and get the
root bridge ACPI handles by searching the &acpi_pci_roots list instead of
walking through the ACPI name space.  This significantly reduces boot time
on large I/O systems.

Subject: [PATCH 0056/1971] JFS: call io_schedule() instead of schedule() to
 avoid deadlock

The introduction of Jens Axboe's explicit i/o plugging patches introduced a
deadlock in jfs.  This was caused by the process initiating I/O not
unplugging the queue before waiting on the commit thread.  The commit
thread itself was waiting for that I/O to complete.  Calling io_schedule()
rather than schedule() unplugs the I/O queue avoiding the deadlock, and it
appears to be the right function to call in any case.

Subject: [PATCH 0059/1971] Input: gpio-keys - keyboard driver for GPIO buttons

This is an interrupt-driven keyboard driver for simple buttons
connected directly to CPU GPIO lines of embedded ARM systems.
It supports pxa architectures and is used by a number of PDAs
and PocketPC phones in the handhelds.org kernel. Support for
other architectures, such as sa11xx and sc2410, will be added
once generic GPIO API is available.

Subject: [PATCH 0060/1971] Input: ads7846 - pluggable filtering logic

Some LCDs like the LS041Y3 require a customized filtering
logic for reliable readings, so make the filtering function
replacable through platform specific hooks.

Subject: [PATCH 0062/1971] Input: ads7846 - switch to using hrtimer

Use hrtimer instead of the normal timer, since it provides better
sampling resolution. This will:

 - avoid a problem where we have a 1 jiffy poll period and
   dynamic tick on
 - utilize high resolution HW clocks when they are added to
   the hrtimer framework

We can't depend on the pressure value to determine when the pen was
lifted, so use the GPIO line state instead. This also helps with
chips (like ads7843) that don't have pressure sensors.

Subject: [PATCH 0068/1971] [POWERPC] Move ELF_ET_DYN_BASE up to 512MB point

I often test new versions of glibc by doing:

LD_LIBRARY_PATH=/XXX/lib /XXX/lib/ld.so.1 <binary>

One test case ended up SEGV'ing. Upon closer inspection ld.so was loaded
at 0x8000000 (128MB) with the heap right after it. Since we normally
link binaries at 0x10000000 (256MB) we only had about 128MB of space for
the heap:

00100000-00103000 r-xp 00100000 00:00 0           [vdso]
08000000-0801e000 r-xp 00000000 00:01 33079       /lib/ld-2.5.so
0802d000-0802f000 rwxp 0001d000 00:01 33079       /lib/ld-2.5.so
0802f000-08050000 rwxp 0802f000 00:00 0           [heap]
0fe91000-0ffd9000 r-xp 00000000 00:01 33082       /lib/libc-2.5.so
0ffd9000-0ffe8000 ---p 00148000 00:01 33082       /lib/libc-2.5.so
0ffe8000-0ffea000 r--p 00147000 00:01 33082       /lib/libc-2.5.so
0ffea000-0ffed000 rwxp 00149000 00:01 33082       /lib/libc-2.5.so
10000000-10004000 r-xp 00000000 00:01 76          /bin/sleep
10013000-10014000 rwxp 00003000 00:01 76          /bin/sleep
ffb41000-ffb56000 rw-p ffb41000 00:00 0           [stack]

One way to fix this is move ELF_ET_DYN_BASE from 0x08000000 to 0x20000000.
This allows 128MB for the binary (hopefully enough for even the most
crazy c++ apps), and with our current layout we will grow the heap up
and the stack down, allowing potentially gigabytes of heap:

Subject: [PATCH 0069/1971] [POWERPC] Do not write virq back to PCI config
 space

- Drivers will not rely on the PCI config space value, as they've
  already been conditioned to rely on the irq field in "struct pci_dev".

- The virq value may not be < 256 as it has been remapped.

- The PCI config space should reflect the hardware configuration, which
  is not being changed.  We are only creating a virtual irq mapping that
  exists in the kernel only. One would never expect the PCI hardware to
  generate the "virq" interrupt.

Subject: [PATCH 0091/1971] [POWERPC] 83xx: Fix Kconfig to only enable FP math
 emulation for the MPC832x

Updated MATH_EMULATION depends to be on PPC_MPC832x instead of PPC_83xx.  Only
the the MPC832x has no floating point unit in the core.  Updated the other
83xx defconfigs that got math emulation turned on incorrectly.

Subject: [PATCH 0092/1971] [POWERPC] 83xx: Don't call ioremap in the reset
 function

It's possibly that we get an reset requestion when interrupts are disabled.
(For example an oops in an interrupt handler).  Therefor, we can't call
ioremap in the reset function.  Moving the ioremap of the registers we
need access to an arch_initcall helps the problem.

However we still have a window between boot and the arch_initcall in
which the register pointer will not be setup and thus we spin if the reset
function is called.  If one needs to ensure even this case is covered, look
at use of the watchdog provided on 83xx to reset the processor.

Subject: [PATCH 0094/1971] ACPI: move FADT resource reservations from
 motherboard driver to osl

Resources described by the FADT aren't really a good fit for the
ACPI motherboard driver.

The motherboard driver cares about PNP0C01 and PNP0C02 devices and
their resources.

The FADT describes some resources used by the ACPI core.  Often, they
are also described by by the _CRS of a motherboard device, but I think
it's better to reserve them specifically in the ACPI osl.c because
(a) the motherboard driver is optional and ACPI uses the resources even
if the driver is absent, and (b) I want to remove the ACPI motherboard
driver because it's mostly redundant with the PNP system.c driver.

Subject: [PATCH 0097/1971] i386: turn on CONFIG_PNP in defconfig

I'm trying to remove drivers/acpi/motherboard.c, which is mostly
redundant with drivers/pnp/system.c.  So make sure that we include the
PNP driver in the default config.  Most distros enable this already.

Turning on CONFIG_PNP also causes the following options to be enabled:

    CONFIG_PNPACPI
    CONFIG_SERIAL_8250_PNP

CONFIG_SERIAL_8250_PNP causes legacy serial ports to be discovered
twice, which is ugly but harmless:

    serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
    00:07: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

Subject: [PATCH 0098/1971] ACPI: remove motherboard driver (redundant with PNP
 system driver)

The PNP system board driver (drivers/pnp/system.c) contains all the
same functionality, so we don't need the ACPI version.

Previously, a motherboard device would be claimed by *both* the ACPI and
PNP drivers, resulting in stuff like this in /proc/ioports:

    1200-121f : motherboard	<-- from drivers/acpi/motherboard.c
      1200-121f : pnp 00:0d	<-- from drivers/pnp/system.c

Make sure to enable CONFIG_PNP (and CONFIG_PNPACPI) to include the
PNP system board driver.

Subject: [PATCH 0100/1971] [POWERPC] 83xx: Return a point to the struct ipic
 from ipic_init()

It's useful to have access to struct ipic handle that just got created
in ipic_init().

For example, if we want to setup an external IRQ with out
a device node we need access ipic->irqhost to create the virtual to HW
IRQ mapping and to set the IRQ sense.  With this we can mimic the old
sense array concept that existed in arch/ppc.

jfs_debug.h uses an incorrect CONFIG_KERNEL_ASSERT ifdef to redefine the
assert macro for kgdb use.  I believe the code worked a long time ago, but
today it's not a valid config option.  Since I'm not aware of anybody
interested in debugging jfs with kgdb, it should just be removed.

Thanks to Robert P. J. Day for reporting this.

Subject: [PATCH 0105/1971] [SCSI] ipr: Remove usage of pci driver data

Since ipr handles dynamic ids, it must handle driver_data
not being set, so remove the current usage of driver_data
so it can be used for other things in future patches.

Subject: [PATCH 0107/1971] [SCSI] ipr: PCI error recovery fix

Since the pci_block_user_cfg_access API was modified to track
block/unblocks, it was discovered that the ipr driver had a
path through its code (in PCI error recovery) which would unblock
when not previously blocked.

Subject: [PATCH 0109/1971] [SCSI] aacraid: rework communication support code

Received from Mark Salyzyn,

Replace all if/else communication transports with a platform function call.
This is in recognition of the need to migrate to up-and-coming transports.
Currently the Linux driver does not support two available communication
transports provided by our products, these will be added in future patches, and
will expand the platform function set.

From e8f32de52c0d74d397d21afc655a4e2a7dfe1f98 Mon Sep 17 00:00:00 2001
From: Mark Haverkamp <markh@linux-foundation.org>
Date: Tue, 23 Jan 2007 15:00:30 -0800
Subject: [PATCH 0111/1971] [SCSI] aacraid: rework packet support code

Received from Mark Salyzyn,

Replace all if/else packet formations with platform function calls. This is in
recognition of the proliferation of read and write packet types, and in the
need to migrate to up-and-coming packets for new products.

Subject: [PATCH 0112/1971] [SCSI] aacraid: expanded expose physical device
 code (new)

Received from Mark Salyzyn,

Take the expose_physicals flag and allow the user to select default (physicals
available via /dev/sg), exposed (physicals available via /dev/sd for
experimental reasons) and hidden (physicals blocked from all access). This
expands the functionality of the previous expose_physicals insmod parameter
which was added to support some experimental configurations.

Subject: [PATCH 0114/1971] [SCSI] libsas: Fix incorrect sas_port deformation
 in sas_form_port

Currently, sas_form_port checks the given asd_sas_phy's sas_phy to see if
there's already a port attached.  If so, the SAS addresses of the port and
the phy are compared to determine if we need to detach from the port
because the addresses don't match or if we can stop; the SAS address stored
in the sas_port reflects whatever device _was_ attached to the port/phy, and
the SAS address stored in the sas_port reflects whatever device we just
discovered.  As written, the code detaches from the port if the addresses
_do_ match, and prints an error if they do _not_ match.  I believe this to
be incorrect, as it seems more logical to keep the port if the addresses
match (i.e. the phy was reset but the device didn't change), and detach it
they do not (i.e. the device changed).

layer and frees the sas_rphy.  This can be broken down into two functions,
sas_rphy_remove and sas_rphy_free; sas_rphy_remove is of interest to
sas_discover_root_expander because it calls functions that require
sas_rphy_add as a prerequisite and can fail (namely sas_discover_expander).
In that case, sas_discover_root_expander needs to be able to undo the effects
of sas_rphy_add yet leave the job of freeing the sas_rphy to the caller of
sas_discover_root_expander.

This patch also removes some unnecessary code from sas_discover_end_dev
to eliminate an unnecessary cycle of sas_notify_lldd_gone/found for SAS
devices, thus eliminating a sas_rphy_remove call (and fixing a race condition
where a SCSI target scan can come in between the gone and found call).
It also moves the sas_rphy_free calls into sas_discover_domain and
sas_ex_discover_end_dev to complement the sas_rphy_allocation via
sas_get_port_device.

This patch does not change the semantics of sas_rphy_delete.

Subject: [PATCH 0118/1971] [SCSI] libsas: Handle SCSI commands that complete
 with failure codes

This patch moves the code that handles SAS failures out of the main EH
function and into a separate function.  It also detects commands that have
no sas_task (i.e. they completed, but with error data) and sends them into
scsi_error for processing.  This allows us to handle SCSI errors (and
enables auto-spinup as a side effect) instead of dropping them on the
floor and falling into an infinite loop.  It also requires the
implementation of a device reset function, which the SAS failure code has
been modified to employ for REQ_DEVICE_RESET.

Subject: [PATCH 0121/1971] ACPI: add a Kconfig option for ACPI procfs
 interface

Add a kconfig option CONFIG_ACPI_PROCFS to make procfs interface
a configurable attribute of ACPI.

No procfs interface is actually deprecated,
and no sysfs interface is added in this patch.

CONGI_ACPI_PROCFS is used to mark procfs interface as deprecated
once the same function is duplicated in sysfs.

Subject: [PATCH 0122/1971] ACPI: add ACPI debug attribute in sysfs

Add ACPI debug attributes in sysfs.
/proc/acpi/debug_layer && debug_level are deprecated by
/sys/module/acpi/parameters/debug_layer && debug_level.

NOTE: The operations to them are quite the same.
E.g. if you want to enable ACPI_DB_INFO, ACPI_DB_WARN,
 ACPI_DB_ERROR and disable the others,
#echo 0x13 >/sys/module/acpi/parameters/debug_level is OK,
and a boot option "acpi.debug_level = 0x13" also works.

Adds the new driver and make ASUS_LAPTOP and ACPI_ASUS
incompatible.  It may be strange to use ASUS_CREATE_DEVICE_ATTR
and ASUS_SET_DEVICE_ATTR now, but these macro will be very
usefull in next patchs.  ASUS_HANDLE and ASUS_HANDLE_INIT comes
from IBM_HANDLE and IBM_HANDLE_INIT, with some modification,
and will also be used in next patchs.

Subject: [PATCH 0126/1971] asus-laptop: add led support

Add led support, using generic led class.  Thomas Tuttle's patch
<http://lkml.org/lkml/2006/7/6/247> was very usefull.  We use
hotk->status to store led status because it's very hard to find
acpi method to get the right status...  To reduce the code,
I use a lot of macro (ASUS_LED, ASUS_LED_REGISTER, etc ...),
because the code is the same for all leds ...

Subject: [PATCH 0127/1971] asus-laptop: add bluetooth and wlan support

WLED and BLED are not handled like other leds (MLED, etc ..),
because sometime they also control the wlan/bluetooth device.
If the method for wireless_status is found, it's used to get the
status, otherwise hotk->status is used.  We also use the HWRS
method, which tell if the bluetooth/wlan device is present or not.
This patch show why we need a ASUS_SET_DEVICE_ATTR macro : if
there is a bluetooth device, /sys/dev.../asus-laptop/bluetooth
is usable, else it's not but it's clean.

Subject: [PATCH 0128/1971] asus-laptop: add backlight support

Adds backlight support using backlight class. We now
change the brightness *and toggle the backlight !* via
/sys/class/backlight/asus-laptop/.

If the user switchs the backlight using the keyboard,
asus_hotk_notify looks for ATKD_LCD_OFF and ATKD_LCD_ON events,
and stores the right state into hotk->status and bd->props->power .

Subject: [PATCH 0136/1971] [SCSI] ipr: remove duplicate device id

This patch removes a duplicate device id from the IPR driver.  Based on
the ipr.h file, I'm not so sure this was intended to be a duplicate, and
if so, the .h file should be modified to use the proper sub-device id
instead.

This was pointed out to me by Kay Sievers <kay.sievers@suse.de>

Subject: [PATCH 0138/1971] [POWERPC] 83xx: Add the mpc832xemds defconfig

The defconfig for the 8323EMDS is identical to the 8360E MDS defconfig,
except CONFIG_MATH_EMULATION is set, since the 8323 doesn't have a FPU.

Subject: [PATCH 0142/1971] [SCSI] qla2xxx: Handle IRQ-0 assignments by the
 system.

No restriction should be placed on the IRQ number assigned
to a given ISP.  Original code incorrectly assumed a
non-zero IRQ number assignment by the system.  In these
circumstances the proper freeing of the IRQ (via free_irq())
would not take place.

Subject: [PATCH 0144/1971] [SCSI] qla2xxx: Perform implicit LOGO during fabric
 logout request.

Similarly to previous LOGO requests on non-24xx hardware,
perform an implicit-LOGO as to avoid the potential 2 *
R_A_TOV delay which can result during an explicit-LOGO
request.

Subject: [PATCH 0145/1971] [SCSI] qla2xxx: Set correct cabling state during
 initialization.

Previous work to add asynchronous-scsi-scanning support
(d19044c32baadeb80e135027124a9e845c6f057c) caused peculiar
semantic changes when no cabling was attached to the HBA
whereby unneeded and intrusive 'error-handling' would take
place due to the initial link state being unset.

Subject: [PATCH 0157/1971] ocfs2: ocfs2_link() journal credits update

Commit 592282cf2eaa33409c6511ddd3f3ecaa57daeaaa fixed some missing directory
c/mtime updates in part by introducing a dinode update in ocfs2_add_entry().
Unfortunately, ocfs2_link() (which didn't update the directory inode before)
is now missing a single journal credit. Fix this by doubling the number of
inode updates expected during hard link creation.

Subject: [PATCH 0162/1971] ACPICA: Handle mis-matched package length

Implement support within the AML interpreter for
package objects that contain a mismatch between the AML
length and package element count. In this case, the lesser
of the two is used. Some BIOS code apparently modifies
the package length on the fly, and this change supports
this. Provides compatibility with the MS AML interpreter.

Subject: [PATCH 0164/1971] ACPICA: Delete recursive feature of ACPI Global
 Lock

Completed a new design and implementation for
the ACPI Global Lock support. On the OS side, the global
lock is now treated as a standard AML mutex. Previously,
multiple OS threads could acquire the global lock
simultaneously, but this could cause the BIOS to be starved
by the lock in cases such as the Embedded Controller driver,
where there is a tight coupling between the OS and the BIOS.

+ * lock, especially in the case where there is a tight handshake between the

+ * allows only one thread to acquire the HW Global Lock at a time, and makes
+ * the global lock appear as a standard mutex on the OS side.

The ACPI Global Lock interrupt handler no longer
queues the execution of a separate thread to signal the
global lock semaphore. Instead, the semaphore is signaled
directly from the interrupt handler.

Subject: [PATCH 0171/1971] ACPICA: Implement simplified Table Manager

The Table Manager component has been completely
redesigned and reimplemented. The new design is much
simpler, and reduces the overall code and data size of
the kernel-resident ACPICA by approximately 5%. Also,
it is now possible to obtain the ACPI tables very early
during kernel initialization, even before dynamic memory
management is initialized.

- * FUNCTION:    acpi_tb_find_rsdp
- *
- * PARAMETERS:  table_info              - Where the table info is returned
- *              Flags                   - Current memory mode (logical vs.

- * RETURN:      Status, RSDP physical address
- *
- * DESCRIPTION: Search lower 1_mbyte of memory for the root system descriptor
- *              pointer structure.  If it is found, set *RSDP to point to it.
- *
- *              NOTE1: The RSDP must be either in the first 1_k of the Extended
- *              BIOS Data Area or between E0000 and FFFFF (From ACPI Spec.)
- *              Only a 32-bit physical address is necessary.
- *
- *              NOTE2: This function is always available, regardless of the
- *              initialization state of the rest of ACPI.

Subject: [PATCH 0179/1971] ACPICA: Disable all wake GPEs after first one
 recieved

Change for GPE support: when a wake GPE is
received, now all wake GPEs are immediately disabled to
prevent the waking GPE from firing again, and to prevent
other wake GPEs from interrupting the wake process.

From 1ba753acb372c2955a4843302e92e49ce82e2fea Mon Sep 17 00:00:00 2001
From: Bob Moore <robert.moore@intel.com>
Date: Fri, 2 Feb 2007 19:48:20 +0300
Subject: [PATCH 0186/1971] ACPICA: Re-implement interpreters' "serialized
 mode"

Enhanced the implementation of the interpreters'
serialized mode (boot with "acpi_serialize" to set
acpi_glb_all_methods_serialized flag.)
When this mode is specified, instead of creating a serialization
semaphore per control method, the interpreter lock is
simply no longer released before a blocking operation
during control method execution. This effectively makes
the AML Interpreter single-threaded. The overhead of a
semaphore per-method is eliminated.

From 765ec20180fb70b4ee9d730167b2a0b76879f791 Mon Sep 17 00:00:00 2001
From: Bob Moore <robert.moore@intel.com>
Date: Fri, 2 Feb 2007 19:48:20 +0300
Subject: [PATCH 0187/1971] ACPICA: Delete stale FADT functions outside
 tbfadt.c.

Moved all FADT-related functions to a new file, tbfadt.c.
Eliminated the acpi_hw_initialize function - the
FADT registers are now validated when the table is loaded.

Subject: [PATCH 0195/1971] ACPICA: Report error if method creates 2 objects
 with the same name

Fixed a regression where an error was no
longer emitted if a control method attempts to create 2
objects of the same name. This previously and now returns
AE_ALREADY_EXISTS. When this exception occurs, it invokes
the mechanism that will dynamically serialize the control
method to possible prevent future errors. (BZ 440)

From 9bc75cff4919f9d947982d805aed89582a20d04d Mon Sep 17 00:00:00 2001
From: Valery Podrezov <valery.a.podrezov@intel.com>
Date: Fri, 2 Feb 2007 19:48:21 +0300
Subject: [PATCH 0210/1971] ACPICA: Eliminate control method 2-pass
 parse/execute.

Completed an AML interpreter performance enhancement for control method
execution. Previously a 2-pass parse/execution, control methods are now
completely parsed and executed in single pass. This improves overall
interpreter performance by ~25%, reduces code size, and reduces CPU stack use.

From d1fdda83f7c567f376ddd4305833de09f7919ca9 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0211/1971] ACPICA: Fix race condition with AcpiWalkNamespace.

Fixed a problem with a possible race condition between threads executing
AcpiWalkNamespace and the AML interpreter. This condition was removed by
modifying AcpiWalkNamespace to (by default) ignore all temporary
namespace entries created during any concurrent control method execution

Subject: [PATCH 0212/1971] ACPICA: _CID support for PCI Root Bridge detection.

Implemented _CID support for PCI Root Bridge detection. If the _HID
does not match the predefined root bridge IDs, the _CID list (if present)
 is now obtained and also checked for an ID match

From a6823e12ca3f79a8c0f8b2d14976ab2152d117e5 Mon Sep 17 00:00:00 2001
From: Alexey Starikovskiy <alexey.y.starikovskiy@intel.com>
Date: Fri, 2 Feb 2007 19:48:22 +0300
Subject: [PATCH 0225/1971] ACPICA: Fixes for load() operator.

Optimized the Load operator in the case where the source operand is an
operation region. Simply map the operation region memory, instead of
performing a bytewise read.

Subject: [PATCH 0227/1971] ACPICA: Ensure that all structures in acobject.h
 are aligned, via #pragma.

Thus, even if the default compiler setting is non-aligned, the header is compiled
 correctly.

Subject: [PATCH 0232/1971] ACPICA: Removed all 16-bit support.

Support for 16-bit ACPICA has been completely removed since it is
no longer necessary and it clutters the code. All 16-bit macros,
types, and conditional compiles have been removed, cleaning up
and simplifying the code across the entire subsystem.
DOS support is no longer needed since the Linux firmware kit
is now available.

Subject: [PATCH 0239/1971] ACPICA: Allow processor to be declared with the
 Device() instead of Processor()

Allow processor to be declered with the Device(), such as:
Device(CPU1234) {
	Name(_HID, "ACPI007")
	Name(_UID, 1234)
}

From df9e062ad994c4db683377b108c0dbed4690e4b0 Mon Sep 17 00:00:00 2001
From: Eric Moore <eric.moore@lsi.com>
Date: Mon, 29 Jan 2007 09:46:21 -0700
Subject: [PATCH 0251/1971] [SCSI] fusion - serialize target resets in mptsas.c

Fusion firmware requires target reset following hotplug removal event,
with purpose to flush target outstanding request in fw. Current implementation
does the target resets from delayed work tasks, that in heavy load
conditions, take too long to be invoked, resulting in command time outs
This patch will issue target reset immediately from ISR context, and will
queue remaining target resets to be issued after the previous one completes.
The delayed work tasks are spawned during the target reset completion.

Subject: [PATCH 0252/1971] ACPI_NUMA: fix HP IA64 simulator issue with
 extended memory domain

ACPI 3.0 incorporated the SRAT spec, upping the table version to 2,
and extending the size of the proximity domain from 1-byte to 4-bytes.
This extension was into a reserved field that firmware should
set to 0, but the HP simulator had non-zero values there
resulting in unexpected huge numbers.

So mask the domain down to 8-bits for now.
A more general fix will be to check the table version
supplied by firmware and get paranoid about reserved fields.

 hba phys

Return proper sas address to sas transport layer for parent phys that
form a wide port. Current implementation returns a different address
for each phy, incremented by one from the base address.

From: John Keller <jpk@sgi.com>
Date: Tue, 30 Jan 2007 01:17:37 -0500
Subject: [PATCH 0257/1971] Altix: ACPI SSDT PCI device support

Add SN platform support for running with an ACPI
capable PROM that defines PCI devices in SSDT
tables. There is a SSDT table for every occupied
slot on a root bus, containing info for every
PPB and/or device on the bus. The SSDTs will be
dynamically loaded/unloaded at hotplug enable/disable.

Platform specific information that is currently
passed via a SAL call, will now be passed via the
Vendor resource in the ACPI Device object(s) defined
in each SSDT.

From 3e643e77a929202455a0cc868c2030a5ba8d1371 Mon Sep 17 00:00:00 2001
From: John Keller <jpk@sgi.com>
Date: Tue, 30 Jan 2007 01:18:38 -0500
Subject: [PATCH 0258/1971] Altix: Add ACPI SSDT PCI device support (hotplug)

Support for dynamic loading and unloading of ACPI SSDT tables upon slot
hotplugs and unplugs.

On SN platforms, we now represent every populated root bus slot with a single
ACPI SSDT table containing info for every device and PPB attached to the slot.
 These SSDTs are generated by the prom at initial boot and hotplug time.  The
info in these SSDT tables is used by the SN kernel IO "fixup" code (which is
called at boot and hotplug time).

On hotplugs (i.e.  enable_slot()), if running with an ACPI capable prom,
attempt to obtain a new ACPI SSDT table for the slot being hotplugged.  If
successful, add the table to the ACPI namespace (acpi_load_table()) and then
walk the new devices and add them to the ACPI infrastructure (acpi_bus_add()).

On hot unplugs (i.e.  disable_slot()), if running with an ACPI capable prom,
attempt to remove the SSDT table associated with the slot from the ACPI
namespace (acpi_unload_table_id()) and infastructure (acpi_bus_trim()).

From: John Keller <jpk@sgi.com>

 A bug was fixed where the sgi hotplug driver was removing
 the slot's SSDT table from the ACPI namespace a bit too early in
 disable_slot(). Also, we now call acpi_bus_start() subsequent
 to acpi_bus_add().

Write does not trigger this bug because the driver refuses in fixed block
mode writes that are not a multiple of the block size. Read does trigger
it in my system.

The bug is not associated with any specific HBA. st tries to do direct i/o
in fixed block mode with reads that are not a multiple of tape block size.

The patch in this message fixes the st problem by switching to using the
driver buffer up to the next close of the device file in fixed block mode
if the user asks for a read like this.

I don't know why the bug has surfaced only after 2.6.17 although the st
problem is old. There may be another bug in the block subsystem and this
patch works around it. However, the patch fixes a problem in st and in
this way it is a valid fix.

This patch may also fix the bug 7900.

The patch compiles and is lightly tested.

Subject: [PATCH 0270/1971] [SCSI] libsas: Don't BUG when connecting two
 expanders via wide port

libsas: Don't BUG when connecting two expanders via wide port

When a device is connected to an expander, the discovery process goes through
sas_ex_discover_dev to figure out what's attached to the phy.  If it is the
case that the phy being discovered happens to be the second phy of a wide link
to an expander, that discover_dev function will incorrectly call
sas_ex_discover_expander, which creates another sas_port and tries to attach the
other sas_phys to the new port, thus triggering a BUG.  The correct thing to do is
to check the other ex_phys of the expander to see if there's a sas_port for this
sas_phy, and attach the sas_phy to the existing sas_port.

This is easily triggered if one enables the phys of a wide port between
expanders one by one.

This second version of the patch fixes a small regression in the case where
all the phys show up at once and we accidentally try to attach to a port
that hasn't been created yet.

Subject: [PATCH 0271/1971] [SCSI] libsas: Add an LU reset mechanism to the
 error handler

After discussion with andmike and dougg, it seems that the purpose of
eh_device_reset_handler is to issue LU resets, and that
eh_bus_reset_handler would be a more appropriate place for a phy reset.

Subject: [PATCH 0272/1971] [SCSI] aic94xx: Remove TMF result code munging

In asd_initiate_ssp_tmf, the TMF result code is replaced with
TMF_RESP_FUNC_FAILED except when the TMF returns a result code immediately.
However, TMFs can return result codes via an ESCB... yet these codes are
also replaced with "FAILED".  The only values that can fall into that case
are TMF_* codes anyway, so get rid of this code where COMPLETE and SUCCESS
are turned into FAILED.  This also lets us propagate those TMF_* codes up
to the caller.

Subject: [PATCH 0274/1971] [SCSI] scsi_error: Fix lost EH commands

If an EH command times out today, the LLDD's abort handler
will be called to abort the command. It is assumed that this
completes successfully, which can result in the command getting
completed later resulting in an oops. Improve the current
implementation by escalating all the way to host reset if
necessary in order to clean up the EH command.

Subject: [PATCH 0275/1971] [SCSI] aic94xx: update for v28 firmware

These changes work compatibly with the old V17 firmware

Contribution:

   Ed Chim <ed_chim@adaptec.com>
   Gilbert Wu <gilbert_wu@adaptec.com>

Change Log:

1.    Use dword instead of qword to display the value of Connection
State register for debug purpose.

2.    There are some registers location of AIC94xx chip has been changed
according to the new V28 firmware. The patch has redefined the register
location and provided initialization.

3.    The new sequencer firmware v28 for Aic94xx SAS/SATA Linux open
source device driver can be downloaded from
http://www.adaptec.com/NR/exeres/35B611BC-9789-4B5B-82C6-85A2CCA8A46A.htm

Change the parent of cards to be a specific host (a class
device), not the physical controller. This is particularly
useful when the hardware has multiple slots, meaning
multiple hosts.

Subject: [PATCH 0281/1971] mmc: Power quirk for ENE controllers

Support for these devices was broken for 2.6.18-rc1 and later by commit
146ad66eac836c0b976c98f428d73e1f6a75270d, which added voltage level support.

This restores the previous behaviour for these devices by ensuring that when
the voltage is changed, only one write to set the voltage is performed.

It may be that both writes are needed if the voltage is being changed between
two non-zero values or that it's safe to ensure that only one write is done
if the hardware only supports one voltage; I don't know whether either is the
case nor can I test since I have only the one SD reader (1524:0550), and it
supports just the one voltage.

Subject: [PATCH 0282/1971] mmc: Add support for SDHC cards

Thanks to the generous donation of an SDHC card by John Gilmore, and
the surprisingly enlightened decision by the SD Card Association to
publish useful specs, I've been able to bash out support for SDHC. The
changes are not too profound:

i) Add a card flag indicating the card uses block level addressing and
check it in the block driver. As we never took advantage of byte-level
addressing, this simply involves skipping the block -> byte
translation when sending commands.

ii) The layout of the CSD is changed - a set of fields are discarded
to make space for a larger C_SIZE. We did not reference any of the
discarded fields except those related to the C_SIZE.

iii) Read and write timeouts are fixed values and not calculated from
CSD values.

iv) Before invoking SEND_APP_OP_COND, we must invoke the new
SEND_IF_COND to inform the card we support SDHC.

Subject: [PATCH 0283/1971] tifm_sd: alter order of the states in the command
 handler

Previously, stop command was issued right after BRS (block received/sent)
event. Stop command completion event could interfere with the card busy
event, causing miscount of the written blocks.
This patch ensures that stop command issued as last action for a
particular command, after DMA sompletion event and written block
count verification.

 data buffer

Data buffer for PIO transfer used to be mapped in advance with kmap.
Abolish it in favor of on-demand kmap_atomic.

Subject: [PATCH 0285/1971] tifm_sd: Switch software timeout handler from
 work_struct to timer

Two changes are introduced to software timeout handler in order to simplify
its management:
1. The implementation is switched from work_struct to timer
2. Previously, software timeout was rearmed with each interrupt. Now,
current request must complete entirely within timeout interval.

Subject: [PATCH 0286/1971] tifm_sd: fix hardware timeout setup

The register access order when setting hardware timeout was incorrect and
causing problems (wrong timeout intervals). This is now fixed.

Subject: [PATCH 0287/1971] tifm_sd: restructure initialization, removal and
 command handling

In order to support correct suspend and resume several changes were needed:
1. Switch from work_struct to tasklet for command handling. When device
suspend is called workqueues are already frozen and can not be used.
2. Separate host initialization code from driver's probe and don't rely
on interrupts for host initialization. This, in turn, addresses two
problems:
 a) Resume needs to re-initialize the host, but can not assume that
    device interrupts were already re-armed.
 b) Previously, probe will return successfully before really knowing
    the state of the host, as host interrupts were not armed in time.
    Now it uses polling to determine the real host state before returning.
3. Separate termination code from driver's remove. Termination may be caused
by resume, if media changed type or became unavailable during suspend.

to some other card type without notification. Therefore, for each socket
in the change set the following is performed:
1. If there's active device in the socket it's unregistered
2. Media detection is performed
3. If detection recognizes supportable media, new device is registered

This patch also alters some macros and variable names to enhance clarity.

From 7146f0d3bd2bcd0100a5db54f4ba9edc1042fe01 Mon Sep 17 00:00:00 2001
From: Alex Dubov <oakad@yahoo.com>
Date: Mon, 18 Dec 2006 14:20:06 +1100
Subject: [PATCH 0293/1971] tifm_7xx1: switch from workqueue to kthread

As there's only one work item (media_switcher) to handle and it's effectively
serialized with itself, I found it more convenient to use kthread instead of
workqueue. This also allows for a working implementation of suspend/resume,
which were totally broken in the past version.

Subject: [PATCH 0299/1971] mmc: Allow host drivers to specify max block count

Many controllers have an upper limit on the number of blocks that can be
transferred in one request. Allow the host drivers to specify this and make
sure we avoid hitting this limit.

Also change the max_sectors field to avoid confusion. This makes it map
less directly to the block layer limits, but as they didn't apply directly
on MMC cards anyway, this isn't a great loss.

Subject: [PATCH 0300/1971] mmc: Handle wbsd's stupid command list

The wbsd hardware is so incredibly brain damaged that it has an internal
list of commands that result in data transfers. The result being that
commands that aren't on this list aren't supported.

Instead of locking up, waiting for a data interrupt that will never come,
we try to fail a bit more gracefully.

Subject: [PATCH 0301/1971] mmc: Graceful fallback for fancy features

MMC high-speed, wide bus support and SD high-speed
are functions that aren't critical for correct
operation of the card. As such, they shouldn't mark
the card as bad or dead when there is a failure
activating these features.

This is needed in particular on some really stupid
hardware (e.g. Winbond's) where not all data transfer
commands are supported.

Subject: [PATCH 0310/1971] IB: Return qp pointer as part of ib_wc

struct ib_wc currently only includes the local QP number: this matches
the IB spec, but seems mostly useless. The following patch replaces
this with the pointer to qp itself, and updates all low level drivers
and all users.

This has the following advantages:
- Ability to get a per-qp context through wc->qp->qp_context
- Existing drivers already have the qp pointer ready in poll cq, so
  this change actually saves a tiny bit (extra memory read) on data path
  (for ehca it would actually be expensive to find the QP pointer when
  polling a CQ, but ehca does not support SRQ so we can leave wc->qp as
  NULL for ehca)
- Users that need the QP number can still get it through wc->qp->qp_num

Use case:

In IPoIB connected mode code, I have a common CQ shared by multiple
QPs.  To track connection usage, I need a way to get at some per-QP
context upon the completion, and I would like to avoid allocating
context object per work request just to stick a QP pointer into it.
With this code, I can just use wc->qp->qp_context.

Subject: [PATCH 0311/1971] IB/srp: Don't wait for response when QP is in error
 state.

When there is a call to send_tsk_mgmt SRP posts a send and waits for 5
seconds to get a response.

When the QP is in the error state it is obvious that there will be no
response so it is quite useless to wait.  In fact, the timeout causes
SRP to wait a long time to reconnect when a QP error occurs. (Each
abort and each reset_device calls send_tsk_mgmt, which waits for the
timeout).  The following patch solves this problem by identifying the
failure and returning an immediate error code.

Subject: [PATCH 0312/1971] IB: Make sure struct ib_user_mad.data is aligned

Make the untyped data region in ib_user_mad have type u64 so that it
gets aligned properly.  This avoids alignment faults in ib_umad when
casting the data field to an rmpp_mad and accessing the 64-bit tid
field on architectures like ia64.

Subject: [PATCH 0313/1971] RDMA/addr: Handle ethernet neighbour updates during
 route resolution

The iWARP connection manager uses the ib_addr services to do route
resolution (neighbour discovery in the IP world).  The ib_addr
netevent callback routine, however, currently only acts on InfiniBand
neighbour updates.  It needs to act on ethernet neighbour updates as
well.

This patch just removes filtering on device type altogether and will
trigger on any neighour updates where the nud_type is valid.  This
simplifies the code some.

Subject: [PATCH 0314/1971] IB/ehca: Remove use of do_mmap()

This patch removes do_mmap() from ehca:
 - Call remap_pfn_range() for hardware register block
 - Use vm_insert_page() to register memory allocated for completion
   queues and queue pairs
 - The actual mmap() call/trigger is now controlled by user space,
   ie. libehca

Subject: [PATCH 0316/1971] hid: allow force feedback for multi-input devices

Allow hid devices with HID_QUIRK_MULTI_INPUT to have force feedback.
This was previously disabled because there were not any force
feedback drivers for such devices. This will change with my upcoming
patch.

Subject: [PATCH 0317/1971] hid: quirk for multi-input devices with unneeded
 output reports

Add new quirk HID_QUIRK_SKIP_OUTPUT_REPORTS to skip output reports
when enumerating reports on a hid-input device. Add this quirk and
HID_QUIRK_MULTI_INPUT to 0810:0001.

PantherLord Twin USB Joystick, 0810:0001 has separate input reports
for 2 distinct game controllers in the same interface, so it needs
HID_QUIRK_MULTI_INPUT. However, the device also contains one output
report per controller which is used to control the force feedback
function, and we do not want those to appear as separate input
devices as well. The simplest approach seems to be to add a quirk to
skip output reports on 0810:0001, and allow the force feedback
driver to handle those.

Subject: [PATCH 0319/1971] HID: hid debug from hid-debug.h to hid layer

hid-debug.h contains a lot of code, and should not therefore
be a header.

This patch moves the code to generic hid layer as .c source, and
introduces CONFIG_HID_DEBUG to conditionally compile it, instead
of playing with #define DEBUG and including hid-debug.h.

From 7c379146005d277982acde02da44c773de5e7e5a Mon Sep 17 00:00:00 2001
From: Jiri Kosina <jkosina@suse.cz>
Date: Wed, 24 Jan 2007 11:54:19 +0100
Subject: [PATCH 0320/1971] HID: API - fix leftovers of hidinput API in USB HID

hidinput_{open,close}() functions do not belong to usbhid, but
to the generic HID layer. Move them, and fix hooks in struct
hid_device, so that now the callbacks are done to transport-specific
_open() functions, but not input_open() functions.

Subject: [PATCH 0323/1971] HID: move away from DEBUG defines in favor of
 CONFIG_HID_DEBUG

CONFIG_INPUT_DEBUG is non-existent option, so remove anything depending
on it.

Also, as we have new CONFIG_HID_DEBUG, this should be used on places
where ifdef DEBUG was used before.

Suggested by Adrian Bunk.

Subject: [PATCH 0324/1971] USB HID: handle multi-interface devices for Apple
 macbook pro properly

Some HID devices by Apple have both keyboard and mouse interfaces; the
keyboard interface is handled by usbhid, but the mouse (really
touchpad) interface must be handled by the separate 'appletouch'
driver.  Using HID_QUIRK_IGNORE will make hiddev ignore both
interfaces, therefore a new quirk flag to ignore only the mouse
interface is required.

If an fs has already been shut down, a lockfs callback should do nothing.
An fs that's been shut down can't acquire locks or do anything with
respect to the cluster.

Also, remove FIXME comment in withdraw function.  The missing bits of the
withdraw procedure are now all done by user space.

Subject: [PATCH 0326/1971] [DLM] fix resend rcom lock

There's a chance the new master of resource hasn't learned it's the new
master before another node sends it a lock during recovery.  The node
sending the lock needs to resend if this happens.

- A sends a master lookup for resource R to C
- B sends a master lookup for resource R to C
- C receives A's lookup, assigns A to be master of R and
  sends a reply back to A
- C receives B's lookup and sends a reply back to B saying
  that A is the master
- B receives lookup reply from C and sends its lock for R to A
- A receives lock from B, doesn't think it's the master of R
  and sends an error back to B
- A receives lookup reply from C and becomes master of R
- B gets error back from A and resends its lock back to A
  (this resending is what this patch does)
- A receives lock from B, it now sees it's the master of R
  and takes the lock

Subject: [PATCH 0327/1971] [DLM] fix old rcom messages

A reply to a recovery message will often be received after the relevant
recovery sequence has aborted and the next recovery sequence has begun.
We need to ignore replies to these old messages from the previous
recovery.  There's already a way to do this for synchronous recovery
requests using the rc_id number, but not for async.

Each recovery sequence already has a locally unique sequence number
associated with it.  This patch adds a field to the rcom (recovery
message) structure where this recovery sequence number can be placed,
rc_seq.  When a node sends a reply to a recovery request, it copies the
rc_seq number it received into rc_seq_reply.  When the first node receives
the reply to its recovery message, it will check whether rc_seq_reply
matches the current recovery sequence number, ls_recover_seq, and if not
then it ignores the old reply.

An old, inadequate approach to filtering out old replies (checking if the
current stage of recovery has moved back to the start) has been removed
from two spots.

The protocol version number is changed to reflect the different rcom
structures.

Subject: [PATCH 0329/1971] [DLM] fix send_args() lvb copying

The send_args() function is used to copy parameters into a message for a
number different message types.  Only some of those types are set up
beforehand (in create_message) to include space for sending lvb data.
send_args was wrongly copying the lvb for all message types as long as the
lock had an lvb.  This means that the lvb data was being written past the
end of the message into unknown space.

Subject: [PATCH 0330/1971] [DLM] fix receive_request() lvb copying

LVB's are not sent as part of new requests, but the code receiving the
request was copying data into the lvb anyway.  The space in the message
where it mistakenly thought the lvb lived actually contained the resource
name, so it wound up incorrectly copying this name data into the lvb.  Fix
is to just create the lvb, not copy junk into it.

Subject: [PATCH 0331/1971] [DLM] fix lost flags in stub replies

When the dlm fakes an unlock/cancel reply from a failed node using a stub
message struct, it wasn't setting the flags in the stub message.  So, in
the process of receiving the fake message the lkb flags would be updated
and cleared from the zero flags in the message.  The problem observed in
tests was the loss of the USER flag which caused the dlm to think a user
lock was a kernel lock and subsequently fail an assertion checking the
validity of the ast/callback field.

Subject: [PATCH 0333/1971] [GFS2] Fix DIO deadlock

This patch fixes Red Hat bugzilla #212627 in which a deadlock occurs
due to trying to take the i_mutex while holding a glock. The correct
locking order is defined as i_mutex -> glock in all cases.

I've left dealing with allocating writes. I know that we need to do
that, but for now this should do the trick. We don't need to take the
i_mutex on write, because the VFS has already taken it for us. On read
we don't need it since the glock is enough protection. The reason that
I've made some of the checks into a separate function is that we'll need
to do the checks again in the allocating write case eventually, so this
is partly in preparation for this. Likewise the return value test of !=
1 might look a bit odd and thats because we'll need a third return value
in case of requiring an allocation.

I've made the change to deferred mode on the glock to ensure flushing
read caches on other nodes. I notice that (using blktrace to look at
whats going on) we appear to do a better job of large I/Os than ext3
after this patch (in terms of not splitting up the I/Os).

Subject: [PATCH 0334/1971] [GFS2] Fail over to readpage for stuffed files

This is partially derrived from a patch written by Russell Cattelan.
It fixes a bug where there is a race between readpages and truncate
by ignoring readpages for stuffed files. This is ok because a stuffed
file will never be more than one block (minus sizeof(struct gfs2_dinode))
in size and block size is always less than page size, so we do not lose
anything efficiency-wise by not doing readahead for stuffed files. They
will have already been "read ahead" by the action of reading the inode
in, in the first place.

This is the remaining part of the fix for Red Hat bugzilla #218966
which had not yet made it upstream.

Subject: [PATCH 0335/1971] [GFS2] Fix change nlink deadlock

Bugzilla 215088

Fix deadlock in gfs2_change_nlink() while installing RHEL5 into GFS2
partition. The gfs2_rename() apparently needs block allocation for the
new name (into the directory) where it requires rg locks. At the same
time, while updating the nlink count for the replaced file,
gfs2_change_nlink() tries to return the inode meta-data back to resource
group where it needs rg locks too. Our logic doesn't allow process to
acquire these locks recursively by the same process  (RHEL installer)
that results a BUG call. This only happens within rename code path and
only if the destination file exists before the rename operation.

I was a little over-enthusiastic turning schedule() calls int cond_sched() when fixing the DLM for Andrew Morton.

These four should really be calls to schedule() or the dlm can busy-wait.

Subject: [PATCH 0338/1971] [GFS2] Fix ordering of page disposal vs. glock_dq

In case of unlinked files with dirty pages GFS2 wasn't clearing
the pages in quite the right order. This patch clears the pages
earlier (before the qlock_dq) to avoid the situation that the
release of the glock results in attempting to write back data that
has already been deallocated.

This fixes Red Hat bugzilla: #220117

Update the quilt header comments to match the
code changes.

Change gfs2_lookup_simple to return an error in the case
of a NULL inode.
The callers of gfs2_lookup_simple do not check for NULL
in the no entry case and such would end up dereferencing a NULL ptr.

Second round of gfs2_rename lock re-ordering to allow Anaconda adding
root partition on top of gfs2. Previous to this patch the recursive
lock detector in glock.c can be triggered due to attempting to lock
the rgrp twice. This fixes it by checking to see whether the rgrp
is already locked.

Subject: [PATCH 0341/1971] [DLM] change some log_error to log_debug

Some common, non-error messages should use log_debug instead of log_error
so they can be turned off.

From 68c817a1c4e21b893672ac73d8a498e6647453aa Mon Sep 17 00:00:00 2001
From: David Teigland <teigland@redhat.com>
Date: Tue, 9 Jan 2007 09:41:48 -0600
Subject: [PATCH 0342/1971] [DLM] rename dlm_config_info fields

Add a "ci_" prefix to the fields in the dlm_config_info struct so that we
can use macros to add configfs functions to access them (in a later
patch).  No functional changes in this patch, just naming changes.

Subject: [PATCH 0345/1971] [GFS2] gfs2 knows of directories which it chooses
 not to display

This is for Red Hat bugzilla bug bz #222302:

Moving a virtual IP from node to node between two NFS-over-GFS2
servers was causing one of the GFS2 servers to become confused and
reference a deleted inode.  The problem was due to vfs dentries that did
not reference the gfs2_dops and therefore didn't call the gfs2 revalidate
code to revalidate a dentry after a directory had been deleted & recreated.
This patch is a crosswrite from a RHEL4 bug found in GFS1 as
bz #190756 and it is against the latest -nmw git tree.

Subject: [PATCH 0347/1971] [DLM] Use workqueues for dlm lowcomms

This patch converts the DLM TCP lowcomms to use workqueues rather than using its
own daemon functions. Simultaneously removing a lot of code and making it more
scalable on multi-processor machines.

From a1bc86e6bddd34362ca08a3a4d898eb4b5c15215 Mon Sep 17 00:00:00 2001
From: David Teigland <teigland@redhat.com>
Date: Mon, 15 Jan 2007 10:34:52 -0600
Subject: [PATCH 0348/1971] [DLM] fix user unlocking

When a user process exits, we clear all the locks it holds.  There is a
problem, though, with locks that the process had begun unlocking before it
exited.  We couldn't find the lkb's that were in the process of being
unlocked remotely, to flag that they are DEAD.  To solve this, we move
lkb's being unlocked onto a new list in the per-process structure that
tracks what locks the process is holding.  We can then go through this
list to flag the necessary lkb's when clearing locks for a process when it
exits.

Subject: [PATCH 0349/1971] [DLM] fix master recovery

If master recovery happens on an rsb in one recovery sequence, then that
sequence is aborted before lock recovery happens, then in the next
sequence, we rely on the previous master recovery (which may now be
invalid due to another node ignoring a lookup result) and go on do to the
lock recovery where we get stuck due to an invalid master value.

 recovery cycle begins: master of rsb X has left
 nodes A and B send node C an rcom lookup for X to find the new master
 C gets lookup from B first, sets B as new master, and sends reply back to B
 C gets lookup from A next, and sends reply back to A saying B is master
 A gets lookup reply from C and sets B as the new master in the rsb
 recovery cycle on A, B and C is aborted to start a new recovery
 B gets lookup reply from C and ignores it since there's a new recovery
 recovery cycle begins: some other node has joined
 B doesn't think it's the master of X so it doesn't rebuild it in the directory
 C looks up the master of X, no one is master, so it becomes new master
 B looks up the master of X, finds it's C
 A believes that B is the master of X, so it sends its lock to B
 B sends an error back to A
 A resends
 this repeats forever, the incorrect master value on A is never corrected

The fix is to do master recovery on an rsb that still has the NEW_MASTER
flag set from an earlier recovery sequence, and therefore didn't complete
lock recovery.

Subject: [PATCH 0350/1971] [GFS2] Add writepages for "data=writeback" mounts

It occurred to me that although a gfs2 specific writepages for ordered
writes and journaled data would be tricky, by hooking writepages only
for "data=writeback" mounts we could take advantage of not needing
buffer heads (we don't use them on the read side, nor have we for some
time) and create much larger I/Os for the block layer.

Using blktrace both before and after, its possible to see that for large
I/Os, most of the requests generated through writepages are now 1024
sectors after this patch is applied as opposed to 8 sectors before.

Subject: [PATCH 0351/1971] [GFS2] Clean up/speed up readdir

This removes the extra filldir callback which gfs2 was using to
enclose an attempt at readahead for inodes during readdir. The
code was too complicated and also hurts performance badly in the
case that the getdents64/readdir call isn't being followed by
stat() and it wasn't even getting it right all the time when it
was.

As a result, on my test box an "ls" of a directory containing 250000
files fell from about 7mins (freshly mounted, so nothing cached) to
between about 15 to 25 seconds. When the directory content was cached,
the time taken fell from about 3mins to about 4 or 5 seconds.

Interestingly in the cached case, running "ls -l" once reduced the time
taken for subsequent runs of "ls" to about 6 secs even without this
patch. Now it turns out that there was a special case of glocks being
used for prefetching the metadata, but because of the timeouts for these
locks (set to 10 secs) the metadata was being timed out before it was
being used and this the prefetch code was constantly trying to prefetch
the same data over and over.

Calling "ls -l" meant that the inodes were brought into memory and once
the inodes are cached, the glocks are not disposed of until the inodes
are pushed out of the cache, thus extending the lifetime of the glocks,
and thus bringing down the time for subsequent runs of "ls"
considerably.

Subject: [PATCH 0353/1971] [GFS2] Shrink gfs2_inode memory by half

Here is something I spotted (while looking for something entirely
different) the other day.

Rather than using a completion in each and every struct gfs2_holder,
this removes it in favour of hashed wait queues, thus saving a
considerable amount of memory both on the stack (where a number of
gfs2_holder structures are allocated) and in particular in the
gfs2_inode which has 8 gfs2_holder structures embedded within it.

As a result on x86_64 the gfs2_inode shrinks from 2488 bytes to
1912 bytes, a saving of 576 bytes per inode (no thats not a typo!).
In actual practice we get a much better result than that since
now that a gfs2_inode is under the 2048 byte barrier, we get two
per 4k slab page effectively halving the amount of memory required
to store gfs2_inodes.

Subject: [PATCH 0354/1971] [GFS2] Remove the "greedy" function from glock.[ch]

The "greedy" code was an attempt to retain glocks for a minimum length
of time when they relate to mmap()ed files. The current implementation
of this feature is not, however, ideal in that it required allocating
memory in order to do this and its overly complicated.

It also misses the mark by ignoring the other I/O operations which are
just as likely to suffer from the same problem. So the plan is to remove
this now and then add the functionality back as part of the glock state
machine at a later date (and thus take into account all the possible
users of this feature)

Subject: [PATCH 0356/1971] [GFS2] Remove local exclusive glock mode

Here is a patch for GFS2 to remove the local exclusive flag. In
the places it was used, mutex's are always held earlier in the
call path, so it appears redundant in the LM_ST_SHARED case.

Also, the GFS2 holders were setting local exclusive in any case where
the requested lock was LM_ST_EXCLUSIVE. So the other places in the glock
code where the flag was tested have been replaced with tests for the
lock state being LM_ST_EXCLUSIVE in order to ensure the logic is the
same as before (i.e. LM_ST_EXCLUSIVE is always locally exclusive as well
as globally exclusive).

Subject: [PATCH 0358/1971] [GFS2] Tidy up glops calls

This patch doesn't make any changes to the ordering of the various
operations related to glocking, but it does tidy up the calls to the
glops.c functions to make the structure more obvious.

The two functions: gfs2_glock_xmote_th() and gfs2_glock_drop_th() can be
made static within glock.c since they are called by every set of glock
operations. The xmote_th and drop_th glock operations are then made
conditional upon those two routines existing and called from the
previously mentioned functions in glock.c respectively.

Also it can be seen that the go_sync operation isn't needed since it can
easily be replaced by calls to xmote_bh and drop_bh respectively. This
results in no longer (confusingly) calling back into routines in glock.c
from glops.c and also reducing the glock operations by one member.

Subject: [PATCH 0360/1971] [GFS2] Remove queue_empty() function

This function is not longer required since we do not do recursive
locking in the glock layer. As a result all its callers can be
replaceed with list_empty() calls.

Subject: [PATCH 0362/1971] [GFS2] use CURRENT_TIME_SEC instead of get_seconds
 in gfs2

I was looking something else up and came across this...

I don't honestly have a good reason to change it other than to make it
like every other Linux filesystem in this regard.  ;-)  It doesn't
functionally change anything, but makes some lines shorter. :)

I'm also curious; why does gfs2 have 64-bits of on-disk timestamps, but
not in timespec_t format, and only stores second resolutions?  Seems like
you're halfway to sub-second resolutions already.

I suppose if that gets implemented then all of the below should
instead be CURRENT_TIME not CURRENT_TIME_SEC.

Subject: [PATCH 0365/1971] [DLM] saved dlm message can be dropped

dlm_receive_message() returns 0 instead of returning 'error'.  What would
happen is that process_requestqueue would take a saved message off the
requestqueue and call receive_message on it.  receive_message would then
see that recovery had been aborted, set error to EINTR, and 'goto out',
expecting that the error would be returned.  Instead, 0 was always
returned, so process_requestqueue would think that the message had been
processed and delete it instead of saving it to process next time.  This
means the message (usually an unlock in my tests) would be lost.

Subject: [PATCH 0366/1971] [DLM] can miss clearing resend flag

A long, complicated sequence of events, beginning with the RESEND flag not
being cleared on an lkb, can result in an unlock never completing.

- lkb on waiters list for remote lookup
- the remote node is both the dir node and the master node, so
  it optimizes the lookup into a request and sends a request
  reply back
- the request reply is saved on the requestqueue to be processed
  after recovery
- recovery runs dlm_recover_waiters_pre() which sets RESEND flag
  so the lookup will be resent after recovery
- end of recovery: process_requestqueue takes saved request reply
  which removes the lkb off the waitesr list, _without_ clearing
  the RESEND flag
- end of recovery: dlm_recover_waiters_post() doesn't do anything
  with the now completed lookup lkb (would usually clear RESEND)
- later, the node unmounts, unlocks this lkb that still has RESEND
  flag set
- the lkb is on the waiters list again, now for unlock, when recovery
  occurs, dlm_recover_waiters_pre() shows the lkb for unlock with RESEND
  set, doesn't do anything since the master still exists
- end of recovery: dlm_recover_waiters_post() takes this lkb off
  the waiters list because it has the RESEND flag set, then reports
  an error because unlocks are never supposed to be handled in
  recover_waiters_post().
- later, the unlock reply is received, doesn't find the lkb on
  the waiters list because recover_waiters_post() has wrongly
  removed it.
- the unlock operation has been lost, and we're left with a
  stray granted lock
- unmount spins waiting for the unlock to complete

The visible evidence of this problem will be a node where gfs umount is
spinning, the dlm waiters list will be empty, and the dlm locks list will
show a granted lock.

The fix is simply to clear the RESEND flag when taking an lkb off the
waiters list.

Subject: [PATCH 0367/1971] [GFS2] Fix recursive locking attempt with NFS

In certain cases, its possible for NFS to call the lookup code while
holding the glock (when doing a readdirplus operation) so we need to
check for that and not try and lock the glock twice. This also fixes a
typo in a previous NFS related GFS2 patch.

Subject: [PATCH 0368/1971] [GFS2] Fix list corruption in lops.c

The patch below appears to fix the list corruption that we are seeing on
occasion. Although the transaction structure is private to a single
thread, when the queued structures are dismantled during an in-core
commit, its possible for a different thread to be trying to add the same
structure to another, new, transaction at the same time.

To avoid this, this patch takes the log spinlock during this operation.

Increase the number of locks at which point the dlm begins asking gfs to
reduce its lock usage.  The default value is largely arbitrary, but the
current value of 50,000 ends up limiting performance unnecessarily for too
many users.

This patch fixes a circular dependency by letting GFS2_FS_LOCKING_DLM
and DLM depend on instead of select SYSFS.

Since SYSFS depends on EMBEDDED this change shouldn't cause any problems
for users.

Subject: [PATCH 0374/1971] [GFS2] Put back semaphore to avoid umount problem

Dave Teigland fixed this bug a while back, but I managed to mistakenly
remove the semaphore during later development. It is required to avoid
the list of inodes changing during an invalidate_inodes call. I have
made it an rwsem since the read side will be taken frequently during
normal filesystem operation. The write site will only happen during
umount of the file system.

Also the bug only triggers when using the DLM lock manager and only then
under certain conditions as its timing related.

Subject: [PATCH 0375/1971] [GFS2] Fix unlink deadlocks

Move the glock acquisition to outside of the transactions.

Lock odering must be preserved in order to prevent ABBA
deadlocks. The current gfs2_change_nlink code would tries
to grab the glock after having started a transaction and thus is holding
the log lock. This is inconsistent with other code paths in
gfs that grab the resource group glock prior to staring
a tranactions.

One problem with this fix is that the resource group
lock is always grabbed now even if the inode still has

Set saved_max_pfn when discontig memory is in use.

This sets up saved_max_pfn when disctontig memory is in use.
This mirrors the code for contig memory.

This patch does not entirely solve the problem of making vmcore work,
however it does appear to be neccessary. Please consider applying.

Subject: [PATCH 0382/1971] [IA64] kexec: Minor enhancement to includes in
 crash.c

linux/uaccess.h was being included, but it seems that
really the following includes are needed.

asm/page.h: for __va() and PAGE_SHIFT
asm/uaccess.h: for copy_to_user()

I guess that linux/uaccess.h pulls in both asm/page.h and asm/uaccess.h.
I notices this while backporting the code to xen's linux-2.6.16.33,
which does not have linux/uaccess.h. I'm posting it as I think it is a
correct, though somewhat cosmetic fix.

Subject: [PATCH 0389/1971] [S390] cpcmd with vmalloc addresses.

Change the bounce buffer logic of cpcmd. diag8 needs _real_ memory below
2GB. Therefore vmalloced data does not work. As the data might cross a
page boundary, we cannot use virt_to_page either. The solution is to use
virt_to_page only in the check for a bounce buffer.

There was a redundant check for response==NULL. response < 2GB contains
this check as well.

I also removed the rlen==0 check, since rlen=0 and response!=NULL would
be a caller bug and response==NULL is already checked.

Requests are aborted when the sclp interface reports 'not operational'
even though they may still be active at the sclp, leading to concurrent
writes to request memory by both the kernel and the sclp interface.
Do not abort requests for which the sclp interface reports not
operational status during request retry.

Subject: [PATCH 0393/1971] [S390] dasd: fix bug in dasd initialization cleanup

The initialization of the dasd_eer code is one of the last steps of the
dasd driver initialization. When initialization fails in one of the
earlier steps, the dasd_exit function is called to clean up what has been
done so far. So the dasd_eer_exit function may be called, although the
dasd_eer_init function wasn't called before and dasd_eer_exit tries to
unregister a misc device that wasn't registered, which results in a BUG.

Make sure that dasd_eer_exit can be called without initialization. Use a
dynamically allocated struct miscdevice instead of a static one, so we
only try to unregister the device if it exists and was actually registered.

cpu_relax() has barrier() semantics hence there is no need to use both
of them in conjunction in sclp_sync_wait(). Also change cpu_relax()
so it's more obvious that it has barrier semantics.

Subject: [PATCH 0401/1971] [S390] dasd: fix unconditional reserve handling.

The reserve/release IOCTLs sometimes do not work. If second system
does a 'steal lock' the pending unit check (Format 3 Msg F) is
delivered. Since ERP is disabled for reserve/release, the IOCTL call
fails. We have to allow basic ERP (retries) for reserve/release IOCTLs.

kretprobe_trampoline_holder() is in kprobes section but used to
register a kprobe in arch_init_kprobes(). Hence register_kprobe()
and therefore arch_init_kprobes() will fail.

Subject: [PATCH 0406/1971] [S390] cio: Catch operand exceptions on stsch.

If we have a subchannel id which has been generated via
for_each_subchannel(), it might contain an invalid subchannel set id.
We need to catch the ensuing operand exception by using stsch_err()
instead of stsch() in all possible cases.

Subject: [PATCH 0411/1971] [S390] move crypto options and some cleanup.

This patch moves the config options for the s390 crypto instructions
to the standard "Hardware crypto devices" menu. In addition some
cleanup has been done: use a flag for supported keylengths, add a
warning about machien limitation, return ENOTSUPP in case the
hardware has no support, remove superfluous printks and update
email addresses.

From c1821c2e9711adc3cd298a16b7237c92a2cee78d Mon Sep 17 00:00:00 2001
From: Gerald Schaefer <geraldsc@de.ibm.com>
Date: Mon, 5 Feb 2007 21:18:17 +0100
Subject: [PATCH 0412/1971] [S390] noexec protection

This provides a noexec protection on s390 hardware. Our hardware does
not have any bits left in the pte for a hw noexec bit, so this is a
different approach using shadow page tables and a special addressing
mode that allows separate address spaces for code and data.

As a special feature of our "secondary-space" addressing mode, separate
page tables can be specified for the translation of data addresses
(storage operands) and instruction addresses. The shadow page table is
used for the instruction addresses and the standard page table for the
data addresses.
The shadow page table is linked to the standard page table by a pointer
in page->lru.next of the struct page corresponding to the page that
contains the standard page table (since page->private is not really
private with the pte_lock and the page table pages are not in the LRU
list).
Depending on the software bits of a pte, it is either inserted into
both page tables or just into the standard (data) page table. Pages of
a vma that does not have the VM_EXEC bit set get mapped only in the
data address space. Any try to execute code on such a page will cause a
page translation exception. The standard reaction to this is a SIGSEGV
with two exceptions: the two system call opcodes 0x0a77 (sys_sigreturn)
and 0x0aad (sys_rt_sigreturn) are allowed. They are stored by the
kernel to the signal stack frame. Unfortunately, the signal return
mechanism cannot be modified to use an SA_RESTORER because the
exception unwinding code depends on the system call opcode stored
behind the signal stack frame.

This feature requires that user space is executed in secondary-space
mode and the kernel in home-space mode, which means that the addressing
modes need to be switched and that the noexec protection only works
for user space.
After switching the addressing modes, we cannot use the mvcp/mvcs
instructions anymore to copy between kernel and user space. A new
mvcos instruction has been added to the z9 EC/BC hardware which allows
to copy between arbitrary address spaces, but on older hardware the
page tables need to be walked manually.

From d54853ef8cb17296ac7bce9c77430fb7c80532d0 Mon Sep 17 00:00:00 2001
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
Date: Mon, 5 Feb 2007 21:18:19 +0100
Subject: [PATCH 0413/1971] [S390] ETR support.

This patch adds support for clock synchronization to an external time
reference (ETR). The external time reference sends an oscillator
signal and a synchronization signal every 2^20 microseconds to keep
the TOD clocks of all connected servers in sync. For availability
two ETR units can be connected to a machine. If the clock deviates
for more than the sync-check tolerance all cpus get a machine check
that indicates that the clock is out of sync. For the lovely details
how to get the clock back in sync see the code below.

Subject: [PATCH 0414/1971] [S390] Support for s390 Pseudo Random Number
 Generator

Starting with the z9 the CPU Cryptographic Assist Facility comes with
an integrated Pseudo Random Number Generator. The generator creates
random numbers by an algorithm similar to the ANSI X9.17 standard.
The pseudo-random numbers can be accessed via a character device driver
node called /dev/prandom. Similar to /dev/urandom any amount of bytes
can be read from the device without blocking.

From cced1dd42ebcebc7fa7f02fe487e48aa71752401 Mon Sep 17 00:00:00 2001
From: Michael Holzheu <holzheu@de.ibm.com>
Date: Mon, 5 Feb 2007 21:18:26 +0100
Subject: [PATCH 0416/1971] [S390] Add crypto support for 3592 tape devices

3592 tape devices are able to write data encrpyted on tape mediums.
This z/Linux device driver support includes the following functions:
 * ioctl to switch on/off encryption
 * ioctl to query encryption status of drive
 * ioctls to set and query key encrypting keys (kekls)
 * long busy interrupt handling

From 31cb4bd31a48f62105d037ad53192b94d4c08f53 Mon Sep 17 00:00:00 2001
From: Michael Holzheu <holzheu@de.ibm.com>
Date: Mon, 5 Feb 2007 21:18:29 +0100
Subject: [PATCH 0417/1971] [S390] Hypervisor filesystem (s390_hypfs) for z/VM

This is an extension of the already existing hypfs for LPAR (DIAG 204).
Data returned by DIAG 2fc is exported using the s390_hypfs when Linux
is running under z/VM. Information about cpus and memory is provided.
Data is put into different virtual files which can be accessed from user
space. All values are represented as ASCII strings

From 31ee4b2f40994e8b21691f85cdd4052551a789b7 Mon Sep 17 00:00:00 2001
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
Date: Mon, 5 Feb 2007 21:18:31 +0100
Subject: [PATCH 0418/1971] [S390] Calibrate delay and bogomips.

Preset the bogomips number to the cpu capacity value reported by
store system information in SYSIB 1.2.2. This value is constant
for a particular machine model and can be used to determine
relative performance differences between machines.

From ab14de6c37fae22911ba99f4171613e6d758050b Mon Sep 17 00:00:00 2001
From: Heiko Carstens <heiko.carstens@de.ibm.com>
Date: Mon, 5 Feb 2007 21:18:37 +0100
Subject: [PATCH 0419/1971] [S390] Convert memory detection into C code.

Hopefully this will make it more maintainable and less error prone.
Code makes use of search_exception_tables(). Since it calls this
function before the kernel exeception table is sorted, there is an
early call to sort_main_extable().

This way it's easy to use the already present infrastructure of fixup
sections. Also this would allows to easily convert the rest of
head[31|64].S into C code.

Subject: [PATCH 0420/1971] [S390] Mark kernel text section read-only.

Set read-only flag in the page table entries for the kernel image text
section. This will catch all instruction caused corruptions withing the
text section.
Instruction replacement via kprobes still works, since it bypasses now
dynamic address translation.

Subject: [PATCH 0422/1971] [IA64] kexec: Move machine_shutdown from
 machine_kexec.c to process.c

This moves the ia64 implementation of machine_shutdown() from
machine_kexec.c to process.c, which is in keeping with the implelmentation
on other architectures, and seems like a much more appropriate home for it.

Subject: [PATCH 0423/1971] [IA64] enable singlestep on system call

As is pointed out in
http://www.gelato.org/community/view_linear.php?id=1_1036&from=authors&value=Ian%20Wienand#1_1039,
if single step on break instruction, the break fault has higher
priority than the single-step trap. When the break fault handler
is entered, it advances the IP by 1 instruction so break instruction
single-stepping is skipped, actually it is next instruction which
is single stepped.

This patch modifies this, it adds TIF_SINGLESTEP bit for thread
flags, and generate a fake sigtrap when single stepping break
instruction. Test case in attachment can verify this. Any comments
is welcome.

Subject: [PATCH 0424/1971] [IA64] use snprintf() on features field of
 /proc/cpuinfo

Some patches have turned up on xen-devel recently to convert strcpy()
to safer alternatives and so forth.  While reviewing those patches
I noticed that the features string building could be cleaned up.

This patch uses snprintf() instead of strcpy() and direct character
pointer manipulation.  It makes the features string building safe and
gets rid of the special case for features output in show_cpuinfo()

Additionally I removed the (int) cast of ARRAY_SIZE, which seems to
serve no purpose.

Unfortunately the read-free MSI interrupt handler needs to flush write

thus becomes a lot more simpler since we don't need to track link state
anymore.

This fix attempts to solve a customer (IBM) reported issue with NAPI
enabled e1000 having bad performance when transmitting simultaneously
on four ports.  The issue comes down to an interaction between NAPI,
hardware interrupt balancing, and the driver rescheduling poll on
the same processor.  Try to fix by allowing the driver to re-enable
interrupts sooner instead of polling one more time, when there was
recently all the work completed in cleanup.

Since the driver sets the IP checksum insertion bit (IXSM in Status

bits of any garbage so as not to confuse the hardware.

The driver was still mis-calculating the number of bytes sent during
transmit, now the driver computes what appears to be exactly 100%
correct byte counts (not including CRC) when figuring out how many
bytes and frames were sent during the current transmit packet.

Subject: [PATCH 0435/1971] [PATCH] zd1211rw: Consistency for address space
 constants

The zd1211rw address space has confused me once too many times. This
patch introduces the following naming notation:

Memory space is split into segments (cr, fw, eeprom) and segments may
contain components (e.g. boot code inside eeprom). These names are
arbitrary and only for the description below:

x_START: Absolute address of segment start
(previously these were named such as CR_BASE_OFFSET, but they weren't
really offsets unless you were considering them as an offset to 0)

x_LEN: Segment length

x_y_LEN: Length of component y of segment x

x_y_OFFSET: Relative address of component y into segment x. The absolute
address for this component is (x_START + x_y_OFFSET)

I also renamed EEPROM registers to EEPROM data. These 'registers' can't
be written to using standard I/O and really represent predefined data
from the vendor.

From 0ce34bc8f7d906d66ce6803f63399ef9bbe54012 Mon Sep 17 00:00:00 2001
From: Daniel Drake <dsd@gentoo.org>
Date: Tue, 12 Dec 2006 01:26:11 +0000
Subject: [PATCH 0436/1971] [PATCH] zd1211rw: Remove addressing abstraction

Instead of passing our own custom 32-bit addresses around and
translating them, this patch makes all our register address constants
absolute and removes the translation.

There are two ugly parts:
 - fw_reg_addr() is needed to compute addresses of firmware registers, as this
   is dynamic based upon firmware
 - inc_addr() needs a small hack to handle byte vs word addressing

However, both of those are only small, and we don't use fw_regs a whole
lot anyway.

The bonuses here include simplicity and improved driver readability. Also, the
fact that registers are now referenced by 16-bit absolute addresses (as
opposed to 32-bit pseudo addresses) means that over 2kb compiled code size has
been shaved off.

Includes some touchups and sparse fixes from Ulrich Kunitz.

Date: Sat, 30 Dec 2006 23:30:32 -0600
Subject: [PATCH 0439/1971] [PATCH] bcm43xx: Interrogate hardware-enable switch
 and update LEDs

The current bcm43xx driver ignores any wireless-enable switches on mini-PCI
and mini-PCI-E cards. This patch implements a new routine to interrogate the
radio hardware enabled bit in the interface, logs the initial state and any
changes in the switch (if debugging enabled), activates the LED to show the
state, and changes the periodic work handler to provide 1 second response
to switch changes and to account for changes in the periodic work specs.

Subject: [PATCH 0440/1971] [PATCH] prism54: add ethtool -i interface

Add support for "ethtool -i" to prism54 driver.

ethtool -i queries the specified device for
associated driver information.

This helps tools like Fedora's system-config-network to
provide GUI management of network devices.
I learned how to write this patch by reading the ipw2100
driver code.

Subject: [PATCH 0441/1971] [PATCH] softmac: avoid assert in
 ieee80211softmac_wx_get_rate

Unconfigured bcm43xx device can hit an assert() during wx_get_rate
queries.  This is because bcm43xx calls ieee80211softmac_start late
(i.e. during open instead of probe).

   bcm43xx_net_open ->
      bcm43xx_init_board ->
         bcm43xx_select_wireless_core ->
            ieee80211softmac_start

Fix is to check that device is running before completing
ieee80211softmac_wx_get_rate.

Subject: [PATCH 0448/1971] chelsio: useless test in cxgb2::remove_one

pci_get_drvadata() is necessarily distinct from NULL if
cxgb2::init_one succeeded. cxgb2::remove_one is solely
issued through the PCI device callback.

Subject: [PATCH 0450/1971] chelsio: tabulate the update of the statistic
 counters

Let's try to avoid some code duplication.

- cxgb2
  The data are contiguous. Use plain memcpy.

- ixf1010/pm3393/vsc7326
  The cast of &mac->stats to (u64 *) is not wonderful but it is not clear
  if it is worth to add an ad-hoc union under the struct cmac_statistics.

vsc7326_reg.h suggests that more statistics could be available.

Subject: [PATCH 0451/1971] Spidernet DMA coalescing

The current driver code performs 512 DMA mappings of a bunch of
32-byte ring descriptor structures. This is silly, as they are
all in contiguous memory. This patch changes the code to
dma_map_coherent() each rx/tx ring as a whole.

This patch adds net_ratelimit to many of the printks in order to
limit extraneous warning messages (created in response to Bug 28554).
This patch supercedes all previous ratelimit patches.
This has been tested, please apply.

Subject: [PATCH 0453/1971] Spidernet remove rxramfull tasklet

Get rid of the rxramfull tasklet, and let the NAPI poll routine
deal with this situation. (The rxramfull interrupt is simply
stating that the h/w has run out of room for incoming packets).

From: Cesar Eduardo Barros <cesarb@cesarb.net>

Subject: [PATCH 0466/1971] driver for Silan SC92031 netdev

This is a driver for the Silan SC92031/Rsltek 8139D NIC chip.

This chip is found on at least one counterfeit Encore ENL832-TX-RENT NIC
[1], which came with a mini-CD with the 2.4 driver.  A slightly older
version of the driver was found at [2].  The main difference between them
is that the newer one has a small bugfix in the RX path, a lot of
gratuitous renaming of functions, all the printable strings changed to show
as a "Rsltek 8139D" [sic], and a PCI ID of 8139 instead of 2031.  The
driver on this patch is a rewrite of the vendor drivers (based mostly on
the older one).

Changes from the previous patch sent to netdev:
- Use MMIO instead of PIO
- Changed TX bounce buffers allocation
- Use skb_copy_and_csum_dev
- Several small bug fixes
- Tested for more than just a few minutes each time

[1] See http://www.encore-usa.com/faq.php under ENL832-TX-RENT for more
    information
[2] Look for SL_LINUX.ZIP (which is really a .tar.gz) at
    http://broadbandforum.in/dataone_Intex_LAN_cardlinux-t4207-s15.html
[3] To compile on 2.6.17, simply add back the last argument to the
    interrupt handler in two places, and copy the boolean declarations
    from 2.6.19

From 95f48a71a254fa81ae4be1307ce3bb8361521a7d Mon Sep 17 00:00:00 2001
From: Adrian Bunk <bunk@stusta.de>
Date: Tue, 19 Dec 2006 13:08:48 -0800
Subject: [PATCH 0467/1971] remove the broken SKMC driver

The SKMC driver has:
- already been marked as BROKEN in 2.6.0 three years ago and
- is still marked as BROKEN.

Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.

But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.

-  	unfortunately there seem to be newer MC2+ boards that react
-  	on IRQ 3/5/9/10 instead of 3/5/10/11, so we have to autoprobe
-  	in questionable cases...
-  Dec 28th, 1999
-	integrated patches from David Weinehall & Bill Wendling for 2.3
-	kernels (isa_...functions).  Things are defined in a way that
-        it still works with 2.0.x 8-)
-  Dec 30th, 1999
-	added handling of the remaining interrupt conditions.  That
-        should cure the spurious hangs.
-  Jan 30th, 2000
-	newer kernels automatically probe more than one board, so the
-	'startslot' as a variable is also needed here
-  June 1st, 2000
-	added changes for recent 2.3 kernels

Subject: [PATCH 0469/1971] forcedeth: ring access

This patch modifys ring access by using pointers. This avoids computing
the current index and avoids accessing the base address of the rings.

Subject: [PATCH 0472/1971] make hdlc_setup() static again

hdlc_setup was exported, but this export was never used.

If a driver using it actually shows up it can still be exported again.

Subject: [PATCH 0476/1971] remove the broken OAKNET driver

The OAKNET driver:
- has been marked as BROKEN for more than two years and
- is still marked as BROKEN.

Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.

But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.

Subject: [PATCH 0478/1971] bonding.h: "extern inline" -> "static inline"

"extern inline" generates a warning with -Wmissing-prototypes and I'm
currently working on getting the kernel cleaned up for adding this to
the CFLAGS since it will help us to avoid a nasty class of runtime
errors.

If there are places that really need a forced inline, __always_inline
would be the correct solution.

Subject: [PATCH 0480/1971] bonding: fix device name allocation error

	The code to select names for the bonding interfaces was, for the
non-sysfs creation case, always using a hard-coded set of bond0, bond1,
etc, up to max_bonds.  This caused conflicts for the second or
subsequent loads of the module.

	Changed the code to obtain device names from dev_alloc_name().

Subject: [PATCH 0482/1971] bonding: modify sysfs support to permit multiple
 loads

	The existing code would blindly attempt to create the
bonding_masters file (in /sys/class/net) every time the module was
loaded.  When the module is loaded multiple times (which is the
historical method used by initscripts and sysconfig to create multiple
bonding interfaces), this caused load failure of the second module load
attempt, as the creation request would fail.

	This changes the code to note the failure, arrange to not remove
the bonding_masters file upon module exit, and then return success.

	Bonding interfaces created by the second or subsequent loads of
the module will not exist in bonding_masters.  This is not a significant
change, as previously only the interfaces from the most recent load of
the module would be listed.  Both situations are less than optimal, but
this case permits compatibility with existing distro configuration
scripts, and is consistent.

	Note that previously, the sysfs create request would overwrite
the exsting bonding_masters file and succeed, allowing multiple loads of
the module.  The sysfs code has recently changed to return an error if
the file being created already exists.

	Patrick McHardy <kaber@trash.net>, who reported this problem,
observed crashes on the old kernel (before sysfs checked for
duplicates).  I did not experience such crashes, but this change should
resolve them.

Subject: [PATCH 0485/1971] forcedeth: tx limiting

This patch optimizes the logic for tx limiting. It adds a flag to check
on the completion side instead of recalculating the number of empty
slots. Also, it removes the fields that were previous used for limiting
since they have no value.

Subject: [PATCH 0486/1971] forcedeth: tx data path optimization

This patch optimizes the tx data paths and cleans up the code (removes
vlan from descr1/2 since only valid for desc3, changes to make code
easier to read, etc).

Subject: [PATCH 0489/1971] forcedeth: tx max work

This patch adds a limit to how much tx work can be done in each
iteration of tx processing. If the max limit is reached, remaining tx
completions will be handled by timer interrupt.

Subject: [PATCH 0495/1971] sky2: software rx/tx stats

Maintain packet statistics in software rather than hardware.
This is slightly slower, but allows easier debugging of problems
where packets are still being received by PHY but not being handled
by hardware.

Subject: [PATCH 0506/1971] cxgb3 - Remove BUG_ON from t3b_intr_napi

In some cases, SG_DATA_INTR won't clear on read and the following
interrupt may cause us to assert because NAPI is already scheduled.
Remove the assertion, NAPI can handle attempts to rearm it while
it's already scheduled.

Subject: [PATCH 0510/1971] s2io: Making LRO and UFO as module loadable
 parameter.

This patch adds two load parameters napi and ufo. Previously NAPI was
compilation option with these changes wan enable disable NAPI using load
parameter. Also we are introducing ufo load parameter to enable/disable
ufo feature

From: Sivakumar Subramani <Sivakumar.Subramani@neterion.com>
Date: Wed, 31 Jan 2007 13:32:57 -0500
Subject: [PATCH 0512/1971] s2io: Fixes in updating skb->truesize and code
 cleanup.

1. Fix for updating skb->truesize properly.
2. Disable NAPI only if more than one ring configured in case of MSI/MSI-X
   interrupts. Previously we were disabling NAPI irrespective of number of
   rings when MSI/MSI-X interrupts were used.
3. Code cleanup.

Subject: [PATCH 0516/1971] [IA64] find thread for user rbs address

I encountered one problem when running ptrace test case the situation
is this: traced process's syscall parameter needs to be accessed, but
for sys_clone system call with clone_flag (CLONE_VFORK | CLONE_VM |
SIGCHLD) parameter.  This syscall's parameter accessing result is wrong.

The reason is that vforked child process mm point is the same, but
tgid is different. Without this patch find_thread_for_addr will return
vforked process if vforked process is also stopped, but not the thread
which calls vfork syscall.

Subject: [PATCH 0517/1971] [IA64] Fix NULL-pointer dereference in
 ia64_machine_kexec()

This patch fixes a NULL-pointer dereference in ia64_machine_kexec().

The variable ia64_kimage is set in machine_kexec_prepare() which is
called from sys_kexec_load(). If kdump wasn't configured before,
ia64_kimage is NULL.  machine_kdump_on_init() passes ia64_kimage() to
machine_kexec() which assumes a valid value.

The patch also adds a few sanity checks for the image to simplify
debugging of similar problems in future.

Subject: [PATCH 0519/1971] [IA64] Clear IRQ affinity when unregistered

When we offline a CPU, migrate_irqs() tries to determine whether the
affinity bits of the IRQ descriptor match any of the remaining online
CPUs.  If not, it fixes up the interrupt to point somewhere else.
Unfortunately, if an IRQ is unregistered the IRQ descriptor may still
have affinity to the CPU being offlined, but the no_irq_chip handler
doesn't provide a set_affinity function.  This causes us to hit the
WARN_ON in migrate_irqs().

The easiest solution seems to be setting all the bits in the affinity
mask when the last interrupt is removed from the vector.  I hit this on
an older kernel with Xen/ia64 using driver domains (so it probably needs
more testing on upstream).  Xen essentially uses the bind/unbind
interface in sysfs to unregister a device from a driver and thus
unregister the interrupt.

Subject: [PATCH 0523/1971] [IA64] register memory ranges in a consistent
 manner

While pursuing and unrelated issue with 64Mb granules I noticed a problem
related to inconsistent use of add_active_range.  There doesn't appear any
reason to me why FLATMEM versus DISCONTIG_MEM should register memory to
add_active_range with different code.  So I've changed the code into a
common implementation.

The other subtle issue fixed by this patch was calling add_active_range in
count_node_pages before granule aligning is performed.  We were lucky with
16MB granules but not so with 64MB granules.  count_node_pages has reserved
regions filtered out and as a consequence linked kernel text and data
aren't covered by calls to count_node_pages.  So linked kernel regions
wasn't reported to add_active_regions.  This resulted in free_initmem
causing numerous bad_page reports.  This won't occur with this patch
because now all known memory regions are reported by
register_active_ranges.

Subject: [PATCH 0524/1971] [IA64] alignment bug in ldscript

Occasionally the FSYS_RETURN patch list can have an odd length, causing other
data structures to get out of alignment.  In OpenVZ it is odd and we get
misaligned kernel image, which does not boot.

- broken multiple inclusion in include/asm-x86_64/swiotlb.h
- missing call to mark_clean in swiotlb_sync_sg()
- a (perhaps only theoretical) issue in swiotlb_dma_supported() when
io_tlb_end is exactly at the end of memory

From: Jan Beulich <jbeulich@novell.com>
Date: Mon, 5 Feb 2007 18:51:25 -0800
Subject: [PATCH 0532/1971] [IA64] swiotlb cleanup

- add proper __init decoration to swiotlb's init code (and the code calling
  it, where not already the case)

- replace uses of 'unsigned long' with dma_addr_t where appropriate

- do miscellaneous simplicfication and cleanup

Subject: [PATCH 0534/1971] [GFS2] nfsd readdirplus assertion failure

Glock assertion failure found in '07 NFS connectathon. One of the NFSDs
is doing a "readdirplus" procedure call. It passes the logic into
gfs2_readdir() where it obtains its directory inode glock. This is then
followed by filehandle construction that invokes lookup code. It hits
the assertion failure while trying to obtain the inode glock again
inside gfs2_drevalidate().

This patch bypasses the recursive glock call if caller already holds the
lock.

Date: Mon, 8 Jan 2007 02:14:29 +0900
Subject: [PATCH 0536/1971] [MIPS] Define MIPS_CPU_IRQ_BASE in generic header

The irq_base for {mips,rm7k,rm9k}_cpu_irq_init() are constant on all
platforms and are same value on most platforms (0 or 16, depends on
CONFIG_I8259).  Define them in asm-mips/mach-generic/irq.h and make
them customizable.  This will save a few cycle on each CPU interrupt.

A good side effect is removing some dependencies to MALTA in generic
SMTC code.

Although MIPS_CPU_IRQ_BASE is customizable, this patch changes irq
mappings on DDB5477, EMMA2RH and MIPS_SIM, since really customizing
them might cause some header dependency problem and there seems no
good reason to customize it.  So currently only VR41XX is using custom
MIPS_CPU_IRQ_BASE value, which is 0 regardless of CONFIG_I8259.

Testing this patch on those platforms is greatly appreciated.  Thank
you.

From 2fa7937bd8922e1fe4aae6a45e7e787fa45d6043 Mon Sep 17 00:00:00 2001
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
Date: Sun, 14 Jan 2007 23:41:42 +0900
Subject: [PATCH 0537/1971] [MIPS] Make I8259A_IRQ_BASE customizable

Move I8259A_IRQ_BASE from asm/i8259.h to asm/mach-generic/irq.h and
make it really customizable.  And remove I8259_IRQ_BASE declared on
some platforms.  Currently only NEC_CMBVR4133 is using custom
I8259A_IRQ_BASE value.

From c44e8d5e47b8ba672440b92eab0735628469116c Mon Sep 17 00:00:00 2001
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
Date: Sat, 30 Dec 2006 00:43:59 +0900
Subject: [PATCH 0538/1971] [MIPS] prom_free_prom_memory cleanup

Current prom_free_prom_memory() implementations are almost same as
free_init_pages(), or no-op.  Make free_init_pages() extern (again)
and make prom_free_prom_memory() use it.

From a583158c9ce822c96a718fbf877cec1e5f9ad75d Mon Sep 17 00:00:00 2001
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
Date: Mon, 18 Dec 2006 00:07:40 +0900
Subject: [PATCH 0539/1971] [MIPS] Unify memset.S

The 32-bit version and 64-bit version are almost equal.  Unify them.
This makes further improvements (for example, supporting CDEX, etc.)
easier.

Subject: [PATCH 0540/1971] [MIPS] Setup min_low_pfn/max_low_pfn correctly

This patch makes a better usage of these two globals.
'min_low_pfn' is now correctly setup for all configs, which
allow us to rely on it in boot memory code init.

Subject: [PATCH 0541/1971] [MIPS] FLATMEM: introduce PHYS_OFFSET.

The old code was assuming that min_low_pfn was always 0. This
means that platforms having a big hole at their memory start
paid the price of wasting some memory for the allocation of
unused entries in mem_map[].

This patch prevents this waste.

It introduces PHYS_OFFSET define which is the start of the
physical memory and uses it wherever needed. Specially when
converting physical/virtual addresses into virtual/physical
ones.

Currently all platforms defines PHYS_OFFSET to 0.

Subject: [PATCH 0551/1971] [MIPS] Remove superfluous "ifdef CONFIG_KGDB".

Given that the Makefiles involved already have conditional compilation of
 the form:

  obj-$(CONFIG_KGDB)      += dbg_io.o

there seems to be little value for the dbg_io.c source files to check
that config variable yet again.

Subject: [PATCH 0562/1971] [MIPS] SELinux: Add security hooks to mips-mt
 {get,set}affinity

This patch adds LSM hooks into the setaffinity and getaffinity functions
for the mips architecture to enable security modules to control these
operations between tasks with different security attributes. This
implementation uses the existing task_setscheduler and task_getscheduler
LSM hooks.

Subject: [PATCH 0570/1971] [MIPS] Alchemy:  Fix PCI-memory access

The problem was introduced in 2.6.18.3 with the casting of some
36bit-defines (PCI memory) in au1000.h to resource_size_t which may be
u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT.

With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed
because the ioremap in arch/mips/au1000/common/pci.c already used the
truncated addresses.
With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan
aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c
fails because the maximum iomem-address is 0xffffffff (32bit) but the
pci-memory-start-address is 0x440000000 (36bit).

To get pci working again, I propose the following patch:

1. remove the resource_size_t-casting from au1000.h again
2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and
necessary here. The 36bit-handling will be done in __fixup_bigphys_addr).

With this patch pci works again like in 2.6.18.2, the gcc-compile warnings
in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

Subject: [PATCH 0577/1971] [CRYPTO] all: Check for usage in hard IRQ context

Using blkcipher/hash crypto operations in hard IRQ context can lead
to random memory corruption due to the reuse of kmap_atomic slots.
Since crypto operations were never meant to be used in hard IRQ
contexts, this patch checks for such usage and returns an error
before kmap_atomic is performed.

Subject: [PATCH 0578/1971] [CRYPTO] tcrypt: Added test vectors for
 sha384/sha512

This patch adds tests for SHA384 HMAC and SHA512 HMAC to the tcrypt module. Test data was taken from
RFC4231. This patch is a follow-up to the discovery (bug 7646) that the kernel SHA384 HMAC
implementation was not generating proper SHA384 HMACs.

Subject: [PATCH 0581/1971] [CRYPTO] tcrypt: Removed vestigial crypto_alloc_tfm
 call

The crypto_comp conversion missed the last remaining crypto_alloc_tfm
call.  This patch replaces it with crypto_alloc_comp.

Subject: [PATCH 0584/1971] [CRYPTO] api: Allow multiple frontends per backend

This patch adds support for multiple frontend types for each backend
algorithm by passing the type and mask through to the backend type
init function.

Subject: [PATCH 0586/1971] [CRYPTO] api: Use structs for cipher/compression

Now that all cipher/compression users have switched over to the new
allocation scheme, we can get rid of the compatility defines and use
proper structs for them.

Subject: [PATCH 0596/1971] [PATCH] kbuild: correctly skip tilded backups in
 localversion files

 Tildes as in path as in filenames are handled correctly now:
 only files, containing tilde '~', are backups, thus are not valid.

 [KJ]:
 Definition of `space' was removed, scripts/Kbuild.include has one.
 That definition was taken right from the GNU make manual, while Kbuild's
 version is original.

Subject: [PATCH 0597/1971] [PATCH] Keys: Fix key serial number collision
 handling

Fix the key serial number collision avoidance code in key_alloc_serial().

This didn't use to be so much of a problem as the key serial numbers were
allocated from a simple incremental counter, and it would have to go through
two billion keys before it could possibly encounter a collision.  However, now
that random numbers are used instead, collisions are much more likely.

This is fixed by finding a hole in the rbtree where the next unused serial
number ought to be and using that by going almost back to the top of the
insertion routine and redoing the insertion with the new serial number rather
than trying to be clever and attempting to work out the insertion point
pointer directly.

This fixes kernel BZ #7727.

Subject: [PATCH 0599/1971] skge: handle zero address at open

Some motherboards are broken and have no address set. Failing at probe time
prevents the device from ever being used (like to download a fixed BIOS). Instead
warn on probe and check again when device is brought up. That way the address
can be set.

This makes cpm uart able to work using OF-passed parameters
in case of CPM stuff (found on most mpc8xx reference and custom
boards). The idea is to keep ppc stuff working yet making it able to be
used for powerpc.

Subject: [PATCH 0611/1971] [POWERPC] 8xx: platform specific mmu updates

This is just a straight port of the same done in arch/ppc
by Marcelo Tosatti. One used to be
[PATCH] ppc32 8xx: update_mmu_cache() needs unconditional tlbie,
commit eb07d964b4491d1bb5864cd3d7e7633ccdda9a53

In a nutshell, the board is nearly stuck without this, yet without any
visible failure - being just very slow.

Subject: [PATCH 0612/1971] [POWERPC] 8xx: generic 8xx code arch/powerpc port

Including support for non-coherent cache, some mm-related things +
relevant field in Kconfig and Makefiles. Also included rheap.o compilation
if 8xx is defined.

Non-coherent mapping were refined and renamed according to Cristoph
Hellwig. Orphaned functions were cleaned up.

[Also removed arch/ppc/kernel/dma-mapping.c, because otherwise
compiling with ARCH=ppc for a non DMA-cache-coherent platform ends up
with two copies of __dma_alloc_coherent etc.

Subject: [PATCH 0614/1971] [POWERPC] 8xx: powerpc port of core CPM PIC

This covers common CPM access functions, CPM interrupt controller code,
micropatch and a few compatibility things to kee the same driver base
working with arch/ppc. This version is refined with all the comments
(mostly PIC-related) addressed.

+ * process is reset, we reclaim the memory available.  There is
+ * currently no deallocator for this memory.
+ * The amount of space available is platform dependent.  On the
+ * MBX, the EPPC software loads additional microcode into the
+ * communication processor, and uses some of the DP ram for this
+ * purpose.  Current, the first 512 bytes and the last 256 bytes of
+ * memory are used.  Right now I am conservative and only use the
+ * memory that can never be used for microcode.  If there are
+ * applications that require more DP ram, we can expand the boundaries
+ * but then we have to be careful of any downloaded microcode.

From df34403dcaacef541a67c955aebc37c51f53ca7c Mon Sep 17 00:00:00 2001
From: Vitaly Bordug <vbordug@ru.mvista.com>
Date: Wed, 24 Jan 2007 22:41:42 +0300
Subject: [PATCH 0615/1971] [POWERPC] 8xx: Add mpc885ads support and common
 mpc8xx files

This adds the core 8xx stuff and specifically mpc885ads board-specific
bits to arch/powerpc. Respective Kconfig has been cleaned up from the stuff
not yet ported over to avoid confusion. Updated and cleaned version.

Subject: [PATCH 0619/1971] [POWERPC] pSeries: EEH improperly enabled for some
 Power4 systems

It appears that EEH is improperly enabled for some Power4 systems.
On these systems, the ibm,set-eeh-option returns a value of success
even when EEH is not supported on the given node. Thus, an explicit
check for support is required.

During boot, on power4, without this patch, one sees messages
similar to:

EEH: event on unsupported device, rc=0 dn=/pci@400000000110/IBM,sp@1
EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2
EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2,2
etc.

The patch makes these go away.

Without this patch, EEH recovery does seem to work correctly for
at least some devices (I tested ethernet e1000), but fails to
recover others (the Emulex LightPulse LPFC, most notably).
Off the top of my head, I don't remember why some devices are
affected, but not others.

The PAPR indicates that the correct way to test for EEH is as
done in this patch; its not clear to me if this was in the PAPR
all along, or recently added; if it was there all along, its not
clear to me why this hadn't been fixed long ago. I suspect only
certain firmware levels are affected.

Date: Fri, 26 Jan 2007 19:07:47 -0800
Subject: [PATCH 0620/1971] [POWERPC] ps3: repository misc fixes

Various fixes for the PS3 repository code:

  - Sync signatures of function prototypes and implementations (enum vs.
    unsigned int)
  - Correct references to `regions' as `registers':
      o Correct enum ps3_region_type as enum ps3_reg_type,
      o Correct PS3_REGION_TYPE_* as PS3_REG_TYPE_*,
      o Correct ps3_repository_find_region() as ps3_repository_find_reg().
  - Correct function name in pr_debug() call
  - Minor error condition improvements.

Subject: [PATCH 0621/1971] [POWERPC] ps3: repository storage support

Handle storage-related repository data:
  - Add missing implementations of ps3_repository_read_stor_*() repository
    accessors.
  - Dump storage properties in debug mode
  - Add PS3_DEV_TYPE_STOR_{DISK,ROM,FLASH} device types (which are identical to
    the corresponding SCSI device types) to enum ps3_dev_type

Subject: [PATCH 0622/1971] [POWERPC] ps3: system bus minor mmio fix

Fix two minor bugs in the PS3 system bus mmio region code.  First, on error or
when freeing a region, retain the bus_addr and len fields to allow subsequent
calls to create the region.  Second, correct the region address argument to the
lv1_unmap_device_mmio_region() call.

Fixes modprobe/rmmod of some drivers.

Subject: [PATCH 0625/1971] [POWERPC] ps3: smp interrupt fixes

PS3 fixups for interrups on SMP.

Fixes the alignment of the interrupt status bitmap, changes the hypervisor
interrupt calls to the '_ext' versions that take an explicit processor
thread ID.

From: Geoff Levand <geoffrey.levand@am.sony.com>
Date: Fri, 26 Jan 2007 19:08:08 -0800
Subject: [PATCH 0627/1971] [POWERPC] ps3: bind interrupt to cpu

Change the PS3 irq allocation routines to take an argument indicating which
cpu (processor thread) the interrupt should be serviced on.

The current system configuration favors device interrupts that are serviced
on cpu0, so that is used as the default.

Subject: [PATCH 0628/1971] [POWERPC] ps3: add interrupt alloc for outlets

PS3 interrupt core update:
  - Add ps3_alloc_irq() and ps3_free_irq(), to allocate a virtual interrupt
    number for an interrupt outlet, which is needed by the PS3 GPU frame
    buffer device and audio drivers

Subject: [PATCH 0635/1971] [POWERPC] Fix array indexing error in rheap grow()

The grow() function in the rheap library allocates a larger array of blocks,
copies the contents of the old blocks array to the newly allocated array and
fixes the list_head pointers after the copy.  At the end, the new blocks must
be enqueued to the empty_list of the rh_info_t structure.  This patch fixes
a bug where the code was indexing past the end of the array when enqueueing
blocks.  The UCC ethernet driver, which uses the rheap allocator, experiences
kernel panics because of this bug.

Subject: [PATCH 0636/1971] [POWERPC] Oprofile cleanup

Clean up the ctr_read/write a bit. It's currently defined in the
include but only used in one C file each. The only exception is the
classic version, so keep that in the include and define in the C file
as appropriate.

From 1bd2e5ae18a8f93333707d81d3dbd9209a255137 Mon Sep 17 00:00:00 2001
From: Olof Johansson <olof@lixom.net>

Subject: [PATCH 0637/1971] [POWERPC] Add PMC type to cputable

Add cputable entries for which type of PMC implementation the processor
has.

I've only filled in the current 64-bit processors, the unfilled default
value will have same behaviour as before so it can be done over time
as needed.

Also tidy up the dummy_perf implementation a bit, aggregating it into
one function with ifdefs instead of several.

Subject: [PATCH 0638/1971] [POWERPC] Introduce _SYSDEV_ATTR

Introduce _SYSDEV_ATTR(), to be used to just define the struct, and not a
named variable with the attribute. Useful for arrays of sysdev_attributes.

Support for PA6T-style PMC registers.

PMCs are completely implementation-dependent on PPC, and PA6T numbers them
differently from the IBM model.

Subject: [PATCH 0640/1971] [POWERPC] MPIC: support more than 256 sources

Allow more than the default 256 MPIC sources. Allocates a new flag
(MPIC_LARGE_VECTORS) to be used by platform code when instantiating
the mpic.

I picked 11 bits worth right now since it would cover the number of
sources on any hardware I have seen. It can always be increased later
if needed.

Subject: [PATCH 0646/1971] [POWERPC] cpm2: CPM2 interrupt controller fix

This contains important fixes for the CPM2 PIC code. Eliminated
CPM_IRQ_OFFSET, pulling the respective interrupt numbers from the interrupt
mapping. Updated devicetree files to reflect that. Changed direct
IC-related IO accesses to the IO accessors. Fixed all the sense values to
keep coherency with ipic. In the current code, CPM2 stuff will have no IRQs
and hence could be hardly usable.

From 5427828e83b7f3c000eaec1cfb09c9bc4d024ad1 Mon Sep 17 00:00:00 2001
From: Vitaly Bordug <vbordug@ru.mvista.com>
Date: Wed, 31 Jan 2007 02:09:00 +0300
Subject: [PATCH 0647/1971] [POWERPC] Fix kernel build errors for mpc8272ads
 and mpc8560ads

Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the
current kernel. Current patch fixes it, as well as other inconsistencies
expressed, that do not permit targets from working properly:

- Updated dts with a chosen node with interrupt controller,
- fixed messed device IDs among CPM2 SoC devices,
- corrected odd header name and fixed type in defines,
- Added 82xx subdir to the powerpc/platforms Makefile, missed during
  initial commit,
- new solely-powerpc header file for 8260 family (was using one from
  arch/ppc, this one cleaned up from the extra stuff), in fact for now
  a placeholder to get the board-specific includes for stuff not yet
  capable to live with devicetree peeks only
- Fixed couple of misprints in reference mpc8272 dts.

Subject: [PATCH 0648/1971] [POWERPC] mpc8272ads: defconfig

Default config file for mpc8272ads (powerpc port).Though relevant bits went
in, it is required to keep proper default configuration for the target,
which seems to be missed initially.

Subject: [PATCH 0649/1971] [POWERPC] 86xx: local_irq_disable() is redundant
 after local_irq_save()

arch/powerpc/platforms/86xx/mpc86xx_smp.c::smp_86xx_kick_cpu() contains
local_irq_disable() call after local_irq_save(). This looks
redundant.

Subject: [PATCH 0658/1971] [POWERPC] Celleb: consolidate spu management ops

Spu management ops in arch/platforms/cell/spu_priv1_mmio.h can be used
commonly in of based platform. This patch separates spu management ops
from native cell code and uses on celleb platform.

Subject: [PATCH 0662/1971] [POWERPC] Assign all PCI busses on G3 Blue & White

G3 Blue & White is misconfigured by default so that CardBus controllers
in PCI slots don't work.  The PCI bridge is programmed to only allow
access to bus 1 but not higher busses.

The patch forces the PCI busses to be reassigned if a Grackle controller
is found and the machine identifies itself as "PowerMac1,1"

Subject: [PATCH 0668/1971] [POWERPC] pasemi: Configure DMA controller
 interrupts

The DMA controller on PWRficient is somewhat special -- has a PCI header
so it looks like it's on the root PCI (-Express) root bus, but it uses
more than the default number of interrupts (and they are hardwired).

We need to wire up all interrupts for the DMA controller. The generic
IRQ code will only map the primary interrupt from the PCI header (128),
so add 129->211 by hand.

Subject: [PATCH 0671/1971] [POWERPC] Maple: use mmio nvram

Some systems supported by the maple platform (e.g. JS2x blades running
SLOF) are able to use the mmio_nvram backend for reading and writing
nvram.  This is an improvement over the current situation -- no nvram
access from userspace at all.

Select MMIO_NVRAM for the maple platform.

Initialize the mmio_nvram backend from maple setup code.

Subject: [PATCH 0673/1971] [POWERPC] Fix performance monitor exception

To the issue: some point during 2.6.20 development, Paul Mackerras
introduced the "lazy IRQ  disabling" patch (very cool work,  BTW).
In that patch, the performance monitor unit exception was marked as
"maskable", in the sense that if interrupts were soft-disabled, that
exception could be ignored.  This broke my PowerPC profiling code.
The symptom that I see is that a varying number of interrupts
(from 0 to $n$, typically closer to 0) get delivered, when, in
reality, it should always be very close to $n$.

The issue stems from the way masking is being done.   Masking in
this fashion seems to  work well with the decrementer and external
interrupts, because they are raised again until "really"  handled.
For the PMU, however, this does not apply (at least on my Xserver
machine with a 970FX processor).  If the PMU exception is not handled,
it will _not_ be re-raised (at least on my machine).  The documentation
states that the PMXE bit in MMCR0 is set to 0 when the PMU exception
is raised.  However, software must re-set the bit to re-enable PMU
exceptions.  If the exception is ignored (as currently) not only is
that interrupt lost, but because software does not re-set PMXE, the
PMU registers are "frozen" forever.

[This patch means that performance monitor exceptions are taken and
handled even if irqs are off, as long as some other interrupt hasn't
come along and caused interrupts to be hard-disabled.  In this sense
the PMU exception becomes like an NMI.  The oprofile code for most
powerpc processors does nothing that is unsafe in an NMI context, but
the Cell oprofile code does a spin_lock_irqsave.  However, that turns
out to be OK because Cell doesn't actually use the performance
monitor exception; performance monitor interrupts come in as a
regular interrupt on Cell, so will be disabled when irqs are off.

Subject: [PATCH 0674/1971] [POWERPC] Clear RI bit in MSR before restoring r13
 when returning to userspace

Some instruction tracing tools use the RI (recoverable interrupt) bit
in the MSR to indicate when it's safe to single-step.  Currently we
clear RI after restoring r13 when returning to userspace.  However,
if we single-step past the point where r13 is restored, we'll corrupt
r13 in the exception entry code and not restore it.  This moves the
clearing of RI to just before r13 is restored so this doesn't happen.

Subject: [PATCH 0675/1971] [POWERPC] Make pSeries use the H_BULK_REMOVE
 hypervisor call

H_BULK_REMOVE lets us remove 4 entries from the MMU hash table with one
hypervisor call.  This uses it in pSeries_lpar_hpte_invalidate so we
can tear down mappings with fewer hypervisor calls.

Subject: [PATCH 0677/1971] [POWERPC] Enable interrupts if we are doing fp math
 emulation

Anytime we are emulating an instruction we are going to be doing some form of
get_user() to get the instruction image to decode.  Since get_user() might
sleep we need to ensure we have interrupts enabled or we might see something
like:

Debug: sleeping function called from invalid context at arch/powerpc/kernel/traps.c:697
in_atomic():0, irqs_disabled():1
Call Trace:
[D6023EB0] [C0007F84] show_stack+0x58/0x174 (unreliable)
[D6023EE0] [C0022C34] __might_sleep+0xbc/0xd0
[D6023EF0] [C000D158] program_check_exception+0x1d8/0x4fc

--- Exception: 700 at 0x102a7100
    LR = 0xdb9ef04

However, we want to ensure that interrupts are disabled when handling a trap
exception that might be used for a kernel breakpoint.  This is why ProgramCheck
is marked as EXC_XFER_STD instead of EXC_XFER_EE.

Subject: [PATCH 0678/1971] [POWERPC] Fixup error handling when emulating a
 floating point instruction

When we do full FP emulation its possible that we need to post a SIGFPE based
on the results of the emulation.  The previous code ignored this case completely.

Additionally, the Soft_emulate_8xx case had two issues.  One, we should never
generate a SIGFPE since the code only does data movement.  Second, we were
interpreting the return codes incorrectly, it returns 0 on success, 1 on
illop and -EFAULT on a data access error.

Subject: [PATCH 0681/1971] hpt366: rework rate filtering

- Rework hpt3xx_ratemask() and hpt3xx_ratefilter() so that the former
  returns the max.  mode computed at the load time and doesn't have to do
  bad Ultra33 drive list lookups anymore; remove the duplicate code from
  the latter function.  Move the quirky drive list lookup into
  hpt3xx_quirkproc() where it should have been from the start...

- Disable UltraATA/100 for HPT370 by default as the 33 MHz ATA clock
  being used does not allow for it, and this *greatly* increases the
  transfer speed.

- Save some space by using byte-wide fields in struct hpt_info; switch to
  reading the 8-bit PCI revision ID reg.  only, not the whole 32-bit reg.

- Start incrementing the driver version number with each patch (should
  have been done from the first one posted).

Subject: [PATCH 0683/1971] hpt366: print the real chip name at startup

- Rework the driver setup code so that it prefixes the driver startup
  messages with the real chip name.

- Print the measured f_CNT value and the DPLL setting for non-HPT3xx
  chips as well.

- Claim the extra 240 bytes of I/O space for all chips, not only for
  those having PCI device ID of 0x0004.

Subject: [PATCH 0684/1971] hpt366: switch to using pci_get_slot

Switch to using pci_get_slot() to get to the function 1 of HPT36x/374 chips --
there's no need for the driver itself to walk the list of the PCI devices, and
it also forgets to check the bus number of the device found.

Subject: [PATCH 0685/1971] hpt366: cache channel's MCR address

Begin the real driver redesign. For the starters:

- cache the offset of the IDE channel's MISC. control registers which are used
   throughout the driver in hwif->select_data;

- only touch the relevant MCR when detecting the cable type on HPT374's
   function 1;

- make HPT36x's speedproc handler look the same way as HPT37x ones; fix the
   PIO timing register mask for HPT37x.

- rename all the HPT3xx register related variables consistently; clean up the
   whitespace.

From 26ccb802ee3f9a1f1fd5bc6abf38f124bfbd9cb2 Mon Sep 17 00:00:00 2001
From: Sergei Shtylyov <sshtylyov@ru.mvista.com>

Subject: [PATCH 0686/1971] hpt366: merge HPT37x speedproc handlers

Continue with the driver rewrite:

- move the interrupt twiddling code from the speedproc handlers into the
    init_hwif_hpt366 which allows to merge the two HPT37x speedproc handlers
    into one;

- get rid of in init_hpt366 which solely consists of the duplicate code, then
    fold init_hpt37x() into init_chipset_hpt366();

- fix hpt3xx_tune_drive() to always set the PIO mode requested, not the best
    possible one, change hpt366_config_drive_xfer_rate() accordingly, simplify
    it a bit;

- group all the DMA related code together init_hwif_hpt366(), and generally
    clean up and beautify it.

Subject: [PATCH 0687/1971] hpt366: clean up DMA timeout handling for HPT370

Clean up DMA timeout handling for HPT370:

- hpt370_lostirq_timeout() cleared the DMA status which made __ide_dma_end()
   called afterwards return the incorrect result, and the DMA engine was reset
   both before and after stopping DMA while the HighPoint drivers only do it
   after (which seems logical) -- fix this and also rename the function;

- get rid of the needless mutual recursion in hpt370_ide_dma_end() and
   hpt370_ide_dma_timeout();

- get rid of hpt370_lostirq_timeout() since hwif->ide_dma_end() called from
   the driver's interrupt handler later does all its work.

Subject: [PATCH 0688/1971] hpt366: init code rewrite

Finally, rework the driver init.  code to correctly handle all the chip
variants HighPoint has created so far.  This should cure the rest of the
timing issues in the driver (especially, on 66 MHz PCI) caused by the
HighPoint's habit of switching the base DPLL clock with every new revision
of the chips...

  - switch to using the enumeration type to differ between the numerous chip
    variants, matching PCI device/revision ID with the chip type early, at the
    init_setup stage;

  - extend the hpt_info structure to hold the DPLL and PCI clock frequencies,
    stop duplicating it for each channel by storing the pointer in the pci_dev
    structure: first, at the init_setup stage, point it to a static "template"
    with only the chip type and its specific base DPLL frequency, the highest
    supported DMA mode, and the chip settings table pointer filled, then, at
    the init_chipset stage, allocate per-chip instance  and fill it with the
    rest of the necessary information;

  - get rid of the constant thresholds in the HPT37x PCI clock detection code,
    switch  to calculating  PCI clock frequency based on the chip's base DPLL
    frequency;

  - switch to using the DPLL clock and enable UltraATA/133 mode by default on
    anything newer than HPT370/A;

  - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(),
    unify the HPT36x/37x setup code and the speedproc handlers by joining the
    register setting lists into the table indexed by the clock selected;

  - add enablebits for all the chips to avoid touching disabled channels
    (though the HighPoint BIOS seem to only disable the primary one on
    HPT371/N);

  - separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
    when setting an UltraDMA mode in hpt37x_tune_chipset().

This version has been tested on HPT370/302/371N.

Thanks to Alan for the inspiration. Hopefully, his libata driver will also
benefit from the work done on this "obsolete" driver...

From 6273d26a5b280cb96b804424de323560b301ca51 Mon Sep 17 00:00:00 2001
From: Sergei Shtylyov <sshtylyov@ru.mvista.com>
Date: Wed, 7 Feb 2007 18:18:20 +0100
Subject: [PATCH 0689/1971] hpt366: HPT36x PCI clock detection fix

Fix minor coding mistake in the HPT36x PCI clock detection code noticed by
Bartlomiej Zolnierkiewicz -- it always reported 33 MHz due to the missing
'break' statements.  This, however, most probably never mattered -- in fact, I
was thinking of removing the 25/40 MHz cases completely since HPT36x BIOSes
didn't seem to set any other value than 7 into the 'cmd_high_time' field, i.e.
 supported only 33 MHz PCI.

Note that in the original driver there was another bug: 25 and 40 MHz cases
were interchanged.  Since the 'cmd_high_time' field is in units of PCI clocks,
a lower clock count just *cannot* correspond to a higher frequency, i.  e.  it
should be 5 for 25 MHz PCI and 9 for 40 MHz PCI, not the other way around.

Subject: [PATCH 0690/1971] piix: fix 82371MX enablebits

According to the datasheet, Intel 82371MX (MPIIX) actually has only a
single IDE channel mapped to the primary or secondary ports depending on
the value of the bit 14 of the IDETIM register at PCI config.  offset 0x6C
(the register at 0x6F which the driver refers to.  doesn't exist).  So,
disguise the controller as dual channel and set enablebits masks/values
such that only either primary or secondary channel is detected enabled.
Also, preclude the IDE probing code from reading PCI BARs, this controller
just doesn't have them (it's not the separate PCI function like the other
PCI controllers), it only decodes the legacy addresses.

[ Alan sayeth " MPIIX does not work with or without the change.  It needs its
  own different driver and not to use setup-pci.  Huge job and since it works
  well with libata who cares.  Ditto the early PIIX chip." ]

Subject: [PATCH 0691/1971] piix: tuneproc() fixes/cleanups

Fix/cleanup the driver's tuneproc() and ratemask() methods:

- PPE, IE, and TIME bits need to be cleared beforehand for the slave drive as
  well as master (Alan probably just forgot about it);

- this driver only supports PIO modes up to 4, so must pass the correct limit
  to ide_get_best_pio_mode();

- use min_t() macro instead of min();

- simplify slave vs master drive evaluation;

- do come coding and formatting cleanups...

Subject: [PATCH 0692/1971] slc90e66: carry over fixes from piix driver

Synchronize with version 0.46 of the Intel PIIX/ICH driver:

- carry over Alan's and my own fixes in the tuneproc() method and my cleanups
  both there and in the ratemask() method;

- SLC90E66 only supports MW DMA modes 1/2 and SW DMA mode 2 (just like Intel
  chips), so don't claim support for other MW/SW DMA modes;

- don't check dor non-NULL drive->id in the ide_dma_check() method -- this is
  assumed to be true in all other drivers;

- do some coding/formatting cleanups while at it...

Subject: [PATCH 0693/1971] pdc202xx_new: remove useless code

Remove the following useless fragments from the driver:

- the ide_dma_lostirq() and ide_dma_timeout() handlers which boil down to just
  printing the incoherent reset message and calling their default counterparts;

- check for non-NULL drive->id in the ide_dma_check() handler -- this is assumed
  to be true by all other handlers (also, get rid of unnecessary nesting of the
  conditional statements there);

- the comment before pdcnew_tune_drive() which has nothing to do with the code.

Subject: [PATCH 0695/1971] ide: add Toshiba TC86C001 IDE driver (take 2)

This is the driver for the Toshiba TC86C001 GOKU-S PCI IDE controller,
completely reworked from the original brain-damaged Toshiba's 2.4 version.

This single channel UltraDMA/66 controller is very simple in programming,
yet Toshiba managed to plant many interesting bugs in it.  The particularly
nasty "limitation 5" (as they call the errata) caused me to abuse the IDE
core in a possibly most interesting way so far.  However, this is still
better than the #ifdef mess in drivers/ide/ide-io.c that the original
version included (well, it had much more mess)...

Date: Wed, 7 Feb 2007 18:19:26 +0100
Subject: [PATCH 0700/1971] ide: it8213 IDE driver update (version 2)

* set ATAPI/IORDY/TIME bits correctly in it8213_tuneproc()
* fix UDMA/MWDMA/SWDMA masks in it8213_init_hwif()
* in it8213_tune_chipset() SWDMA2 mode should be used instead of MWDMA0
* backport various fixes from piix/slc90e66 drivers:
  - in it8213_tuneproc() the highest possible PIO mode is PIO4 (not PIO5)
  - clear ATAPI/IORDY/TIME bits before setting them also for slave device
  - use ->speedproc in it8213_config_drive_for_dma()
  - don't try to tune PIO in config_chipset_for_pio()
  - simplify is_slave calculation in it8213_tuneproc()
  - misc cleanups
* fix it8213_ratemask() and it8213_tuneproc() comments
* simplify it8213_init_hwif()
* remove init_chipset_it8213()
* add missing Copyrights and update MODULE_AUTHOR()
* CodingStyle cleanups
* remove dead code

v2:
* PCI_DEVICE_ID_ITE_8213 is only defined in -mm kernels,
  so just use PCI Device ID (0x8213) directly
* fix ->ultra_mask incorrectly changed to 0x3f in v1 version of the patch

Bart, here's a driver I've been keeping out-of-tree for the past couple
of years.  This is for the Delking/Lexar/ASKA/etc.. 32-bit cardbus IDE
CompactFlash adapter card.

It's probably way out of sync with the latest driver model (??), but it
still builds/works.  I'm not interested in doing much of a rewrite, other
than for libata someday, as I no longer use the card myself.

But lots of other people do seem to use it, so it might be nice to see it
"in-tree".

Subject: [PATCH 0702/1971] ACPI support for IDE devices

This patch implements ACPI integration for generic IDE devices.
The ACPI spec mandates that some methods are called during suspend and
resume. And consequently there most modern Laptops cannot resume
properly without it.

According to the spec, we should call '_GTM' (Get Timing) upon suspend
to store the current IDE adapter settings.
Upon resume we should call '_STM' (Set Timing) to initialize the
adapter with the stored settings; afterwards '_GTF' (Get Taskfile)
should be called which returns a buffer with some IDE initialisation
commands. Those commands should be passed to the drive.

There are two module params which control the behaviour of this patch:

'ide=noacpi'
	Do not call any ACPI methods (Disables any ACPI method calls)
'ide=acpigtf'
	Enable execution of _GTF methods upon resume.
	Has no effect if 'ide=noacpi' is set.
'ide=acpionboot'
	Enable execution of ACPI methods during boot.
	This might be required on some machines if 'ide=acpigtf' is
	selected as some machines modify the _GTF information
	depending on the drive identification passed down with _STM.

Subject: [PATCH 0706/1971] Driver core: convert SPI code to use struct device

Converts from using struct "class_device" to "struct device" making
everything show up properly in /sys/devices/ with symlinks from the
/sys/class directory.

Subject: [PATCH 0708/1971] driver core: Remove device_is_registered() in
 device_move().

device_is_registered() will always be false for a device with no bus. Remove
this check and trust the caller to know what they're doing.

Subject: [PATCH 0709/1971] driver core: Allow device_move(dev, NULL).

If we allow NULL as the new parent in device_move(), we need to make sure
that the device is placed into the same place as it would if it was
newly registered:

- Consider the device virtual tree. In order to be able to reuse code,
  setup_parent() has been tweaked a bit.
- kobject_move() can fall back to the kset's kobject.
- sysfs_move_dir() uses the sysfs root dir as fallback.

Date: Mon, 15 Jan 2007 11:50:02 -0800
Subject: [PATCH 0712/1971] PCI: add the sysfs driver name to all modules

This adds the module name to all PCI drivers, if they are built into the
kernel or not.  It will show up in /sys/modules/MODULE_NAME/drivers/

It also fixes up the IDE core, which was calling __pci_register_driver()
directly.

Subject: [PATCH 0718/1971] driver core: Don't stop probing on ->probe errors.

Don't stop on the first ->probe error that is not -ENODEV/-ENXIO.

There might be a driver registered returning an unresonable return code, and
this stops probing completely even though it may make sense to try the next
possible driver. At worst, we may end up with an unbound device.

Subject: [PATCH 0720/1971] Driver core: fix race in sysfs between
 sysfs_remove_file() and read()/write()

This patch prevents a race between IO and removing a file from sysfs.
It introduces a list of sysfs_buffers associated with a file at the inode.
Upon removal of a file the list is walked and the buffers marked orphaned.
IO to orphaned buffers fails with -ENODEV. The driver can safely free
associated data structures or be unloaded.

This is due to sysfs_hash_and_remove() holding dir->d_inode->i_mutex

which in turn takes node->i_mutex.

Subject: [PATCH 0724/1971] sysfs: error handling in sysfs, fill_read_buffer()

if a driver returns an error in fill_read_buffer(), the buffer will be
marked as filled. Subsequent reads will return eof. But there is
no data because of an error, not because it has been read.
Not marking the buffer filled is the obvious fix.

Subject: [PATCH 0728/1971] Driver core: add device_type to struct device

This allows us to add type specific attributes, uevent vars and
release funtions.

A subsystem can carry different types of devices like the "block"
subsys has disks and partitions. Both types create a different set
of attributes, but belong to the same subsystem.

This corresponds to the low level objects:
  kobject   -> device       (object/device data)
  kobj_type -> device_type  (type of object/device we are embedded in)
  kset      -> class/bus    (list of objects/devices of a subsystem)

Whilst the ipw driver should be using the async interface of
the firmware loader to make this a non-issue, this is a minimal fix.

Subject: [PATCH 0731/1971] sysfs: Shadow directory support

The problem.  When implementing a network namespace I need to be able
to have multiple network devices with the same name.  Currently this
is a problem for /sys/class/net/*.

What I want is a separate /sys/class/net directory in sysfs for each
network namespace, and I want to name each of them /sys/class/net.

I looked and the VFS actually allows that.  All that is needed is
for /sys/class/net to implement a follow link method to redirect
lookups to the real directory you want.

Implementing a follow link method that is sensitive to the current
network namespace turns out to be 3 lines of code so it looks like a
clean approach.  Modifying sysfs so it doesn't get in my was is a bit
trickier.

I am calling the concept of multiple directories all at the same path
in the filesystem shadow directories.  With the directory entry really
at that location the shadow master.

The following patch modifies sysfs so it can handle a directory
structure slightly different from the kobject tree so I can implement
the shadow directories for handling /sys/class/net/.

Subject: [PATCH 0732/1971] ocfs2_dlm: fix cluster-wide refcounting of lock
 resources

This was previously broken and migration of some locks had to be temporarily
disabled. We use a new (and backward-incompatible) set of network messages
to account for all references to a lock resources held across the cluster.
once these are all freed, the master node may then free the lock resource
memory once its local references are dropped.

Subject: [PATCH 0734/1971] ocfs2_dlm: Fixes race between migrate and dirty

dlmthread was removing lockres' from the dirty list
and resetting the dirty flag before shuffling the list.
This patch retains the dirty state flag until the lists
are shuffled.

Subject: [PATCH 0736/1971] ocfs2_dlm: Fix migrate lockres handler queue
 scanning

The migrate lockres handler was only searching for its lock on
migrated lockres on the expected queue. This could be problematic
as the new master could have also issued a convert request
during the migration and thus moved the lock to the convert queue.
We now search for the lock on all three queues.

Subject: [PATCH 0737/1971] ocfs2_dlm: Flush dlm workqueue before starting to
 migrate

This is to prevent the condition in which a previously queued
up assert master asserts after we start the migration. Now
migration ensures the workqueue is flushed before proceeding
with migrating the lock to another node. This condition is
typically encountered during parallel umounts.

Subject: [PATCH 0739/1971] ocfs2_dlm: Dlm dispatch was stopping too early

dlm_dispatch_work was not processing the queued up tasks at
the first sign of the node leaving the domain leading to not
only incompleted tasks but also a mismatch in the dlm refcnt.

Subject: [PATCH 0740/1971] ocfs2_dlm: wake up sleepers on the lockres
 waitqueue

The dlm was not waking up threads waiting on the lockres wait queue,
waiting for the lockres to be no longer be in the DLM_LOCK_RES_IN_PROGRESS
and the DLM_LOCK_RES_MIGRATING states.

Subject: [PATCH 0742/1971] ocfs2_dlm: Cookies in locks not being printed
 correctly in error messages

The dlm encodes the node number and a sequence number in the lock cookie.
It also stores the cookie in the lockres in the big endian format to avoid
swapping 8 bytes on each lock request. The bug here was that it was assuming
the cookie to be in the cpu format when decoding it for printing the error
message. This patch swaps the bytes before the print.

Subject: [PATCH 0743/1971] ocfs2: Added post handler callable function in
 o2net message handler

Currently o2net allows one handler function per message type. This
patch adds the ability to call another function to be called after
the handler has returned the message to the other node.

Handlers are now given the option of returning a context (in the form of a
void **) which will be passed back into the post message handler function.

Subject: [PATCH 0744/1971] ocfs2_dlm: Calling post handler function in assert
 master handler

This patch prevents the dlm from sending the clear refmap message
before the set refmap. We use the newly created post function handler
routine to accomplish the task.

Subject: [PATCH 0746/1971] ocfs2_dlm: Ensure correct ordering of set/clear
 refmap bit on lockres

Eventhough the set refmap bit message is sent before the clear refmap
message, currently there is no guarentee that the set message will be
handled before the clear. This patch prevents the clear refmap to be
processed while the node is sending assert master messages to other
nodes. (The set refmap message is sent as a response to the assert
master request).

Subject: [PATCH 0747/1971] ocfs2_dlm: disallow a domain join if node maps
 mismatch

There is a small window where a joining node may not see the node(s) that
just died but are still part of the domain. To fix this, we must disallow
join requests if the joining node has a different node map.

A new field node_map is added to dlm_query_join_request to send the current
nodes nodemap along with join request. On the receiving end the nodes that
are part of the cluster verifies if this new node sees all the nodes that
are still part of the cluster. They disallow the join if the maps mismatch.

Subject: [PATCH 0749/1971] ocfs2_dlm: Add timeout to dlm join domain

Currently the ocfs2 dlm has no timeout during dlm join domain. While this is
not a problem in normal operation, this does become an issue if, say, the
other node is refusing to let the node join the domain because of a stuck
recovery. This patch adds a 90 sec timeout.

Subject: [PATCH 0751/1971] ocfs2: introduce sc->sc_send_lock to protect
 outbound outbound messages

When there is a lot of multithreaded I/O usage, two threads can collide
while sending out a message to the other nodes. This is due to the lack of
locking between threads while sending out the messages.

When a connected TCP send(), sendto(), or sendmsg() arrives in the Linux
kernel, it eventually comes through tcp_sendmsg(). tcp_sendmsg() protects
itself by acquiring a lock at invocation by calling lock_sock().
tcp_sendmsg() then loops over the buffers in the iovec, allocating
associated sk_buff's and cache pages for use in the actual send. As it does
so, it pushes the data out to tcp for actual transmission. However, if one
of those allocation fails (because a large number of large sends is being
processed, for example), it must wait for memory to become available. It
does so by jumping to wait_for_sndbuf or wait_for_memory, both of which
eventually cause a call to sk_stream_wait_memory(). sk_stream_wait_memory()
contains a code path that calls sk_wait_event(). Finally, sk_wait_event()
contains the call to release_sock().

The following patch adds a lock to the socket container in order to
properly serialize outbound requests.

Subject: [PATCH 0752/1971] [PATCH] ocfs2 heartbeat: clean up bio submission
 code

As was already pointed out Mathieu Avila on Thu, 07 Sep 2006 03:15:25 -0700
that OCFS2 is expecting bio_add_page() to add pages to BIOs in an easily
predictable manner.

That is not true, especially for devices with own merge_bvec_fn().

Therefore OCFS2's heartbeat code is very likely to fail on such devices.

Move the bio_put() call into the bio's bi_end_io() function. This makes the
whole idea of trying to predict the behaviour of bio_add_page() unnecessary.
Removed compute_max_sectors() and o2hb_compute_request_limits().

Subject: [PATCH 0753/1971] configfs: Zero terminate data in configfs attribute
 writes.

Attributes in configfs are text files.  As such, most handlers expect to be
able to call functions like simple_strtoul() without checking the bounds
of the buffer.  Change the call to zero terminate the buffer before calling
the client's ->store() method.  This does reduce the attribute size from
PAGE_SIZE to PAGE_SIZE-1.

Also, change get_zeroed_page() to alloc_page(), as we are handling the
termination.

Subject: [PATCH 0760/1971] [PATCH] kbuild, Kbuild.include: avoid using spaces
 in call arguments

Do not use whitespace in arguments of functions in makefiles, as they
propagate further without notice.  Thus we get

  + echo ' y'

  instead of

  + echo y

Fix misleading comments.

Subject: [PATCH 0764/1971] USB: add EPIC support to the io_edgeport driver

This patch adds EPiC support to the io_edgeport driver which adds
support for a number of NCR printers:
	- NCR (Axiohm) 7401-K580 printer
	- NCR (TEC) 7401-K590 printer, 7402-K592
	- NCR (TEC) 7167, 7168 printers
	- NCR (TEC) 7197, 7198, F306, F307, F309 printers
	- NCR (Axiohm) 7194 printer
	- NCR (Axiohm) 7158 printer
and a few more.

It is based on the 2.6.19 kernel.

Subject: [PATCH 0767/1971] USB: Rework the OHCI quirk mecanism as suggested by
 David

This patch applies David Brownell's suggestion for reworking the
OHCI quirk mechanism via a table of PCI IDs. It adapts the existing
quirks to use that mechanism.

This also moves the quirks to reset() as suggested by the comment
in there. This is necessary as we need to have the endian properly
set before we try to init the controller.

Subject: [PATCH 0768/1971] USB: Implement support for "split" endian OHCI

This patch separates support for big endian MMIO register access
and big endian descriptors in order to support the Toshiba SCC
implementation which has big endian registers but little endian
in-memory descriptors.

It simplifies the access functions a bit in ohci.h while at it.

Subject: [PATCH 0769/1971] USB: Implement support for EHCI with big endian
 MMIO

This patch implements supports for EHCI controllers whose MMIO
registers are big endian and enables that functionality for
the Toshiba SCC chip. It does _not_ add support for big endian
in-memory data structures as this is not needed for that chip
and I hope it will never be.

The guts of the patch are to convert readl(...) to
ehci_readl(ehci, ...) and similarly for register writes.

Subject: [PATCH 0770/1971] USB: Fix OHCI warning

This patch fixes a warning introduces by the split endian OHCI support
patch on platforms that don't have readl_be/writel_be variants (though
mostly harmless as those are called in an if (0) statement, but gcc
still warns).

Subject: [PATCH 0779/1971] USB: ethernet gadget interop with MCCI Windows
 driver

It turns out that minor tweaks to the "CDC Subset" support in the Ethernet
gadget driver, just updating a config descriptor, let it be automagically
recognized by a Windows driver supported by MCCI.

This patch adds those descriptors, so systems using PXA 255 processors
(like Gumstix etc) can interop with those commercial MS-Windows drivers.
This is a Good Thing since Microsoft's RNDIS code has bugginess issues,
which are unfortunately compounded by "won't fix" issues as well as "the
published specs are incomplete and wrong" issues.  Being able to talk to
the MCCI driver gives Windows users another connectivity option.  (MCCI
also has CDC Ethernet drivers, which can help most non-PXA processors.)

Subject: [PATCH 0780/1971] rndis_host learns ActiveSync basics

Windows Mobile 5 based devices described as supporting "ActiveSync":

 - Speak RNDIS but lack the CDC and union descriptors.  This patch
   updates the cdc ethernet code to fake ACM descriptors we need.

 - Require RNDIS_MSG_QUERY messages to include a buffer of the size the
   response should generate.  This patch updates the rndis host code to
   pass this will-be-ignored data.

The resulting RNDIS host code has been reported to work with several
WM5 based devices.

(Note that a fancier patch is available at synce.sf.net.)


Some bugfixes, affecting not just ActiveSync:
    (a)	when cleaning up after RNDS init fails, scrub the second interface
	just like cdc_ether does, so disconnect won't oops.
    (b)	handle peripherals that use the pad-to-end-of-packet option; some
	devices can't talk to us if that option doesn't work.
    (c)	when choosing configurations, don't forget about an RNDIS config
	just because the RNDIS driver is dynamically linked.

Cleanup, streamlining, bugfixes, Kconfig, and matching hub driver update.
Also for paranoia's sake, refuse to talk to something that looks like a
real modem instead of RNDIS.

Subject: [PATCH 0781/1971] ohci: Rework bus glue integration to allow several
 at once

The previous model had the module_init & module_exit function in the
bus glue .c files themselves. That's a problem if several glues need
to be selected at once and the driver is built has module. This case
is quite common in embedded system where you want to handle both the
integrated ohci controller and some extra controller on PCI.

The ohci-hcd.c file now provide the module_init & module_exit and
appropriate driver registering/unregistering is done conditionally,
using #ifdefs.

Subject: [PATCH 0782/1971] ohci: Add support for OHCI controller on the
 of_platform bus

PPC embedded systems can have a ohci controller builtin. In the
new model, it will end up as a driver on the of_platform bus,
this patches takes care of them.

Subject: [PATCH 0783/1971] USB serial: add dynamic id support to usb-serial
 core
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Thanks to Johannes Hölzl <johannes.hoelzl@gmx.de> for fixing a few
things and getting it all working properly.

This adds support for dynamic usb ids to the usb serial core.  The file
"new_id" will show up under the usb serial driver, not the usb driver
associated with the usb-serial driver (yeah, it can be a bit confusing
at first glance...)

This patch also modifies the USB core to allow the usb-serial core to
reuse much of the dynamic id logic.

 drivers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every usb serial driver should have a pointer to the corresponding usb driver.
So the usb serial core can add a new id not only to the usb serial driver, but
also to the usb driver.

Also the usb drivers of ark3116, mos7720 and mos7840 missed the flag
no_dynamic_id=1. This is added now.

 usb_serial_driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While adding the dynamic-id support to usb serial I found a small bug in
the air cable driver:

Adds module and name information to the usb_serial_driver instance
of aircable. So the aircable driver is correctly shown under
/sys/bus/usb-serial/drivers/aircable and has the module link.

Subject: [PATCH 0788/1971] USB: add binary API to usbmon

This patch adds a new, "binary" API in addition to the old, text API usbmon
had before. The new API allows for less CPU use, and it allows to capture
all data from a packet where old API only captured 32 bytes at most. There
are some limitations and conditions to this, e.g. in case someone constructs
a URB with 1GB of data, it's not likely to be captured, because even the
huge buffers of the new reader are finite. Nonetheless, I expect this new
capability to capture all data for all real life scenarios.

The downside is, a special user mode application is required where cat(1)
worked before. I have sample code at http://people.redhat.com/zaitcev/linux/
and Paolo Abeni is working on patching libpcap.

This patch was initially written by Paolo and later I tweaked it, and
we had a little back-and-forth. So this is a jointly authored patch, but
I am submitting this I am responsible for the bugs.

 * Raw binary format and API
 
-TBD
+The overall architecture of the API is about the same as the one above,
+only the events are delivered in binary format. Each event is sent in
+the following structure (its name is made up, so that we can refer to it):
+
+struct usbmon_packet {
+	u64 id;			/*  0: URB ID - from submission to callback */
+	unsigned char type;	/*  8: Same as text; extensible. */
+	unsigned char xfer_type; /*    ISO (0), Intr, Control, Bulk (3) */
+	unsigned char epnum;	/*     Endpoint number and transfer direction */
+	unsigned char devnum;	/*     Device address */
+	u16 busnum;		/* 12: Bus number */
+	char flag_setup;	/* 14: Same as text */
+	char flag_data;		/* 15: Same as text; Binary zero is OK. */
+	s64 ts_sec;		/* 16: gettimeofday */
+	s32 ts_usec;		/* 24: gettimeofday */
+	int status;		/* 28: */
+	unsigned int length;	/* 32: Length of data (submitted or actual) */
+	unsigned int len_cap;	/* 36: Delivered length */
+	unsigned char setup[8];	/* 40: Only for Control 'S' */
+};				/* 48 bytes total */
+
+These events can be received from a character device by reading with read(2),
+with an ioctl(2), or by accessing the buffer with mmap.
+
+The character device is usually called /dev/usbmonN, where N is the USB bus
+number. Number zero (/dev/usbmon0) is special and means "all buses".
+However, this feature is not implemented yet. Note that specific naming
+policy is set by your Linux distribution.
+
+If you create /dev/usbmon0 by hand, make sure that it is owned by root
+and has mode 0600. Otherwise, unpriviledged users will be able to snoop
+keyboard traffic.
+
+The following ioctl calls are available, with MON_IOC_MAGIC 0x92:
+
+ MON_IOCQ_URB_LEN, defined as _IO(MON_IOC_MAGIC, 1)
+
+This call returns the length of data in the next event. Note that majority of
+events contain no data, so if this call returns zero, it does not mean that
+no events are available.
+
+ MON_IOCG_STATS, defined as _IOR(MON_IOC_MAGIC, 3, struct mon_bin_stats)
+
+The argument is a pointer to the following structure:
+
+struct mon_bin_stats {
+	u32 queued;
+	u32 dropped;
+};
+
+The member "queued" refers to the number of events currently queued in the
+buffer (and not to the number of events processed since the last reset).
+
+The member "dropped" is the number of events lost since the last call
+to MON_IOCG_STATS.
+
+ MON_IOCT_RING_SIZE, defined as _IO(MON_IOC_MAGIC, 4)
+
+This call sets the buffer size. The argument is the size in bytes.
+The size may be rounded down to the next chunk (or page). If the requested
+size is out of [unspecified] bounds for this kernel, the call fails with
+-EINVAL.
+
+ MON_IOCQ_RING_SIZE, defined as _IO(MON_IOC_MAGIC, 5)
+
+This call returns the current size of the buffer in bytes.
+
+ MON_IOCX_GET, defined as _IOW(MON_IOC_MAGIC, 6, struct mon_get_arg)
+
+This call waits for events to arrive if none were in the kernel buffer,
+then returns the first event. Its argument is a pointer to the following
+structure:
+
+struct mon_get_arg {
+	struct usbmon_packet *hdr;
+	void *data;
+	size_t alloc;		/* Length of data (can be zero) */
+};
+
+Before the call, hdr, data, and alloc should be filled. Upon return, the area
+pointed by hdr contains the next event structure, and the data buffer contains
+the data, if any. The event is removed from the kernel buffer.
+
+ MON_IOCX_MFETCH, defined as _IOWR(MON_IOC_MAGIC, 7, struct mon_mfetch_arg)
+
+This ioctl is primarily used when the application accesses the buffer
+with mmap(2). Its argument is a pointer to the following structure:
+
+struct mon_mfetch_arg {
+	uint32_t *offvec;	/* Vector of events fetched */
+	uint32_t nfetch;	/* Number of events to fetch (out: fetched) */
+	uint32_t nflush;	/* Number of events to flush */
+};
+
+The ioctl operates in 3 stages.
+
+First, it removes and discards up to nflush events from the kernel buffer.
+The actual number of events discarded is returned in nflush.
+
+Second, it waits for an event to be present in the buffer, unless the pseudo-
+device is open with O_NONBLOCK.
+
+Third, it extracts up to nfetch offsets into the mmap buffer, and stores
+them into the offvec. The actual number of event offsets is stored into
+the nfetch.
+
+ MON_IOCH_MFLUSH, defined as _IO(MON_IOC_MAGIC, 8)
+
+This call removes a number of events from the kernel buffer. Its argument
+is the number of events to remove. If the buffer contains fewer events
+than requested, all events present are removed, and no error is reported.
+This works when no events are available too.
+
+ FIONBIO
+
+The ioctl FIONBIO may be implemented in the future, if there's a need.
+
+In addition to ioctl(2) and read(2), the special file of binary API can
+be polled with select(2) and poll(2). But lseek(2) does not work.
+
+* Memory-mapped access of the kernel buffer for the binary API
+
+The basic idea is simple:
+
+To prepare, map the buffer by getting the current size, then using mmap(2).
+Then, execute a loop similar to the one written in pseudo-code below:
+
+   struct mon_mfetch_arg fetch;
+   struct usbmon_packet *hdr;
+   int nflush = 0;
+   for (;;) {
+      fetch.offvec = vec; // Has N 32-bit words
+      fetch.nfetch = N;   // Or less than N
+      fetch.nflush = nflush;
+      ioctl(fd, MON_IOCX_MFETCH, &fetch);   // Process errors, too
+      nflush = fetch.nfetch;       // This many packets to flush when done
+      for (i = 0; i < nflush; i++) {
+         hdr = (struct ubsmon_packet *) &mmap_area[vec[i]];
+         if (hdr->type == '@')     // Filler packet
+            continue;
+         caddr_t data = &mmap_area[vec[i]] + 64;
+         process_packet(hdr, data);
+      }
+   }
+
+Thus, the main idea is to execute only one ioctl per N events.
+
+Although the buffer is circular, the returned headers and data do not cross
+the end of the buffer, so the above pseudo-code does not need any gathering.

Date: Mon, 8 Jan 2007 12:00:28 -0500
Subject: [PATCH 0790/1971] UHCI: improved debugging checks for the frame list

This patch (as768) improves the debugging checks for the uhci-hcd
frame list.  The number of entries displayed is limited to 10, and the
driver now checks for the correct Skeleton QH link value at the end of
each chain of Isochronous TDs.  The code to compute these link values
is now used in two spots, so it is moved into its own separate
subroutine.

Subject: [PATCH 0791/1971] UHCI: no dummy TDs for Iso QHs

Isochronous queues don't need a dummy TD because the Queue Header
isn't managed by the hardware.  This patch (as836) removes the
unnecessary dummy TDs.

The patch also fixes a long-standing typo in a comment (a "don't" was
missing -- potentially very confusing!).

Subject: [PATCH 0792/1971] usb-storage: SCSI level fixes

This patch (as835) removes from usb-storage the code which sets all
devices to a SCSI level of at least SCSI-2.  The original reasons for
doing this no longer apply, and in fact it prevents certain kinds of
ATA pass-thru commands from being used.

The patch also marks CB and CBI devices that are SCSI-0 (legacy SCSI)
as being single-LUN, since the combined SCSI-over-USB transport
protocol has no way to convey LUN information to these devices.

Subject: [PATCH 0793/1971] USB: ohci-at91 refcount fix for irq wake enables

The attached patch fixes the unbalanced calls to enable_irq_wake() and
disable_irq_wake() in the AT91 USB Host driver.

It should resolve these kernel messages:
  Unbalanced IRQ x wake disable
  BUG: warning at kernel/irq/manage.c:167/set_irq_wake()

(The original code was debugged before a bug in the genirq wakeup irq
logic was fixed by adding the IRQ wake enable/disable refcounting.
Not all code yet uses the bugfixed model.)

Subject: [PATCH 0795/1971] usb: gadgetfs remove delayed init mode

Gadgetfs had a mode in which endpoint descriptors were written by the user
program before connection.  This mode had some bugs, and hasn't seen much
(if any) use.  This patch removes that mode, leaving the mode of operation
where the user program waits for endpoint 0 to report a SET_CONFIGURATION,
and only then configures the endpoints.

From 896fbd7199035958013d106329843d8ae9618753 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0803/1971] usbcore: remove unused bandwith-related code

This patch (as841) removes from usbcore a couple of support routines
meant to help with bandwidth allocation.  With the changes to uhci-hcd
in the previous patch, these routines are no longer used anywhere.
Also removed is the CONFIG_USB_BANDWIDTH option; it no longer does
anything and is no longer needed since the HCDs now handle bandwidth
issues correctly.

Subject: [PATCH 0804/1971] EHCI: local variable for port status register

This patch (as708) introduces a local variable to hold the port
status-register address in ehci-hub.c.  There's not much improvement
in the object code, but it sure is a lot easier to read.

hides the information; in particular, it allows the core to see the
disconnect event that occurs when a full- or low-speed device is
switched over to the companion.  This is required for the next patch
in this series.

Subject: [PATCH 0806/1971] EHCI: force high-speed devices to run at full speed

This patch (as710) adds a sysfs class-device attribute file named
"companion" for EHCI controllers.  The file contains a list of port
numbers that are dedicated to the companion controller; by writing a
port number to the file the user can force a high-speed device
attached directly to the computer to run at full speed.  (As far as I
know it is not possible to do this for a device attached to an
external hub.)  A port is removed from the file by writing the
negative of its port number.

Several users have asked for this facility and it seems like a useful
thing to have.  Every now and then one runs across a device which
behaves much better at full speed than at high speed.

Subject: [PATCH 0807/1971] USB: at91_udc wakeup event updates

This updates the AT91 UDC driver's handling of wakeup events:

 - Fix a bug in the original scheme, which was never updated after
   the {enable,disable}_irq_wake() semantics were updated to address
   refcounting issues (i.e. behave for shared irqs).

 - Couple handling of both type of wakeup events, to be more direct.  The
   controller can be source of wakeup events for cases like bus reset
   and USB resume.  On some boards, VBUS sensing is also IRQ driven.

The whole approach is simply wrong.  Forking a thread means that
  - errors are ignored
  - locking is ignored

Doing this correctly would require major surgery for questionable benefit.

Subject: [PATCH 0809/1971] fix for bugzilla #7544 (keyspan USB-to-serial
 converter)

At least the Keyspan USA-19HS USB-to-serial converter supports
two different configurations, one where the input endpoints
have interrupt transfer type and one where they are bulk endpoints.
The default UHCI configuration uses the interrupt input endpoints.
The keyspan driver, OTOH, assumes that the device has only bulk
endpoints (all URBs are initialized by calling usb_fill_bulk_urb
in keyspan.c/ keyspan_setup_urb). This causes the interval field
of the input URBs to have a value of zero instead of one, which
'accidentally' worked with Linux at least up to 2.6.17.11 but
stopped to with 2.6.18, which changed the UHCI support code handling
URBs for interrupt endpoints. The patch below modifies to driver to
initialize its input URBs either as interrupt or as bulk URBs,
depending on the transfertype contained in the associated endpoint
descriptor (only tested with the default configuration) enabling
the driver to again receive data from the serial converter.

Greg K-H reworked the patch.

Subject: [PATCH 0810/1971] USB: race fixes for usb-serial step 1

- introduce a spinlock for serial_table to eliminate the window between
  looking up a device and getting a reference
- delay inscription of a new device into serial_table until it is fully
  initialised
- make sure disconnect() kills all URBs to avoid leckage across a soft unbind

Subject: [PATCH 0813/1971] USB: gadgetfs cleanups

Minor gadgetfs cleanups:

 - EP0 state constants become consistently STATE_DEV_* rather than
   sometimes omitting the "DEV_"; STATE_EP_* were already consistent.

 - Comment that ep0 state is protected by the spinlock, and update
   code that was neglecting that rule.

None of this is expected to change behavior.

Subject: [PATCH 0814/1971] USB: gadgetfs simplifications

This simplifies event reading by eliminating arithmetic and being
more direct/obvious, and tweaks some debug messages slightly.
The math elimination will change timings, sometimes enough to
allow a race to appear.

Subject: [PATCH 0815/1971] USB: gadgetfs race fix

This resolves a race in gadgetfs associated with changing device/ep0
when processing control requests.  The fix is to change that state
earlier, when the control response is issued, so there's no window
in which userspace could see the wrong state; and enlarge the scope
of the spinlock during the ep0 request completion handler.

Subject: [PATCH 0817/1971] USB: gadgetfs AIO tweaks

This patch (as837) fixes several mistakes in the AIO interface of the
gadgetfs driver:

	The ki_retry method is not supposed to do a put on the kiocb.
	The extra call to aio_put_req() causes memory corruption.
	(Note: This call was removed before, by patch as691, and then
	mysteriously re-introduced later.)

	Even if a read transfer is cancelled, we can and should send
	to the user all the data that did manage to get transferred.

	Testing for AIO cancellation in the I/O completion handler
	is both racy and (now) unnecessary.  aio_complete() does its
	own checking, in a safe manner.

Subject: [PATCH 0823/1971] USB: switch ehci-hcd to new polling scheme

Switch ehci-hcd to use the new polling scheme, which reports root
hub status changes via the interrupt handler, in an asynchronous
fashion. Doing so disables polling for status changes (whose handler is
rh_timer_func).

Tested on a Geode GX machine, which is now capable of running at =~ 5
timer interrupts per second (in the -rt tree), resulting in significant
power savings.

Subject: [PATCH 0824/1971] EHCI: fix interrupt-driven remote wakeup

Now that port status change notifications are interrupt-driven,
ehci-hcd needs to tell usbcore when a remote-wakeup resume operation
is finished -- we can no longer rely on the core to poll and find
out.  This patch (as843) uses the root-hub status timer to force a
poll after the resume is complete.

The patch also changes the test for detecting when the TDRSMDN resume
period has expired.  It's necessary to use time_after_eq() instead of
time_after(), since the polling is triggered precisely by a timer.
The same change is made for TDRSTR reset expiration, for consistency.

Subject: [PATCH 0825/1971] usb-storage: use first bulk endpoints, not last

According to the Bulk-Only spec, usb-storage is supposed to use the
_first_ bulk-in and bulk-out endpoints it finds, not the _last_.  And
while we're at it, we ought to test the direction of the interrupt
endpoint as well.  This patch (as842) makes both changes.

Subject: [PATCH 0835/1971] z85230: spinlock logic

At some point someone added a spin_lock(&dev->lock) to the IRQ handler for
the Z85230 driver.  This actually correctly fixes a bug but the necessary
changes to remove the chan->lock calls in the event handlers were not made
(c->lock is the same lock).

Simona Dascenzo reported the problem with the driver and this patch should
fix the problem he found.

From 07eddf3d597f2d009a37a4e8c7c32a1ffe992f3e Mon Sep 17 00:00:00 2001
From: Yinghai Lu <yinghai.lu@amd.com>
Date: Wed, 29 Nov 2006 13:53:10 -0800
Subject: [PATCH 0839/1971] PCI: check szhi when sz is 0 when 64 bit iomem
 bigger than 4G

For pci mem resource that size is bigger than 4G, the sz returned by
pc_size will be 0.
So that resource is skipped, and register contained hi address will be
treated as another 32bit resource. We need to use sz64 and pci_sz64 for
64 bit resource for clear logical.  Typical usages for this: Opteron
system with co-processor and the co-processor could take more than 4G
RAM as pre-fetchable mem resource.

Subject: [PATCH 0840/1971] PCI : remove too specialized __pci_enable_device
 for default resume

Original patch was posted as "PCI : Move pci_fixup_device and is_enabled".
This 1 of 3 patches does:

  - reverts small part of Inaky's patch
    (remove __pci_enable_device)
    This change will be recovered by 3rd patch.

  - temporarily remove pci_fixup_device.
    This change will be recovered by 2nd patch.

Subject: [PATCH 0843/1971] PCI : Add selected_regions funcs

This patch adds the following changes into generic PCI code especially
for PCI legacy I/O port free drivers.

     - Added new pci_request_selected_regions() and
       pci_release_selected_regions() for PCI legacy I/O port free
       drivers in order to request/release only the selected regions.

     - Added helper routine pci_select_bars() which makes proper mask
       of BARs from the specified resource type. This would be very
       helpful for users of pci_enable_device_bars().

So let's mark it as __deprecated now, which also has the side effect
that noone can later whine that removing it might break some shiny
external modules.

Oh, and if anything starts complaining "But this adds some warnings to
my kernel build!", he should either first fix the 200 kB (sic) of
warnings I'm getting in 2.6.19-rc5-mm2 starting at MODPOST or go to hell.

Subject: [PATCH 0857/1971] pciehp: fix wait command completion

This patch fixes this problem that pciehp driver will sleep
unnecessarily long when waiting for command completion. With this
patch, modprobe pciehp driver becomes very faster as follows for
instance.

  o Without this patch
    # time /sbin/modprobe pciehp

    real    0m4.976s
    user    0m0.000s
    sys     0m0.004s

  o With this patch
    # time /sbin/modprobe pciehp

    real    0m0.640s
    user    0m0.000s
    sys     0m0.004s

 CONFIG_HOTPLUG_PCI_SHPC_POLL_EVENT_MODE

The CONFIG_HOTPLUG_PCI_SHPC_POLL_EVENT_MODE config option is not
needed because polling mechanism for shpc hotplug events can be
enabled through module option 'shpchp_poll_mode'. This patch removes
CONFIG_HOTPLUG_PCI_SHPC_POLL_EVENT_MODE.

Subject: [PATCH 0862/1971] PCI Quirk: 1k I/O space IOBL_ADR fix on P64H2

There's an existing quirk for the kernel to use 1k IO space granularity
on the Intel P64H2.  It turns out however that pci_setup_bridge() in
drivers/pci/setup-bus.c reads in the IO base and limit address register
masks it off to the nearest 4k, and writes it back.  This causes the
kernel to be on 1k boundaries and the hardware to be 4k aligned.  The
patch below fixes the problem.

Subject: [PATCH 0863/1971] PCI: Speed up the Intel SMBus unhiding quirk

Speed up the Intel SMBus PCI quirk by avoiding tests which can only
fail. This also makes the compiled code significantly smaller when
using gcc 3.2/3.4. gcc 4.x appears to optimize the code by itself so
this change doesn't make a difference there.

Subject: [PATCH 0870/1971] MSI: Replace pci_msi_quirk with calls to
 pci_no_msi()

I don't see any reason why we need pci_msi_quirk, quirk code can just
call pci_no_msi() instead.

Remove the check of pci_msi_quirk in msi_init(). This is safe as all
calls to msi_init() are protected by calls to pci_msi_supported(),
which checks pci_msi_enable, which is disabled by pci_no_msi().

The pci_disable_msi routines didn't check pci_msi_quirk, only
pci_msi_enable, but as far as I can see that was a bug not a feature.

Subject: [PATCH 0872/1971] MSI: Combine pci_(save|restore)_msi/msix_state

The PCI save/restore code doesn't need to care about MSI vs MSI-X, all
it really wants is to say "save/restore all MSI(-X) info for this device".

This is borne out in the code, we call the MSI and MSI-X save routines
side by side, and similarly with the restore routines.

So combine the MSI/MSI-X routines into pci_save_msi_state() and
pci_restore_msi_state(). It is up to those routines to decide what state
needs to be saved.

Subject: [PATCH 0873/1971] msi: Kill msi_lookup_irq

The function msi_lookup_irq was horrible.  As a side effect of running
it changed dev->irq, and then the callers would need to change it
back.  In addition it does a global scan through all of the irqs,
which seems to be the sole justification of the msi_lock.

To remove the neede for msi_lookup_irq I added first_msi_irq to struct
pci_dev.  Then depending on the context I replaced msi_lookup_irq with
dev->first_msi_irq, dev->msi_enabled, or dev->msix_enabled.

msi_enabled and msix_enabled were already present in pci_dev for other
reasons.

Subject: [PATCH 0874/1971] msi: Remove msi_lock.

With the removal of msi_lookup_irq all of the functions using msi_lock
operated on a single device and none of them could reasonably be
called on that device at the same time.

Since what little synchronization that needs to happen needs to happen
outside of the msi functions, msi_lock could never be contended and as
such is useless and just complicates the code.

Subject: [PATCH 0875/1971] msi: Fix msi_remove_pci_irq_vectors.

Since msi_remove_pci_irq_vectors is designed to be called during
hotplug remove it is actively wrong to query the hardware and expect
meaningful results back.

To that end remove the pci_find_capability calls.  Testing
dev->msi_enabled and dev->msix_enabled gives us all of the information
we need.

Subject: [PATCH 0877/1971] msi: Kill the msi_desc array.

We need to be able to get from an irq number to a struct msi_desc.
The msi_desc array in msi.c had several short comings the big one was
that it could not be used outside of msi.c.  Using irq_data in struct
irq_desc almost worked except on some architectures irq_data needs to
be used for something else.

So this patch adds a msi_desc pointer to irq_desc, adds the appropriate
wrappers and changes all of the msi code to use them.

The dynamic_irq_init/cleanup code was tweaked to ensure the new
field is left in a well defined state.

From f7feaca77d6ad6bcfcc88ac54e3188970448d6fe Mon Sep 17 00:00:00 2001

Subject: [PATCH 0878/1971] msi: Make MSI useable more architectures

The arch hooks arch_setup_msi_irq and arch_teardown_msi_irq are now
responsible for allocating and freeing the linux irq in addition to
setting up the the linux irq to work with the interrupt.

arch_setup_msi_irq now takes a pci_device and a msi_desc and returns
an irq.

With this change in place this code should be useable by all platforms
except those that won't let the OS touch the hardware like ppc RTAS.

Subject: [PATCH 0879/1971] sky2: use dev_err for error reports

Use the standard dev_xxx functions instead of printk directly for
error reports. Fix a bug where the initialization would return 0
if allocation of network device failed.

The Yukon EC_U chipset apparently supports TSO but only for non-Jumbo
frame sizes because it lacks a Ram buffer.

Rather than trying to be "smart" about possible transmit timeout
causes. Just clear all pending frames and reset the PHY.

Subject: [PATCH 0882/1971] sky2: Yukon Extreme support

This is basic support for the new Yukon Extreme
chip, extracted from the new vendor driver 10.0.4.3.

Since this is untested hardware, it has a big fat warning for now.

Subject: [PATCH 0885/1971] AT91: MACB support

The Atmel MACB Ethernet peripheral is also integrated in the AT91SAM9260
and AT91SAM9263 processors.  The differences from the AVR32 version are:
      * Single peripheral clock.
      * MII/RMII selection bit is inverted.
      * Clock enable bit.

Original patch from Patrice Vilchez.

From 1d58420bad15d08f93bf1e0342c1b1d1234d69b7 Mon Sep 17 00:00:00 2001
From: Thomas Hellstrom <thomas-at-tungstengraphics-dot-com>
Date: Mon, 8 Jan 2007 22:25:47 +1100
Subject: [PATCH 0894/1971] drm: update core memory manager from git drm tree

Remove the memory manager parameter from the put_block function, as this
makes the client code a lot cleaner. Prepare buffer manager for lock and
unlock calls.
Fix buggy aligned allocations.
Remove the stupid root_node field from the core memory manager.
Support multi-page buffer offset alignments
Add improved alignment functionality to the core memory manager.
This makes an allocated block actually align itself and returns any
wasted space to the manager.

Subject: [PATCH 0896/1971] [POWERPC] Only use H_BULK_REMOVE if the firmware
 supports it

The previous patch changing pSeries to use H_BULK_REMOVE broke the
JS20 blade, where the firmware doesn't support H_BULK_REMOVE.  This
adds a firmware check so that on machines that don't have H_BULK_REMOVE,
we just use the H_REMOVE call as before.

Subject: [PATCH 0897/1971] kbuild: make $(checker-shell ) strip spaces around
 the result

It looks like GNU make version 3.80 (but apparently not 3.81) adds
leading whitespace to the result of the checker-shell execution.  This
strips them off explicitly.

Also, don't bother symlinking the output file to /dev/null.  It's likely
as expensive as just writing the temp-file, and we need to remove it
anyway afterwards.

Subject: [PATCH 0905/1971] [POWERPC] Fix comment in kernel/irq.c

kernel/irq.c contains a comment that speaks of -1 and -2 as interrupt
numbers, but this is actually dependent on configuration options now.
Replace by NO_IRQ and NO_IRQ_ENABLED.

When the windfarm thread gets a suspend signal it will die instead of
freezing. This fixes it.

is used by drivers/video/console/vgacon.c which can be compiled as a module
(drivers/video/vga16fb.ko).

Therefore, vgacon_remap_base should be exported.

Subject: [PATCH 0910/1971] Revert "Driver core: convert SPI code to use struct
 device"

This reverts commit 2943ecf2ed32632473c06f1975db47a7aa98c10f.

This should go through the SPI maintainer, it was my fault that it did
not.  Especially as it conflicts with other patches he has pending.

Subject: [PATCH 0913/1971] ieee1394: modified csr1212_key_id_type_map to
 support lisight

This patch applies a little change in csr1212.c to fix iSight (firewire
digital camera) related issues (but maybe other firewire devices could
also need such modification)
The actual implementation of the "csr1212_key_id_type_map" table doesn't
support some node types used by the iSight for the audio unit. This
limit makes the csr scanning routine to never see the audio unit node ,
and consequently the iSight driver probe() routine to be never called
and there is no way to hook an isight device when it is inserted.

Subject: [PATCH 0918/1971] ieee1394: nodemgr: check info_length in ROM header
 earlier

The whole ROM area which is covered by the crc_length field of the ROM
header was fetched before the info_length field was checked for correct
general ROM format.  This might be wasteful or even dangerous with nodes
with minimal ROM, nonstandard ROM, or corrupt ROM.

Perform this check at the earliest opportunity.

Subject: [PATCH 0923/1971] ieee1394: sbp2: lower block queue alignment
 requirement

The old setting is copy & waste from usb-storage and doesn't apply to
sbp2.  There is only 4-byte alignment required for everything, except
for S/G table elements which have to be 8-byte aligned according to the
SBP-2 spec.  (They happen to be ____cacheline_aligned in our
implementation.  Whether that's good is another question.)

We now simply don't tune block queue alignment at all.  The default
alignment would surely never become anything else than a multiple of 4,
else tons of calls to blk_queue_dma_alignment would have to be added
everywhere in drivers/...

Subject: [PATCH 0926/1971] ieee1394: raw1394: prevent unloading of low-level
 driver

Unloading the low-level driver module of a FireWire host can lead to
all sorts of trouble if a raw1394 userspace client is using the host.
Just disallow it by incrementing the LLD's module reference count on
a RAW1394_REQ_SET_CARD write operation.  Decrement it when the file
is closed.

This feature wouldn't be relevant if "modprobe -r video1394" or
"modprobe -r dv1394" didn't automatically unload ohci1394 too.

Subject: [PATCH 0928/1971] ieee1394: fix host device registering when nodemgr
 disabled

Since my commit 8252bbb1363b7fe963a3eb6f8a36da619a6f5a65 in 2.6.20-rc1,
host devices have a dummy driver attached.  Alas the driver was not
registered before use if ieee1394 was loaded with disable_nodemgr=1.

This resulted in non-functional FireWire drivers or kernel lockup.

Subject: [PATCH 0930/1971] [NETLINK]: Don't BUG on undersized allocations

Currently netlink users BUG when the allocated skb for an event
notification is undersized. While this is certainly a kernel bug,
its not critical and crashing the kernel is too drastic, especially
when considering that these errors have appeared multiple times in
the past and it BUGs even if no listeners are present.

This patch replaces BUG by WARN_ON and changes the notification
functions to inform potential listeners of undersized allocations
using a unique error code (EMSGSIZE).

Subject: [PATCH 0932/1971] [TCP]: remove tcp header from tcp_v4_check (take
 #2)

The tcphdr struct passed to tcp_v4_check is not used, the following
patch removes it from the parameter list.

This adds the netfilter modifications missing in the patch I sent
for rc3-mm1.

From: "David S. Miller" <davem@sunset.davemloft.net>

Subject: [PATCH 0933/1971] [IPV4/IPV6]: Always wait for IPSEC SA resolution in
 socket contexts.

Do this even for non-blocking sockets.  This avoids the silly -EAGAIN
that applications can see now, even for non-blocking sockets in some
cases (f.e. connect()).

With help from Venkat Tekkirala.

From 8dc4194474159660d7f37c495e3fc3f10d0db8cc Mon Sep 17 00:00:00 2001

Subject: [PATCH 0934/1971] [PACKET]: Add optional checksum computation for
 recvmsg

This patch is needed to make ISC's DHCP server (and probably other
DHCP servers/clients using AF_PACKET) to be able to serve another
client on the same Xen host.

The problem is that packets between different domains on the same
Xen host only have partial checksums.  Unfortunately this piece of
information is not passed along in AF_PACKET unless you're using
the mmap interface.  Since dhcpd doesn't support packet-mmap, UDP
packets from the same host come out with apparently bogus checksums.

This patch adds a mechanism for AF_PACKET recvmsg(2) to return the
status along with the packet.  It does so by adding a new cmsg that
contains this information along with some other relevant data such
as the original packet length.

I didn't include the time stamp information since there is already
a cmsg for that.

This patch also changes the mmap code to set the CSUMNOTREADY flag
on all packets instead of just outoing packets on cooked sockets.

Subject: [PATCH 0935/1971] [PACKET]: Fix skb->cb clobbering between aux and
 sockaddr

Both aux data and sockaddr tries to use the same buffer which
obviously doesn't work.  We just happen to have 4 bytes free in
the skb->cb if you take away the maximum length of sockaddr_ll.
That's just enough to store the one piece of info from aux data
that we can't generate at recvmsg(2) time.

This is what the following patch does.

Subject: [PATCH 0937/1971] [TCP]: Seperate DSACK from SACK fast path

Move DSACK code outside the SACK fast-path checking code. If the DSACK
determined that the information was too old we stayed with a partial cache
copied. Most likely this matters very little since the next packet will not be
DSACK and we will find it in the cache. but it's still not good form and there
is little reason to couple the two checks.

Since the SACK receive cache doesn't need the data to be in host order we also
remove the ntohl in the checking loop.

Subject: [PATCH 0938/1971] [TCP]: Check num sacks in SACK fast path

We clear the unused parts of the SACK cache, This prevents us from mistakenly
taking the cache data if the old data in the SACK cache is the same as the data
in the SACK block. This assumes that we never receive an empty SACK block with
start and end both at zero.

Subject: [PATCH 0940/1971] [NET]: user of the jiffies rounding code:
 Networking

This patch introduces users of the round_jiffies() function in the
networking code.

These timers all were of the "about once a second" or "about once
every X seconds" variety and several showed up in the "what wakes the
cpu up" profiles that the tickless patches provide.  Some timers are
highly dynamic based on network load; but even on low activity systems
they still show up so the rounding is done only in cases of low
activity, allowing higher frequency timers in the high activity case.

The various hardware watchdogs are an obvious case; they run every 2
seconds but aren't otherwise specific of exactly when they need to
run.

Subject: [PATCH 0941/1971] [ATM]: Fix for crash in adummy_init()

This was reported by Ingo Molnar here,

http://lkml.org/lkml/2006/12/18/119

The problem is that adummy_init() depends on atm_init() , but adummy_init()
is called first.

So I put atm_init() into subsys_initcall which seems appropriate, and it
will still get module_init() if it becomes a module.

Interesting to note that you could crash your system here if you just load
the modules in the wrong order.

Subject: [PATCH 0945/1971] [TG3]: Avoid an expensive divide.

During an oprofile session of linux-2.6.20 on a dual opteron system, I noticed
an expensive divide was done in tg3_poll().

I am using gcc-4.1.1, so the following comment from drivers/net/tg3.c seems
over-optimistic :

/* Do not place this n-ring entries value into the tp struct itself,
  * we really want to expose these constants to GCC so that modulo et
  * al.  operations are done with shifts and masks instead of with
  * hw multiply/modulo instructions.  Another solution would be to
  * replace things like '% foo' with '& (foo - 1)'.
  */
#define TG3_RX_RCB_RING_SIZE(tp)        \
         ((tp->tg3_flags2 & TG3_FLG2_5705_PLUS) ?  512 : 1024)

Assembly code before patch :

Subject: [PATCH 0950/1971] [XFRM]: Fix missed error setting in xfrm4_policy.c

When we can't find the afinfo we should return EAFNOSUPPORT.
GCC warned about the uninitialized 'err' for this path as well.

Subject: [PATCH 0952/1971] [IPV6] RAW: Add checksum default defines for MH.

Add checksum default defines for mobility header(MH) which
goes through raw socket. As the result kernel's behavior is
to handle MH checksum as default.

This patch also removes verifying inbound MH checksum at
mip6_mh_filter() since it did not consider user specified
checksum offset and was redundant check with raw socket code.

Subject: [PATCH 0956/1971] [NETFILTER]: Add SANE connection tracking helper

This is nf_conntrack_sane, a netfilter connection tracking helper module
for the SANE protocol used by the 'saned' daemon to make scanners available
via network. The SANE protocol uses separate control & data connections,
similar to passive FTP. The helper module is needed to recognize the data
connection as RELATED to the control one.

Subject: [PATCH 0957/1971] [NETFILTER]: tcp conntrack: do liberal tracking for
 picked up connections

Do liberal tracking (only RSTs need to be in-window) for connections picked
up without seeing a SYN to deal with window scaling. Also change logging
of invalid packets not to log packets accepted by liberal tracking to avoid
spamming the logs.

Based on suggestion from James Ralston <ralston@pobox.com>

Subject: [PATCH 0970/1971] [XFRM]: Extension for dynamic update of endpoint
 address(es)

Extend the XFRM framework so that endpoint address(es) in the XFRM
databases could be dynamically updated according to a request (MIGRATE
message) from user application. Target XFRM policy is first identified
by the selector in the MIGRATE message. Next, the endpoint addresses
of the matching templates and XFRM states are updated according to
the MIGRATE message.

Subject: [PATCH 0973/1971] [PFKEYV2]: Extension for dynamic update of endpoint
 address(es)

Extend PF_KEYv2 framework so that user application can take advantage
of MIGRATE feature via PF_KEYv2 interface. User application can either
send or receive an MIGRATE message to/from PF_KEY socket.

Detail information can be found in the internet-draft
<draft-sugimoto-mip6-pfkey-migrate>.

Subject: [PATCH 0976/1971] [X.25]: Add call forwarding

Adds call forwarding to X.25, allowing it to operate like an X.25 router.
Useful if one needs to manipulate X.25 traffic with tools like tc.
This is an update/cleanup based off a patch submitted by Daniel Ferenci a few years ago.

Thanks Alan for the feedback.
Added the null check to the clones.
Moved the skb_clone's into the forwarding functions.

Worked ok with Cisco XoT, linux X.25 back to back, and some old NTUs/PADs.

From dbca9b2750e3b1ee6f56a616160ccfc12e8b161f Mon Sep 17 00:00:00 2001

Subject: [PATCH 0986/1971] [NET]: change layout of ehash table

ehash table layout is currently this one :

First half of this table is used by sockets not in TIME_WAIT state
Second half of it is used by sockets in TIME_WAIT state.

This is non optimal because of for a given hash or socket, the two chain heads
are located in separate cache lines.
Moreover the locks of the second half are never used.

If instead of this halving, we use two list heads in inet_ehash_bucket instead
of only one, we probably can avoid one cache miss, and reduce ram usage,
particularly if sizeof(rwlock_t) is big (various CONFIG_DEBUG_SPINLOCK,
CONFIG_DEBUG_LOCK_ALLOC settings). So we still halves the table but we keep
together related chains to speedup lookups and socket state change.

In this patch I did not try to align struct inet_ehash_bucket, but a future
patch could try to make this structure have a convenient size (a power of two
or a multiple of L1_CACHE_SIZE).
I guess rwlock will just vanish as soon as RCU is plugged into ehash :) , so
maybe we dont need to scratch our heads to align the bucket...

Note : In case struct inet_ehash_bucket is not a power of two, we could
probably change alloc_large_system_hash() (in case it use __get_free_pages())
to free the unused space. It currently allocates a big zone, but the last
quarter of it could be freed. Again, this should be a temporary 'problem'.

Patch tested on ipv4 tcp only, but should be OK for IPV6 and DCCP.

Subject: [PATCH 0987/1971] [NET]: cleanup sock_from_file()

I believe dead code from sock_from_file() can be cleaned up.

All sockets are now built using sock_attach_fd(), that puts the 'sock' pointer
into file->private_data and &socket_file_ops into file->f_op

I could not find a place where file->private_data could be set to NULL,
keeping opened the file.

So to get 'sock' from a 'file' pointer, either :

- This is a socket file (f_op == &socket_file_ops), and we can directly get
'sock' from private_data.
- This is not a socket, we return -ENOTSOCK and dont even try to find a socket
via dentry/inode :)

Subject: [PATCH 0988/1971] [NET]: Fix net/socket.c warnings.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GCC (correctly) says:

net/socket.c: In function ‘sys_sendto’:
net/socket.c:1510: warning: ‘err’ may be used uninitialized in this function
net/socket.c: In function ‘sys_recvfrom’:
net/socket.c:1571: warning: ‘err’ may be used uninitialized in this function

sock_from_file() either returns filp->private_data or it
sets *err and returns NULL.

Callers return "err" on NULL, but filp->private_data could
be NULL.

Some minor rearrangements of error handling in sys_sendto
and sys_recvfrom solves the issue.

Subject: [PATCH 0990/1971] [IPX]: Fix NULL pointer dereference on ipx unload

Fixes a null pointer dereference when unloading the ipx module.

On initialization of the ipx module, registering certain packet
types can fail. When this happens, unloading the module later
dereferences NULL pointers.  This patch fixes that. Please apply.

Subject: [PATCH 0993/1971] ucc_geth: Add support to local-mac-address property
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

IEEE-1275 defines “local-mac-address� to be a standard
property name to specify preassigned network address.
This patch adds support for it.

Subject: [PATCH 0999/1971] [ALSA] usb-audio: merge playback/capture hardware
 information structs

The hardware information structures for playback and capture streams,
respectively, are the same, so we can use just one structure for both
streams.

Subject: [PATCH 1001/1971] [ALSA] Enable capture from line-in and CD on
 Revolution 5.1

Enable capture from line-in and CD on the Revolution 5.1 card.
This patch adds support for switching between the 5 input channels of
the AK5365 ADC and modifies the Revolution 5.1 driver to make use of
this facility.  Previously the capture channel was fixed to channel 0
(microphone on the Revolution 5.1 card).

From feaa6a74d852be40c0e717471aa92eead012052c Mon Sep 17 00:00:00 2001
From: Jochen Voss <voss@seehuhn.de>
Date: Wed, 4 Oct 2006 18:08:43 +0200
Subject: [PATCH 1002/1971] [ALSA] Enable the analog loopback of the Revolution
 5.1

Enable the analog loopback of the Revolution 5.1 card.
This patch adds support for the PT2258 volume controller and modifies
the Revolution 5.1 driver to make use of this facility.  This allows
to control the analog loopback of the card.

Subject: [PATCH 1003/1971] [ALSA] allow registering an alsa device with struct
 device pointer

This patch adds snd_register_device_for_dev taking a struct device
pointer to link the new device to and makes snd_register_device a simple
static inline wrapper around it.

Subject: [PATCH 1004/1971] [ALSA] alsa core: add struct device pointer to
 struct snd_pcm

This patch adds a struct device pointer to struct snd_pcm in order to be
able to give it a different device than the card. It defaults to the card's
device, however, so it should behave identically for drivers not touching
the field.

Subject: [PATCH 1006/1971] [ALSA] aoa: fix up i2sbus_attach_codec

This patch changes i2sbus_attach_codec to implement a proper error handling
strategy using labels to jump to the right part. Since it has an elaborate
set-up sequence it also needs that tear-down, which I had hard-coded
inbetween all the checks. This increases readability and should reduce .text
size as well.

From 9244b2c3079faac79b3b961116bd548c45087e2c Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes@sipsolutions.net>
Date: Thu, 5 Oct 2006 16:02:22 +0200
Subject: [PATCH 1007/1971] [ALSA] alsa core: convert to list_for_each_entry*

This patch converts most uses of list_for_each to list_for_each_entry all
across alsa. In some place apparently an item can be on a list with
different pointers so of course that isn't compatible with list_for_each, I
therefore didn't touch those places.

From db2a416556af0313db028147e4a22fef6f214f2f Mon Sep 17 00:00:00 2001
From: Frank Mandarino <fmandarino@endrelia.com>
Date: Fri, 6 Oct 2006 18:31:09 +0200
Subject: [PATCH 1013/1971] [ALSA] ASoC: core code

This patch is the core of ASoC functionality.
The ASoC core is designed to provide the following features :-
o  Codec independence. Allows reuse of codec drivers on other platforms
and machines.
o Platform driver code reuse. Reuse of platform specific audio DMA and
DAI drivers on different machines.
o Easy I2S/PCM digital audio interface configuration between codec and
SoC. Each SoC interface and codec registers their audio interface
capabilities with the core at initialisation. The capabilities are
subsequently matched and configured at run time for best power and
performance when the application hw params are known.
 o Machine specific controls/operations: Allow machines to add controls
and operations to the audio subsystem. e.g. volume control for speaker
amp.
To achieve all this, ASoC splits an embedded audio system into 3
components :-
1. Codec driver: The codec driver is platform independent and contains
audio controls, audio interface capabilities, codec dapm and codec IO
functions.
2. Platform driver: The platform driver contains the audio dma engine
and audio interface drivers (e.g. I2S, AC97, PCM) for that platform.
3. Machine driver: The machine driver handles any machine specific
controls and audio events. i.e. turning on an amp at start of playback.

From 2b97eabc09f42d0f63e8053636e34e1afa0d604e Mon Sep 17 00:00:00 2001
From: Richard Purdie <rpurdie@rpsys.net>
Date: Fri, 6 Oct 2006 18:32:18 +0200
Subject: [PATCH 1014/1971] [ALSA] ASoC: dynamic audio power management (DAPM)

This patch adds Dynamic Audio Power Management (DAPM) to ASoC.
Dynamic Audio Power Management (DAPM) is designed to allow portable and
handheld Linux devices to use the minimum amount of power within the
audio subsystem at all times. It is independent of other kernel PM and
as such, can easily co-exist with the other PM systems.
DAPM is also completely transparent to all user space applications as
all power switching is done within the ASoC core. No code changes or
recompiling are required for user space applications. DAPM makes power
switching decisions based upon any audio stream (capture/playback)
activity and audio mixer settings within the device.
DAPM spans the whole machine. It covers power control within the entire
audio subsystem, this includes internal codec power blocks and machine
level power systems.
There are 4 power domains within DAPM:-
1. Codec domain - VREF, VMID (core codec and audio power)
Usually controlled at codec probe/remove and suspend/resume, although
can be set at stream time if power is not needed for sidetone, etc.
2. Platform/Machine domain - physically connected inputs and outputs
Is platform/machine and user action specific, is configured by the
machine driver and responds to asynchronous events e.g when HP are
inserted
3. Path domain - audio subsystem signal paths
Automatically set when mixer and mux settings are changed by the user.
e.g. alsamixer, amixer.
4. Stream domain - DAC's and ADC's.
Enabled and disabled when stream playback/capture is started and stopped
respectively. e.g. aplay, arecord.
All DAPM power switching decisions are made automatically by consulting
an audio routing map of the whole machine. This map is specific to each
machine and consists of the interconnections between every audio
component (including internal codec components).

+ *
+ *  Revision history
+ *    12th Aug 2005   Initial version.
+ *    25th Oct 2005   Implemented path power domain.
+ *    18th Dec 2005   Implemented machine and stream level power domain.
+ *
+ *  Features:
+ *    o Changes power status of internal codec blocks depending on the
+ *      dynamic configuration of codec internal audio paths and active
+ *      DAC's/ADC's.
+ *    o Platform power domain - can support external components i.e. amps and
+ *      mic/meadphone insertion events.
+ *    o Automatic Mic Bias support
+ *    o Jack insertion power event initiation - e.g. hp insertion will enable
+ *      sinks, dacs, etc
+ *    o Delayed powerdown of audio susbsytem to reduce pops between a quick
+ *      device reopen.
+ *
+ *  Todo:
+ *    o DAPM power change sequencing - allow for configurable per
+ *      codec sequences.
+ *    o Support for analogue bias optimisation.
+ *    o Support for reduced codec oversampling rates.
+ *    o Support for reduced codec bias currents.

+ASoC currently supports the three main Digital Audio Interfaces (DAI) found on
+SoC controllers and portable audio CODECS today, namely AC97, I2S and PCM.
+
+
+AC97
+====
+
+  AC97 is a five wire interface commonly found on many PC sound cards. It is
+now also popular in many portable devices. This DAI has a reset line and time
+multiplexes its data on its SDATA_OUT (playback) and SDATA_IN (capture) lines.
+The bit clock (BCLK) is always driven by the CODEC (usually 12.288MHz) and the
+frame (FRAME) (usually 48kHz) is always driven by the controller. Each AC97
+frame is 21uS long and is divided into 13 time slots.
+
+The AC97 specification can be found at http://intel.com/
+
+
+I2S
+===
+
+ I2S is a common 4 wire DAI used in HiFi, STB and portable devices. The Tx and
+Rx lines are used for audio transmision, whilst the bit clock (BCLK) and
+left/right clock (LRC) synchronise the link. I2S is flexible in that either the
+controller or CODEC can drive (master) the BCLK and LRC clock lines. Bit clock
+usually varies depending on the sample rate and the master system clock
+(SYSCLK). LRCLK is the same as the sample rate. A few devices support separate
+ADC and DAC LRCLK's, this allows for similtanious capture and playback at
+different sample rates.
+
+I2S has several different operating modes:-
+
+ o I2S - MSB is transmitted on the falling edge of the first BCLK after LRC
+         transition.
+
+ o Left Justified - MSB is transmitted on transition of LRC.
+
+ o Right Justified - MSB is transmitted sample size BCLK's before LRC
+                     transition.
+
+PCM
+===
+
+PCM is another 4 wire interface, very similar to I2S, that can support a more
+flexible protocol. It has bit clock (BCLK) and sync (SYNC) lines that are used
+to synchronise the link whilst the Tx and Rx lines are used to transmit and
+receive the audio data. Bit clock usually varies depending on sample rate
+whilst sync runs at the sample rate. PCM also supports Time Division
+Multiplexing (TDM) in that several devices can use the bus similtaniuosly (This
+is sometimes referred to as network mode).
+
+Common PCM operating modes:-
+
+ o Mode A - MSB is transmitted on falling edge of first BCLK after FRAME/SYNC.
+
+ o Mode B - MSB is transmitted on rising edge of FRAME/SYNC.
+
+
+ASoC DAI Configuration
+======================
+
+Every CODEC DAI and SoC DAI must have their capabilities defined in order to
+be configured together at runtime when the audio and clocking parameters are
+known. This is achieved by creating an array of struct snd_soc_hw_mode in the
+the CODEC and SoC interface drivers. Each element in the array describes a DAI
+mode and each mode is usually based upon the DAI system clock to sample rate
+ratio (FS).
+
+i.e. 48k sample rate @ 256 FS = sytem clock of 12.288 MHz
+     48000 * 256 = 12288000
+
+The CPU and Codec DAI modes are then ANDed together at runtime to determine the
+rutime DAI configuration for both the Codec and CPU.
+
+When creating a new codec or SoC DAI it's probably best to start of with a few
+sample rates first and then test your interface.
+
+struct snd_soc_dai_mode is defined (in soc.h) as:-
+
+/* SoC DAI mode */
+struct snd_soc_hw_mode {
+	unsigned int fmt:16;		/* SND_SOC_DAIFMT_* */
+	unsigned int tdm:16;		/* SND_SOC_DAITDM_* */
+	unsigned int pcmfmt:6; 		/* SNDRV_PCM_FORMAT_* */
+	unsigned int pcmrate:16;	/* SND_SOC_DAIRATE_* */
+	unsigned int pcmdir:2;		/* SND_SOC_DAIDIR_* */
+	unsigned int flags:8;		/* hw flags */
+	unsigned int fs:32;			/* mclk to rate dividers */
+	unsigned int bfs:16;		/* mclk to bclk dividers */
+	unsigned long priv;	        /* private mode data */
+};
+
+fmt:
+----
+This field defines the DAI mode hardware format (e.g. I2S settings) and
+supports the following settings:-
+
+ 1) hardware DAI formats
+
+#define SND_SOC_DAIFMT_I2S        (1 << 0)	/* I2S mode */
+#define SND_SOC_DAIFMT_RIGHT_J    (1 << 1)	/* Right justified mode */
+#define SND_SOC_DAIFMT_LEFT_J     (1 << 2)	/* Left Justified mode */
+#define SND_SOC_DAIFMT_DSP_A      (1 << 3)	/* L data msb after FRM */
+#define SND_SOC_DAIFMT_DSP_B      (1 << 4)	/* L data msb during FRM */
+#define SND_SOC_DAIFMT_AC97       (1 << 5)	/* AC97 */
+
+ 2) hw DAI signal inversions
+
+#define SND_SOC_DAIFMT_NB_NF		(1 << 8)	/* normal bit clock + frame */
+#define SND_SOC_DAIFMT_NB_IF		(1 << 9)	/* normal bclk + inv frm */
+#define SND_SOC_DAIFMT_IB_NF		(1 << 10)	/* invert bclk + nor frm */
+#define SND_SOC_DAIFMT_IB_IF		(1 << 11)	/* invert bclk + frm */
+
+ 3) hw clock masters
+    This is wrt the codec, the inverse is true for the interface
+    i.e. if the codec is clk and frm master then the interface is
+    clk and frame slave.
+
+#define SND_SOC_DAIFMT_CBM_CFM		(1 << 12)	/* codec clk & frm master */
+#define SND_SOC_DAIFMT_CBS_CFM		(1 << 13)	/* codec clk slave & frm master */
+#define SND_SOC_DAIFMT_CBM_CFS		(1 << 14)	/* codec clk master & frame slave */
+#define SND_SOC_DAIFMT_CBS_CFS		(1 << 15)	/* codec clk & frm slave */
+
+At least one option from each section must be selected. Multiple selections are
+also supported e.g.
+
+ .fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_LEFT_J | SND_SOC_DAIFMT_RIGHT_J | \
+	SND_SOC_DAIFMT_NB_NF | SND_SOC_DAIFMT_NB_IF | SND_SOC_DAIFMT_IB_NF | \
+	SND_SOC_DAIFMT_IB_IF
+
+
+tdm:
+------
+This field defines the Time Division Multiplexing left and right word
+positions for the DAI mode if applicable. Set to SND_SOC_DAITDM_LRDW(0,0) for
+no TDM.
+
+
+pcmfmt:
+---------
+The hardware PCM format. This describes the PCM formats supported by the DAI
+mode e.g.
+
+ .hwpcmfmt = SNDRV_PCM_FORMAT_S16_LE | SNDRV_PCM_FORMAT_S20_3LE | \
+ 	SNDRV_PCM_FORMAT_S24_3LE
+
+pcmrate:
+----------
+The PCM sample rates supported by the DAI mode. e.g.
+
+ .hwpcmrate = SNDRV_PCM_RATE_8000 | SNDRV_PCM_RATE_11025 | SNDRV_PCM_RATE_16000 | \
+	SNDRV_PCM_RATE_22050 | SNDRV_PCM_RATE_32000 | SNDRV_PCM_RATE_44100 | \
+	SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_88200 | SNDRV_PCM_RATE_96000
+
+
+pcmdir:
+---------
+The stream directions supported by this mode. e.g. playback and capture
+
+
+flags:
+--------
+The DAI hardware flags supported by the mode.
+
+SND_SOC_DAI_BFS_DIV
+This flag states that bit clock is generated by dividing MCLK in this mode, if
+this flag is absent the bitclock generated by mulitiplying sample rate.
+
+NOTE: Bitclock division and mulitiplication modes can be safely matched by the
+core logic.
+
+
+fs:
+-----
+The FS supported by this DAI mode FS is the ratio between the system clock and
+the sample rate. See above
+
+bfs:
+------
+BFS is the ratio of BCLK to MCLK or the ratio of BCLK to sample rate (this
+depends on the codec or CPU DAI).
+
+The BFS supported by the DAI mode. This can either be the ratio between the
+bitclock (BCLK) and the sample rate OR the ratio between the system clock and
+the sample rate. Depends on the SND_SOC_DAI_BFS_DIV flag above.
+
+priv:
+-----
+private codec mode data.
+
+
+
+Examples
+========
+
+Note that Codec DAI and CPU DAI examples are interchangeable in these examples
+as long as the bus master is reversed. i.e.
+
+  SND_SOC_DAIFMT_CBM_CFM would become SND_SOC_DAIFMT_CBS_CFS
+  and vice versa.
+
+This applies to all SND_SOC_DAIFMT_CB*_CF*.
+
+Example 1

+Audio Clocking
+==============
+
+This text describes the audio clocking terms in ASoC and digital audio in
+general. Note: Audio clocking can be complex !
+
+
+Master Clock
+------------
+
+Every audio subsystem is driven by a master clock (sometimes refered to as MCLK
+or SYSCLK). This audio master clock can be derived from a number of sources
+(e.g. crystal, PLL, CPU clock) and is responsible for producing the correct
+audio playback and capture sample rates.
+
+Some master clocks (e.g. PLL's and CPU based clocks) are configuarble in that
+their speed can be altered by software (depending on the system use and to save
+power). Other master clocks are fixed at at set frequency (i.e. crystals).
+
+
+DAI Clocks
+----------
+The Digital Audio Interface is usually driven by a Bit Clock (often referred to
+as BCLK). This clock is used to drive the digital audio data across the link
+between the codec and CPU.
+
+The DAI also has a frame clock to signal the start of each audio frame. This
+clock is sometimes referred to as LRC (left right clock) or FRAME. This clock
+runs at exactly the sample rate.
+
+Bit Clock is usually always a ratio of MCLK or a multiple of LRC. i.e.
+
+BCLK = MCLK / x
+
+ or
+
+BCLK = LRC * x
+
+This relationship depends on the codec or SoC CPU in particular. ASoC can quite
+easily match a codec that generates BCLK by division (FSBD) with a CPU that
+generates BCLK by multiplication (FSB).
+
+
+ASoC Clocking
+-------------
+
+The ASoC core determines the clocking for each particular configuration at
+runtime. This is to allow for dynamic audio clocking wereby the audio clock is
+variable and depends on the system state or device usage scenario. i.e. a voice
+call requires slower clocks (and hence less power) than MP3 playback.
+
+ASoC will call the config_sysclock() function for the target machine during the
+audio parameters configuration. The function is responsible for then clocking
+the machine audio subsytem and returning the audio clock speed to the core.
+This function should also call the codec and cpu DAI clock_config() functions
+to configure their respective internal clocking if required.
+
+
+ASoC Clocking Control Flow
+--------------------------
+
+The ASoC core will call the machine drivers config_sysclock() when most of the
+DAI capabilities are known. The machine driver is then responsible for calling
+the codec and/or CPU DAI drivers with the selected capabilities and the current
+MCLK. Note that the machine driver is also resonsible for setting the MCLK (and
+enabling it).
+
+   (1) Match Codec and CPU DAI capabilities. At this point we have
+       matched the majority of the DAI fields and now need to make sure this
+       mode is currently clockable.
+
+   (2) machine->config_sysclk() is now called with the matched DAI FS, sample
+       rate and BCLK master. This function then gets/sets the current audio
+       clock (depening on usage) and calls the codec and CPUI DAI drivers with
+       the FS, rate, BCLK master and MCLK.
+
+   (3) Codec/CPU DAI config_sysclock(). This function checks that the FS, rate,
+       BCLK master and MCLK are acceptable for the codec or CPU DAI. It also
+       sets the DAI internal state to work with said clocks.
+
+The config_sysclk() functions for CPU, codec and machine should return the MCLK
+on success and 0 on failure.
+
+
+Examples (b = BCLK, l = LRC)
+============================
+
+Example 1
+---------
+
+Simple codec that only runs at 48k @ 256FS in master mode.
+
+CPU only runs as slave DAI, however it generates a variable MCLK.
+
+             --------                 ---------
+            |        | <----mclk---  |         |
+            | Codec  |b -----------> |  CPU    |
+            |        |l -----------> |         |
+            |        |               |         |
+             --------                 ---------
+
+The codec driver has the following config_sysclock()
+
+	static unsigned int config_sysclk(struct snd_soc_codec_dai *dai,
+		struct snd_soc_clock_info *info, unsigned int clk)
+	{
+		/* make sure clock is 256 * rate */
+		if(info->rate << 8 == clk) {
+			dai->mclk = clk;
+			return clk;
+		}
+
+		return 0;
+	}
+
+The CPU I2S DAI driver has the following config_sysclk()
+
+	static unsigned int config_sysclk(struct snd_soc_codec_dai *dai,
+		struct snd_soc_clock_info *info, unsigned int clk)
+	{
+		/* can we support this clk */
+		if(set_audio_clk(clk) < 0)
+			return -EINVAL;
+
+		dai->mclk = clk;
+		return dai->clk;
+	}
+
+The machine driver config_sysclk() in this example is as follows:-
+
+	unsigned int machine_config_sysclk(struct snd_soc_pcm_runtime *rtd,
+		struct snd_soc_clock_info *info)
+	{
+		int clk = info->rate * info->fs;
+
+		/* check that CPU can deliver clock */
+		if(rtd->cpu_dai->config_sysclk(rtd->cpu_dai, info, clk) < 0)
+			return -EINVAL;
+
+		/* can codec work with this clock */
+		return rtd->codec_dai->config_sysclk(rtd->codec_dai, info, clk);
+	}
+
+
+Example 2
+---------
+
+Codec that can master at 8k and 48k at various FS (and hence supports a fixed
+set of input MCLK's) and can also be slave at various FS .
+
+The CPU can master at 8k and 48k @256 FS and can be slave at any FS.
+
+MCLK is a 12.288MHz crystal on this machine.
+
+             --------                 ---------
+            |        |  <---xtal---> |         |
+            | Codec  |b <----------> |  CPU    |
+            |        |l <----------> |         |
+            |        |               |         |
+             --------                 ---------
+
+
+The codec driver has the following config_sysclock()
+
+	/* supported input clocks */
+	const static int hifi_clks[] = {11289600, 12000000, 12288000,
+		16934400, 18432000};
+
+	static unsigned int config_hsysclk(struct snd_soc_codec_dai *dai,
+		struct snd_soc_clock_info *info, unsigned int clk)
+	{
+		int i;
+
+		/* is clk supported  */
+		for(i = 0; i < ARRAY_SIZE(hifi_clks); i++) {
+			if(clk == hifi_clks[i]) {
+				dai->mclk = clk;
+				return clk;
+			}
+		}
+
+		/* this clk is not supported */
+		return 0;
+	}
+
+The CPU I2S DAI driver has the following config_sysclk()
+
+	static unsigned int config_sysclk(struct snd_soc_codec_dai *dai,
+		struct snd_soc_clock_info *info, unsigned int clk)
+	{
+		/* are we master or slave */
+		if (info->bclk_master &
+			(SND_SOC_DAIFMT_CBM_CFM | SND_SOC_DAIFMT_CBM_CFS)) {
+
+			/* we can only master @ 256FS */
+			if(info->rate << 8 == clk) {
+				dai->mclk = clk;
+				return dai->mclk;
+			}
+		} else {
+			/* slave we can run at any FS */
+			dai->mclk = clk;
+			return dai->mclk;
+		}
+
+		/* not supported */
+		return dai->clk;
+	}
+
+The machine driver config_sysclk() in this example is as follows:-
+
+	unsigned int machine_config_sysclk(struct snd_soc_pcm_runtime *rtd,
+		struct snd_soc_clock_info *info)
+	{
+		int clk = 12288000; /* 12.288MHz */
+
+		/* who's driving the link */
+		if (info->bclk_master &
+			(SND_SOC_DAIFMT_CBM_CFM | SND_SOC_DAIFMT_CBM_CFS)) {
+			/* codec master */
+
+			/* check that CPU can work with clock */
+			if(rtd->cpu_dai->config_sysclk(rtd->cpu_dai, info, clk) < 0)
+				return -EINVAL;
+
+			/* can codec work with this clock */
+			return rtd->codec_dai->config_sysclk(rtd->codec_dai, info, clk);
+		} else {
+			/* cpu master */
+
+			/* check that codec can work with clock */
+			if(rtd->codec_dai->config_sysclk(rtd->codec_dai, info, clk) < 0)
+				return -EINVAL;
+
+			/* can CPU work with this clock */
+			return rtd->cpu_dai->config_sysclk(rtd->cpu_dai, info, clk);
+		}
+	}
+
+
+
+Example 3
+---------
+
+Codec that masters at 8k ... 48k @256 FS. Codec can also be slave and
+doesn't care about FS. The codec has an internal PLL and dividers to generate
+the necessary internal clocks (for 256FS).
+
+CPU can only be slave and doesn't care about FS.
+
+MCLK is a non controllable 13MHz clock from the CPU.
+
+
+             --------                 ---------
+            |        | <----mclk---  |         |
+            | Codec  |b <----------> |  CPU    |

+             --------                 ---------
+
+The codec driver has the following config_sysclock()
+
+	/* valid PCM clock dividers * 2 */

+ASoC Codec Driver
+=================
+
+The codec driver is generic and hardware independent code that configures the
+codec to provide audio capture and playback. It should contain no code that is
+specific to the target platform or machine. All platform and machine specific
+code should be added to the platform and machine drivers respectively.
+
+Each codec driver must provide the following features:-
+
+ 1) Digital audio interface (DAI) description
+ 2) Digital audio interface configuration
+ 3) PCM's description
+ 4) Codec control IO - using I2C, 3 Wire(SPI) or both API's
+ 5) Mixers and audio controls
+ 6) Sysclk configuration
+ 7) Codec audio operations
+
+Optionally, codec drivers can also provide:-
+
+ 8) DAPM description.
+ 9) DAPM event handler.
+10) DAC Digital mute control.
+
+It's probably best to use this guide in conjuction with the existing codec
+driver code in sound/soc/codecs/
+
+ASoC Codec driver breakdown
+===========================
+
+1 - Digital Audio Interface (DAI) description
+---------------------------------------------
+The DAI is a digital audio data transfer link between the codec and host SoC
+CPU. It typically has data transfer capabilities in both directions
+(playback and capture) and can run at a variety of different speeds.
+Supported interfaces currently include AC97, I2S and generic PCM style links.
+Please read DAI.txt for implementation information.
+
+
+2 - Digital Audio Interface (DAI) configuration
+-----------------------------------------------
+DAI configuration is handled by the codec_pcm_prepare function and is
+responsible for configuring and starting the DAI on the codec. This can be
+called multiple times and is atomic. It can access the runtime parameters.
+
+This usually consists of a large function with numerous switch statements to
+set up each configuration option. These options are set by the core at runtime.
+
+
+3 - Codec PCM's
+---------------
+Each codec must have it's PCM's defined. This defines the number of channels,
+stream names, callbacks and codec name. It is also used to register the DAI
+with the ASoC core. The PCM structure also associates the DAI capabilities with
+the ALSA PCM.
+
+e.g.
+
+static struct snd_soc_pcm_codec wm8731_pcm_client = {
+	.name = "WM8731",
+	.playback = {
+		.stream_name = "Playback",
+		.channels_min = 1,
+		.channels_max = 2,
+	},
+	.capture = {
+		.stream_name = "Capture",
+		.channels_min = 1,
+		.channels_max = 2,
+	},
+	.config_sysclk = wm8731_config_sysclk,
+	.ops = {
+		.prepare = wm8731_pcm_prepare,
+	},
+	.caps = {
+		.num_modes = ARRAY_SIZE(wm8731_hwfmt),
+		.modes = &wm8731_hwfmt[0],
+	},
+};
+
+
+4 - Codec control IO
+--------------------
+The codec can ususally be controlled via an I2C or SPI style interface (AC97
+combines control with data in the DAI). The codec drivers will have to provide
+functions to read and write the codec registers along with supplying a register
+cache:-
+
+	/* IO control data and register cache */
+    void *control_data; /* codec control (i2c/3wire) data */
+    void *reg_cache;
+
+Codec read/write should do any data formatting and call the hardware read write
+below to perform the IO. These functions are called by the core and alsa when
+performing DAPM or changing the mixer:-
+
+    unsigned int (*read)(struct snd_soc_codec *, unsigned int);
+    int (*write)(struct snd_soc_codec *, unsigned int, unsigned int);
+
+Codec hardware IO functions - usually points to either the I2C, SPI or AC97
+read/write:-
+
+	hw_write_t hw_write;
+	hw_read_t hw_read;
+
+
+5 - Mixers and audio controls
+-----------------------------
+All the codec mixers and audio controls can be defined using the convenience
+macros defined in soc.h.
+
+    #define SOC_SINGLE(xname, reg, shift, mask, invert)
+
+Defines a single control as follows:-
+
+  xname = Control name e.g. "Playback Volume"
+  reg = codec register
+  shift = control bit(s) offset in register
+  mask = control bit size(s) e.g. mask of 7 = 3 bits
+  invert = the control is inverted
+
+Other macros include:-
+
+    #define SOC_DOUBLE(xname, reg, shift_left, shift_right, mask, invert)
+
+A stereo control
+
+    #define SOC_DOUBLE_R(xname, reg_left, reg_right, shift, mask, invert)
+
+A stereo control spanning 2 registers
+
+    #define SOC_ENUM_SINGLE(xreg, xshift, xmask, xtexts)
+
+Defines an single enumerated control as follows:-
+
+   xreg = register
+   xshift = control bit(s) offset in register
+   xmask = control bit(s) size
+   xtexts = pointer to array of strings that describe each setting
+
+   #define SOC_ENUM_DOUBLE(xreg, xshift_l, xshift_r, xmask, xtexts)
+
+Defines a stereo enumerated control
+
+
+6 - System clock configuration.
+-------------------------------
+The system clock that drives the audio subsystem can change depending on sample
+rate and the system power state. i.e.
+
+o Higher sample rates sometimes need a higher system clock.
+o Low system power states can sometimes limit the available clocks.
+
+This function is a callback that the machine driver can call to set and
+determine if the clock and sample rate combination is supported by the codec at
+the present time (and system state).
+
+NOTE: If the codec has a PLL then it has a lot more flexability wrt clock and
+sample rate combinations.
+
+Your config_sysclock function should return the MCLK if it's a valid
+combination for your codec else 0;
+
+Please read clocking.txt now.
+
+
+7 - Codec Audio Operations
+--------------------------
+The codec driver also supports the following alsa operations:-
+
+/* SoC audio ops */
+struct snd_soc_ops {
+	int (*startup)(snd_pcm_substream_t *);
+	void (*shutdown)(snd_pcm_substream_t *);
+	int (*hw_params)(snd_pcm_substream_t *, snd_pcm_hw_params_t *);
+	int (*hw_free)(snd_pcm_substream_t *);
+	int (*prepare)(snd_pcm_substream_t *);
+};
+
+Please refer to the alsa driver PCM documentation for details.
+http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
+
+
+8 - DAPM description.
+---------------------
+The Dynamic Audio Power Management description describes the codec's power
+components, their relationships and registers to the ASoC core. Please read
+dapm.txt for details of building the description.
+
+Please also see the examples in other codec drivers.
+
+
+9 - DAPM event handler
+----------------------
+This function is a callback that handles codec domain PM calls and system
+domain PM calls (e.g. suspend and resume). It's used to put the codec to sleep
+when not in use.
+
+Power states:-
+
+	SNDRV_CTL_POWER_D0: /* full On */
+	/* vref/mid, clk and osc on, active */
+
+	SNDRV_CTL_POWER_D1: /* partial On */
+	SNDRV_CTL_POWER_D2: /* partial On */
+
+	SNDRV_CTL_POWER_D3hot: /* Off, with power */
+	/* everything off except vref/vmid, inactive */
+
+	SNDRV_CTL_POWER_D3cold: /* Everything Off, without power */
+
+
+10 - Codec DAC digital mute control.
+------------------------------------
+Most codecs have a digital mute before the DAC's that can be used to minimise
+any system noise.  The mute stops any digital data from entering the DAC.
+
+A callback can be created that is called by the core for each codec DAI when the
+mute is applied or freed.
+
+i.e.
+
+static int wm8974_mute(struct snd_soc_codec *codec,
+	struct snd_soc_codec_dai *dai, int mute)
+{
+	u16 mute_reg = wm8974_read_reg_cache(codec, WM8974_DAC) & 0xffbf;
+	if(mute)
+		wm8974_write(codec, WM8974_DAC, mute_reg | 0x40);
+	else
+		wm8974_write(codec, WM8974_DAC, mute_reg);
+	return 0;
+}

+Dynamic Audio Power Management for Portable Devices
+===================================================
+
+1. Description
+==============
+
+Dynamic Audio Power Management (DAPM) is designed to allow portable Linux devices
+to use the minimum amount of power within the audio subsystem at all times. It
+is independent of other kernel PM and as such, can easily co-exist with the
+other PM systems.
+
+DAPM is also completely transparent to all user space applications as all power
+switching is done within the ASoC core. No code changes or recompiling are
+required for user space applications. DAPM makes power switching descisions based
+upon any audio stream (capture/playback) activity and audio mixer settings
+within the device.
+
+DAPM spans the whole machine. It covers power control within the entire audio
+subsystem, this includes internal codec power blocks and machine level power
+systems.
+
+There are 4 power domains within DAPM
+
+   1. Codec domain - VREF, VMID (core codec and audio power)
+      Usually controlled at codec probe/remove and suspend/resume, although
+      can be set at stream time if power is not needed for sidetone, etc.
+
+   2. Platform/Machine domain - physically connected inputs and outputs
+      Is platform/machine and user action specific, is configured by the
+      machine driver and responds to asynchronous events e.g when HP
+      are inserted
+
+   3. Path domain - audio susbsystem signal paths
+      Automatically set when mixer and mux settings are changed by the user.
+      e.g. alsamixer, amixer.
+
+   4. Stream domain - DAC's and ADC's.
+      Enabled and disabled when stream playback/capture is started and
+      stopped respectively. e.g. aplay, arecord.
+
+All DAPM power switching descisons are made automatically by consulting an audio
+routing map of the whole machine. This map is specific to each machine and
+consists of the interconnections between every audio component (including
+internal codec components). All audio components that effect power are called
+widgets hereafter.
+
+
+2. DAPM Widgets
+===============
+
+Audio DAPM widgets fall into a number of types:-
+
+ o Mixer      - Mixes several analog signals into a single analog signal.
+ o Mux        - An analog switch that outputs only 1 of it's inputs.
+ o PGA        - A programmable gain amplifier or attenuation widget.
+ o ADC        - Analog to Digital Converter
+ o DAC        - Digital to Analog Converter
+ o Switch     - An analog switch
+ o Input      - A codec input pin
+ o Output     - A codec output pin
+ o Headphone  - Headphone (and optional Jack)
+ o Mic        - Mic (and optional Jack)
+ o Line       - Line Input/Output (and optional Jack)
+ o Speaker    - Speaker
+ o Pre        - Special PRE widget (exec before all others)
+ o Post       - Special POST widget (exec after all others)
+
+(Widgets are defined in include/sound/soc-dapm.h)
+
+Widgets are usually added in the codec driver and the machine driver. There are
+convience macros defined in soc-dapm.h that can be used to quickly build a
+list of widgets of the codecs and machines DAPM widgets.
+
+Most widgets have a name, register, shift and invert. Some widgets have extra
+parameters for stream name and kcontrols.
+
+
+2.1 Stream Domain Widgets
+-------------------------
+
+Stream Widgets relate to the stream power domain and only consist of ADC's
+(analog to digital converters) and DAC's (digital to analog converters).
+
+Stream widgets have the following format:-
+
+SND_SOC_DAPM_DAC(name, stream name, reg, shift, invert),
+
+NOTE: the stream name must match the corresponding stream name in your codecs
+snd_soc_codec_dai.
+
+e.g. stream widgets for HiFi playback and capture
+
+SND_SOC_DAPM_DAC("HiFi DAC", "HiFi Playback", REG, 3, 1),
+SND_SOC_DAPM_ADC("HiFi ADC", "HiFi Capture", REG, 2, 1),
+
+
+2.2 Path Domain Widgets
+-----------------------
+
+Path domain widgets have a ability to control or effect the audio signal or
+audio paths within the audio subsystem. They have the following form:-
+
+SND_SOC_DAPM_PGA(name, reg, shift, invert, controls, num_controls)
+
+Any widget kcontrols can be set using the controls and num_controls members.
+
+e.g. Mixer widget (the kcontrols are declared first)
+
+/* Output Mixer */
+static const snd_kcontrol_new_t wm8731_output_mixer_controls[] = {
+SOC_DAPM_SINGLE("Line Bypass Switch", WM8731_APANA, 3, 1, 0),
+SOC_DAPM_SINGLE("Mic Sidetone Switch", WM8731_APANA, 5, 1, 0),
+SOC_DAPM_SINGLE("HiFi Playback Switch", WM8731_APANA, 4, 1, 0),
+};
+
+SND_SOC_DAPM_MIXER("Output Mixer", WM8731_PWR, 4, 1, wm8731_output_mixer_controls,
+	ARRAY_SIZE(wm8731_output_mixer_controls)),
+
+
+2.3 Platform/Machine domain Widgets
+-----------------------------------
+
+Machine widgets are different from codec widgets in that they don't have a
+codec register bit associated with them. A machine widget is assigned to each
+machine audio component (non codec) that can be independently powered. e.g.
+
+ o Speaker Amp
+ o Microphone Bias
+ o Jack connectors
+
+A machine widget can have an optional call back.
+
+e.g. Jack connector widget for an external Mic that enables Mic Bias
+when the Mic is inserted:-
+
+static int spitz_mic_bias(struct snd_soc_dapm_widget* w, int event)
+{
+	if(SND_SOC_DAPM_EVENT_ON(event))
+		set_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
+	else
+		reset_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
+
+	return 0;
+}
+
+SND_SOC_DAPM_MIC("Mic Jack", spitz_mic_bias),
+
+
+2.4 Codec Domain
+----------------
+
+The Codec power domain has no widgets and is handled by the codecs DAPM event
+handler. This handler is called when the codec powerstate is changed wrt to any
+stream event or by kernel PM events.
+
+
+2.5 Virtual Widgets
+-------------------
+
+Sometimes widgets exist in the codec or machine audio map that don't have any
+corresponding register bit for power control. In this case it's necessary to
+create a virtual widget - a widget with no control bits e.g.
+
+SND_SOC_DAPM_MIXER("AC97 Mixer", SND_SOC_DAPM_NOPM, 0, 0, NULL, 0),
+
+This can be used to merge to signal paths together in software.
+
+After all the widgets have been defined, they can then be added to the DAPM
+subsystem individually with a call to snd_soc_dapm_new_control().
+
+
+3. Codec Widget Interconnections
+================================
+
+Widgets are connected to each other within the codec and machine by audio
+paths (called interconnections). Each interconnection must be defined in order
+to create a map of all audio paths between widgets.
+This is easiest with a diagram of the codec (and schematic of the machine audio
+system), as it requires joining widgets together via their audio signal paths.
+
+i.e. from the WM8731 codec's output mixer (wm8731.c)
+
+The WM8731 output mixer has 3 inputs (sources)
+
+ 1. Line Bypass Input
+ 2. DAC (HiFi playback)
+ 3. Mic Sidetone Input
+
+Each input in this example has a kcontrol associated with it (defined in example
+above) and is connected to the output mixer via it's kcontrol name. We can now
+connect the destination widget (wrt audio signal) with it's source widgets.
+
+	/* output mixer */
+	{"Output Mixer", "Line Bypass Switch", "Line Input"},
+	{"Output Mixer", "HiFi Playback Switch", "DAC"},
+	{"Output Mixer", "Mic Sidetone Switch", "Mic Bias"},
+
+So we have :-
+
+	Destination Widget  <=== Path Name <=== Source Widget
+
+Or:-
+
+	Sink, Path, Source
+
+Or :-
+
+	"Output Mixer" is connected to the "DAC" via the "HiFi Playback Switch".
+
+When there is no path name connecting widgets (e.g. a direct connection) we
+pass NULL for the path name.
+
+Interconnections are created with a call to:-
+
+snd_soc_dapm_connect_input(codec, sink, path, source);
+
+Finally, snd_soc_dapm_new_widgets(codec) must be called after all widgets and
+interconnections have been registered with the core. This causes the core to
+scan the codec and machine so that the internal DAPM state matches the
+physical state of the machine.
+
+
+3.1 Machine Widget Interconnections
+-----------------------------------
+Machine widget interconnections are created in the same way as codec ones and
+directly connect the codec pins to machine level widgets.
+
+e.g. connects the speaker out codec pins to the internal speaker.
+
+	/* ext speaker connected to codec pins LOUT2, ROUT2  */
+	{"Ext Spk", NULL , "ROUT2"},
+	{"Ext Spk", NULL , "LOUT2"},
+
+This allows the DAPM to power on and off pins that are connected (and in use)
+and pins that are NC respectively.
+
+
+4 Endpoint Widgets
+===================
+An endpoint is a start or end point (widget) of an audio signal within the
+machine and includes the codec. e.g.
+
+ o Headphone Jack
+ o Internal Speaker
+ o Internal Mic
+ o Mic Jack
+ o Codec Pins
+
+When a codec pin is NC it can be marked as not used with a call to
+
+snd_soc_dapm_set_endpoint(codec, "Widget Name", 0);
+
+The last argument is 0 for inactive and 1 for active. This way the pin and its
+input widget will never be powered up and consume power.
+
+This also applies to machine widgets. e.g. if a headphone is connected to a
+jack then the jack can be marked active. If the headphone is removed, then
+the headphone jack can be marked inactive.
+
+
+5 DAPM Widget Events
+====================
+
+Some widgets can register their interest with the DAPM core in PM events.
+e.g. A Speaker with an amplifier registers a widget so the amplifier can be
+powered only when the spk is in use.
+
+/* turn speaker amplifier on/off depending on use */
+static int corgi_amp_event(struct snd_soc_dapm_widget *w, int event)
+{
+	if (SND_SOC_DAPM_EVENT_ON(event))
+		set_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
+	else
+		reset_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
+
+	return 0;
+}
+
+/* corgi machine dapm widgets */
+static const struct snd_soc_dapm_widget wm8731_dapm_widgets =
+	SND_SOC_DAPM_SPK("Ext Spk", corgi_amp_event);
+
+Please see soc-dapm.h for all other widgets that support events.
+
+
+5.1 Event types
+---------------
+
+The following event types are supported by event widgets.
+
+/* dapm event types */
+#define SND_SOC_DAPM_PRE_PMU	0x1 	/* before widget power up */
+#define SND_SOC_DAPM_POST_PMU	0x2		/* after widget power up */
+#define SND_SOC_DAPM_PRE_PMD	0x4 	/* before widget power down */
+#define SND_SOC_DAPM_POST_PMD	0x8		/* after widget power down */
+#define SND_SOC_DAPM_PRE_REG	0x10	/* before audio path setup */
+#define SND_SOC_DAPM_POST_REG	0x20	/* after audio path setup */

+ASoC Machine Driver
+===================
+
+The ASoC machine (or board) driver is the code that glues together the platform
+and codec drivers.
+
+The machine driver can contain codec and platform specific code. It registers
+the audio subsystem with the kernel as a platform device and is represented by
+the following struct:-
+
+/* SoC machine */
+struct snd_soc_machine {
+	char *name;
+
+	int (*probe)(struct platform_device *pdev);
+	int (*remove)(struct platform_device *pdev);
+
+	/* the pre and post PM functions are used to do any PM work before and
+	 * after the codec and DAI's do any PM work. */
+	int (*suspend_pre)(struct platform_device *pdev, pm_message_t state);
+	int (*suspend_post)(struct platform_device *pdev, pm_message_t state);
+	int (*resume_pre)(struct platform_device *pdev);
+	int (*resume_post)(struct platform_device *pdev);
+
+	/* machine stream operations */
+	struct snd_soc_ops *ops;
+
+	/* CPU <--> Codec DAI links  */
+	struct snd_soc_dai_link *dai_link;
+	int num_links;
+};
+
+probe()/remove()
+----------------
+probe/remove are optional. Do any machine specific probe here.
+
+
+suspend()/resume()
+------------------
+The machine driver has pre and post versions of suspend and resume to take care
+of any machine audio tasks that have to be done before or after the codec, DAI's
+and DMA is suspended and resumed. Optional.
+
+
+Machine operations
+------------------
+The machine specific audio operations can be set here. Again this is optional.
+
+
+Machine DAI Configuration
+-------------------------
+The machine DAI configuration glues all the codec and CPU DAI's together. It can
+also be used to set up the DAI system clock and for any machine related DAI
+initialisation e.g. the machine audio map can be connected to the codec audio
+map, unconnnected codec pins can be set as such. Please see corgi.c, spitz.c
+for examples.
+
+struct snd_soc_dai_link is used to set up each DAI in your machine. e.g.
+
+/* corgi digital audio interface glue - connects codec <--> CPU */
+static struct snd_soc_dai_link corgi_dai = {
+	.name = "WM8731",
+	.stream_name = "WM8731",
+	.cpu_dai = &pxa_i2s_dai,
+	.codec_dai = &wm8731_dai,
+	.init = corgi_wm8731_init,
+	.config_sysclk = corgi_config_sysclk,
+};
+
+struct snd_soc_machine then sets up the machine with it's DAI's. e.g.
+
+/* corgi audio machine driver */
+static struct snd_soc_machine snd_soc_machine_corgi = {
+	.name = "Corgi",
+	.dai_link = &corgi_dai,
+	.num_links = 1,
+	.ops = &corgi_ops,
+};
+
+
+Machine Audio Subsystem
+-----------------------
+
+The machine soc device glues the platform, machine and codec driver together.
+Private data can also be set here. e.g.
+
+/* corgi audio private data */
+static struct wm8731_setup_data corgi_wm8731_setup = {
+	.i2c_address = 0x1b,
+};
+
+/* corgi audio subsystem */
+static struct snd_soc_device corgi_snd_devdata = {
+	.machine = &snd_soc_machine_corgi,
+	.platform = &pxa2xx_soc_platform,
+	.codec_dev = &soc_codec_dev_wm8731,
+	.codec_data = &corgi_wm8731_setup,
+};
+
+
+Machine Power Map
+-----------------
+
+The machine driver can optionally extend the codec power map and to become an
+audio power map of the audio subsystem. This allows for automatic power up/down
+of speaker/HP amplifiers, etc. Codec pins can be connected to the machines jack
+sockets in the machine init function. See soc/pxa/spitz.c and dapm.txt for
+details.
+
+
+Machine Controls
+----------------
+
+Machine specific audio mixer controls can be added in the dai init function.

+ALSA SoC Layer
+==============
+
+The overall project goal of the ALSA System on Chip (ASoC) layer is to provide
+better ALSA support for embedded system on chip procesors (e.g. pxa2xx, au1x00,
+iMX, etc) and portable audio codecs. Currently there is some support in the
+kernel for SoC audio, however it has some limitations:-
+
+  * Currently, codec drivers are often tightly coupled to the underlying SoC
+    cpu. This is not ideal and leads to code duplication i.e. Linux now has 4
+    different wm8731 drivers for 4 different SoC platforms.
+
+  * There is no standard method to signal user initiated audio events.
+    e.g. Headphone/Mic insertion, Headphone/Mic detection after an insertion
+    event. These are quite common events on portable devices and ofter require
+    machine specific code to re route audio, enable amps etc after such an event.
+
+  * Current drivers tend to power up the entire codec when playing
+    (or recording) audio. This is fine for a PC, but tends to waste a lot of
+    power on portable devices. There is also no support for saving power via
+    changing codec oversampling rates, bias currents, etc.
+
+
+ASoC Design
+===========
+
+The ASoC layer is designed to address these issues and provide the following
+features :-
+
+  * Codec independence. Allows reuse of codec drivers on other platforms
+    and machines.
+
+  * Easy I2S/PCM audio interface setup between codec and SoC. Each SoC interface
+    and codec registers it's audio interface capabilities with the core and are
+    subsequently matched and configured when the application hw params are known.
+
+  * Dynamic Audio Power Management (DAPM). DAPM automatically sets the codec to
+    it's minimum power state at all times. This includes powering up/down
+    internal power blocks depending on the internal codec audio routing and any
+    active streams.
+
+  * Pop and click reduction. Pops and clicks can be reduced by powering the
+    codec up/down in the correct sequence (including using digital mute). ASoC
+    signals the codec when to change power states.
+
+  * Machine specific controls: Allow machines to add controls to the sound card
+    e.g. volume control for speaker amp.
+
+To achieve all this, ASoC basically splits an embedded audio system into 3
+components :-
+
+  * Codec driver: The codec driver is platform independent and contains audio
+    controls, audio interface capabilities, codec dapm definition and codec IO
+    functions.
+
+  * Platform driver: The platform driver contains the audio dma engine and audio
+    interface drivers (e.g. I2S, AC97, PCM) for that platform.
+
+  * Machine driver: The machine driver handles any machine specific controls and
+    audio events. i.e. turing on an amp at start of playback.

+ASoC Platform Driver
+====================
+
+An ASoC platform driver can be divided into audio DMA and SoC DAI configuration
+and control. The platform drivers only target the SoC CPU and must have no board
+specific code.
+
+Audio DMA
+=========
+
+The platform DMA driver optionally supports the following alsa operations:-
+
+/* SoC audio ops */
+struct snd_soc_ops {
+	int (*startup)(snd_pcm_substream_t *);
+	void (*shutdown)(snd_pcm_substream_t *);
+	int (*hw_params)(snd_pcm_substream_t *, snd_pcm_hw_params_t *);
+	int (*hw_free)(snd_pcm_substream_t *);
+	int (*prepare)(snd_pcm_substream_t *);
+	int (*trigger)(snd_pcm_substream_t *, int);
+};
+
+The platform driver exports it's DMA functionailty via struct snd_soc_platform:-
+
+struct snd_soc_platform {
+	char *name;
+
+	int (*probe)(struct platform_device *pdev);
+	int (*remove)(struct platform_device *pdev);
+	int (*suspend)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
+	int (*resume)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
+
+	/* pcm creation and destruction */
+	int (*pcm_new)(snd_card_t *, struct snd_soc_codec_dai *, snd_pcm_t *);
+	void (*pcm_free)(snd_pcm_t *);
+
+	/* platform stream ops */
+	snd_pcm_ops_t *pcm_ops;
+};
+
+Please refer to the alsa driver documentation for details of audio DMA.
+http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
+
+An example DMA driver is soc/pxa/pxa2xx-pcm.c
+
+
+SoC DAI Drivers
+===============
+
+Each SoC DAI driver must provide the following features:-
+
+ 1) Digital audio interface (DAI) description
+ 2) Digital audio interface configuration
+ 3) PCM's description
+ 4) Sysclk configuration
+ 5) Suspend and resume (optional)
+
+Please see codec.txt for a description of items 1 - 4.

+Audio Pops and Clicks
+=====================
+
+Pops and clicks are unwanted audio artifacts caused by the powering up and down
+of components within the audio subsystem. This is noticable on PC's when an audio
+module is either loaded or unloaded (at module load time the sound card is
+powered up and causes a popping noise on the speakers).
+
+Pops and clicks can be more frequent on portable systems with DAPM. This is because
+the components within the subsystem are being dynamically powered depending on
+the audio usage and this can subsequently cause a small pop or click every time a
+component power state is changed.
+
+
+Minimising Playback Pops and Clicks
+===================================
+
+Playback pops in portable audio subsystems cannot be completely eliminated atm,
+however future audio codec hardware will have better pop and click supression.
+Pops can be reduced within playback by powering the audio components in a
+specific order. This order is different for startup and shutdown and follows
+some basic rules:-
+
+ Startup Order :- DAC --> Mixers --> Output PGA --> Digital Unmute
+
+ Shutdown Order :- Digital Mute --> Output PGA --> Mixers --> DAC
+
+This assumes that the codec PCM output path from the DAC is via a mixer and then
+a PGA (programmable gain amplifier) before being output to the speakers.
+
+
+Minimising Capture Pops and Clicks
+==================================
+
+Capture artifacts are somewhat easier to get rid as we can delay activating the
+ADC until all the pops have occured. This follows similar power rules to
+playback in that components are powered in a sequence depending upon stream
+startup or shutdown.
+
+ Startup Order - Input PGA --> Mixers --> ADC
+
+ Shutdown Order - ADC --> Mixers --> Input PGA
+
+
+Zipper Noise
+============
+An unwanted zipper noise can occur within the audio playback or capture stream
+when a volume control is changed near its maximum gain value. The zipper noise
+is heard when the gain increase or decrease changes the mean audio signal
+amplitude too quickly. It can be minimised by enabling the zero cross setting
+for each volume control. The ZC forces the gain change to occur when the signal
+crosses the zero amplitude line.

From dbc6b6ad767c86907db373e85139b0e975ba7599 Mon Sep 17 00:00:00 2001
From: Richard Purdie <rpurdie@rpsys.net>
Date: Fri, 6 Oct 2006 18:38:03 +0200
Subject: [PATCH 1020/1971] [ALSA] ASoC codecs: generic AC97 support

This patch allows the std Alsa AC97 codec driver to use any AsoC AC97
controller driver. Currently, only HiFi playback and Capture are
supported atm.

Subject: [PATCH 1035/1971] [ALSA] ASoC pxa2xx DMA support

This patch adds pxa2xx ASoC DMA audio support. It's based on
sound/arm/pxa-pcm.c by Nicolas Pitre with the following differences.
o Modified driver structure to use ASoC core PCM callbacks and data
structures.
o Registration with ASoC core.

Subject: [PATCH 1037/1971] [ALSA] ASoC pxa2xx AC97 support

This patch adds pxa2xx AC97 ASoC audio support. It's based on
sound/arm/pxa-ac97 by Nicolas Pitre with the following differences.
 o Modified driver structure to use ASoC core PCM callbacks.
 o Removed AC97 configuration function (all handled in ASoC core)
 o Added and exported ASoC DAI configuration table.
 o Added DMA support for AUX DAC and Mic ADC
 o Separated out AC97 reset into cold and warm reset functions.

From 527541f9a8a83eedb4d732657dbfdcd2c4ca8bb4 Mon Sep 17 00:00:00 2001
From: Liam Girdwood <liam.girdwood@wolfsonmicro.com>
Date: Fri, 13 Oct 2006 12:33:56 +0200
Subject: [PATCH 1044/1971] [ALSA] ASoC DAI capabilities labelling

This patch suggested by Takashi changes the DAI capabilities definitions
in pxa-i2s.c, at91rm9200-i2s.c, wm8731.c, wm8750.c and wm9712.c to use a
label = value style.

Subject: [PATCH 1048/1971] [ALSA] hdspm: Add support for AES32

Add support for AES32. Difference between MADI and AES32 is done
through revision. Master support is not finished for now (RME so-called DDS
feature is not supported yet)

 rev >= 152

Add DDS register support for RME9632 rev >= 152.
This register sets the sample rate for these cards and is required
in addition to the standard control register. It corresponds to a
quartz divisor.

Subject: [PATCH 1055/1971] [ALSA] ASoC: Add support for BCLK based on (Rate *
 Chn * Word Size)

This patch adds support for the DAI BCLK to be generated by multiplying
Rate * Channels * Word Size (RCW).
This now gives 3 options for BCLK clocking and synchronisation :-
 1. BCLK = Rate * x
 2. BCLK = MCLK / x
 3. BCLK = Rate * Chn * Word Size.  (New)
Changes:-
 o Add support for RCW generation of BCLK
 o Update Documentation to include RCW.
 o Update DAI documentation for label = value DAI modes.
 o Add RCW support to wm8731, wm8750 and pxa2xx-i2s drivers.

Subject: [PATCH 1057/1971] [ALSA] ac97 - Suppress power-saving mode on
 non-supporting drivers

Don't enable power-saving mode on drivers that don't support
it.  The supporting drivers set AC97_SCAP_POWER_SAVE to scaps
at creation of ac97 instance.
Currently enable on the following drivers: intel8x0, intel8x0m,
atiixp, atiixp-modem, via82xx and via82xx-modem.
Also, a bit clean up of power-saving stuff:
- Don't create an own workq
- Remove superfluous ifdefs

From 59540fe85924ecb7b9760ab422cffaea0c3ce43a Mon Sep 17 00:00:00 2001
From: Clemens Ladisch <clemens@ladisch.de>
Date: Mon, 6 Nov 2006 09:20:04 +0100
Subject: [PATCH 1062/1971] [ALSA] wavefront: simplify YSS225 register
 initialization

Instead of using a somewhat algorithmic approach of initializing the
YSS225's registers, just use a simple series of port/value pairs.
This makes it easier to later replace or entirely remove the register
data blob.

Subject: [PATCH 1073/1971] [ALSA] Add Conexant audio support to the HD Audio
 driver

This driver adds limited support for the Conexant 5045 and 5047 HD Audio
codecs.  Some issues still need to be resolved.  The code is based
primarily on code from the Analog Devices AD1981 support and the Realtek
ALC260 support.  Some code came from the original code developed by Alex
Pototskiy (see alsa bugtracker 2485).

Subject: [PATCH 1074/1971] [ALSA] hda-codec - Add support for Sony UX-90s

Added the model entry (model=hippo) for Sony UX-90s with ALC262 codec.
Although the device has no SPDIF output, the hippo model adds a
PCM output, but it must be harmless.

Subject: [PATCH 1088/1971] [ALSA] echoaudio, add TLV support

This patch adds TLV support to the echoaudio driver.
All gains are in the range -127dB to +6dB with steps of 1dB, and -128 is
mute. VU-meters levels go from -128 to 0dB. The input gain of the Layla20
ranges from -25dB to +25dB in steps of 0.5dB.

Subject: [PATCH 1095/1971] [ALSA] intel8x0 - Add spdif_aclink option

Added spdif_aclink module option to specify whether the board
has SPDIF over AC-link or a direct connection from the controller
chip.
NForce and ICH4 (or newer) boards may be equipped with SPDIF
through AC97 codec.  In such a case, SPDIF should be handled
as if the old ICH style (the same slot for analog and digital).
A quirk list is added to detect this automatically for known
hardwares.
Corresponds to ALSA bug#2637.

Subject: [PATCH 1096/1971] [ALSA] Update AT91 ASoC driver for 2.6.19 kernel.

Changes were required to support latest AT91 header files.
Also updated to remove AT91RM9200-specific code in the ASoC
platform drivers to support the AT91SAM9260 and AT91SAM9261
chips, but no testing was performed on these chips.

Subject: [PATCH 1099/1971] [ALSA] hda-codec - Use snd_pci_quirk_lookup() for
 board config lookup

Use snd_pci_quirk_lookup() for looking up a board config table.
The config table is sorted in numerical order of PCI SSIDs.

Subject: [PATCH 1102/1971] [ALSA] hda-codec - Make internal speaker work on
 Acer C20x tablets

The following patch creates a new 'Mono speaker' control in alsamixer
when the Realtek 'acer' model is used with hda_intel.  This is needed so
the internal mono speaker (when present) can be controlled.
This new control won't do anything in Acer laptops which are not fitted with
a mono speaker. Acer models which are known to have a mono speaker are the
C20x tablet series but there may be others.  I guess we could define a new
model specifically for Acers with mono speakers but this seems a bit silly
given that such a model will be identical to the normal 'acer' model except
for this added control.
This patch also adds the C20x tablets to the list of PCI ids associated with
the 'acer' model.  This means that owners of C20x machines will no longer
have to supply 'model=acer' when loading hda_intel.

Date: Mon, 4 Dec 2006 18:03:53 +0100
Subject: [PATCH 1106/1971] [ALSA] Current driver does not utilize 44.1kHz high
 quality sampling rate converter.

Following patch will make the driver to use the 44.1kHz SRC automatically
if the pcm source is 44.1kHz signed 16bit stereo.
The SRC is available in YMF754 only.

Subject: [PATCH 1108/1971] [ALSA] emu10k1: Rename the digital optical capture
 control for the Audigy 2 ZS

Notebook.
Digital playback and capture now works, but it is not bit accurate because it
passes through a resampler.
Bit accurate playback and capture will be implemented later via the p17v.

Subject: [PATCH 1110/1971] [ALSA] create device symlink in snd-aoa

create sysfs device symlinks for snd-aoa in /sys/class/sound/controlC0 This
allows hald to recognize the device as sound device.  Furthermore it allows
the desktop user to actually access the sound device nodes.  hald and
related packages will modify the acl attributes.

Subject: [PATCH 1116/1971] [ALSA] Fix the soc code after dhowells workqueue
 changes.

From: Andrew Morton <akpm@osdl.org>
I converted the workqueues to per-device while I was there.  It seems
strange to create a new kernel thread (on each CPU!) and to then only
have a single global work to ever be queued upon it.
Plus without this, I'd have to use the _NAR stuff, gawd help me.
Does that workqueue really need to be per-cpu?
Does that workqueue really need to exist?  Why not use keventd?

simply fully reset it once (and keep the code to take it out of suspend in
case the suspend of the codec chip survives a reset).

Subject: [PATCH 1126/1971] [ALSA] Remove AC97 POP control for STAC9708/11

The STAC9708/11 AC97 codecs implement the PCM Out Path & Mute bit in
the General Purpose register (0x20:F), even though they don't implement
the actual function in the mixer.
Since the alsa tests for the function by toggling the bit and reading
it back to see if it changed, it mistakenly creates a useless control.
This patch explicitly removes the control when the codec is an
STAC9708/11.
I put the check in patch_sigmatel_stac9708_specific(), because I have
an SBLive with this chip on it. I don't know if the STAC9758 or other
codecs also behave this way. If they do, then this check could maybe go
in patch_sigmatel_stac97xx_specific(), or some other more general
function.

Subject: [PATCH 1131/1971] [ALSA] ac97 - fix microphone and line_in selection
 logic

This patch fixes the Microphone and LINE_IN select logic for
Analog Devices surround codecs with shared jacks.  The existing
code can never utilize the shared jacks for Microphone and LINE_IN
due to the reversed jack selection logic.  The patched code
correctly selects the shared jack for input if the 'Channel Mode'
selector does not specify that the jack is to be used for output.
Specifically, in '2ch' mode the Center/LFE jack is used for
microphone input and the Surround jack is used for LINE_IN,
in '4ch' mode the Center/LFE jack is used for microphone input
and the Surround jack is used for output, and in '6ch' mode
both jacks are used for output.

Subject: [PATCH 1133/1971] [ALSA] ac97 - fix malfunctioning mixer controls for
 AD1985

This patch replaces the 'V_REFOUT Enable' mixer switch control
with a listbox control for the AD1985 CODEC.
Previous patch 'AD1888 mixer controls for DC mode' added
controls that were propogated to multiple codecs.  For the
AD1985 codec, the bits VREFH and VREFD function differently,
preventing the 'V_REFOUT Enable' control from setting V_REFOUT
to Hi-Z.
This patch also corrects an issue in which register bits relating
to mixer controls 'Surround Jack Mode' and 'Channel Mode'.
The register bits controlled by these controls were being set
at boot time to states inconsistent with the stored values of
these controls.

From 67e9f4b68c9d1820132c559c0f9b296dafdf631e Mon Sep 17 00:00:00 2001
From: Randy Cushman <rcushman_linux@earthlink.net>
Date: Fri, 22 Dec 2006 12:44:25 +0100
Subject: [PATCH 1134/1971] [ALSA] ac97 - fix various issues with
 AD1986/AD1986A support

Previously, ac97_codec.c was coded to support AD1986 and AD1986A
CODECs using code written for the AD1985 CODEC.  This allowed the
LINE_OUT and HEADPHONE jacks to function properly, however register
differences between the CODECs prevented line and microphone inputs
from functioning.
Specifically, this patch fixes issues with the following mixer
controls:  'V_REFOUT', 'Spread Front to Surround and Center/LFE',
'Exchange Front/Surround', 'Surround Jack Mode', and 'Channel Mode'.
This patch removes the undocumented AD1888 control
'High Pass Filter Enable' and adds the new control
'Exchange Mic/Line In'.

Subject: [PATCH 1138/1971] [ALSA] Add support of the ESI Waveterminal 192M to
 the ice1724 ALSA driver

This patch adds the support of the ESI Waveterminal 192M soundcard
to the ice1724 familly ALSA driver.
It's a semi-professionnal soundcard for home studio : many I/O and
a quality of sound is good, better than consumer cards, but less
musical than professional cards.
It use a Via Envy24ht chipset as ice1724 soundcard, Sigmatel
stac9640 ADC/DAC for the analog I/O as Prodigy192, and Atmel ak4114
for S/PDIF as ESI Julia.
Is working : the 8 analog outputs, the analog inputs 1&2, the mic
input 1, the coaxial & optical digital outputs.

Subject: [PATCH 1152/1971] [ALSA] hda-intel - Don't try to probe invalid
 codecs

Fix the max number of codecs detected by HD-intel (and compatible)
controllers to 3.  Some hardware reports extra bits as if
connected, and the driver gets confused to probe unexisting codecs.

Subject: [PATCH 1153/1971] [ALSA] emu10k1 - Fix ABI for older ld10k1

Fix ABI for older ld10k1.  When no EMU10K1_PVERSION ioctl is issued,
the driver accepts ioctls with the old struct size without TLV information.
Also, changed the struct field to make the conversion easier from the
old to the new structs.

Subject: [PATCH 1172/1971] [ALSA] ASoC force running of delayed PM work at
 suspend() and remove()

This patch fixes a bug whereby the power management delayed work would
never be run at driver suspend() or module remove(). Delayed work would
be created (after audio had finished) with a long delay (~5 secs) and
was sometimes never queued before flush_scheduled_work() was being
called at suspend or module remove. This caused the delayed work to
queued after the module had been removed or after resume.
This patch forces any delayed work to complete by cancelling it (timer
cannot fire and add it to queue later), scheduling it for now and
waiting on it's completion.
This is something I probably would like to add to workqueue.c in the
next merge window, however it's here atm because it can oops.

Subject: [PATCH 1177/1971] [ALSA] hda-intel - Add black/whitelist for
 position_fix option

Some devices are known to require position_fix=1 or 2 to make the
driver working correctly.  Otherwise the sound gets weird effects,
such as stutters.
Now a black/whitelist is introduced to indicate the position_fix
value explicitly for such misbehaving hardwares.  As a first example,
Dell D820 is listed there.  More will come later likely...

Changes:-
 o Removed DAI automatic matching and capabilities structure (struct
snd_soc_dai_mode) and macros.
 o Added DAI operations for codec and CPU interfaces.
 o Removed config_sysclk() function and struct snd_soc_clock_info. No
longer needed as clocking is now configured manually in the machine
drivers. Also removed other clocking data from structures.
 o Updated version to 0.13
 o Added shift to SOC_SINGLE_EXT kcontrol macro.

From cb666e5bd865cc991c0048d6e81581019a141820 Mon Sep 17 00:00:00 2001
From: Liam Girdwood <lg@opensource.wolfsonmicro.com>
Date: Fri, 2 Feb 2007 17:13:49 +0100
Subject: [PATCH 1179/1971] [ALSA] soc - ASoC 0.13 core changes

This patch updates the ASoC core to the new DAI matching and clocking
API in version 0.13
Changes:-
 o Removed DAI capabilities matching code in favour of manual matching
in the machine drivers.
 o Added DAI operations for codec and CPU interfaces.
 o Removed config_sysclk() function and struct snd_soc_clock_info. No
longer needed as clocking is now configured manually in the machine
drivers. Also removed other clocking data from structures.
 o Added machine driver prepare callback.

Subject: [PATCH 1180/1971] [ALSA] soc - 0.13 ASoC DAPM bug fix for unnamed
 streams

This patch fixes a bug whereby an unnamed stream would cause a NULL
pointer ref in snd_soc_dapm_stream_event().

Subject: [PATCH 1181/1971] [ALSA] soc - ASoC 0.13 WM8731 codec

This patch updates the WM8731 codec driver to the new API in ASoC 0.13.
Changes:-
o Removed DAI capabilities matching code in favour of manual matching in
the machine drivers.
o Added DAI operations for codec and CPU interfaces.
o Removed config_sysclk() function and struct snd_soc_clock_info. No
longer needed as clocking is now configured manually in the machine
drivers. Also removed other clocking data from structures.

From 4422b606bc04eab01dd5cb6f8e6dd0608d65bb11 Mon Sep 17 00:00:00 2001
From: Liam Girdwood <lg@opensource.wolfsonmicro.com>
Date: Fri, 2 Feb 2007 17:15:33 +0100
Subject: [PATCH 1182/1971] [ALSA] soc - ASoC 0.13 WM8750 codec driver

This patch updates the WM8750 codec driver to the new API in ASoC 0.13.
Changes:-
o Removed DAI capabilities matching code in favour of manual matching in
the machine drivers.
o Added DAI operations for codec and CPU interfaces.
o Removed config_sysclk() function and struct snd_soc_clock_info. No
longer needed as clocking is now configured manually in the machine
drivers. Also removed other clocking data from structures.

From cbe83b1795feea33803dc89fce18b2b98abbcc9b Mon Sep 17 00:00:00 2001
From: Liam Girdwood <lg@opensource.wolfsonmicro.com>

Subject: [PATCH 1183/1971] [ALSA] soc - ASoC 0.13 WM9712 codec driver

This patch updates the WM9712 codec driver to the new API in ASoC 0.13.
Changes:-
o Removed DAI capabilities matching code in favour of manual matching in
the machine drivers.
o Added DAI operations for codec and CPU interfaces.
o Removed config_sysclk() function and struct snd_soc_clock_info. No
longer needed as clocking is now configured manually in the machine
drivers. Also removed other clocking data from structures.

From 171eb8f81d7b0706c1085d272e4955251ed9f05f Mon Sep 17 00:00:00 2001
From: Frank Mandarino <fmandarino@endrelia.com>
Date: Fri, 2 Feb 2007 17:18:38 +0100
Subject: [PATCH 1186/1971] [ALSA] soc - ASoC 0.13 AT91xxxx I2S

This patch updates the AT91xxxx I2S driver to the new API in ASoC 0.13.
Changes:-
o Removed DAI capabilities matching code in favour of manual matching in
the machine drivers.
o Added DAI operations for codec and CPU interfaces.
o Removed config_sysclk() function and struct snd_soc_clock_info. No
longer needed as clocking is now configured manually in the machine
drivers. Also removed other clocking data from structures.

Subject: [PATCH 1188/1971] [ALSA] soc - ASoC 0.13 AT91xxxx Eti_B1 board
 support

This patch updates the EtI B1 machine driver to the new API in ASoC
0.13.
Changes:-
o  Manually configure DAI hardware format.
o Removed config_sysclk() function. No longer needed as clocking is now
configured manually.

Subject: [PATCH 1189/1971] [ALSA] soc - ASoC 0.13 pxa2xx i2s driver

This patch updates the pxa2xx I2S driver to the new API in ASoC 0.13.
Changes:-
o Removed DAI capabilities matching code in favour of manual matching in
the machine drivers.
o Added DAI operations for codec and CPU interfaces.
o Removed config_sysclk() function and struct snd_soc_clock_info. No
longer needed as clocking is now configured manually in the machine
drivers. Also removed other clocking data from structures.
o Added pxa2xx-i2s.h header

This patch updates the Sharp poodle machine driver to the new API in
ASoC 0.13.
Changes:-
o  Manually configure DAI hardware format.
o Removed config_sysclk() function. No longer needed as clocking is now

Subject: [PATCH 1196/1971] [ALSA] hda-codec - Add ALC861VD/ALC660VD support

o Added ALC861VD support to patch_realtek.c under hda-intel
o Added ALC660VD as a model of 861VD
o Added pci quirks for Asus G1 as well as for two devices found in Realtek's
driver to point at ALC660VD model (3stack-660)
o Added pci quirk for Lenovo 3000 C200 - although untested, it should work
with ALC861VD 3stack model
o Changed preset id = 0x10ec0660 to point at new patch_alc861vd instead of
patch_861
o Organised the list of presets

Subject: [PATCH 1197/1971] [ALSA] usbaudio - Add support for Edirol UA-101

Added support for the Edirol UA-101 (only in high-speed mode) by taking
the quirks for the UA-1000 and change them accordingly. Changes were
made in 'usbaudio.c', 'usbaudio.h', and 'usbquirks.h'
MIDI and recording seem to work perfectly (with JACK), but playback
gives some few glitches. I think that's the mentioned
synchronizing-problem in the UA-1000 quirk ('FIXME: playback must be
synchronized to capture'), so I didn't change that.
ToDo: Adding Mixer-Support for the built-in
control-panel/patch-bay/router.

Subject: [PATCH 1199/1971] [ALSA] snd-ak4114: Fix two array overflows

Fix the handling of the TXCSB registers cache. There was one array
overflow in reg_write() and one in snd_ak4114_reg_write(). Thanks
to David Binderman for reporting the latter.
The second overflow probably doesn't matter much, given that the
function snd_ak4114_reg_write() appears to be never called. I wonder
why it exists and why it is exported.

For some time now, some users of STAC9758 (emu10k1) would have no sound on
their front channels. This can be fixed (at least for me) by unmuting  head
phone volume and setting it to 0dB before removing the 'Front Playback'
control. For details, cf.

Subject: [PATCH 1204/1971] [ALSA] hda-codec - Add support for Fujitsu PI1556
 Realtek ALC880

This patch adds support for the Fujitsu PI1556 laptop.
Issue:  Volume knob on system maxes out lower than alsamixer (0x35 vs 0x40).
Everything else works, and audio quality is good at 0x35.

Subject: [PATCH 1205/1971] [ALSA] aoa i2sbus: Stop Apple i2s DMA gracefully

This fixes the problem of getting extra bytes inserted at the
beginning of a recording when using the Apple i2s interface and DBDMA
controller.  It turns out that we can't just abort the DMA; we have to
let it stop at the end of a command, and then wait for the S7 bit to
be set before turning off the DBDMA controller.  Doing that for
playback doesn't seem to be necessary, but doesn't hurt either.
We use the technique used by the Darwin driver: make each transfer
command branch to a stop command if the S0 status bit is set.  Thus we
can ask the DMA controller to stop at the end of the current command
by setting S0.
The interrupt routine now looks at and clears the status word of the
DBDMA command ring.  This is necessary so it can know when the DBDMA
controller has seen that S0 is set, and so when it should look for the
DBDMA controller being stopped and S7 being set.  This also ended up
simplifying the calculation in i2sbus_pcm_pointer.
Tested on a 15 inch albook.
[Addition by Johannes]
I modified this patch and added the suspend/resume bits to it to get my
powermac into a decent state when playing sound across suspend to disk
that has a different bitrate from what the firmware programs the
hardware to.
I also added the SNDRV_PCM_INFO_JOINT_DUPLEX flag because it seemed the
right thing to do and I was looking at the info stuff.

-ASoC DAI Configuration
-======================
-
-Every CODEC DAI and SoC DAI must have their capabilities defined in order to
-be configured together at runtime when the audio and clocking parameters are
-known. This is achieved by creating an array of struct snd_soc_hw_mode in the
-the CODEC and SoC interface drivers. Each element in the array describes a DAI
-mode and each mode is usually based upon the DAI system clock to sample rate
-ratio (FS).
-
-i.e. 48k sample rate @ 256 FS = sytem clock of 12.288 MHz
-     48000 * 256 = 12288000
-
-The CPU and Codec DAI modes are then ANDed together at runtime to determine the
-rutime DAI configuration for both the Codec and CPU.
-
-When creating a new codec or SoC DAI it's probably best to start of with a few
-sample rates first and then test your interface.
-
-struct snd_soc_dai_mode is defined (in soc.h) as:-
-
-/* SoC DAI mode */
-struct snd_soc_dai_mode {
-	u16 fmt;		/* SND_SOC_DAIFMT_* */
-	u16 tdm;		/* SND_SOC_HWTDM_* */
-	u64 pcmfmt; 	/* SNDRV_PCM_FMTBIT_* */
-	u16 pcmrate;	/* SND_SOC_HWRATE_* */
-	u16 pcmdir:2;	/* SND_SOC_HWDIR_* */
-	u16 flags:8;	/* hw flags */
-	u16 fs;			/* mclk to rate divider */
-	u64 bfs;		/* mclk to bclk dividers */
-	unsigned long priv;		/* private mode data */
-};
-
-fmt:
-----
-This field defines the DAI mode hardware format (e.g. I2S settings) and
-supports the following settings:-
-
- 1) hardware DAI formats
-
-#define SND_SOC_DAIFMT_I2S        (1 << 0)	/* I2S mode */
-#define SND_SOC_DAIFMT_RIGHT_J    (1 << 1)	/* Right justified mode */

-#define SND_SOC_DAIFMT_AC97       (1 << 5)	/* AC97 */
-

-#define SND_SOC_DAIFMT_NB_IF		(1 << 9)	/* normal bclk + inv frm */
-#define SND_SOC_DAIFMT_IB_NF		(1 << 10)	/* invert bclk + nor frm */
-#define SND_SOC_DAIFMT_IB_IF		(1 << 11)	/* invert bclk + frm */
-
- 3) hw clock masters
-    This is wrt the codec, the inverse is true for the interface
-    i.e. if the codec is clk and frm master then the interface is
-    clk and frame slave.
-
-#define SND_SOC_DAIFMT_CBM_CFM		(1 << 12)	/* codec clk & frm master */
-#define SND_SOC_DAIFMT_CBS_CFM		(1 << 13)	/* codec clk slave & frm master */
-#define SND_SOC_DAIFMT_CBM_CFS		(1 << 14)	/* codec clk master & frame slave */
-#define SND_SOC_DAIFMT_CBS_CFS		(1 << 15)	/* codec clk & frm slave */
-
-At least one option from each section must be selected. Multiple selections are
-also supported e.g.
-
- .fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_LEFT_J | SND_SOC_DAIFMT_RIGHT_J | \
-	SND_SOC_DAIFMT_NB_NF | SND_SOC_DAIFMT_NB_IF | SND_SOC_DAIFMT_IB_NF | \
-	SND_SOC_DAIFMT_IB_IF
-
-
-tdm:
-------
-This field defines the Time Division Multiplexing left and right word
-positions for the DAI mode if applicable. Set to SND_SOC_DAITDM_LRDW(0,0) for
-no TDM.
-
-
-pcmfmt:
----------
-The hardware PCM format. This describes the PCM formats supported by the DAI
-mode e.g.
-
- .pcmfmt = SNDRV_PCM_FORMAT_S16_LE | SNDRV_PCM_FORMAT_S20_3LE | \
- 	SNDRV_PCM_FORMAT_S24_3LE
-
-pcmrate:
-----------
-The PCM sample rates supported by the DAI mode. e.g.
-
- .pcmrate = SNDRV_PCM_RATE_8000 | SNDRV_PCM_RATE_11025 | SNDRV_PCM_RATE_16000 | \
-	SNDRV_PCM_RATE_22050 | SNDRV_PCM_RATE_32000 | SNDRV_PCM_RATE_44100 | \
-	SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_88200 | SNDRV_PCM_RATE_96000
-
-
-pcmdir:
----------
-The stream directions supported by this mode. e.g. playback and capture
-
-
-flags:
---------
-The DAI hardware flags supported by the mode.
-
-/* use bfs mclk divider mode (BCLK = MCLK / x) */
-#define SND_SOC_DAI_BFS_DIV		0x1
-/* use bfs rate mulitplier  (BCLK = RATE * x)*/
-#define SND_SOC_DAI_BFS_RATE	0x2
-/* use bfs rcw multiplier (BCLK = RATE * CHN * WORD SIZE) */
-#define SND_SOC_DAI_BFS_RCW		0x4
-/* capture and playback can use different clocks */
-#define SND_SOC_DAI_ASYNC		0x8
-
-NOTE: Bitclock division and mulitiplication modes can be safely matched by the
-core logic.
-
-
-fs:
------
-The FS supported by this DAI mode FS is the ratio between the system clock and
-the sample rate. See above
-
-bfs:
-------
-BFS is the ratio of BCLK to MCLK or the ratio of BCLK to sample rate (this
-depends on the codec or CPU DAI).
-
-The BFS supported by the DAI mode. This can either be the ratio between the
-bitclock (BCLK) and the sample rate OR the ratio between the system clock and
-the sample rate. Depends on the flags above.
-
-priv:
------
-private codec mode data.
-
-
-
-Examples
-========
-
-Note that Codec DAI and CPU DAI examples are interchangeable in these examples
-as long as the bus master is reversed. i.e.
-
-  SND_SOC_DAIFMT_CBM_CFM would become SND_SOC_DAIFMT_CBS_CFS
-  and vice versa.
-
-This applies to all SND_SOC_DAIFMT_CB*_CF*.
-

----------
-
-Simple codec that only runs at 8k & 48k @ 256FS in master mode, can generate a

-ASoC Clocking
--------------
 
-The ASoC core determines the clocking for each particular configuration at
-runtime. This is to allow for dynamic audio clocking wereby the audio clock is
-variable and depends on the system state or device usage scenario. i.e. a voice
-call requires slower clocks (and hence less power) than MP3 playback.
 
-ASoC will call the config_sysclock() function for the target machine during the
-audio parameters configuration. The function is responsible for then clocking
-the machine audio subsytem and returning the audio clock speed to the core.
-This function should also call the codec and cpu DAI clock_config() functions
-to configure their respective internal clocking if required.
-
-
-ASoC Clocking Control Flow
---------------------------
-
-The ASoC core will call the machine drivers config_sysclock() when most of the
-DAI capabilities are known. The machine driver is then responsible for calling
-the codec and/or CPU DAI drivers with the selected capabilities and the current
-MCLK. Note that the machine driver is also resonsible for setting the MCLK (and
-enabling it).
-
-   (1) Match Codec and CPU DAI capabilities. At this point we have
-       matched the majority of the DAI fields and now need to make sure this
-       mode is currently clockable.
-
-   (2) machine->config_sysclk() is now called with the matched DAI FS, sample
-       rate and BCLK master. This function then gets/sets the current audio
-       clock (depening on usage) and calls the codec and CPUI DAI drivers with
-       the FS, rate, BCLK master and MCLK.
-
-   (3) Codec/CPU DAI config_sysclock(). This function checks that the FS, rate,
-       BCLK master and MCLK are acceptable for the codec or CPU DAI. It also
-       sets the DAI internal state to work with said clocks.
-
-The config_sysclk() functions for CPU, codec and machine should return the MCLK
-on success and 0 on failure.
-

 ASoC Codec driver breakdown
 ===========================
 
-1 - Digital Audio Interface (DAI) description
----------------------------------------------
-The DAI is a digital audio data transfer link between the codec and host SoC
-CPU. It typically has data transfer capabilities in both directions
-(playback and capture) and can run at a variety of different speeds.
-Supported interfaces currently include AC97, I2S and generic PCM style links.
-Please read DAI.txt for implementation information.
-
-
-2 - Digital Audio Interface (DAI) configuration
------------------------------------------------
-DAI configuration is handled by the codec_pcm_prepare function and is
-responsible for configuring and starting the DAI on the codec. This can be
-called multiple times and is atomic. It can access the runtime parameters.
-
-This usually consists of a large function with numerous switch statements to
-set up each configuration option. These options are set by the core at runtime.
-
-
-3 - Codec PCM's
----------------
-Each codec must have it's PCM's defined. This defines the number of channels,
-stream names, callbacks and codec name. It is also used to register the DAI
-with the ASoC core. The PCM structure also associates the DAI capabilities with
-the ALSA PCM.

+Each codec driver must have a struct snd_soc_codec_dai to define it's DAI and
+PCM's capablities and operations. This struct is exported so that it can be

Subject: [PATCH 1212/1971] [AVR32] ext int fixes

Bugfixes for external irq handler set_irq_type():

 - If set_irq_type() can't set the type, don't change anything!

 - It's not OK to change the flow handler as part of set_irq_type(),
   among other issues that violates spinlock rules.  Instead, we can
   call the relevant handler when we demux the external interrupts.

 - The external irq demux has no need to grab the spinlock.  And in
   fact grabbing it that way was wrong, since that code might be
   pre-empted by an irq at a different priority level, and that code
   might then have tried to grab that spinlock...

Subject: [PATCH 1218/1971] [AVR32] Introduce at32_reserve_pin()

at32_reserve_pin() can be used for reserving portmux pins without
altering their configuration. Useful for e.g. SDRAM pins where we
really don't want to change the bootloader-provided configuration.

Subject: [PATCH 1219/1971] [AVR32] Add PIOE device and reserve SDRAM pins

The PIOE device was left out before because it muxes SDRAM pins (and
is therefore a bit dangerous to mess with) and because no existing
drivers had any use for it.

It is needed for CompactFlash, however, and now that we have a way
to protect the SDRAM pins, it can be safely added.

Subject: [PATCH 1222/1971] [AVR32] ssize_t should be long, not int

Since size_t is defined as unsigned long, ssize_t ought to be long
and not int. It could have been the other way around, but gcc defines
size_t as unsigned long, so this is correct.

This fixes a couple of printk format warnings.

-What:	find_trylock_page
-When:	January 2007
-Why:	The interface no longer has any callers left in the kernel. It
-	is an odd interface (compared with other find_*_page functions), in
-	that it does not take a refcount to the page, only the page lock.
-	It should be replaced with find_get_page or find_lock_page if possible.

-	cannot cleanly use something else.

Subject: [PATCH 1226/1971] [TC] MIPS: TURBOchannel update to the driver model

This is a set of changes to convert support for the TURBOchannel bus to the
driver model.  It implements the usual set of calls similar to what other bus
drivers have: tc_register_driver(), tc_unregister_driver(), etc.  All the
platform-specific bits have been removed and headers from asm-mips/dec/ have
been merged into linux/tc.h, which should be included by drivers.

Subject: [PATCH 1228/1971] [TC] TURBOchannel support for the DECstation

This is the platform-specific part of TURBOchannel bus support for the
DECstation.  It implements determining whether the bus is actually there,
getting bus parameters, IRQ assignments for devices and protected accesses
to possibly unoccupied slots that may trigger bus error exceptions.

Subject: [PATCH 1229/1971] [TC] defxx: TURBOchannel support

This is a set of changes to add TURBOchannel support to the defxx driver.  As
at this point the EISA support in the driver has become the only not having
been converted to the driver model, I took the opportunity to convert it as
well.  Plus support for MMIO in addition to PIO operation as TURBOchannel
requires it anyway.

Subject: [PATCH 1230/1971] [TC] mips: pmag-ba-fb: Convert to the driver model

This is a set of changes to convert the driver to the driver model.  As a
side-effect the driver now supports building as a module.

From 4df4db5c6c6daeb10a8693d09ce872bce8cd84e6 Mon Sep 17 00:00:00 2001
From: "Maciej W. Rozycki" <macro@linux-mips.org>
Date: Mon, 5 Feb 2007 16:28:29 -0800
Subject: [PATCH 1231/1971] [TC] dec_esp: Driver model for the PMAZ-A

This is a set of changes that converts the PMAZ-A support to the driver model.

The use of the driver model required switching to the hotplug SCSI
initialization model, which in turn required a change to the core NCR53C9x
driver.  I decided not to break all the frontend drivers and introduced an
additional parameter for esp_allocate() to select between the old and the new
model.  I hope this is OK, but I would be fine with converting NCR53C9x to the
new model unconditionally as long as I do not have to fix all the other
frontends (OK, perhaps I could do some of them ;-) ).

Subject: [PATCH 1233/1971] [EISA] EISA registration with !CONFIG_EISA

This is a change for the EISA bus support to permit drivers to call
un/registration functions even if EISA support has not been enabled.  This is
similar to what PCI (and now TC) does and reduces the need for #ifdef clutter.

Date: Fri, 9 Feb 2007 17:08:58 +0000
Subject: [PATCH 1244/1971] [APM] MIPS: Convert to use shared APM emulation.

Also convert to use generic kernel/power/Kconfig to make the use of the
shared APM emulation possible.

-	  APM is a BIOS specification for saving power using several different
-	  techniques. This is mostly useful for battery powered systems with
-	  APM compliant BIOSes. If you say Y here, the system time will be
-	  reset after a RESUME operation, the /proc/apm device will provide
-	  battery status information, and user-space programs will receive
-	  notification of APM "events" (e.g. battery status change).
-
-	  In order to use APM, you will need supporting software. For location
-	  and more information, read <file:Documentation/pm.txt> and the
-	  Battery Powered Linux mini-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>.
-
-	  This driver does not spin down disk drives (see the hdparm(8)
-	  manpage ("man 8 hdparm") for that), and it doesn't turn off
-	  VESA-compliant "green" monitors.
-
-	  Generally, if you don't have a battery in your machine, there isn't
-	  much point in using this driver and you should say N. If you get
-	  random kernel OOPSes or reboots that don't seem to be related to
-	  anything, try disabling/enabling this option (or disabling/enabling
-	  APM in your BIOS).

Subject: [PATCH 1255/1971] [PATCH] kill eth_io_copy_and_sum()

On all targets that sucker boils down to memcpy_fromio(sbk->data, from, len).
The function name is highly misguiding (it _never_ does any checksums), the
last argument is just a noise and simply expanding the call to memcpy_fromio()
gives shorter and more readable source.  For a lot of reasons it has almost
no remaining users, so it's better to just outright kill it.

Subject: [PATCH 1274/1971] [PATCH] rtc-pcf8563: detect polarity of century bit
 automatically

The usage of the century bit was inverted on 2.6.19 following to PCF8563's
description, but it was not match to usage suggested by RTC8564's
datasheet.  Anyway what MO_C=1 means can vary on each platform.  This patch
is to detect its polarity in get_datetime routine.  The default value of
c_polarity is 0 (MO_C=1 means 19xx) so that this patch does not change
current behavior even if get_datetime was not called before set_datetime.

Subject: [PATCH 1275/1971] [PATCH] ufs: restore back support of openstep

This is a fix of regression, which triggered by ~2.6.16.

Patch with name ufs-directory-and-page-cache-from-blocks-to-pages.patch: in
additional to conversation from block to page cache mechanism added new
checks of directory integrity, one of them that directory entry do not
across directory chunks.

But some kinds of UFS: OpenStep UFS and Apple UFS (looks like these are the
same filesystems) have different directory chunk size, then common
UFSes(BSD and Solaris UFS).

So this patch adds ability to works with variable size of directory chunks,
and set it for ufstype=openstep to right size.

Tested on darwin ufs.

Subject: [PATCH 1276/1971] [PATCH] hugetlb: preserve hugetlb pte dirty state

__unmap_hugepage_range() is buggy that it does not preserve dirty state of
huge_pte when unmapping hugepage range.  It causes data corruption in the
event of dop_caches being used by sys admin.  For example, an application
creates a hugetlb file, modify pages, then unmap it.  While leaving the
hugetlb file alive, comes along sys admin doing a "echo 3 >
/proc/sys/vm/drop_caches".

drop_pagecache_sb() will happily free all pages that aren't marked dirty if
there are no active mapping.  Later when application remaps the hugetlb
file back and all data are gone, triggering catastrophic flip over on
application.

Not only that, the internal resv_huge_pages count will also get all messed
up.  Fix it up by marking page dirty appropriately.

Subject: [PATCH 1277/1971] [PATCH] md: fix various bugs with aligned reads in
 RAID5

It is possible for raid5 to be sent a bio that is too big for an underlying
device.  So if it is a READ that we pass stright down to a device, it will
fail and confuse RAID5.

So in 'chunk_aligned_read' we check that the bio fits within the parameters
for the target device and if it doesn't fit, fall back on reading through
the stripe cache and making lots of one-page requests.

Note that this is the earliest time we can check against the device because
earlier we don't have a lock on the device, so it could change underneath
us.

Also, the code for handling a retry through the cache when a read fails has
not been tested and was badly broken.  This patch fixes that code.

Subject: [PATCH 1278/1971] [PATCH] knfsd: fix a race in closing NFSd
 connections

If you lose this race, it can iput a socket inode twice and you get a BUG
in fs/inode.c

When I added the option for user-space to close a socket, I added some
cruft to svc_delete_socket so that I could call that function when closing
a socket per user-space request.

This was the wrong thing to do.  I should have just set SK_CLOSE and let
normal mechanisms do the work.

Not only wrong, but buggy.  The locking is all wrong and it openned up a
race where-by a socket could be closed twice.

So this patch:
  Introduces svc_close_socket which sets SK_CLOSE then either leave
  the close up to a thread, or calls svc_delete_socket if it can
  get SK_BUSY.

  Adds a bias to sk_busy which is removed when SK_DEAD is set,
  This avoid races around shutting down the socket.

  Changes several 'spin_lock' to 'spin_lock_bh' where the _bh
  was missing.

Subject: [PATCH 1279/1971] [PATCH] md: avoid possible BUG_ON in md bitmap
 handling

md/bitmap tracks how many active write requests are pending on blocks
associated with each bit in the bitmap, so that it knows when it can clear
the bit (when count hits zero).

The counter has 14 bits of space, so if there are ever more than 16383, we
cannot cope.

Currently the code just calles BUG_ON as "all" drivers have request queue
limits much smaller than this.

However is seems that some don't.  Apparently some multipath configurations
can allow more than 16383 concurrent write requests.

So, in this unlikely situation, instead of calling BUG_ON we now wait
for the count to drop down a bit.  This requires a new wait_queue_head,
some waiting code, and a wakeup call.

Tested by limiting the counter to 20 instead of 16383 (writes go a lot slower
in that case...).

Subject: [PATCH 1283/1971] [PATCH] Add install_special_mapping

This patch adds a utility function install_special_mapping, for creating a
special vma using a fixed set of preallocated pages as backing, such as for a
vDSO.  This consolidates some nearly identical code used for vDSO mapping
reimplemented for different architectures.

Subject: [PATCH 1288/1971] [PATCH] kbuild: more Makefile cleanups

This adds the remaining changes which should have been part of the
review process.

 - the define command is inappropriate (it's primarily for rule
   definitions)
 - execute commands in the current dir as all other commands
 - .*.tmp (but not .*.null) files are also removed up by "make clean"
 - printf has other side effects, just use "echo -e"
 - proper quoting
 - proper indentation

Subject: [PATCH 1293/1971] [PATCH] uclinux: correctly remap bin_fmtflat exe
 allocated mem regions

remap() the region we get from mmap() to mark the fact that we are
using all of the available slack space. Any slack space is used
to form a simple brk region, and potentially more stack space than
requested at load time.

Any searches of the vma chain may well fail looking for
stack (and especially arg) addresses if the remaping is not done.
The simplest example is /proc/<pid>/cmdline, since the args
are pretty much always at the top of the data/bss/stack region.

Subject: [PATCH 1296/1971] [PATCH] sata_sis: support SiS966/966L

The SiS966/966L has different PCI-IDs for native mode and AHCI mode.
The SiS966 supports four SATA ports only in native mode.

Added additional PCI-ID 0x0183 for SiS965/965L.

this patch is based on the code from David Wang from SiS Corporation published on SiS Website.

Subject: [PATCH 1297/1971] [PATCH] pata_it8213: Add new driver for the IT8213
 card

Add a driver for the IT8213 which is a single channel ICH-ish PATA
controller.  As it is very different to the IT8211/2 it gets its own
driver.  There is a legacy drivers/ide driver also available and I'll post
that once I get time to test it all out (probably early January).  If
anyone else needs the drivers/ide driver and wants to do the merge for
drivers/ide (Bart ??) then I'll forward it.

From: Mikael Pettersson <mikpe@it.uu.se>
Date: Tue, 9 Jan 2007 10:50:27 +0100
Subject: [PATCH 1302/1971] sata_promise: TX2plus PATA support

This patch implements a simple way of setting up per-port
flags on the SATA+PATA Promise TX2plus chips, which is a
prerequisite for supporting the PATA port on those chips.

It is based on the observation that ap->flags isn't really
used until after ->port_start() has been invoked. So it
places the "exceptional" per-port flags array in the driver's
private host structure, and uses it in ->port_start() to
finalise the port's flags.

This patch obsoletes the #promise-sata-pata branch included
in the #all branch.

Subject: [PATCH 1303/1971] sata_promise: ATAPI support

This patch adds ATAPI support to the sata_promise driver.
This has been tested on both first- and second-generation
chips (20378 and 20575), and with both SATAPI and PATAPI
devices. CD-writing works.

SATAPI DMA works on second-generation chips, but on
first-generation chips SATAPI is limited to PIO due
to what appears to be HW limitations.
PATAPI DMA works on both first- and second-generation
chips, but requires the separate PATA support patch
before it can be used on TX2plus chips.

The functional changes to the driver are:
- remove ATA_FLAG_NO_ATAPI from PDC_COMMON_FLAGS
- add ->check_atapi_dma() operation to enable DMA for bulk data
  transfers but force PIO for other ATAPI commands; this filter
  is from Promise's driver and largely matches pata_pdc207x.c
- use a more restrictive ->check_atapi_dma() on first-generation
  chips to force SATAPI to always use PIO
- add handling of ATAPI protocols to pdc_qc_prep(), pdc_host_intr(),
  and pdc_qc_issue_prot(): ATAPI_DMA is handled by the driver
  while non-DMA protocols are handed over to libata generic code
- add pdc_issue_atapi_pkt_cmd() to handle the initial steps in
  issuing ATAPI DMA commands before sending the actual CDB;
  this procedure was ported from Promise's driver

Subject: [PATCH 1308/1971] libata-sff: Don't try and activate channels which
 are not in use

An ATA controller in native mode may have one or more channels disabled
and not assigned resources. In that case the existing code crashes trying
to access I/O ports 0-7.

Add the neccessary check.

The AHCI set up is handled properly along with the other bits in the
JMICRON quirk. Remove the code whacking it in ahci.c as its un-needed and
also blindly fiddles with bits it doesn't own.

From a0cf733b333eeeafb7324e2897448006c693c26c Mon Sep 17 00:00:00 2001
From: Tejun Heo <htejun@gmail.com>
Date: Tue, 2 Jan 2007 20:18:49 +0900
Subject: [PATCH 1312/1971] libata: straighten out ATA_ID_* constants

* Kill _OFS suffixes in ATA_ID_{SERNO|FW_REV|PROD}_OFS for consistency
  with other ATA_ID_* constants.

* Kill ATA_SERNO_LEN

* Add and use ATA_ID_SERNO_LEN, ATA_ID_FW_REV_LEN and ATA_ID_PROD_LEN.
  This change also makes ata_device_blacklisted() use proper length
  for fwrev.

Subject: [PATCH 1313/1971] libata: use ata_id_c_string()

There were several places where ATA ID strings are manually terminated
and in some places possibly unterminated strings were passed to string
functions which don't limit length like strstr().  This patch converts
all of them over to ata_id_c_string().

Subject: [PATCH 1314/1971] libata: handle pci_enable_device() failure while
 resuming

Handle pci_enable_device() failure while resuming.  This patch kills
the "ignoring return value of 'pci_enable_device'" warning message and
propagates __must_check through ata_pci_device_do_resume().

Subject: [PATCH 1317/1971] libata: kill qc->nsect and cursect

libata used two separate sets of variables to record request size and
current offset for ATA and ATAPI.  This is confusing and fragile.
This patch replaces qc->nsect/cursect with qc->nbytes/curbytes and
kills them.  Also, ata_pio_sector() is updated to use bytes for
qc->cursg_ofs instead of sectors.  The field used to be used in bytes
for ATAPI and in sectors for ATA.

Subject: [PATCH 1318/1971] sata_inic162x: finally, driver for initio 162x SATA
 controllers, take #2

Driver for Initio 162x SATA controllers.  ATA r/w, ATAPI r, hotplug
and suspend/resume work.  ATAPI w (recording, that is) broken.  Feel
free to fix it, but be warned, this controller is weird.

Subject: [PATCH 1319/1971] sata_promise: ATAPI cleanup

Here's a cleanup for yesterday's sata_promise ATAPI patch:
- add and use a symbolic constant for the altstatus register
- check return status from ata_busy_wait()
- add missing newline in a warning printk()
- update comment in pdc_issue_atapi_pkt_cmd() to clarify
  that the maybe-wait-for-INT issue cannot occur in the
  current driver, but may occur if the driver starts issuing
  ATAPI non-DMA commands as PDC packets

Subject: [PATCH 1320/1971] sata_promise: issue ATAPI commands as normal
 packets

This patch (against libata #upstream + the ATAPI cleanup patch)
reimplements sata_promise's ATAPI support to format ATAPI DMA
commands as normal packets, and to issue them via the hardware's
normal packet machinery.

It turns out that the only reason for issuing ATAPI DMA
commands via the pdc_issue_atapi_pkt_cmd() procedure was to
perform two interrupt-fiddling steps for ATA_DFLAG_CDB_INTR
devices. But these steps aren't needed because sata_promise
sets ATA_FLAG_PIO_POLLING, which disables DMA for those devices.
The remaining steps can easily be done in ATA taskfile packets.

Concrete changes:
- pdc_atapi_dma_pkt() is extended to program all packet setup
  steps, and not just contain the CDB; the sequence of steps
  exactly mirrors what pdc_issue_atapi_pkt_cmd() did
- pdc_atapi_dma_pkt() needed more parameters: simplify it by
  just passing 'qc' and having it extract the data it needs
- pdc_issue_atai_pkt_cmd() and its two helper procedures
  pdc_wait_for_drq() and pdc_wait_on_busy() are removed

Tested on first- and second-generation chips, SATAPI and PATAPI,
with no observable regressions.

Subject: [PATCH 1321/1971] sata_promise: handle ATAPI_NODATA ourselves

This patch extends sata_promise to handle ATAPI_NODATA
commands internally. However, commands destined to
ATA_DFLAG_CDB_INTR devices are excluded from this and
continue to be returned to libata.

Concrete changes:
- pdc_atapi_dma_pkt() is renamed to pdc_atapi_pkt(), and is
  extended to set up correct headers for NODATA packets
- pdc_qc_prep() calls pdc_atapi_pkt() for ATAPI_NODATA
- pdc_host_intr() handles ATAPI_NODATA
- pdc_qc_issue_prot() sends ATAPI_NODATA packets via the
  chip's packet mechanism, except for CDB_INTR devices

Tested on first- and second-generation chips, SATAPI and PATAPI,
with no observable regressions.

This I believe completes the PIIX range of support for libata

This adds the table entries needed for the PIIX3, both a new PCI
identifier and a new mode list. It also fixes an erroneous access to PCI
configuration 0x48 on non UDMA capable chips.

Subject: [PATCH 1327/1971] sata_sis: Support for PATA supports

This is quick rework of the patch Uwe proposed but using Kconfig not
ifdefs and user selection to sort out PATA support. Instead of ifdefs and
requiring the user to select both drivers the SATA driver selects the
PATA one.

For neatness I've also moved the extern into the function that uses it.

Subject: [PATCH 1329/1971] devres: device resource management

Implement device resource management, in short, devres.  A device
driver can allocate arbirary size of devres data which is associated
with a release function.  On driver detach, release function is
invoked on the devres data, then, devres data is freed.

devreses are typed by associated release functions.  Some devreses are
better represented by single instance of the type while others need
multiple instances sharing the same release function.  Both usages are
supported.

devreses can be grouped using devres group such that a device driver
can easily release acquired resources halfway through initialization
or selectively release resources (e.g. resources for port 1 out of 4
ports).

This patch adds devres core including documentation and the following
managed interfaces.

* alloc/free	: devm_kzalloc(), devm_kzfree()
* IO region	: devm_request_region(), devm_release_region()
* IRQ		: devm_request_irq(), devm_free_irq()
* DMA		: dmam_alloc_coherent(), dmam_free_coherent(),
		  dmam_declare_coherent_memory(), dmam_pool_create(),
		  dmam_pool_destroy()
* PCI		: pcim_enable_device(), pcim_pin_device(), pci_is_managed()
* iomap		: devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(),
		  devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(),
		  pcim_iomap(), pcim_iounmap()

+Devres - Managed Device Resource
+================================
+
+Tejun Heo	<teheo@suse.de>
+
+First draft	10 January 2007
+
+
+1. Intro			: Huh? Devres?
+2. Devres			: Devres in a nutshell
+3. Devres Group			: Group devres'es and release them together
+4. Details			: Life time rules, calling context, ...
+5. Overhead			: How much do we have to pay for this?
+6. List of managed interfaces	: Currently implemented managed interfaces
+
+
+  1. Intro
+  --------
+
+devres came up while trying to convert libata to use iomap.  Each
+iomapped address should be kept and unmapped on driver detach.  For
+example, a plain SFF ATA controller (that is, good old PCI IDE) in
+native mode makes use of 5 PCI BARs and all of them should be
+maintained.
+
+As with many other device drivers, libata low level drivers have
+sufficient bugs in ->remove and ->probe failure path.  Well, yes,
+that's probably because libata low level driver developers are lazy
+bunch, but aren't all low level driver developers?  After spending a
+day fiddling with braindamaged hardware with no document or
+braindamaged document, if it's finally working, well, it's working.
+
+For one reason or another, low level drivers don't receive as much
+attention or testing as core code, and bugs on driver detach or
+initilaization failure doesn't happen often enough to be noticeable.
+Init failure path is worse because it's much less travelled while
+needs to handle multiple entry points.
+
+So, many low level drivers end up leaking resources on driver detach
+and having half broken failure path implementation in ->probe() which
+would leak resources or even cause oops when failure occurs.  iomap
+adds more to this mix.  So do msi and msix.
+
+
+  2. Devres
+  ---------
+
+devres is basically linked list of arbitrarily sized memory areas
+associated with a struct device.  Each devres entry is associated with
+a release function.  A devres can be released in several ways.  No
+matter what, all devres entries are released on driver detach.  On
+release, the associated release function is invoked and then the
+devres entry is freed.
+
+Managed interface is created for resources commonly used by device
+drivers using devres.  For example, coherent DMA memory is acquired
+using dma_alloc_coherent().  The managed version is called
+dmam_alloc_coherent().  It is identical to dma_alloc_coherent() except
+for the DMA memory allocated using it is managed and will be
+automatically released on driver detach.  Implementation looks like
+the following.
+
+  struct dma_devres {
+	size_t		size;
+	void		*vaddr;
+	dma_addr_t	dma_handle;
+  };
+
+  static void dmam_coherent_release(struct device *dev, void *res)
+  {
+	struct dma_devres *this = res;
+
+	dma_free_coherent(dev, this->size, this->vaddr, this->dma_handle);
+  }
+
+  dmam_alloc_coherent(dev, size, dma_handle, gfp)
+  {
+	struct dma_devres *dr;
+	void *vaddr;
+
+	dr = devres_alloc(dmam_coherent_release, sizeof(*dr), gfp);
+	...
+
+	/* alloc DMA memory as usual */
+	vaddr = dma_alloc_coherent(...);
+	...
+
+	/* record size, vaddr, dma_handle in dr */
+	dr->vaddr = vaddr;
+	...
+
+	devres_add(dev, dr);
+
+	return vaddr;
+  }
+
+If a driver uses dmam_alloc_coherent(), the area is guaranteed to be
+freed whether initialization fails half-way or the device gets
+detached.  If most resources are acquired using managed interface, a
+driver can have much simpler init and exit code.  Init path basically
+looks like the following.
+
+  my_init_one()
+  {
+	struct mydev *d;
+
+	d = devm_kzalloc(dev, sizeof(*d), GFP_KERNEL);
+	if (!d)
+		return -ENOMEM;
+
+	d->ring = dmam_alloc_coherent(...);
+	if (!d->ring)
+		return -ENOMEM;
+
+	if (check something)
+		return -EINVAL;
+	...
+
+	return register_to_upper_layer(d);
+  }
+
+And exit path,
+
+  my_remove_one()
+  {
+	unregister_from_upper_layer(d);
+	shutdown_my_hardware();
+  }
+
+As shown above, low level drivers can be simplified a lot by using
+devres.  Complexity is shifted from less maintained low level drivers
+to better maintained higher layer.  Also, as init failure path is
+shared with exit path, both can get more testing.
+
+
+  3. Devres group
+  ---------------
+
+Devres entries can be grouped using devres group.  When a group is
+released, all contained normal devres entries and properly nested
+groups are released.  One usage is to rollback series of acquired
+resources on failure.  For example,
+
+  if (!devres_open_group(dev, NULL, GFP_KERNEL))
+	return -ENOMEM;
+
+  acquire A;
+  if (failed)
+	goto err;
+
+  acquire B;
+  if (failed)
+	goto err;
+  ...
+
+  devres_remove_group(dev, NULL);
+  return 0;
+
+ err:
+  devres_release_group(dev, NULL);
+  return err_code;
+
+As resource acquision failure usually means probe failure, constructs
+like above are usually useful in midlayer driver (e.g. libata core
+layer) where interface function shouldn't have side effect on failure.
+For LLDs, just returning error code suffices in most cases.
+
+Each group is identified by void *id.  It can either be explicitly
+specified by @id argument to devres_open_group() or automatically
+created by passing NULL as @id as in the above example.  In both
+cases, devres_open_group() returns the group's id.  The returned id
+can be passed to other devres functions to select the target group.
+If NULL is given to those functions, the latest open group is
+selected.
+
+For example, you can do something like the following.
+
+  int my_midlayer_create_something()
+  {
+	if (!devres_open_group(dev, my_midlayer_create_something, GFP_KERNEL))
+		return -ENOMEM;
+
+	...
+
+	devres_close_group(dev, my_midlayer_something);
+	return 0;
+  }
+
+  void my_midlayer_destroy_something()
+  {
+	devres_release_group(dev, my_midlayer_create_soemthing);
+  }
+
+
+  4. Details
+  ----------
+
+Lifetime of a devres entry begins on devres allocation and finishes
+when it is released or destroyed (removed and freed) - no reference
+counting.
+
+devres core guarantees atomicity to all basic devres operations and
+has support for single-instance devres types (atomic
+lookup-and-add-if-not-found).  Other than that, synchronizing
+concurrent accesses to allocated devres data is caller's
+responsibility.  This is usually non-issue because bus ops and
+resource allocations already do the job.
+
+For an example of single-instance devres type, read pcim_iomap_table()
+in lib/iomap.c.
+
+All devres interface functions can be called without context if the
+right gfp mask is given.
+
+
+  5. Overhead
+  -----------
+
+Each devres bookkeeping info is allocated together with requested data
+area.  With debug option turned off, bookkeeping info occupies 16
+bytes on 32bit machines and 24 bytes on 64bit (three pointers rounded
+up to ull alignment).  If singly linked list is used, it can be
+reduced to two pointers (8 bytes on 32bit, 16 bytes on 64bit).
+
+Each devres group occupies 8 pointers.  It can be reduced to 6 if
+singly linked list is used.
+
+Memory space overhead on ahci controller with two ports is between 300
+and 400 bytes on 32bit machine after naive conversion (we can
+certainly invest a bit more effort into libata core layer).
+
+
+  6. List of managed interfaces

Subject: [PATCH 1330/1971] libata: implement ata_host_detach()

Implement ata_host_detach() which calls ata_port_detach() for each
port in the host and export it.  ata_port_detach() is now internal and
thus un-exported.  ata_host_detach() will be used as the 'deregister
from libata layer' function after devres conversion.

Subject: [PATCH 1331/1971] libata: update libata core layer to use devres

Update libata core layer to use devres.

* ata_device_add() acquires all resources in managed mode.

* ata_host is allocated as devres associated with ata_host_release.

* Port attached status is handled as devres associated with
  ata_host_attach_release().

* Initialization failure and host removal is handedl by releasing
  devres group.

* Except for ata_scsi_release() removal, LLD interface remains the
  same.  Some functions use hacky is_managed test to support both
  managed and unmanaged devices.  These will go away once all LLDs are
  updated to use devres.

From 24dc5f33ea4b504cfbd23fa159a4cacba8e4d800 Mon Sep 17 00:00:00 2001
From: Tejun Heo <htejun@gmail.com>

Subject: [PATCH 1332/1971] libata: update libata LLDs to use devres

Update libata LLDs to use devres.  Core layer is already converted to
support managed LLDs.  This patch simplifies initialization and fixes
many resource related bugs in init failure and detach path.  For
example, all converted drivers now handle ata_device_add() failure
gracefully without excessive resource rollback code.

As most resources are released automatically on driver detach, many
drivers don't need or can do with much simpler ->{port|host}_stop().
In general, stop callbacks are need iff port or host needs to be given
commands to shut it down.  Note that freezing is enough in many cases
and ports are automatically frozen before being detached.

Subject: [PATCH 1334/1971] devres: implement pcim_iomap_regions()

Implement pcim_iomap_regions().  This function takes mask of BARs to
request and iomap.  No BAR should have length of zero.  BARs are
iomapped using pcim_iomap_table().

Subject: [PATCH 1338/1971] libata: convert to iomap

Convert libata core layer and LLDs to use iomap.

* managed iomap is used.  Pointer to pcim_iomap_table() is cached at
  host->iomap and used through out LLDs.  This basically replaces
  host->mmio_base.

* if possible, pcim_iomap_regions() is used

Most iomap operation conversions are taken from Jeff Garzik
<jgarzik@pobox.com>'s iomap branch.

Fix the wrong "compatible" PIO mode choices: MWDMA0 has 480 ns cycle while PIO1
only has 383 ns cycle, and MWDMA2 timings matchs those of PIO4 exactly.

Subject: [PATCH 1344/1971] libata: add 150ms between completion of hardreset
 and status checking

Follow the old SRST rule and delay 150ms between completion of
hardreset and status checking.  Debouncing delay should usually cover
this but debounce duration could be shorter than 150ms under certain
circumstances.

Usefulness depends on host controller implementation but it can't hurt
and serves as a reminder that 2s delay for GoVault should also be
added here.

Subject: [PATCH 1350/1971] (2.6.20) pata_mpiix: probing cleanup (resend)

MPIIX has only single channel IDE which can be configured for either primary or
secondary legacy I/O ports and IRQ.  So, get rid of the unneeded second probe
entry in mpiix_init_one() and of the invalid (but unused anyway) enable bits in
mpiix_pre_reset().

Warning: this cleanup has only been compile-tested...

Subject: [PATCH 1351/1971] sata_nv: cleanup ADMA error handling

This cleans up a few issues with the error handling in sata_nv in ADMA mode
to make it more consistent with other NCQ-capable drivers like ahci and
sata_sil24:

- When a command failed, we would effectively set AC_ERR_DEV on the
  queued command always.  In the case of NCQ commands this prevents libata
  from doing a log page query to determine the details of the failed
  command, since it thinks we've already analyzed.  Just set flags in the
  port ehi->err_mask, then freeze or abort and let libata figure out what
  went wrong.

- The code handled NV_ADMA_STAT_CPBERR as a "really bad error" which
  caused it to set error flags on every queued command.  I don't know
  exactly what this flag means (no docs, grr!) but from what I can guess
  from the standard ADMA spec, it just means that one or more of the CPBs
  had an error, so we just need to go through and do our normal checks in
  this case.

- In the error_handler function the code would always dump the state of
  all the CPBs.  This output seems redundant at this point since libata
  already dumps the state of all active commands on errors (and it also
  triggers at times when it shouldn't, like when suspending).  Take this
  out.

Subject: [PATCH 1352/1971] sata_nv: use ADMA for NODATA commands

Some problems showed up recently with cache flush commands timing out on
sata_nv.  Previously these commands were always handled by transitioning to
legacy mode from ADMA mode first.  The timeout problem was worked around
already by a change to the interrupt handling code for legacy mode, but for
non-data commands like these it appears we can handle them in ADMA mode, so
the switch to legacy mode is not needed.

This patch changes the behavior so that we use ADMA mode to submit
interrupt-driven commands with ATA_PROT_NODATA protocol.  In addition to
avoiding the problem mentioned above entirely, this avoids the overhead of
switching to legacy mode and back to ADMA mode for handling cache flushes.
When handling non-DMA-mapped commands, we leave the APRD blank and clear
the NV_CPB_CTL_APRD_VALID field in the CPB so the controller does not
attempt to read it.

Update sata_nv to wait for the controller to indicate via the status
register that it has entered the requested state when switching between
ADMA mode and register mode.  This issue came up recently when debugging
some problems with cache flush command timeouts and while it didn't appear
to fix that problem, this is something we should likely be doing in any
case.

Subject: [PATCH 1354/1971] sata_nv: propagate ata_pci_device_do_resume return
 value

ata_pci_device_do_resume can fail if the PCI device couldn't be re-enabled.
 Update sata_nv to propagate the return value from this call and to not try
to do any other resume activities if it fails.  Fixes a compile warning.

Subject: [PATCH 1355/1971] libata: Early CFA adapters are not required to
 support mode setting

If we are doing a PIO setup for a CFA card and it blows up with a device
error then assume it is an older CFA card which doesn't support this
rather than failing the device out of existance.

Stands seperate to the quieting patch but that is obviously useful with
this change.

Subject: [PATCH 1366/1971] [XFS] Fix a synchronous buftarg flush deadlock when
 freezing.

At the last stage of a freeze, we flush the buftarg synchronously over and
over again until it succeeds twice without skipping any buffers.

The delwri list flush skips pinned buffers, but tries to flush all others.
It removes the buffers from the delwri list, then tries to lock them one
at a time as it traverses the list to issue the I/O. It holds them locked
until we issue all of the I/O and then unlocks them once we've waited for
it to complete.

The problem is that during a freeze, the filesystem may still be doing
stuff - like flushing delalloc data buffers - in the background and hence
we can be trying to lock buffers that were on the delwri list at the same
time. Hence we can get ABBA deadlocks between threads doing allocation and
the buftarg flush (freeze) thread.

Fix it by skipping locked (and pinned) buffers as we traverse the delwri
buffer list.

Subject: [PATCH 1367/1971] [XFS] Prevent buffer overrun in cmn_err().

The message buffer used by cmn_err() is only 256 bytes and some CXFS
messages were exceeding this length. Since we were using vsprintf() and
not checking for buffer overruns we were clobbering memory beyond the
buffer. The size of the buffer has been increased to 1024 bytes so we can
capture these larger messages and we are now using vsnprintf() to prevent
overrunning the buffer size.

Subject: [PATCH 1368/1971] [XFS] Current usage of buftarg flags is incorrect.

The {test,set,clear}_bit() operations take a bit index for the bit to
operate on. The XBT_* flags are defined as bit fields which is incorrect,
not to mention the way the bit fields are enumerated is broken too. This
was only working by chance.

Fix the definitions of the flags and make the code using them use the
{test,set,clear}_bit() operations correctly.

Subject: [PATCH 1369/1971] [XFS] Keep stack usage down for 4k stacks by using
 noinline.

gcc-4.1 and more recent aggressively inline static functions which
increases XFS stack usage by ~15% in critical paths. Prevent this from
occurring by adding noinline to the STATIC definition.

Also uninline some functions that are too large to be inlined and were
causing problems with CONFIG_FORCED_INLINING=y.

Finally, clean up all the different users of inline, __inline and
__inline__ and put them under one STATIC_INLINE macro. For debug kernels
the STATIC_INLINE macro uninlines those functions.

Subject: [PATCH 1371/1971] [XFS] Reduction global superblock lock contention
 near ENOSPC.

The existing per-cpu superblock counter code uses the global superblock
spin lock when we approach ENOSPC for global synchronisation. On larger
machines than this code was originally tested on this can still get
catastrophic spinlock contention due increasing rebalance frequency near
ENOSPC.

By introducing a sleeping lock that is used to serialise balances and
modifications near ENOSPC we prevent contention from needlessly from
wasting the CPU time of potentially hundreds of CPUs.

To reduce the number of balances occuring, we separate the need rebalance
case from the slow allocate case. Now, a counter running dry will trigger
a rebalance during which counters are disabled. Any thread that sees a
disabled counter enters a different path where it waits on the new mutex.
When it gets the new mutex, it checks if the counter is disabled. If the
counter is disabled, then we _know_ that we have to use the global counter
and lock and it is safe to do so immediately. Otherwise, we drop the mutex
and go back to trying the per-cpu counters which we know were re-enabled.

Subject: [PATCH 1376/1971] [XFS] mraccessf & mrupdatef are supposed to be the
 "flags" versions of the functions, but they

a) ignore the flags parameter completely, and b) are never called
directly, only via the flag-less defines anyway

So, drop the #define indirection, and rename mraccessf to mraccess, etc.

Subject: [PATCH 1381/1971] [XFS] Make growfs work for amounts greater than 2TB

The free block modification code has a 32bit interface, limiting the size
the filesystem can be grown even on 64 bit machines. On 32 bit machines,
there are other 32bit variables in transaction structures and interfaces
that need to be expanded to allow this to work.

Subject: [PATCH 1382/1971] [XFS] Fix block reservation mechanism.

The block reservation mechanism has been broken since the per-cpu
superblock counters were introduced. Make the block reservation code work
with the per-cpu counters by syncing the counters, snapshotting the amount
of available space and then doing a modifcation of the counter state
according to the result. Continue in a loop until we either have no space
available or we reserve some space.

Subject: [PATCH 1384/1971] [XFS] Re-initialize the per-cpu superblock counters
 after recovery.

After filesystem recovery the superblock is re-read to bring in any
changes. If the per-cpu superblock counters are not re-initialized from
the superblock then the next time the per-cpu counters are disabled they
might overwrite the global counter with a bogus value.

Subject: [PATCH 1385/1971] [XFS] Fix sub-block zeroing for buffered writes
 into unwritten extents.

When writing less than a filesystem block of data into an unwritten extent
via buffered I/O, __xfs_get_blocks fails to set the buffer new flag. As a
result, the generic code will not zero either edge of the block resulting
in garbage being written to disk either side of the real data. Set the
buffer new state on bufferd writes to unwritten extents to ensure that
zeroing occurs.

Subject: [PATCH 1386/1971] [XFS] Ensure a frozen filesystem has a clean log
 before writing the dummy record.

The current Linux XFS freeze code is a mess. We flush the metadata buffers
out while we are still allowing new transactions to start and then fail to
flush the dirty buffers back out before writing the unmount and dummy
records to the log.

This leads to problems when the frozen filesystem is used for snapshots -
we do log recovery on a readonly image and often it appears that the log
image in the snapshot is not correct. Hence we end up with hangs, oops and
mount failures when trying to mount a snapshot image that has been created
when the filesystem has not been correctly frozen.

To fix this, we need to move th metadata flush to after we wait for all
current transactions to complete in teh second stage of the freeze. This
means that when we write the final log records, the log should be clean
and recovery should never occur on a snapshot image created from a frozen
filesystem.

Subject: [PATCH 1387/1971] [XFS] Fix callers of xfs_iozero() to zero the
 correct range.

The problem is the two callers of xfs_iozero() are rounding out the range
to be zeroed to the end of a fsb and in some cases this extends past the
new eof. The call to commit_write() in xfs_iozero() will cause the Linux
inode's file size to be set too high.

From 7bc5306d74922d9b14f507e1164d8dd852a98ad3 Mon Sep 17 00:00:00 2001
From: Eric Sandeen <sandeen@sandeen.net>
Date: Sat, 10 Feb 2007 18:37:28 +1100
Subject: [PATCH 1394/1971] [XFS] Remove unused header files for MAC and CAP
 checking functionality.

xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used
anywhere in XFS at all. They are left-overs from "to be implement at some
point in the future" functionality that Irix XFS has. If this
functionality ever goes into Linux, it will be provided at a different
layer, most likely through the security hooks in the kernel so we will
never need this functionality in XFS.

Patch provided by Eric Sandeen (sandeen@sandeen.net).

From 2c36ddeda7f04c085d9a612cf8dab5f0a1cd5224 Mon Sep 17 00:00:00 2001
From: Eric Sandeen <sandeen@sandeen.net>
Date: Sat, 10 Feb 2007 18:37:33 +1100
Subject: [PATCH 1395/1971] [XFS] Remove unused arguments from the
 XFS_BTREE_*_ADDR macros.

It makes it incrementally clearer to read the code when the top of a macro
spaghetti-pile only receives the 3 arguments it uses, rather than 2 extra
ones which are not used. Also when you start pulling this thread out of
the sweater (i.e. remove unused args from XFS_BTREE_*_ADDR), a couple
other third arms etc fall off too. If they're not used in the macro, then
they sometimes don't need to be passed to the function calling the macro
either, etc....

Patch provided by Eric Sandeen (sandeen@sandeen.net).

Subject: [PATCH 1397/1971] [XFS] Don't use kmap in xfs_iozero.

kmap() is inefficient and does not scale well. kmap_atomic() is a better
choice. Use the generic wrapper function instead of open coding the
kmap-memset-dcache flush-kunmap stuff.

Subject: [PATCH 1398/1971] [SCSI] aic79xx: use dma_get_required_mask()

As originally noted by Frederic Temporelli, the aic79xx supports 64
bit addressing, but the initialization code of the driver is wrong: it
tests the available memory size instead of testing the maximum
available memory address.

This patch uses the correct dma_get_required_mask() macros to
determine the correct addressing method.

Subject: [PATCH 1409/1971] [MIPS] signal: do not inline functions in
 signal-common.h

These functions are quite big and there are no points to make
them inlined. So this patch moves the functions implementation
in signal.c and make them available for others source files
which need them.

Subject: [PATCH 1410/1971] [MIPS] signal: clean up sigframe structure

This patch makes 'struct sigframe' declaration avalaible for all signals
code. It allows signal32 to not have its own declaration.

This patch also removes all ICACHE_REFILLS_WORKAROUND_WAR tests in
structure declaration and hopefully make them more readable.

Subject: [PATCH 1411/1971] [MIPS] signal32: remove duplicate code

There's no point for signal32.c to redefine get_sigframe().
It should use the one define in signal.c instead.

The same stands for install_sigtramp().

Subject: [PATCH 1415/1971] [MIPS] signal32: no need to save c0_status register
 in setup_sigcontext32()

All the information in the MIPS c0_status register is priviledged.
Nothing that would constitute part of the thread context.

The one flag one could possibly argument about might be c0_status.fr
but none of the ABIs or tools or application software can make use
of it.

So for consistency with restore_sigcontext32(), which does not
restore c0_status register, this patch remove the saving part.

Subject: [PATCH 1416/1971] [MIPS] signal: do not use save_static_function()
 anymore

This macro was used to save static registers before calling
sys_sigsuspend() and sys_sigreturn().

For the sys_sigreturn() case, there's no point to save them
since they have been already saved by setup_sigcontext()
before calling the signal handler.

For the sys_sigsuspend() case, I don't see any reasons...

Subject: [PATCH 1453/1971] [UDP]: UDP can use sk_hash to speedup lookups

In a prior patch, I introduced a sk_hash field (__sk_common.skc_hash)  to let
tcp lookups use one cache line per unmatched entry instead of two.

We can also use sk_hash to speedup UDP part as well. We store in sk_hash the
hnum value, and use sk->sk_hash (same cache line than 'next' pointer),
instead of inet->num (different cache line)

Note : We still have a false sharing problem for SMP machines, because
sock_hold(sock) dirties the cache line containing the 'next' pointer. Not
counting the udp_hash_lock rwlock. (did someone mentioned RCU ? :) )

 'next' pointer

This patch introduces an anonymous union to nicely express the fact that all
objects inherited from struct dst_entry should access to the generic 'next'
pointer but with appropriate type verification.

This patch is a prereq before following patches.

Subject: [PATCH 1457/1971] [IPV4]: Convert ipv4 route to use the new dst_entry
 'next' pointer

This patch removes the rt_next pointer from 'struct rtable.u' union,
and renames u.rt_next to u.dst_rt_next.

It also moves 'struct flowi' right after 'struct dst_entry' to prepare
the gain on lookups.

Subject: [PATCH 1458/1971] [IPV6]: Convert ipv6 route to use the new dst_entry
 'next' pointer

This patch removes the next pointer from 'struct rt6_info.u' union,
and renames u.next to u.dst.rt6_next.

Subject: [PATCH 1459/1971] [DECNET]: Convert decnet route to use the new
 dst_entry 'next' pointer

This patch removes the next pointer from 'struct dn_route.u' union,
and renames u.rt_next to u.dst.dn_next.

It also moves 'struct flowi' right after 'struct dst_entry' to prepare
speedup lookups.

Subject: [PATCH 1460/1971] [NET]: Reorder fields of struct dst_entry

This last patch (but not least :) ) finally moves the next pointer at
the end of struct dst_entry. This permits to perform route cache
lookups with a minimal cost of one cache line per entry, instead of
two.

Both 32bits and 64bits platforms benefit from this new layout.

Subject: [PATCH 1461/1971] [XFRM] IPV6: Fix outbound RO transformation which
 is broken by IPsec tunnel patch.

It seems to miss RO mode path by IPv6 over IPv4 IPsec tunnel patch
when it changed semantics to check the mode from
"xfrm[i]->props.mode != XFRM_MODE_TRANSPORT" to
"xfrm[i]->props.mode == XFRM_MODE_TUNNEL" before changing address.
It also makes two incline functions __xfrm6_bundle_addr_{remote,local}
are used by nobody.

This patch fixes it.

Subject: [PATCH 1462/1971] [IPV4]: Restore multipath routing after rt_next
 changes.

I forgot to test build this part of the networking code... Sorry guys.
This patch renames u.rt_next to u.dst.rt_next

From d18d7682c18b617f523df6beea5ea0bd396ed0bd Mon Sep 17 00:00:00 2001

Subject: [PATCH 1463/1971] [PARTITION]: Add whole_disk attribute.

Some partitioning systems create special partitions that
span the entire disk.  One example are Sun partitions, and
this whole-disk partition exists to tell the firmware the
extent of the entire device so it can load the boot block
and do other things.

Such partitions should not be treated as normal partitions,
because all the other partitions overlap this whole-disk one.
So we'd see multiple instances of the same UUID etc. which
we do not want.  udev and friends can thus search for this
'whole_disk' attribute and use it to decide to ignore the
partition.

Subject: [PATCH 1465/1971] [SPARC64] IRQ: Use irq_desc->chip_data instead of

Otherwise we can't use the generic MSI code.

Furthermore, properly use the {get,set}_irq_foo() abstracted
interfaces instead of direct accesses to irq_desc[]->foo.

Subject: [PATCH 1466/1971] [SPARC64]: Add PCI MSI support on Niagara.

This is kind of hokey, we could use the hardware provided facilities
much better.

MSIs are assosciated with MSI Queues.  MSI Queues generate interrupts
when any MSI assosciated with it is signalled.  This suggests a
two-tiered IRQ dispatch scheme:

	MSI Queue interrupt --> queue interrupt handler
		MSI dispatch --> driver interrupt handler

But we just get one-level under Linux currently.  What I'd like to do
is possibly stick the IRQ actions into a per-MSI-Queue data structure,
and dispatch them form there, but the generic IRQ layer doesn't
provide a way to do that right now.

So, the current kludge is to "ACK" the interrupt by processing the
MSI Queue data structures and ACK'ing them, then we run the actual
handler like normal.

We are wasting a lot of useful information, for example the MSI data
and address are provided with ever MSI, as well as a system tick if
available.  If we could pass this into the IRQ handler it could help
with certain things, in particular for PCI-Express error messages.

The MSI entries on sparc64 also tell you exactly which bus/device/fn
sent the MSI, which would be great for error handling when no
registered IRQ handler can service the interrupt.

We override the disable/enable IRQ chip methods in sun4v_msi, so we
have to call {mask,unmask}_msi_irq() directly from there.  This is
another ugly wart.

Subject: [PATCH 1469/1971] tifm_sd: treat "status error" as normal command
 completion

TI FlasMedia controller attempts to validate command responses and
issues a "status error" if response does not matches its perceived
(by controller) value. As mmc layer does its own validation we can
safely ignore the controller's opinion.

Subject: [PATCH 1470/1971] [PATCH] slab: remove broken PageSlab check from
 kfree_debugcheck

The PageSlab debug check in kfree_debugcheck() is broken for compound
pages.  It is also redundant as we already do BUG_ON for non-slab pages in
page_get_cache() and page_get_slab() which are always called before we free
any actual objects.

Subject: [PATCH 1471/1971] [PATCH] slab: cache alloc cleanups

Clean up __cache_alloc and __cache_alloc_node functions a bit.  We no
longer need to do NUMA_BUILD tricks and the UMA allocation path is much
simpler.  No functional changes in this patch.

Note: saves few kernel text bytes on x86 NUMA build due to using gotos in
__cache_alloc_node() and moving __GFP_THISNODE check in to
fallback_alloc().

Subject: [PATCH 1474/1971] [PATCH] Avoid excessive sorting of early_node_map[]

find_min_pfn_for_node() and find_min_pfn_with_active_regions() sort
early_node_map[] on every call.  This is an excessive amount of sorting and
that can be avoided.  This patch always searches the whole early_node_map[]
in find_min_pfn_for_node() instead of returning the first value found.  The
map is then only sorted once when required.  Successfully boot tested on a
number of machines.

After do_wp_page has tested page_mkwrite, it must release old_page after
acquiring page table lock, not before: at some stage that ordering got
reversed, leaving a (very unlikely) window in which old_page might be
truncated, freed, and reused in the same position.

Subject: [PATCH 1478/1971] [PATCH] Use ZVC for inactive and active counts

The determination of the dirty ratio to determine writeback behavior is
currently based on the number of total pages on the system.

However, not all pages in the system may be dirtied.  Thus the ratio is always
too low and can never reach 100%.  The ratio may be particularly skewed if
large hugepage allocations, slab allocations or device driver buffers make
large sections of memory not available anymore.  In that case we may get into
a situation in which f.e.  the background writeback ratio of 40% cannot be
reached anymore which leads to undesired writeback behavior.

This patchset fixes that issue by determining the ratio based on the actual
pages that may potentially be dirty.  These are the pages on the active and
the inactive list plus free pages.

The problem with those counts has so far been that it is expensive to
calculate these because counts from multiple nodes and multiple zones will
have to be summed up.  This patchset makes these counters ZVC counters.  This
means that a current sum per zone, per node and for the whole system is always
available via global variables and not expensive anymore to calculate.

The patchset results in some other good side effects:

- Removal of the various functions that sum up free, active and inactive
  page counts

- Cleanup of the functions that display information via the proc filesystem.

This patch:

The use of a ZVC for nr_inactive and nr_active allows a simplification of some
counter operations.  More ZVC functionality is used for sums etc in the
following patches.

Subject: [PATCH 1480/1971] [PATCH] Reorder ZVCs according to cacheline

The global and per zone counter sums are in arrays of longs.  Reorder the ZVCs
so that the most frequently used ZVCs are put into the same cacheline.  That
way calculations of the global, node and per zone vm state touches only a
single cacheline.  This is mostly important for 64 bit systems were one 128
byte cacheline takes only 8 longs.

Subject: [PATCH 1481/1971] [PATCH] Drop free_pages()

nr_free_pages is now a simple access to a global variable.  Make it a macro
instead of a function.

The nr_free_pages now requires vmstat.h to be included.  There is one
occurrence in power management where we need to add the include.  Directly
refrer to global_page_state() there to clarify why the #include was added.

Subject: [PATCH 1485/1971] [PATCH] optional ZONE_DMA: deal with cases of
 ZONE_DMA meaning the first zone

This patchset follows up on the earlier work in Andrew's tree to reduce the
number of zones.  The patches allow to go to a minimum of 2 zones.  This one
allows also to make ZONE_DMA optional and therefore the number of zones can be
reduced to one.

ZONE_DMA is usually used for ISA DMA devices.  There are a number of reasons
why we would not want to have ZONE_DMA

1. Some arches do not need ZONE_DMA at all.

2. With the advent of IOMMUs DMA zones are no longer needed.
   The necessity of DMA zones may drastically be reduced
   in the future. This patchset allows a compilation of
   a kernel without that overhead.

3. Devices that require ISA DMA get rare these days. All
   my systems do not have any need for ISA DMA.

4. The presence of an additional zone unecessarily complicates
   VM operations because it must be scanned and balancing
   logic must operate on its.

5. With only ZONE_NORMAL one can reach the situation where
   we have only one zone. This will allow the unrolling of many
   loops in the VM and allows the optimization of varous
   code paths in the VM.

6. Having only a single zone in a NUMA system results in a
   1-1 correspondence between nodes and zones. Various additional
   optimizations to critical VM paths become possible.

Many systems today can operate just fine with a single zone.  If you look at
what is in ZONE_DMA then one usually sees that nothing uses it.  The DMA slabs
are empty (Some arches use ZONE_DMA instead of ZONE_NORMAL, then ZONE_NORMAL
will be empty instead).

On all of my systems (i386, x86_64, ia64) ZONE_DMA is completely empty.  Why
constantly look at an empty zone in /proc/zoneinfo and empty slab in
/proc/slabinfo?  Non i386 also frequently have no need for ZONE_DMA and zones
stay empty.

The patchset was tested on i386 (UP / SMP), x86_64 (UP, NUMA) and ia64 (NUMA).

The RFC posted earlier (see
http://marc.theaimsgroup.com/?l=linux-kernel&m=115231723513008&w=2) had lots
of #ifdefs in them.  An effort has been made to minize the number of #ifdefs
and make this as compact as possible.  The job was made much easier by the
ongoing efforts of others to extract common arch specific functionality.

I have been running this for awhile now on my desktop and finally Linux is
using all my available RAM instead of leaving the 16MB in ZONE_DMA untouched:

  all_unreclaimable: 0
  prev_priority:     12
  temp_priority:     12
  start_pfn:         0

This patch:

In two places in the VM we use ZONE_DMA to refer to the first zone.  If
ZONE_DMA is optional then other zones may be first.  So simply replace
ZONE_DMA with zone 0.

This also fixes ZONETABLE_PGSHIFT.  If we have only a single zone then
ZONES_PGSHIFT may become 0 because there is no need anymore to encode the zone
number related to a pgdat.  However, we still need a zonetable to index all
the zones for each node if this is a NUMA system.  Therefore define
ZONETABLE_SHIFT unconditionally as the offset of the ZONE field in page flags.

Subject: [PATCH 1486/1971] [PATCH] optional ZONE_DMA: introduce
 CONFIG_ZONE_DMA

This patch simply defines CONFIG_ZONE_DMA for all arches.  We later do special
things with CONFIG_ZONE_DMA after the VM and an arch are prepared to work
without ZONE_DMA.

CONFIG_ZONE_DMA can be defined in two ways depending on how an architecture
handles ISA DMA.

First if CONFIG_GENERIC_ISA_DMA is set by the arch then we know that the arch
needs ZONE_DMA because ISA DMA devices are supported.  We can catch this in
mm/Kconfig and do not need to modify arch code.

Second, arches may use ZONE_DMA in an unknown way.  We set CONFIG_ZONE_DMA for
all arches that do not set CONFIG_GENERIC_ISA_DMA in order to insure backwards
compatibility.  The arches may later undefine ZONE_DMA if their arch code has
been verified to not depend on ZONE_DMA.

Subject: [PATCH 1487/1971] [PATCH] optional ZONE_DMA: optional ZONE_DMA in the
 VM

Make ZONE_DMA optional in core code.

- ifdef all code for ZONE_DMA and related definitions following the example
  for ZONE_DMA32 and ZONE_HIGHMEM.

- Without ZONE_DMA, ZONE_HIGHMEM and ZONE_DMA32 we get to a ZONES_SHIFT of
  0.

- Modify the VM statistics to work correctly without a DMA zone.

- Modify slab to not create DMA slabs if there is no ZONE_DMA.

Subject: [PATCH 1491/1971] [PATCH] Set CONFIG_ZONE_DMA for arches with
 GENERIC_ISA_DMA

As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA
channel management.  Other functionality may still expect GFP_DMA to
provide memory below 16M.  So we need to make sure that CONFIG_ZONE_DMA is
set independent of CONFIG_GENERIC_ISA_DMA.  Undo the modifications to
mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set
theses explicitly in each arches Kconfig.

Reviews must occur for each arch in order to determine if ZONE_DMA can be
switched off.  It can only be switched off if we know that all devices
supported by a platform are capable of performing DMA transfers to all of
memory (Some arches already support this: uml, avr32, sh sh64, parisc and
IA64/Altix).

In order to switch ZONE_DMA off conditionally, one would have to establish
a scheme by which one can assure that no drivers are enabled that are only
capable of doing I/O to a part of memory, or one needs to provide an
alternate means of performing an allocation from a specific range of memory
(like provided by alloc_pages_range()) and insure that all drivers use that
call.  In that case the arches alloc_dma_coherent() may need to be modified
to call alloc_pages_range() instead of relying on GFP_DMA.

Subject: [PATCH 1492/1971] [PATCH] zoneid: fix up calculations for
 ZONEID_PGSHIFT

Currently if we have a non-zero ZONES_SHIFT we assume we are able to rely
on that as the bottom edge of the ZONEID, if not then we use the
NODES_PGOFF as the right end of either NODES _or_ SECTION.  This latter is
more luck than judgement and would be incorrect if we reordered the
SECTION,NODE,ZONE options in the fields space.

Really what we want is the lower of the right hand end of the two fields we
are using (either NODE,ZONE or SECTION,ZONE).  Codify that explicitly.  As
always allow for there being no bits in either of the fields, such as might
be valid in a non-numa machine with only a zone NORMAL.

I have checked that the compiler is still able to constant fold all of this
away correctly.

Subject: [PATCH 1493/1971] [PATCH] simplify shmem_aops.set_page_dirty() method

shmem backed file does not have page writeback, nor it participates in
backing device's dirty or writeback accounting.  So using generic
__set_page_dirty_nobuffers() for its .set_page_dirty aops method is a bit
overkill.  It unnecessarily prolongs shm unmap latency.

For example, on a densely populated large shm segment (sevearl GBs), the
unmapping operation becomes painfully long.  Because at unmap, kernel
transfers dirty bit in PTE into page struct and to the radix tree tag.  The
operation of tagging the radix tree is particularly expensive because it
has to traverse the tree from the root to the leaf node on every dirty
page.  What's bothering is that radix tree tag is used for page write back.
 However, shmem is memory backed and there is no page write back for such
file system.  And in the end, we spend all that time tagging radix tree and
none of that fancy tagging will be used.  So let's simplify it by introduce
a new aops __set_page_dirty_no_writeback and this will speed up shm unmap.

 __set_page_dirty_no_writeback

As pointed out by Hugh, ramfs would also benefit from using the new
set_page_dirty aop method for memory backed file systems.

Subject: [PATCH 1495/1971] [PATCH] do not disturb page referenced state when
 unmapping memory range

When kernel unmaps an address range, it needs to transfer PTE state into
page struct.  Currently, kernel transfer access bit via
mark_page_accessed().  The call to mark_page_accessed in the unmap path
doesn't look logically correct.

At unmap time, calling mark_page_accessed will causes page LRU state to be
bumped up one step closer to more recently used state.  It is causing quite
a bit headache in a scenario when a process creates a shmem segment, touch
a whole bunch of pages, then unmaps it.  The unmapping takes a long time
because mark_page_accessed() will start moving pages from inactive to
active list.

I'm not too much concerned with moving the page from one list to another in
LRU.  Sooner or later it might be moved because of multiple mappings from
various processes.  But it just doesn't look logical that when user asks a
range to be unmapped, it's his intention that the process is no longer
interested in these pages.  Moving those pages to active list (or bumping
up a state towards more active) seems to be an over reaction.  It also
prolongs unmapping latency which is the core issue I'm trying to solve.

As suggested by Peter, we should still preserve the info on pte young
pages, but not more.

Subject: [PATCH 1496/1971] [PATCH] make reading /proc/sys/kernel/cap-bould not
 require CAP_SYS_MODULE

Reading /proc/sys/kernel/cap-bound requires CAP_SYS_MODULE.  (see
proc_dointvec_bset in kernel/sysctl.c)

sysctl appears to drive all over proc reading everything it can get it's
hands on and is complaining when it is being denied access to read
cap-bound.  Clearly writing to cap-bound should be a sensitive operation
but requiring CAP_SYS_MODULE to read cap-bound seems a bit to strong.  I
believe the information could with reasonable certainty be obtained by
looking at a bunch of the output of /proc/pid/status which has very low
security protection, so at best we are just getting a little obfuscation of
information.

Currently SELinux policy has to 'dontaudit' capability checks for
CAP_SYS_MODULE for things like sysctl which just want to read cap-bound.
In doing so we also as a byproduct have to hide warnings of potential
exploits such as if at some time that sysctl actually tried to load a
module.  I wondered if anyone would have a problem opening cap-bound up to
read from anyone?

Subject: [PATCH 1499/1971] [PATCH] PM: Change code ordering in main.c

As indicated in a recent thread on Linux-PM, it's necessary to call
pm_ops->finish() before devce_resume(), but enable_nonboot_cpus() has to be
called before pm_ops->finish() (cf.
http://lists.osdl.org/pipermail/linux-pm/2006-November/004164.html).  For
consistency, it seems reasonable to call disable_nonboot_cpus() after
device_suspend().

This way the suspend code will remain symmetrical with respect to the resume
code and it may allow us to speed up things in the future by suspending and
resuming devices and/or saving the suspend image in many threads.

The following series of patches reorders the suspend and resume code so that
nonboot CPUs are disabled after devices have been suspended and enabled before
the devices are resumed.  It also causes pm_ops->finish() to be called after
enable_nonboot_cpus() wherever necessary.

This patch:

Change the ordering of code in kernel/power/main.c so that device_suspend()
is called before disable_nonboot_cpus() and pm_ops->finish() is called after
enable_nonboot_cpus() and before device_resume(), as indicated by recent
discussion on Linux-PM
(cf. http://lists.osdl.org/pipermail/linux-pm/2006-November/004164.html).

Date: Sat, 10 Feb 2007 01:43:35 -0800
Subject: [PATCH 1503/1971] [PATCH] swsusp: Change pm_ops handling by userland
 interface

Make the userland interface of swsusp call pm_ops->finish() after
enable_nonboot_cpus() and before resume_device(), as indicated by the recent
discussion on Linux-PM (cf.
http://lists.osdl.org/pipermail/linux-pm/2006-November/004164.html).

This patch changes the SNAPSHOT_PMOPS ioctl so that its first function,
PMOPS_PREPARE, only sets a switch turning the platform suspend mode on, and
its last function, PMOPS_FINISH, only checks if the platform mode is enabled.
This should allow the older userland tools to work with new kernels without
any modifications.

The changes here only affect the userland interface of swsusp.

 update_mmu_cache

Fix do_page_fault and update_mmu_cache.

  * Fix do_page_fault (vmalloc_fault:) to pass error_code correctly
    to update_mmu_cache by using a thread-fault code for all m32r chips.

  * Fix update_mmu_cache for OPSP chip
    - #ifdef CONFIG_CHIP_OPSP portion is a workaround of OPSP;
      Add a notfound-case operation to update_mmu_cache for OPSP
      like other m32r chip.
    - Fix pte_data that was not initialized if no entry found.

Subject: [PATCH 1507/1971] [PATCH] m32r: fix kernel entry address of vmlinux

This patch fixes the kernel entry point address of vmlinux.

The m32r kernel entry address is 0x08002000 (physical).
But, so far, the ENTRY point written in vmlinux.lds.S was not point
the correct kernel entry address.

(before fix)
    $ objdump -x vmlinux
    vmlinux:     file format elf32-m32r-linux
    vmlinux
    architecture: m32r2, flags 0x00000112:
    EXEC_P, HAS_SYMS, D_PAGED
    start address 0x88002090	/* NG */
        :
    Sections:
    Idx Name          Size      VMA       LMA       File off  Algn
      0 .empty_zero_page 00001000  88001000  88001000  00001000  2**12
                      CONTENTS, ALLOC, LOAD, DATA
      1 .boot         0000008c  88002000  88002000  00002000  2**2
                      CONTENTS, ALLOC, LOAD, READONLY, CODE
      2 .text         001ab694  88002090  88002090  00002090  2**4
                      CONTENTS, ALLOC, LOAD, READONLY, CODE
        :

(after fix)
    $ objdump -x vmlinux
    vmlinux:     file format elf32-m32r-linux
    vmlinux
    architecture: m32r2, flags 0x00000112:
    EXEC_P, HAS_SYMS, D_PAGED
    start address 0x08002000	/* OK */
        :

This fix also remedies the following GDB error message (of gdb-6.4 or after)
at the first operation of kernel debugging:
"Previous frame identical to this frame (corrupt stack?)".

Subject: [PATCH 1509/1971] [PATCH] m68k: work around binutils tokenizer change

Recent as(1) doesn't think that .  terminates a macro name, so getuser.l is
_not_ treated as invoking getuser with .l as the first argument.
arch/m68k/math-emu relies on old behaviour, so it gets a lot of undefined
macros with more or less current binutils.

Note that this behaviour remains in all recent versions and is unrelated to
another binutils problems we used to have for a while (having (%a0)+ parsed
as two arguments).  This one is there to stay; it's an intentional and
documented change.

.irp <identifier> <words>
[text]
.endr
expands to a copy of text per each word, with \<identifier> replaced with
corresponding word.  Again, what happens depends on whether gas_ident.x
is treated as one or as two tokens; in the former case we'll get old_gas
incremented once, in the latter - twice.  The rest is obvious.

Unlike .macro argument list _anything_ is explicitly allowed after
.irp <identifier>; here we are on very safe ground.  And yes, it does
work with all gas variants I've got here (including vanilla 2.15, 2.16,
2.16.1 and 2.17, plus debian and FC binutils).

Subject: [PATCH 1510/1971] [PATCH] kernel/time/clocksource.c needs struct
 task_struct on m68k

kernel/time/clocksource.c needs struct task_struct on m68k.

Because it uses spin_unlock_irq(), which, on m68k, uses hardirq_count(), which
uses preempt_count(), which needs to dereference struct task_struct, we
have to include sched.h. Because it would cause a loop inclusion, we
cannot include sched.h in any other of asm-m68k/system.h,
linux/thread_info.h, linux/hardirq.h, which leaves this ugly include in
a C file as the only simple solution.

Subject: [PATCH 1518/1971] [PATCH] uml: console locking fixes

Clean up the console driver locking.  There are various problems here,
including sleeping under a spinlock and spinlock recursion, some of which are
fixed here.  This patch deals with the locking involved with opens and closes.
 The problem is that an mconsole request to change a console's configuration
can race with an open.  Changing a configuration should only be done when a
console isn't opened.  Also, an open must be looking at a stable
configuration.  In addition, a get configuration request must observe the same
locking since it must also see a stable configuration.  With the old locking,
it was possible for this to hang indefinitely in some cases because open would
block for a long time waiting for a connection from the host while holding the
lock needed by the mconsole request.

As explained in the long comment, this is fixed by adding a spinlock for the
use count and configuration and a mutex for the actual open and close.

+/* Normally, a driver like this can rely mostly on the tty layer
+ * locking, particularly when it comes to the driver structure.
+ * However, in this case, mconsole requests can come in "from the
+ * side", and race with opens and closes.
+ *
+ * The problem comes from line_setup not wanting to sleep if
+ * the device is open or being opened.  This can happen because the
+ * first opener of a device is responsible for setting it up on the
+ * host, and that can sleep.  The open of a port device will sleep
+ * until someone telnets to it.
+ *
+ * The obvious solution of putting everything under a mutex fails
+ * because then trying (and failing) to change the configuration of an
+ * open(ing) device will block until the open finishes.  The right
+ * thing to happen is for it to fail immediately.
+ *
+ * We can put the opening (and closing) of the host device under a
+ * separate lock, but that has to be taken before the count lock is
+ * released.  Otherwise, you open a window in which another open can
+ * come through and assume that the host side is opened and working.
+ *
+ * So, if the tty count is one, open will take the open mutex
+ * inside the count lock.  Otherwise, it just returns. This will sleep
+ * if the last close is pending, and will block a setup or get_config,
+ * but that should not last long.
+ *
+ * So, what we end up with is that open and close take the count lock.
+ * If the first open or last close are happening, then the open mutex
+ * is taken inside the count lock and the host opening or closing is done.
+ *
+ * setup and get_config only take the count lock.  setup modifies the
+ * device configuration only if the open count is zero.  Arbitrarily
+ * long blocking of setup doesn't happen because something would have to be
+ * waiting for an open to happen.  However, a second open with
+ * tty->count == 1 can't happen, and a close can't happen until the open
+ * had finished.
+ *
+ * We can't maintain our own count here because the tty layer doesn't
+ * match opens and closes.  It will call close if an open failed, and
+ * a tty hangup will result in excess closes.  So, we rely on
+ * tty->count instead.  It is one on both the first open and last close.

Subject: [PATCH 1519/1971] [PATCH] uml: return hotplug errors to host

I noticed that errors happening while hotplugging devices from the host were
never returned back to the mconsole client.  In some cases, success was
returned instead of even an information-free error.

This patch cleans that up by having the low-level configuration code pass back
an error string along with an error code.  At the top level, which knows
whether it is early boot time or responding to an mconsole request, the string
is printk'd or returned to the mconsole client.

There are also whitespace and trivial code cleanups in the surrounding code.

Subject: [PATCH 1522/1971] [PATCH] uml: add locking to network transport
 registration

The registration of host network transports needed some locking.  The
transport list itself is locked, but calls to the registration routines are
not.  This is compensated for by checking that a transport structure is not
yet on any list.

I also took the opportunity to const all fields in the transport structure
except the list, which obviously can be modified.

Subject: [PATCH 1524/1971] [PATCH] uml: watchdog driver locking

Replace BKL use with a spinlock.

Also fix the control so that open doesn't return holding a lock.

Subject: [PATCH 1528/1971] [PATCH] uml: mconsole locking

Locking fixes.  Locking was totally lacking for the mconsole_devices, which
got a spin lock, and the unplugged pages data, which got a mutex.

The locking of the mconsole console output code was confused.  Now, the
console_lock (renamed to client_lock) protects the clients list.

The chan_opts structure is mostly const, and needs no locking.  Comment the
lack of locking on the one field that can change.

Make all the other fields const.  It turned out that console_open_chan didn't
use its chan_opts argument, so that is deleted from the function and its
callers.

Subject: [PATCH 1537/1971] [PATCH] uml: console locking commentary and code
 cleanup

Remove the last vestiges of devfs from console registration.  Change the name
of the function, plus remove a couple of unused fields from the line_driver
structure.

struct lines is no longer needed, all traces of it are gone.

The only way that I can see to mark a structure as being almost-const is to
individually const the fields.  This is the case for the line_driver
structure, which has only one modifiable field - a list_head in a
sub-structure.

Subject: [PATCH 1538/1971] [PATCH] uml: fix previous console locking

Eliminate the open_mutex after complaints from Blaisorblade.  It turns out
that the tty count provides the information needed to tell whether we are the
first opener or last closer.

  * However, in this case, mconsole requests can come in "from the
  * side", and race with opens and closes.
  *
- * The problem comes from line_setup not wanting to sleep if
- * the device is open or being opened.  This can happen because the
- * first opener of a device is responsible for setting it up on the
- * host, and that can sleep.  The open of a port device will sleep
- * until someone telnets to it.
+ * mconsole config requests will want to be sure the device isn't in
+ * use, and get_config, open, and close will want a stable
+ * configuration.  The checking and modification of the configuration
+ * is done under a spinlock.  Checking whether the device is in use is
+ * line->tty->count > 1, also under the spinlock.
  *
- * The obvious solution of putting everything under a mutex fails
- * because then trying (and failing) to change the configuration of an
- * open(ing) device will block until the open finishes.  The right
- * thing to happen is for it to fail immediately.
- *
- * We can put the opening (and closing) of the host device under a
- * separate lock, but that has to be taken before the count lock is
- * released.  Otherwise, you open a window in which another open can
- * come through and assume that the host side is opened and working.
- *
- * So, if the tty count is one, open will take the open mutex
- * inside the count lock.  Otherwise, it just returns. This will sleep
- * if the last close is pending, and will block a setup or get_config,
- * but that should not last long.
- *
- * So, what we end up with is that open and close take the count lock.
- * If the first open or last close are happening, then the open mutex
- * is taken inside the count lock and the host opening or closing is done.
- *
- * setup and get_config only take the count lock.  setup modifies the
- * device configuration only if the open count is zero.  Arbitrarily
- * long blocking of setup doesn't happen because something would have to be
- * waiting for an open to happen.  However, a second open with
- * tty->count == 1 can't happen, and a close can't happen until the open
- * had finished.
- *
- * We can't maintain our own count here because the tty layer doesn't
- * match opens and closes.  It will call close if an open failed, and
- * a tty hangup will result in excess closes.  So, we rely on
- * tty->count instead.  It is one on both the first open and last close.
+ * tty->count serves to decide whether the device should be enabled or
+ * disabled on the host.  If it's equal to 1, then we are doing the
+ * first open or last close.  Otherwise, open and close just return.

Subject: [PATCH 1548/1971] [PATCH] uml: add per-device queues and locks to ubd
 driver

Replace global queue and lock with per-device queues and locks.  Mostly a
straightforward replacement of ubd_io_lock with dev->lock and ubd_queue with
dev->queue.

Complications -
	There was no way to get a request struct (and queue) from the
structure sent to the io_thread, so a pointer to the request was
added.  This is needed in ubd_handler in order to kick do_ubd_request
to process another request.
	Queue initialization is moved from ubd_init to ubd_add.

Subject: [PATCH 1553/1971] [PATCH] uml: libc-dependent code should call libc
 directly

We shouldn't be using the os wrappers from os code - we can use libc directly.
This patch replaces wrapper calls with libc calls.

It turns out that os_sigio_async had only one caller, which was in startup.c,
so that function is moved there and its name changed.

Subject: [PATCH 1559/1971] [PATCH] uml: umid tidying

Add an error message when two umids are put on the command line.

umid.h is kind of pointless since it only declares one thing, and that
is already declared in os.h.

Commented the lack of locking of some data in os-Linux/umid.h.

Subject: [PATCH 1563/1971] [PATCH] uml: fix error output during early boot

The startup code panics a lot if anything goes wrong early on.  This is wrong
for several reasons, like the kernel isn't running, so you can't really be
calling into it yet, but the harm comes from useful error messages being
trapped in the printk ring where no one will ever see them.

This patch changes these panics to perror and printf in wrappers which also
exit.  Normal, informational, prints are also wrapped so that fflush(stdout)
is called after each one.  This is so the output appears in the correct
sequence in the event of an error.

Subject: [PATCH 1564/1971] [PATCH] uml: x86_64 thread fixes

x86_64 needs some TLS fixes.  What was missing was remembering the child
thread id during clone and stuffing it into the child during each context
switch.

The %fs value is stored separately in the thread structure since the host
controls what effect it has on the actual register file.  The host also needs
to store it in its own thread struct, so we need the value kept outside the
register file.

arch_prctl_skas was fixed to call PTRACE_ARCH_PRCTL appropriately.  There is
some saving and restoring of registers in the ARCH_SET_* cases so that the
correct set of registers are changed on the host and restored to the process
when it runs again.

Subject: [PATCH 1565/1971] [PATCH] uml: x86_64 ptrace fixes

This patch fixes some missing ptrace bits on x86_64.  PTRACE_ARCH_PRCTL is
hooked up and implemented.  This required generalizing arch_prctl_skas
slightly to take a task_struct to modify.  Previously, it always operated on
current.

Reading and writing the debug registers is also enabled by un-ifdefing the
code that implements that.  It turns out that x86_64 is identical to i386, so
the same code can be used.

+4. USERSPACE PROGRAMMING
+------------------------
+
+The cfag12864bfb describes a framebuffer device (/dev/fbX).
+
+It has a size of 1024 bytes = 1 Kbyte.
+Each bit represents one pixel. If the bit is high, the pixel will
+turn on. If the pixel is low, the pixel will turn off.
+
+You can use the framebuffer as a file: fopen, fwrite, fclose...
+Although the LCD won't get updated until the next refresh time arrives.
+
+Also, you can mmap the framebuffer: open & mmap, munmap & close...
+which is the best option for most uses.
+
+Check Documentation/auxdisplay/cfag12864b-example.c
+for a real working userspace complete program with usage examples.

+	  The third  standard parallel port address is 0x3BC.
+
+	  You can specify a different address if you need.
+
+	  If you don't know what I'm talking about, load the parport module,
+	  and execute "dmesg" or "cat /proc/ioports". You can see there how
+	  many parallel ports are present and which address each one has.
+
+	  Usually you only need to use 0x378.
+
+	  If you compile this as a module, you can still override this
+	  using the module parameters.

+config KS0108_DELAY
+	int "Delay between each control writing (microseconds)"

+	default "2"
+	---help---
+	  Amount of time the ks0108 should wait between each control write
+	  to the parallel port.
+
+	  If your driver seems to miss random writings, increment this.
+
+	  If you don't know what I'm talking about, ignore it.
+

+	tristate "CFAG12864B LCD"
+	depends on X86
+	depends on FB
+	depends on KS0108
+	default n
+	---help---
+	  If you have a Crystalfontz 128x64 2-color LCD, cfag12864b Series,
+	  say Y. You also need the ks0108 LCD Controller driver.
+
+	  For help about how to wire your LCD to the parallel port,
+	  check Documentation/auxdisplay/cfag12864b
+
+	  Depends on the x86 arch and the framebuffer support.
+
+	  The LCD framebuffer driver can be attached to a console.
+	  It will work fine. However, you can't attach it to the fbdev driver
+	  of the xorg server.
+
+	  To compile this as a module, choose M here:
+	  the modules will be called cfag12864b and cfag12864bfb.
+
+	  If unsure, say N.
+
+config CFAG12864B_RATE
+       int "Refresh rate (hertz)"
+	depends on CFAG12864B
+	default "20"
+	---help---
+	  Refresh rate of the LCD.
+
+	  As the LCD is not memory mapped, the driver has to make the work by
+	  software. This means you should be careful setting this value higher.
+	  If your CPUs are really slow or you feel the system is slowed down,
+	  decrease the value.
+
+	  Be careful modifying this value to a very high value:
+	  You can freeze the computer, or the LCD maybe can't draw as fast as you
+	  are requesting.
+
+	  If you don't know what I'm talking about, ignore it.
+
+	  If you compile this as a module, you can still override this
+	  value using the module parameters.

Subject: [PATCH 1568/1971] [PATCH] Add retain_initrd boot option

Add retain_initrd option to control freeing of initrd memory after
extraction.  By default, free memory as previously.

The first boot will need to hold a copy of the in memory fs for the second
boot.  This image can be large (much larger than the kernel), hence we can
save time when the memory loader is slow.  Also, it reduces the memory
footprint while extracting the first boot since you don't need another copy
of the fs.

Subject: [PATCH 1569/1971] [PATCH] vt: refactor console SAK processing

This does several things.
- It moves looking up of the current foreground console into process
  context where we can safely take the semaphore that protects this
  operation.
- It uses the new flavor of work queue processing.
- This generates a factor of do_SAK, __do_SAK that runs immediately.
- This calls __do_SAK with the console semaphore held ensuring nothing
  else happens to the console while we process the SAK operation.
- With the console SAK processing moved into process context this
  patch removes the xchg operations that I used to attempt to attomically
  update struct pid, because of the strange locking used in the SAK processing.
  With SAK using the normal console semaphore nothing special is needed.

Subject: [PATCH 1570/1971] [PATCH] sysctl_{,ms_}jiffies: fix oldlen semantics

currently it's
1) if *oldlenp == 0,
	don't writeback anything

2) if *oldlenp >= table->maxlen,
	don't writeback more than table->maxlen bytes and rewrite *oldlenp
	don't look at underlying type granularity

3) if 0 < *oldlenp < table->maxlen,
		*cough*
	string sysctls don't writeback more than *oldlenp bytes.
	OK, that's because sizeof(char) == 1

	int sysctls writeback anything in (0, table->maxlen] range
	Though accept integers divisible by sizeof(int) for writing.

sysctl_jiffies and sysctl_ms_jiffies don't writeback anything but
sizeof(int), which violates 1) and 2).

So, make sysctl_jiffies and sysctl_ms_jiffies accept
a) *oldlenp == 0, not doing writeback
b) *oldlenp >= sizeof(int), writing one integer.

-EINVAL still returned for *oldlenp == 1, 2, 3.

Subject: [PATCH 1574/1971] [PATCH] disable init/initramfs.c

The file init/initramfs.c is always compiled and linked in the kernel
vmlinux even when BLK_DEV_RAM and BLK_DEV_INITRD are disabled and the
system isn't using any form of an initramfs or initrd.  In this situation
the code is only used to unpack a (static) default initial rootfilesystem.
The current init/initramfs.c code.  usr/initramfs_data.o compiles to a size
of ~15 kbytes.  Disabling BLK_DEV_RAM and BLK_DEV_INTRD shrinks the kernel
code size with ~60 Kbytes.

This patch avoids compiling in the code and data for initramfs support if
CONFIG_BLK_DEV_INITRD is not defined.  Instead of the initramfs code and
data it uses a small routine in init/noinitramfs.c to setup an initial
static default environment for mounting a rootfilesystem later on in the
kernel initialisation process.  The new code is: 164 bytes of size.

The patch is separated in two parts:
1) doesn't compile initramfs code when CONFIG_BLK_DEV_INITRD is not set
2) changing all plaforms vmlinux.lds.S files to not reserve an area of
PAGE_SIZE when CONFIG_BLK_DEV_INITRD is not set.

Subject: [PATCH 1576/1971] [PATCH] usr/gen_init_cpio.c: support for hard links

Extend usr/gen_init_cpio.c "file" entry, adding support for hard links.

Previous format:
file <name> <location> <mode> <uid> <gid>

New format:
file <name> <location> <mode> <uid> <gid> [<hard links>]

The hard links specification is optional, keeping the previous
behaviour.

All hard links are defined sequentially in the resulting cpio and the
file data is present only in the last link. This is the behaviour of
GNU's cpio and is supported by the kernel initramfs extractor.

Subject: [PATCH 1579/1971] [PATCH] struct vfsmount: keep mnt_count &
 mnt_expiry_mark away from mnt_flags

I noticed cache misses in touch_atime() that can be avoided if we keep
mnt_count & mnt_expiry_mark in a different cache line than mnt_flags
(mostly read)

mnt_count & mnt_expiry_mark are modified each time a file is opened/closed
in a file system.

touch_atime() is called each time a file is read, and generally needs to
read mnt_flags.

Other fields of struct vfsmount are mostly read so I chose to move
mnt_count & mnt_expiry_mark at the end of struct vfsmount.  And adding a
comment so that nobody tries to re-arrange fields to fill the holes :)

On 64bits platforms, the new offsetof(mnt_count) is 0xC0
On 32bits platforms, it is 0x60, so I didnot add a
____cacheline_aligned_in_smp because it would have a too big impact on the
size of this object (in particular if CONFIG_X86_L1_CACHE_SHIFT=7)

This new macro is then used in touch_atime() instead of separatly testing
MS_RDONLY and MS_NOATIME

From: Jarek Poplawski <jarkao2@o2.pl>
Date: Sat, 10 Feb 2007 01:44:58 -0800
Subject: [PATCH 1591/1971] [PATCH] lockdep: more unlock-on-error fixes

- returns after DEBUG_LOCKS_WARN_ON added in 3 places

- debug_locks checking after lookup_chain_cache() added in
  __lock_acquire()

- locking for testing and changing global variable max_lockdep_depth
  added in __lock_acquire()

From: Ingo Molnar <mingo@elte.hu>

My __acquire_lock() cleanup introduced a locking bug: on SMP systems we'd
release a non-owned graph lock.  Fix this by moving the graph unlock back,
and by leaving the max_lockdep_depth variable update possibly racy.  (we
dont care, it's just statistics)

Also add some minimal debugging code to graph_unlock()/graph_lock(),
which caught this locking bug.

Subject: [PATCH 1592/1971] [PATCH] lockdep: add graph depth information to
 /proc/lockdep

Generate locking graph information into /proc/lockdep, for lock hierarchy
documentation and visualization purposes.

sample output:

 c089fd5c OPS:     138 FD:   14 BD:    1 --..: &tty->termios_mutex
  -> [c07a3430] tty_ldisc_lock
  -> [c07a37f0] &port_lock_key
  -> [c07afdc0] &rq->rq_lock_key#2

The lock classes listed are all the first-hop lock dependencies that
lockdep has seen so far.

Subject: [PATCH 1593/1971] [PATCH] igrab() should check for I_CLEAR

When igrab() is calling __iget() on an inode it should check if
clear_inode() has been called on the inode already.  Otherwise there is a
race window between clear_inode() and destroy_inode() where igrab() calls
__iget() which leads to already free inodes on the inode lists.

Subject: [PATCH 1594/1971] [PATCH] consolidate line discipline number
 definitions

The line discipline numbers N_* are currently defined for each architecture
individually, but (except for a seeming mistake) identically, in
asm/termios.h.  There is no obvious reason why these numbers should be
architecture specific, nor any apparent relationship with the termios
structure.  The total number of these, NR_LDISCS, is defined in linux/tty.h
anyway.  So I propose the following patch which moves the definitions of
the individual line disciplines to linux/tty.h too.

Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
in the current kernel, but the patch still keeps the complete set in case
there are plans to use them yet.

Subject: [PATCH 1595/1971] [PATCH] scrub non-__GLIBC__ checks in
 linux/socket.h and linux/stat.h

Userspace should be worrying about userspace, so having the socket.h
and stat.h pollute the namespace in the non-glibc case is wrong and
pretty much prevents any other libc from utilizing these headers
sanely unless they set up the __GLIBC__ define themselves (which
sucks)

Subject: [PATCH 1599/1971] [PATCH] Relay: add CPU hotplug support

Mathieu originally needed to add this for tracing Xen, but it's something
that's needed for any application that can be tracing while cpus are added.

unplug isn't supported by this patch.  The thought was that at minumum a new
buffer needs to be added when a cpu comes up, but it wasn't worth the effort
to remove buffers on cpu down since they'd be freed soon anyway when the
channel was closed.

From d8adb9cef7e406a9a82881695097c702bc98422f Mon Sep 17 00:00:00 2001

Date: Sat, 10 Feb 2007 01:45:06 -0800
Subject: [PATCH 1600/1971] [PATCH] ext2: skip pages past number of blocks in
 ext2_find_entry

This one was pointed out on the MOKB site:
http://kernelfun.blogspot.com/2006/11/mokb-09-11-2006-linux-26x-ext2checkpage.html

If a directory's i_size is corrupted, ext2_find_entry() will keep
processing pages until the i_size is reached, even if there are no more
blocks associated with the directory inode.  This patch puts in some
minimal sanity-checking so that we don't keep checking pages (and issuing
errors) if we know there can be no more data to read, based on the block
count of the directory inode.

This is somewhat similar in approach to the ext3 patch I sent earlier this
year.

Subject: [PATCH 1607/1971] [PATCH] PNP: export pnp_bus_type

The PNP framework doesn't export "pnp_bus_type", which is an unfortunate
exception to the policy followed by pretty much every other bus.  I noticed
this when I had to find a device in order to provide its platform_data.

Note that per advice from Arjan, the "export" scope has been been minimized to
avoid the hundred-plus bytes needed to support access from modules.  In this
case, the symbol is only needed by statically linked kernel code that lives
outside the drivers/pnp directory.

Avoid oopsing when stress-testing open/close -- port->tty is NULL sometimes,
but is expected to be non-NULL, since dereferencing.  Receive/transmit chars
iff ASYNC_CLOSING is not set and ASYNC_INITIALIZED is set.  Thanks Sergei for
pointing this out and testing.

Subject: [PATCH 1616/1971] [PATCH] Char: mxser_new, fix twice resource
 releasing

Because brd->info is not NULLed, resources are released twice.  NULL it in
pci_remove function.  Also take care of retval and releasing in pci_probe --
mxser_initbrd alreasy releases resource, do not do it again in fail path in
probe function.

Subject: [PATCH 1619/1971] [PATCH] Char: mxser_new, do not null driver_data

driver_data are initialzed to NULL from tty layer, no need to do it in the
driver.  In this case it cases oops, since driver_data may be NULL for a short
while for another closing process.

Subject: [PATCH 1622/1971] [PATCH] Add TAINT_USER and ability to set taint
 flags from userspace

Allow taint flags to be set from userspace by writing to
/proc/sys/kernel/tainted, and add a new taint flag, TAINT_USER, to be used
when userspace has potentially done something dangerous that might
compromise the kernel.  This will allow support personnel to ask further
questions about what may have caused the user taint flag to have been set.

For example, they might examine the logs of the realtime JVM to see if the
Java program has used the really silly, stupid, dangerous, and
completely-non-portable direct access to physical memory feature which MUST
be implemented according to the Real-Time Specification for Java (RTSJ).
Sigh.  What were those silly people at Sun thinking?

Subject: [PATCH 1625/1971] [PATCH] Char: moxa, timers cleanup

Use kernel macros and functions for timer encapsulation -- do not access
fileds directly.  Also del_timer on inactive is legal, so that noting if it
runs is senseless, delete these variables.

There is more possible solutions for this problem.

It makes no sense to me to export invalidate_inode_pages() and not
invalidate_mapping_pages() and I actually need invalidate_mapping_pages()
because of its range specification ability...

akpm: also remove the export of invalidate_inode_pages() by making it an
inlined wrapper.

Subject: [PATCH 1642/1971] [PATCH] use cycle_t instead of u64 in struct
 time_interpolator

The 32bit and 64bit PARISC Linux kernels suffers from the problem, that the
gettimeofday() call sometimes returns non-monotonic times.

The easiest way to fix this, is to drop the PARISC-specific implementation
and switch over to the generic TIME_INTERPOLATION framework.

But in order to make it even compile on 32bit PARISC, the patch below which
touches the generic Linux code, is mandatory.

More information and the full patch with the parisc-specific changes is included in this thread: http://lists.parisc-linux.org/pipermail/parisc-linux/2006-December/031003.html

As far as I could see, this patch does not change anything for the existing
architectures which use this framework (IA64 and SPARC64), since "cycles_t"
is defined there as unsigned 64bit-integer anyway (which then makes this
patch a no-change for them).

Subject: [PATCH 1644/1971] [PATCH] add an RCU version of list splicing

This patch is in support of the IPMI driver.  I have tested this with the
IPMI driver changes coming in the next patch.

Add a list_splice_init_rcu() function to splice an RCU-protected list into
another list.  This takes the sync function as an argument, so one would do
something like:

	INIT_LIST_HEAD(&list);
	list_splice_init_rcu(&source, &dest, synchronize_rcu);

The idea being to keep the RCU API proliferation down to a dull roar.

Subject: [PATCH 1645/1971] [PATCH] IPMI: Fix some RCU problems

Fix some RCU problem pointed out by Paul McKenney of IBM.  These are:

The wholesale move of the command receivers list into a new list was not
safe because the list will point to the new tail during a traversal, so the
traversal will never end on a reader if this happens during a read.

Memory barriers were needed to handle proper ordering of the setting of the
IPMI interface as valid.  Readers might not see proper ordering of data
otherwise.

In ipmi_smi_watcher_register(), the use of the _rcu suffix on the list is
unnecessary.

This require the list_splice_init_rcu() patch previously posted.

Subject: [PATCH 1647/1971] [PATCH] relax check for AIX in msdos partition
 table

The patch to identify AIX disks and ignore them has caused at least one
machine to fail to find the root partition on 2.6.19. The patch is:

http://lkml.org/lkml/2006/7/31/117

The problem is some disk formatters do not blow away the first 4 bytes
of the disk. If the disk we are installing to used to have AIX on it,
then the first 4 bytes will still have IBMA in EBCDIC.

The install in question was debian etch. Im not sure what the best fix
is, perhaps the AIX detection code could check more than the first 4
bytes.

The whole partition info for primary partitions is in this block:

  dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be ))

All other data do not matter, beside the 0x55aa marker at the end of the
first block.

Subject: [PATCH 1654/1971] [PATCH] kernel-doc: allow a little whitespace

In kernel-doc syntax, be a little flexible:  allow whitespace between
a function parameter name and the colon that must follow it, such as:
	@pdev : PCI device to unplug

(This allows lots of megaraid kernel-doc to work without tons of
editing.)

Subject: [PATCH 1655/1971] [PATCH] proc: remove useless (and buggy) ->nlink
 settings

Bug: pnx8550 code creates directory but resets ->nlink to 1.

create_proc_entry() et al will correctly set ->nlink for you.

Subject: [PATCH 1658/1971] [PATCH] tty: improve encode_baud_rate logic

Mostly so people can see the work in progress.  This enhances the encode
function which isn't currently used in the base tree but is when using some of
the testing tty patches.

This resolves a problem with some hardware where applications got confusing
information from the tty ioctls.  Correct but confusing.

In some situations asking for, say, 9600 baud actually gets you 9595 baud or
similar near-miss values.  With the old code this meant that a request for
B9600 got a return of BOTHER, 9595 which programs interpreted as a failure.

The new code now works on the following basis

- If you ask for specific rate via BOTHER, you get a precise return

- If you ask for a standard Bfoo rate and the result is close you get a Bfoo
  return

- If you ask for a standard Bfoo rate and get something way off you get a
  BOTHER/rate return

This seems to fix up the cases I've found where this broke compatibility.

From d4d23add3abcd18d8021b99f230df608ccb2f007 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1661/1971] [PATCH] Common compat_sys_sysinfo

I noticed that almost all architectures implemented exactly the same
sys32_sysinfo...  except parisc, where a bug was to be found in handling of
the uptime.  So let's remove a whole whack of code for fun and profit.
Cribbed compat_sys_sysinfo from x86_64's implementation, since I figured it
would be the best tested.

This patch incorporates Arnd's suggestion of not using set_fs/get_fs, but
instead extracting out the common code from sys_sysinfo.

+	     Semantics and Behavior of Local Atomic Operations
+
+			    Mathieu Desnoyers
+
+
+	This document explains the purpose of the local atomic operations, how
+to implement them for any given architecture and shows how they can be used
+properly. It also stresses on the precautions that must be taken when reading
+those local variables across CPUs when the order of memory writes matters.
+
+
+
+* Purpose of local atomic operations
+
+Local atomic operations are meant to provide fast and highly reentrant per CPU
+counters. They minimize the performance cost of standard atomic operations by
+removing the LOCK prefix and memory barriers normally required to synchronize
+across CPUs.
+
+Having fast per CPU atomic counters is interesting in many cases : it does not
+require disabling interrupts to protect from interrupt handlers and it permits
+coherent counters in NMI handlers. It is especially useful for tracing purposes
+and for various performance monitoring counters.
+
+Local atomic operations only guarantee variable modification atomicity wrt the
+CPU which owns the data. Therefore, care must taken to make sure that only one
+CPU writes to the local_t data. This is done by using per cpu data and making
+sure that we modify it from within a preemption safe context. It is however
+permitted to read local_t data from any CPU : it will then appear to be written
+out of order wrt other memory writes on the owner CPU.
+
+
+* Implementation for a given architecture
+
+It can be done by slightly modifying the standard atomic operations : only
+their UP variant must be kept. It typically means removing LOCK prefix (on
+i386 and x86_64) and any SMP sychronization barrier. If the architecture does
+not have a different behavior between SMP and UP, including asm-generic/local.h
+in your archtecture's local.h is sufficient.
+
+The local_t type is defined as an opaque signed long by embedding an
+atomic_long_t inside a structure. This is made so a cast from this type to a
+long fails. The definition looks like :
+
+typedef struct { atomic_long_t a; } local_t;
+
+
+* How to use local atomic operations
+
+#include <linux/percpu.h>
+#include <asm/local.h>
+
+static DEFINE_PER_CPU(local_t, counters) = LOCAL_INIT(0);
+
+
+* Counting
+
+Counting is done on all the bits of a signed long.
+
+In preemptible context, use get_cpu_var() and put_cpu_var() around local atomic
+operations : it makes sure that preemption is disabled around write access to
+the per cpu variable. For instance :
+
+	local_inc(&get_cpu_var(counters));
+	put_cpu_var(counters);
+
+If you are already in a preemption-safe context, you can directly use
+__get_cpu_var() instead.
+
+	local_inc(&__get_cpu_var(counters));
+
+
+
+* Reading the counters
+
+Those local counters can be read from foreign CPUs to sum the count. Note that
+the data seen by local_read across CPUs must be considered to be out of order
+relatively to other memory writes happening on the CPU that owns the data.
+
+	long sum = 0;
+	for_each_online_cpu(cpu)
+		sum += local_read(&per_cpu(counters, cpu));
+
+If you want to use a remote local_read to synchronize access to a resource
+between CPUs, explicit smp_wmb() and smp_rmb() memory barriers must be used
+respectively on the writer and the reader CPUs. It would be the case if you use
+the local_t variable as a counter of bytes written in a buffer : there should
+be a smp_wmb() between the buffer write and the counter increment and also a
+smp_rmb() between the counter read and the buffer read.
+
+
+Here is a sample module which implements a basic per cpu counter using local.h.
+
+--- BEGIN ---
+/* test-local.c
+ *
+ * Sample module for local.h usage.
+ */
+

+#include <linux/module.h>
+#include <linux/timer.h>
+
+static DEFINE_PER_CPU(local_t, counters) = LOCAL_INIT(0);
+
+static struct timer_list test_timer;
+
+/* IPI called on each CPU. */
+static void test_each(void *info)
+{
+	/* Increment the counter from a non preemptible context */
+	printk("Increment on cpu %d\n", smp_processor_id());
+	local_inc(&__get_cpu_var(counters));
+
+	/* This is what incrementing the variable would look like within a
+	 * preemptible context (it disables preemption) :
+	 *
+	 * local_inc(&get_cpu_var(counters));
+	 * put_cpu_var(counters);
+	 */
+}
+
+static void do_test_timer(unsigned long data)
+{
+	int cpu;
+
+	/* Increment the counters */
+	on_each_cpu(test_each, NULL, 0, 1);
+	/* Read all the counters */
+	printk("Counters read from CPU %d\n", smp_processor_id());
+	for_each_online_cpu(cpu) {
+		printk("Read : CPU %d, count %ld\n", cpu,
+			local_read(&per_cpu(counters, cpu)));
+	}
+	del_timer(&test_timer);

Subject: [PATCH 1663/1971] [PATCH] RTC framework driver for CMOS RTCs

This is an "RTC framework" driver for the "CMOS" RTCs which are standard on
PCs and some other platforms.  That's MC146818 compatible silicon.
Advantages of this vs.  drivers/char/rtc.c (use one _or_ the other, only
one will be able to claim the RTC irq) include:

 - This leverages both the new RTC framework and the driver model; both
   PNPACPI and platform device modes are supported.  (A separate patch
   creates a platform device on PCs where PNPACPI isn't configured.)

 - It supports common extensions like longer alarms.  (A separate patch
   exports that information from ACPI through platform_data.)

 - Likewise, system wakeup events use "real driver model support", with
   policy control via sysfs "wakeup" attributes and and using normal rtc
   ioctls to manage wakeup.  (Patch in the works.  The ACPI hooks are
   known; /proc/acpi/alarm can vanish.  Making it work with EFI will
   be a minor challenge to someone with e.g. a MiniMac.)

It's not yet been tested on non-x86 systems, without ACPI, or with HPET.
And the RTC framework will surely have teething pains on "mainstream"
PC-based systems (though must embedded Linux systems use it heavily), not
limited to sorting out the "/dev/rtc0" issue (udev easily tweaked).  Also,
the ALSA rtctimer code doesn't use the new RTC API.

Otherwise, this should be a no-known-regressions replacement for the old
drivers/char/rtc.c driver, and should help the non-embedded distros (and
the new timekeeping code) start to switch to the framework.

Note also that any systems using "rtc-m48t86" are candidates to switch over
to this more functional driver; the platform data is different, and the way
bytes are read is different, but otherwise those chips should be compatible.

Subject: [PATCH 1665/1971] [PATCH] kernel-doc: fix some odd spacing issues

- in man and text mode output, if the function return type is empty (like it
  is for macros), don't print the return type and a following space; this
  fixes an output malalignment;

- in the function short description, strip leading, trailing, and multiple
  embedded spaces (to one space); this makes function name/description output
  spacing consistent;

- fix a comment typo;

In the rare case where we have skipped orphan inode processing due to a
readonly block device, and the block device subsequently changes back to
read-write, disallow a remount,rw transition of the filesystem when we have an
unprocessed orphan inodes as this would corrupt the list.

Ideally we should process the orphan inode list during the remount, but that's
trickier, and this plugs the hole for now.

Subject: [PATCH 1671/1971] [PATCH] audit: fix audit_filter_user_rules()
 initialization bug

gcc emits this warning:

 kernel/auditfilter.c: In function 'audit_filter_user':
 kernel/auditfilter.c:1611: warning: 'state' is used uninitialized in this function

I tend to agree with gcc - there are a couple of plausible exit paths from
audit_filter_user_rules() where it does not set 'state', keeping the
variable uninitialized.  For example if a filter rule has an AUDIT_POSSIBLE
action.  Initialize to 'wont audit'.  Fix whitespace damage too.

Subject: [PATCH 1672/1971] [PATCH] raw: don't allow the creation of a raw
 device with minor number 0

Minor number 0 (under the raw major) is reserved for the rawctl device
file, which is used to query, set, and unset raw device bindings.  However,
the ioctl interface does not protect the user from specifying a raw device
with minor number 0:

$ sudo ./raw /dev/raw/raw0 /dev/VolGroup00/swap
/dev/raw/raw0:  bound to major 253, minor 2
$ ls -l /dev/rawctl
ls: /dev/rawctl: No such file or directory
$ ls -l /dev/raw/raw0
crw------- 1 root root 162, 0 Jan 12 10:51 /dev/raw/raw0
$ sudo ./raw -qa
Cannot open master raw device '/dev/rawctl' (No such file or directory)

As you can see, this prevents any further raw operations from
succeeding.  The fix (from Steve Fernandez) is quite simple--do not
allow the allocation of minor number 0.

Subject: [PATCH 1673/1971] [PATCH] sn2: use static ->proc_fops

fix-rmmod-read-write-races-in-proc-entries.patch doesn't want dynamically
allocated ->proc_fops, because it will set it to NULL at module unload time.

Regardless of module status, switch to statically allocated ->proc_fops which
leads to simpler code without wrappers.

AFAICS, also fix the following bug: "sn_force_interrupt" proc entry set
->write for itself, but was created with 0444 permissions. Change to 0644.

Subject: [PATCH 1675/1971] [PATCH] fix umask when noACL kernel meets extN
 tuned for ACLs

Fix insecure default behaviour reported by Tigran Aivazian: if an ext2 or
ext3 or ext4 filesystem is tuned to mount with "acl", but mounted by a
kernel built without ACL support, then umask was ignored when creating
inodes - though root or user has umask 022, touch creates files as 0666,
and mkdir creates directories as 0777.

This appears to have worked right until 2.6.11, when a fix to the default
mode on symlinks (always 0777) assumed VFS applies umask: which it does,
unless the mount is marked for ACLs; but ext[234] set MS_POSIXACL in
s_flags according to s_mount_opt set according to def_mount_opts.

We could revert to the 2.6.10 ext[234]_init_acl (adding an S_ISLNK test);
but other filesystems only set MS_POSIXACL when ACLs are configured.  We
could fix this at another level; but it seems most robust to avoid setting
the s_mount_opt flag in the first place (at the expense of more ifdefs).

Likewise don't set the XATTR_USER flag when built without XATTR support.

Return -ENOENT from ext[34]_link if we've raced with unlink and i_nlink is
0.  Doing otherwise has the potential to corrupt the orphan inode list,
because we'd wind up with an inode with a non-zero link count on the list,
and it will never get properly cleaned up & removed from the orphan list
before it is freed.

Since then, m32r grabbed two copies.

Leave s390 copy because of important absence of CONFIG_VT, but remove
references to non-existent timerlist_lock.  ia64 also loses timerlist_lock.

Subject: [PATCH 1682/1971] [PATCH] extend the set of "__attribute__" shortcut
 macros

Extend the set of "__attribute__" shortcut macros, and remove identical
(and now superfluous) definitions from a couple of source files.

based on a page at robert love's blog:

	http://rlove.org/log/2005102601

extend the set of shortcut macros defined in compiler-gcc.h with the
following:

#define __packed                       __attribute__((packed))
#define __weak                         __attribute__((weak))
#define __naked                        __attribute__((naked))
#define __noreturn                     __attribute__((noreturn))
#define __pure                         __attribute__((pure))
#define __aligned(x)                   __attribute__((aligned(x)))
#define __printf(a,b)                  __attribute__((format(printf,a,b)))

Once these are in place, it's up to subsystem maintainers to decide if they
want to take advantage of them.  there is already a strong precedent for
using shortcuts like this in the source tree.

The ones that might give people pause are "__aligned" and "__printf", but
shortcuts for both of those are already in use, and in some ways very
confusingly.  note the two very different definitions for a macro named
"ALIGNED":

  drivers/net/sgiseeq.c:#define ALIGNED(x) ((((unsigned long)(x)) + 0xf) & ~(0xf))
  drivers/scsi/ultrastor.c:#define ALIGNED(x) __attribute__((aligned(x)))

also:

  include/acpi/platform/acgcc.h:
    #define ACPI_PRINTF_LIKE(c) __attribute__ ((__format__ (__printf__, c, c+1)))

Given the precedent, then, it seems logical to at least standardize on a
consistent set of these macros.

+Red-black Trees (rbtree) in Linux
+January 18, 2007
+Rob Landley <rob@landley.net>
+=============================
+
+What are red-black trees, and what are they for?
+------------------------------------------------
+
+Red-black trees are a type of self-balancing binary search tree, used for
+storing sortable key/value data pairs.  This differs from radix trees (which
+are used to efficiently store sparse arrays and thus use long integer indexes
+to insert/access/delete nodes) and hash tables (which are not kept sorted to
+be easily traversed in order, and must be tuned for a specific size and
+hash function where rbtrees scale gracefully storing arbitrary keys).
+
+Red-black trees are similar to AVL trees, but provide faster real-time bounded
+worst case performance for insertion and deletion (at most two rotations and
+three rotations, respectively, to balance the tree), with slightly slower
+(but still O(log n)) lookup time.
+
+To quote Linux Weekly News:
+
+    There are a number of red-black trees in use in the kernel.
+    The anticipatory, deadline, and CFQ I/O schedulers all employ
+    rbtrees to track requests; the packet CD/DVD driver does the same.
+    The high-resolution timer code uses an rbtree to organize outstanding
+    timer requests.  The ext3 filesystem tracks directory entries in a
+    red-black tree.  Virtual memory areas (VMAs) are tracked with red-black
+    trees, as are epoll file descriptors, cryptographic keys, and network
+    packets in the "hierarchical token bucket" scheduler.
+
+This document covers use of the Linux rbtree implementation.  For more
+information on the nature and implementation of Red Black Trees,  see:
+
+  Linux Weekly News article on red-black trees
+    http://lwn.net/Articles/184495/
+
+  Wikipedia entry on red-black trees
+    http://en.wikipedia.org/wiki/Red-black_tree
+
+Linux implementation of red-black trees
+---------------------------------------
+
+Linux's rbtree implementation lives in the file "lib/rbtree.c".  To use it,
+"#include <linux/rbtree.h>".
+
+The Linux rbtree implementation is optimized for speed, and thus has one
+less layer of indirection (and better cache locality) than more traditional
+tree implementations.  Instead of using pointers to separate rb_node and data
+structures, each instance of struct rb_node is embedded in the data structure
+it organizes.  And instead of using a comparison callback function pointer,
+users are expected to write their own tree search and insert functions
+which call the provided rbtree functions.  Locking is also left up to the
+user of the rbtree code.
+
+Creating a new rbtree
+---------------------
+
+Data nodes in an rbtree tree are structures containing a struct rb_node member:
+
+  struct mytype {
+  	struct rb_node node;
+  	char *keystring;
+  };
+
+When dealing with a pointer to the embedded struct rb_node, the containing data
+structure may be accessed with the standard container_of() macro.  In addition,
+individual members may be accessed directly via rb_entry(node, type, member).
+
+At the root of each rbtree is an rb_root structure, which is initialized to be
+empty via:
+
+  struct rb_root mytree = RB_ROOT;
+
+Searching for a value in an rbtree
+----------------------------------
+
+Writing a search function for your tree is fairly straightforward: start at the
+root, compare each value, and follow the left or right branch as necessary.
+
+Example:
+
+  struct mytype *my_search(struct rb_root *root, char *string)
+  {
+  	struct rb_node *node = root->rb_node;
+
+  	while (node) {
+  		struct mytype *data = container_of(node, struct mytype, node);
+		int result;
+
+		result = strcmp(string, data->keystring);
+
+		if (result < 0)
+  			node = node->rb_left;
+		else if (result > 0)
+  			node = node->rb_right;
+		else
+  			return data;
+	}
+	return NULL;
+  }
+
+Inserting data into an rbtree
+-----------------------------
+
+Inserting data in the tree involves first searching for the place to insert the
+new node, then inserting the node and rebalancing ("recoloring") the tree.
+
+The search for insertion differs from the previous search by finding the
+location of the pointer on which to graft the new node.  The new node also
+needs a link to its parent node for rebalancing purposes.
+
+Example:
+
+  int my_insert(struct rb_root *root, struct mytype *data)
+  {
+  	struct rb_node **new = &(root->rb_node), *parent = NULL;
+
+  	/* Figure out where to put new node */
+  	while (*new) {
+  		struct mytype *this = container_of(*new, struct mytype, node);
+  		int result = strcmp(data->keystring, this->keystring);
+
+		parent = *new;
+  		if (result < 0)
+  			new = &((*new)->rb_left);
+  		else if (result > 0)
+  			new = &((*new)->rb_right);
+  		else
+  			return FALSE;
+  	}
+
+  	/* Add new node and rebalance tree. */
+  	rb_link_node(data->node, parent, new);
+  	rb_insert_color(data->node, root);
+
+	return TRUE;
+  }
+
+Removing or replacing existing data in an rbtree
+------------------------------------------------
+
+To remove an existing node from a tree, call:
+
+  void rb_erase(struct rb_node *victim, struct rb_root *tree);
+
+Example:
+
+  struct mytype *data = mysearch(mytree, "walrus");
+
+  if (data) {
+  	rb_erase(data->node, mytree);
+  	myfree(data);
+  }
+
+To replace an existing node in a tree with a new one with the same key, call:
+
+  void rb_replace_node(struct rb_node *old, struct rb_node *new,
+  			struct rb_root *tree);
+
+Replacing a node this way does not re-sort the tree: If the new node doesn't
+have the same key as the old node, the rbtree will probably become corrupted.
+
+Iterating through the elements stored in an rbtree (in sort order)
+------------------------------------------------------------------
+
+Four functions are provided for iterating through an rbtree's contents in
+sorted order.  These work on arbitrary trees, and should not need to be
+modified or wrapped (except for locking purposes):
+
+  struct rb_node *rb_first(struct rb_root *tree);
+  struct rb_node *rb_last(struct rb_root *tree);
+  struct rb_node *rb_next(struct rb_node *node);
+  struct rb_node *rb_prev(struct rb_node *node);
+
+To start iterating, call rb_first() or rb_last() with a pointer to the root
+of the tree, which will return a pointer to the node structure contained in
+the first or last element in the tree.  To continue, fetch the next or previous
+node by calling rb_next() or rb_prev() on the current node.  This will return
+NULL when there are no more nodes left.
+
+The iterator functions return a pointer to the embedded struct rb_node, from
+which the containing data structure may be accessed with the container_of()
+macro, and individual members may be accessed directly via
+rb_entry(node, type, member).
+
+Example:
+
+  struct rb_node *node;
+  for (node = rb_first(&mytree); node; node = rb_next(node))
+  	printk("key=%s\n", rb_entry(node, int, keystring));
+

Date: Sat, 10 Feb 2007 01:46:22 -0800
Subject: [PATCH 1684/1971] [PATCH] buffer: memorder fix

unlock_buffer(), like unlock_page(), must not clear the lock without
ensuring that the critical section is closed.

Mingming later sent the same patch, saying:

  We are running SDET benchmark and saw double free issue for ext3 extended
  attributes block, which complains the same xattr block already being freed (in
  ext3_xattr_release_block()).  The problem could also been triggered by
  multiple threads loop untar/rm a kernel tree.

  The race is caused by missing a memory barrier at unlock_buffer() before the
  lock bit being cleared, resulting in possible concurrent h_refcounter update.
  That causes a reference counter leak, then later leads to the double free that
  we have seen.

  Inside unlock_buffer(), there is a memory barrier is placed *after* the lock
  bit is being cleared, however, there is no memory barrier *before* the bit is
  cleared.  On some arch the h_refcount update instruction and the clear bit
  instruction could be reordered, thus leave the critical section re-entered.

  The race is like this: For example, if the h_refcount is initialized as 1,

  cpu 0:                                   cpu1
  --------------------------------------   -----------------------------------
  lock_buffer() /* test_and_set_bit */
  clear_buffer_locked(bh);
                                          lock_buffer() /* test_and_set_bit */
  h_refcount = h_refcount+1; /* = 2*/     h_refcount = h_refcount + 1; /*= 2 */
                                          clear_buffer_locked(bh);
  ....                                    ......

  We lost a h_refcount here. We need a memory barrier before the buffer head lock
  bit being cleared to force the order of the two writes.  Please apply.

Subject: [PATCH 1693/1971] [PATCH] order of lockdep off/on in vprintk() should
 be changed

The order of locking between lockdep_off/on() and local_irq_save/restore() in
vprintk() should be changed.

* In kernel/printk.c :

vprintk() does :

preempt_disable()
local_irq_save()
lockdep_off()
spin_lock(&logbuf_lock)
spin_unlock(&logbuf_lock)
if(!down_trylock(&console_sem))
   up(&console_sem)
lockdep_on()
local_irq_restore()
preempt_enable()

The goals here is to make sure we do not call printk() recursively from
kernel/lockdep.c:__lock_acquire() (called from spin_* and down/up) nor from
kernel/lockdep.c:trace_hardirqs_on/off() (called from local_irq_restore/save).
It can then potentially call printk() through mark_held_locks/mark_lock.

It correctly protects against the spin_lock call and the up/down call, but it
does not protect against local_irq_restore. It could cause infinite recursive
printk/trace_hardirqs_on() calls when printk() is called from the
mark_lock() error handing path.

We should change the locking so it becomes correct :

preempt_disable()
lockdep_off()
local_irq_save()
spin_lock(&logbuf_lock)
spin_unlock(&logbuf_lock)
if(!down_trylock(&console_sem))
   up(&console_sem)
local_irq_restore()
lockdep_on()
preempt_enable()

Subject: [PATCH 1694/1971] [PATCH] some rtc documentation updates

Fix typo when describing RTC_WKALM.  Add some helpful pointers to people
developing their own RTC driver.  Change a bunch of the error messages in the
test program to be a bit more helpful.

+	will be set to proper values when using WKALM.
+
+    *	RTC_IRQP_SET, RTC_IRQP_READ: the irq_set_freq function will be called

+	initialization routines so the framework can sanity check the user
+	input for you.

Catch illegally nested kmap_atomic()s even if the page that is mapped by
the 'inner' instance is from lowmem.

This avoids spuriously zapped kmap-atomic ptes and turns hard to find
crashes into clear asserts at the bug site.

Subject: [PATCH 1701/1971] [PATCH] Fix sparse annotation of spin unlock macros
 in one case

SMP systems without premption and spinlock debugging enabled use unlock
macros that don't tell sparse that the lock is being released.  Add sparse
annotations in this case.

Subject: [PATCH 1702/1971] [PATCH] _proc_do_string(): fix short reads

If you try to read things like /proc/sys/kernel/osrelease with single-byte
reads, you get just one byte and then EOF.  This is because _proc_do_string()
assumes that the caller is read()ing into a buffer which is large enough to
fit the whole string in a single hit.

Fix.

They are fat: 4x8 bytes in task_struct.
They are uncoditionally updated in every fork, read, write and sendfile.
They are used only if you have some "extended acct fields feature".

And please, please, please, read(2) knows about bytes, not characters,
why it is called "rchar"?

Subject: [PATCH 1705/1971] [PATCH] tty: cleanup release_mem

release_mem contains two copies of exactly the same code.  Refactor these
into a new helper, release_tty.  The only change in behaviour is that the
driver reference count is now decremented after the master tty has been
freed instead of before.

Subject: [PATCH 1706/1971] [PATCH] rapidio: fix multi-switch enumeration

This patch contains two fixes for RapisIO enumeration logic:

1. Fix enumeration in configurations with multiple switches. The patch adds:

   a. Enumeration of an empty switch.  Empty switch is a switch that
      does not have any endpoint devices attached to it (except host device
      or previous switch in a chain).  New code assigns a phony destination
      ID associated with the switch and sets up corresponding routes.

   b. Adds a second pass to the enumeration to setup routes to
      devices discovered after switch was scanned.

2. Fix enumeration failure when riohdid parameter has non-zero value.
   Current version fails to setup response path to the host when it has
   destination ID other that 0.

* Split the implementation-agnostic stuff in separate files.
* Make sure that targets using non-default request_irq() pull
  kernel/irq/devres.o
* Introduce new symbols (HAS_IOPORT and HAS_IOMEM) defaulting to positive;
  allow architectures to turn them off (we needed these symbols anyway for
  dependencies of quite a few drivers).
* protect the ioport-related parts of lib/devres.o with CONFIG_HAS_IOPORT.

Date: Sun, 11 Feb 2007 18:15:29 +0000
Subject: [PATCH 1713/1971] [PATCH] Switch s390 to NO_IOMEM

Martin Schwidefsky wrote:
  "s390 does not even need (in|out)b(_p|).  I wondered what else from
   io.h do we not need.  The answer is: almost nothing.  With the devres
   patch from Al and the dma-mapping patch from Heiko we can get rid of
   iomem and all associated definitions."

So we'll just need to replace NO_IOPORT with NO_IOMEM in Kconfig and
kill arch/s390/mm/ioremap.c.

BTW, there's an annoying bit of junk in there - IO_SPACE_LIMIT.  We
only need it for /proc/ioports, which AFAICS shouldn't even be there
on s390 (or uml).  OTOH, removing that thing would mean a user-visible
change - we go from "empty file in /proc" to "no such file in /proc"...

advantage. Chance that to service_last, and base the resorter
on that.

Subject: [PATCH 1723/1971] cfq-iosched: account for slice over/under time

If a slice uses less than it is entitled to (or perhaps more), include
that in the decision on how much time to give it the next time it
gets serviced.

Subject: [PATCH 1724/1971] cfq-iosched: don't pass in queue for
 cfq_arm_slice_timer()

It must always be the active queue, otherwise it's a bug. So just
use the active_queue, don't pass it in explicitly.

Subject: [PATCH 1725/1971] cfq-iosched: tweak the FIFO checking

We currently check the FIFO once per slice. Optimize that a bit and
only do it as the first thing for a new slice, so we don't end up
doing a single request and then seek to the FIFO requests.

Subject: [PATCH 1730/1971] [S390] smp_call_function/smp_call_function_on
 locking.

smp_call_function and smp_call_function_on share the same lock and
smp_call_function_on disables softirq's so it can be called from
softirq context as well. Hence smp_call_function muss disable
softirqs as well to avoid deadlocks.

Subject: [PATCH 1731/1971] [S390] cio: Fixup interface for setting options on
 ccw devices.

The current ccw_device_set_options() sets a specified mask of options
and clears those not specified, but there is no way to find out which
options have already been set.

In order to fix this up, introduce the following interface changes:

ccw_device_set_options() now only sets the specified bits, but does
not clear those that are not specified.

ccw_device_clear_options() clears the specified bits.

ccw_device_set_options_mask() provides the old semantics (setting only
the specified bits and clearing the others).

Device drivers now work as expected. qdio has been adapted.

Subject: [PATCH 1738/1971] [PATCH] Make BH_Unwritten a first class bufferhead
 flag V2

Currently, XFS uses BH_PrivateStart for flagging unwritten extent state in a
bufferhead.  Recently, I found the long standing mmap/unwritten extent
conversion bug, and it was to do with partial page invalidation not clearing
the unwritten flag from bufferheads attached to the page but beyond EOF.  See
here for a full explaination:

http://oss.sgi.com/archives/xfs/2006-12/msg00196.html

The solution I have checked into the XFS dev tree involves duplicating code
from block_invalidatepage to clear the unwritten flag from the bufferhead(s),
and then calling block_invalidatepage() to do the rest.

Christoph suggested that this would be better solved by pushing the unwritten
flag into the common buffer head flags and just adding the call to
discard_buffer():

http://oss.sgi.com/archives/xfs/2006-12/msg00239.html

The following patch makes BH_Unwritten a first class citizen.

Subject: [PATCH 1743/1971] [PATCH] Fix d_path for lazy unmounts

Here is a bugfix to d_path.

First, when d_path() hits a lazily unmounted mount point, it tries to
prepend the name of the lazily unmounted dentry to the path name.  It gets
this wrong, and also overwrites the slash that separates the name from the
following pathname component.  This is demonstrated by the attached test
case, which prints "getcwd returned d_path-bugsubdir" with the bug.  The
correct result would be "getcwd returned d_path-bug/subdir".

It could be argued that the name of the root dentry should not be part of
the result of d_path in the first place.  On the other hand, what the
unconnected namespace was once reachable as may provide some useful hints
to users, and so that seems okay.

Second, it isn't always possible to tell from the __d_path result whether
the specified root and rootmnt (i.e., the chroot) was reached: lazy
unmounts of bind mounts will produce a path that does start with a
non-slash so we can tell from that, but other lazy unmounts will produce a
path that starts with a slash, just like "ordinary" paths.

The attached patch cleans up __d_path() to fix the bug with overlapping
pathname components.  It also adds a @fail_deleted argument, which allows
to get rid of some of the mess in sys_getcwd().  Grabbing the dcache_lock
can then also be moved into __d_path().  The patch also makes sure that
paths will only start with a slash for paths which are connected to the
root and rootmnt.

The @fail_deleted argument could be added to d_path() as well: this would
allow callers to recognize deleted files, without having to resort to the
ambiguous check for the " (deleted)" string at the end of the pathnames.
This is not currently done, but it might be worthwhile.

Subject: [PATCH 1749/1971] [PATCH] fix the defaults mentioned in
 Documentation/nfsroot.txt

This patch fixes the documentation of nfsroot to match NFS_DEF_FILE_IO_SIZE.

Or perhaps we need to change NFS_DEF_FILE_IO_SIZE to match the
documentation?

Subject: [PATCH 1751/1971] [PATCH] move remove_dquot_ref to dqout.c

Remove_dquot_ref can move to dqout.c instead of beeing in inode.c under
#ifdef CONFIG_QUOTA.  Also clean the resulting code up a tiny little bit by
testing sb->dq_op earlier - it's constant over a filesystems lifetime.

Subject: [PATCH 1752/1971] [PATCH] remove sb->s_files and file_list_lock usage
 in dquot.c

Iterate over sb->s_inodes instead of sb->s_files in add_dquot_ref.  This
reduces list search and lock hold time aswell as getting rid of one of the
few uses of file_list_lock which Ingo identified as a scalability problem.

Previously we called dq_op->initialize for every inode handing of a
writeable file that wasn't initialized before.  Now we're calling it for
every inode that has a non-zero i_writecount, aka a writeable file
descriptor refering to it.

Thanks a lot to Jan Kara for running this patch through his quota test
harness.

Subject: [PATCH 1753/1971] [PATCH] inotify: read return val fix

Fix for inotify read bug (bugzilla.kernel.org #6999)

Problem Description:
When reading from an inotify device with an insufficient sized buffer, read(2)
will return 0 with no errno set. This is because of an logically incorrect
action from the user program thus should return an more logical value. My
suggestion is return -EINVAL as for bind(2).

This patch is based on the proposal from Ryan <wolf0403@hotmail.com>, and
feedback from John McCutchan <john@johnmccutchan.com>.

Return -EINVAL if we have not passed in enough buffer space to read a single
inotify event, rather than 0 which indicates that there is nothing to read.

Subject: [PATCH 1755/1971] [PATCH] kernel: shut up the IRQ mismatch messages

The problem is various drivers legally validly and sensibly try to claim
IRQs but the kernel insists on vomiting forth a giant irrelevant debugging
spew when the types clash.

Edit kernel/irq/manage.c go down to mismatch: in setup_irq() and ifdef out
the if clause that checks for mismatches.  It'll then just do the right
thing and work sanely.

For the current -mm kernel this will do the trick (and moves it into shared
irq debugging as in debug mode the info spew is useful).  I've had a
variant of this in my private tree for some time as I got fed up on the
mess on boxes where old legacy IRQs get reused.

Subject: [PATCH 1760/1971] [PATCH] ipc: save the ipc namespace while reading
 proc files

The problem we were assuming that current->nsproxy->ipc_ns would never
change while someone has our file in /proc/sysvipc/ file open.  Given that
this can change with both unshare and by passing the file descriptor to
another process that assumption is occasionally wrong.

Therefore this patch causes /proc/sysvipc/* to cache the namespace and
increment it's count when we open the file and to decrement the count when
we close the file, ensuring consistent operation with no surprises.

Subject: [PATCH 1762/1971] [PATCH] atmel_serial: Use __raw I/O register access

Access to chip-internal registers should always be native-endian.  This is
especially important for AVR32 since it's a big-endian architecture and the
non-raw readl() and writel() macros are defined to do little-endian
accesses.

Subject: [PATCH 1767/1971] [PATCH] FS: speed up rw_verify_area()

oprofile hunting showed a stall in rw_verify_area(), because of triple
indirection and potential cache misses.
(file->f_path.dentry->d_inode->i_flock)

By moving initialization of 'struct inode' pointer before the pos/count
sanity tests, we allow the compiler and processor to perform two loads by
anticipation, reducing stall, without prefetch() hints.  Even x86 arch has
enough registers to not use temporary variables and not increase text size.

I validated this patch running a bench and studied oprofile changes, and
absolute perf of the test program.

Results of my epoll_pipe_bench (source available on request) on a Pentium-M
1.6 GHz machine

Before :
# ./epoll_pipe_bench -l 30 -t 20
Avg: 436089 evts/sec read_count=8843037 write_count=8843040 21.218390 samples
per call
(best value out of 10 runs)

After :
# ./epoll_pipe_bench -l 30 -t 20
Avg: 470980 evts/sec read_count=9549871 write_count=9549894 21.216694 samples
per call
(best value out of 10 runs)

oprofile CPU_CLK_UNHALTED events gave a reduction from 5.3401 % to 2.5851 %
for the rw_verify_area() function.

Subject: [PATCH 1773/1971] [PATCH] Char: specialix, isr have 2 params

specialix, isr have 2 params

pt_regs are no longer the third parameter of isr, call sx_interrupt without
it.

Date: Mon, 12 Feb 2007 00:52:31 -0800
Subject: [PATCH 1774/1971] [PATCH] Char: timers cleanup

- Use timer macros to set function and data members and to modify
  expiration time.
- Use DEFINE_TIMER for global timers and do not init them at run-time in
  these cases.
- del_timer_sync is common in most cases -- we want to wait for timer
  function if it's still running.

Subject: [PATCH 1775/1971] [PATCH] drivers/telephony/ixj: Convert to generic
 boolean

Convert:
BOOL  -> bool
FALSE -> false
TRUE  -> true

Change a variable ('mContinue') to boolean from char, since it is used
as boolean.

      To get the device working, you have to load the proper kernel module. You
      can do this using
          modprobe modulename
-     where modulename is usb_gigaset (M105) or bas_gigaset (direct USB
-     connection to the base).
+     where modulename is ser_gigaset (M101), usb_gigaset (M105), or
+     bas_gigaset (direct USB connection to the base).
+
+     The module ser_gigaset provides a serial line discipline N_GIGASET_M101
+     which drives the device through the regular serial line driver. To use it,
+     run the Gigaset M101 daemon "gigasetm101d" (also available from
+     http://sourceforge.net/projects/gigaset307x/) with the device file of the
+     RS232 port to the M101 as an argument, for example:
+	 gigasetm101d /dev/ttyS1
+     This will open the device file, set its line discipline to N_GIGASET_M101,
+     and then sleep in the background, keeping the device open so that the
+     line discipline remains active. To deactivate it, kill the daemon, for
+     example with
+	 killall gigasetm101d
+     before disconnecting the device.
 
 2.2. Device nodes for user space programs
      ------------------------------------
      The device can be accessed from user space (eg. by the user space tools
      mentioned in 1.2.) through the device nodes:
 
+     - /dev/ttyGS0 for M101 (RS232 data boxes)
      - /dev/ttyGU0 for M105 (USB data boxes)
      - /dev/ttyGB0 for the base driver (direct USB connection)

      You can also use /sys/class/tty/ttyGxy/cidmode for changing the CID mode
      setting (ttyGxy is ttyGU0 or ttyGB0).
 
+2.6. M105 Undocumented USB Requests
+     ------------------------------
+
+     The Gigaset M105 USB data box understands a couple of useful, but
+     undocumented USB commands. These requests are not used in normal
+     operation (for wireless access to the base), but are needed for access
+     to the M105's own configuration mode (registration to the base, baudrate
+     and line format settings, device status queries) via the gigacontr
+     utility. Their use is disabled in the driver by default for safety
+     reasons but can be enabled by setting the kernel configuration option
+     "Support for undocumented USB requests" (GIGASET_UNDOCREQ) to "Y" and
+     recompiling.

Subject: [PATCH 1779/1971] [PATCH] SPI controller driver for OMAP Microwire

This adds a SPI driver for the Microwire controller on OMAP1 chips.  This
driver has been used in the Linux-OMAP tree for some time now, including
with some of those displays using standardized 9-bit commands followed by
data with 8-bit words.

Microwire only supports half duplex transfers, but that's all that most SPI
protocols need.  When full duplex, or higher speeds, are needed there are
several other controllers that can be used on OMAP.

From 69c202afa8ad6d6c1c673d8f9d47b43a0a3604e5 Mon Sep 17 00:00:00 2001
From: Andrea Paterniani <a.paterniani@swapp-eng.it>
Date: Mon, 12 Feb 2007 00:52:39 -0800
Subject: [PATCH 1780/1971] [PATCH] SPI: Freescale iMX SPI controller driver
 (BIS+)

Add the SPI controller driver for Freescale i.MX(S/L/1).
Main features summary:

 > Per chip setup via board specific code and/or protocol driver.
 > Per transfer setup.
 > PIO transfers.
 > DMA transfers.
 > Managing of NULL tx / rx buffer for rd only / wr only transfers.

This patch replace patch-2.6.20-rc4-spi_imx with the following changes:
 > Few cosmetic changes.
 > Function map_dma_buffers now return 0 for success and -1 for failure.
 > Solved a bug inside spi_imx_probe function (wrong error path).
 > Solved a bug inside setup function (bad undo setup for max_speed_hz).
 > For read-only transfers, always write zero bytes.

This is almost the same as the 'BIS' version sent by Andrea, except for
updating the 'DUMMY' byte so that read-only transfers shift out zeroes.
That part of the API changed recently, since some half duplex peripheral
chips require that semantic.

Subject: [PATCH 1784/1971] [PATCH] spi_bitbang(): use overridable
 setup_transfer() method

A small bug-fix for spi_bitbang: it must always call the setup_transfer
function via the overridable pointer, not assume that its
spi_bitbang_setup_transfer is sufficient.  Otherwise, if all options in the
transfers are default (0), the overrided function will never be called.

Granted, the function replacing it must call spi_bitbang_setup_transfer,
but it might also have other important things to do, even if the second
argument (the spi_transfer) is NULL.  Tested together with the other
patches on the spi_crisv32_sser and spi_crisv32_gpio drivers (not yet in
the kernel, will IIUC be submitted as part of the usual
arch-maintainer-pushes).

Subject: [PATCH 1785/1971] [PATCH] SPI cleanup() method param becomes
 non-const

I'd like to assign NULL to kfree()d members of a structure.  I can't do
that without ugly casting (see the PXA patch) when the structure pointed to
is const-qualified.  I don't really see a reason why the cleanup method
isn't allowed to alter the object it should clean up.  :-)

No, I didn't test the PXA patch, but I verified that the NULL-assignment
doesn't stop me from doing rmmod/insmodding my own spi_bitbang-based
driver.

Subject: [PATCH 1786/1971] [PATCH] SPI doc clarifications

This clarifies some aspects of the SPI programming interface, based on
feedback from Hans-Peter Nilsson.  The in-memory representation of words is
right-aligned, so for example a twelve bit word is stored using sixteen bits
with four undefined bits in the MSB.  And controller drivers must reject
protocol tweaking modes they do not support.

Subject: [PATCH 1787/1971] [PATCH] RTC gets sysfs wakealarm attribute

This adds a new "wakealarm" sysfs attribute to RTC class devices which support
alarm operations and are wakeup-capable:

 - It reads as either empty, or the scheduled alarm time as seconds
   since the POSIX epoch.  (That time may already have passed, since
   nothing currently enforces one-shot alarm semantics.)

 - It can be written with an alarm time in the future, again seconds
   since the POSIX epoch, which enables the alarm.

 - It can be written with an alarm time not in the future (such as 0,
   the start of the POSIX epoch) to disable the alarm.

Usage examples (some need GNU date) after "cd /sys/class/rtc/rtcN":

    alarm after 10 minutes:
	# echo $(( $(cat since_epoch) + 10 * 60 )) > wakealarm
    alarm tuesday evening 10pm:
	# date -d '10pm tuesday' "+%s" > wakealarm
    disable alarm:
    	# echo 0 > wakealarm

This resembles the /proc/acpi/alarm file in that nothing happens when the
alarm triggers ...  except possibly waking the system from sleep.  It's also
like that in a nasty way: not much can be done to prevent one task from
clobbering another task's alarm settings.

It differs from that file in that there's no in-kernel date parser.

Note that a few RTCs ignore rtc_wkalrm.enabled when setting alarms, or aren't
set up correctly, so they won't yet behave with this attribute.

Subject: [PATCH 1788/1971] [PATCH] SPI eeprom driver

This is adds a simple SPI EEPROM driver, providing access to the EEPROM
through sysfs much like the I2C "eeprom" driver ...  except this driver
supports write access, and multiple EEPROM sizes.

From: "Tuppa, Walter" <walter.tuppa@siemens.com>

Since I have EEPROMs on SPI with different address sizing, I made some
changes to your at25.c to support them.  Works perfectly.  (Also includes a
small bugfix for the "what size address" test.)

From 939b00df0306bc4b5cd25c3c3c78e89b91e72fc8 Mon Sep 17 00:00:00 2001
From: Andries Brouwer <aeb@cwi.nl>
Date: Mon, 12 Feb 2007 00:52:49 -0800
Subject: [PATCH 1789/1971] [PATCH] Minix V3 support

This morning I needed to read a Minix V3 filesystem, but unfortunately my
2.6.19 did not support that, and neither did the downloaded 2.6.20rc4.

Fortunately, google told me that Daniel Aragones had already done the work,
patch found at http://www.terra.es/personal2/danarag/

Unfortunaly, looking at the patch was painful to my eyes, so I polished it
a bit before applying.  The resulting kernel boots, and reads the
filesystem it needed to read.

Subject: [PATCH 1790/1971] [PATCH] tty: make __proc_set_tty static

The aim of this patch set is to start wrapping up the struct pid conversions.
As such this patchset culminates with the removal of kill_pg, kill_pg_info,
__kill_pg_info, do_each_task_pid, and while_each_task_pid.

kill_proc, daemonize, and kernel_thread are still in my sights but there is
still work to get to them.

The first three are basic cleanups around disassociate_ctty, while working on
converting it I found several issues.  tty_old_pgrp can be a tricky concept to
wrap your head around.

 1 tty: Make __proc_set_tty static.
 2 tty: Clarify disassociate_ctty
 3 tty: Fix the locking for signal->session in disassociate_ctty

These just stop using the old helper functions.

 4 signal: Use kill_pgrp not kill_pg in the sunos compatibility code.
 5 signal: Rewrite kill_something_info so it uses newer helpers.

Then the grind to convert the tty layer and all of it's helper functions to
struct pid.

 6 pid: Make session_of_pgrp use struct pid instead of pid_t.
 7 pid: Use struct pid for talking about process groups in exit.c
 8 pid: Replace is_orphaned_pgrp with is_current_pgrp_orphaned
 9 tty: Update the tty layer to work with struct pid.

A final helper function update.

10 pid: Replace do/while_each_task_pid with do/while_each_pid_task

And the removal of the functions that are now unused.
11 pid: Remove now unused do_each_task_pid and while_each_task_pid
12 pid: Remove the now unused kill_pg kill_pg_info and __kill_pg_info

All of these should be fairly simple and to the point.

This patch:

Currently all users of __proc_set_tty are in tty_io.c so make the function
static.

Subject: [PATCH 1791/1971] [PATCH] tty: clarify disassociate_ctty

The code to look at tty_old_pgrp and send SIGHUP and SIGCONT when it is
present only executes when disassociate_ctty is called from do_exit.  Make
this clear by adding an explict on_exit check, and explicitly setting
tty_old_pgrp to 0.

In addition fix the locking by reading tty_old_pgrp under the siglock.

Subject: [PATCH 1792/1971] [PATCH] tty: fix the locking for signal->session in
 disassociate_ctty

commit 24ec839c431eb79bb8f6abc00c4e1eb3b8c4d517 while fixing the locking for
signal->tty got the locking wrong for signal->session.  This places our
accesses of signal->session back under the tasklist_lock where they belong.

Subject: [PATCH 1793/1971] [PATCH] signal: use kill_pgrp not kill_pg in the
 sunos compatibility code

I am slowly moving to a model where all process killing is struct pid based
instead of pid_t based.  The sunos compatibility code is one of the last users
of the old pid_t based kill_pg in the kernel.  By being complete I allow for
the future removal of kill_pg from the kernel, which will ensure I don't miss
something.

Subject: [PATCH 1795/1971] [PATCH] pid: make session_of_pgrp use struct pid
 instead of pid_t

To properly implement a pid namespace I need to deal exclusively in terms of
struct pid, because pid_t values become ambiguous.

To this end session_of_pgrp is transformed to take and return a struct pid
pointer.  To avoid the need to worry about reference counting I now require my
caller to hold the appropriate locks.  Leaving callers repsonsible for
increasing the reference count if they need access to the result outside of
the locks.

Since session_of_pgrp currently only has one caller and that caller simply
uses only test the result for equality with another process group, the locking
change means I don't actually have to acquire the tasklist_lock at all.

tiocspgrp is also modified to take and release the lock.  The logic there is a
little more complicated but nothing I won't need when I convert pgrp of a tty
to a struct pid pointer.

Subject: [PATCH 1797/1971] [PATCH] pid: replace is_orphaned_pgrp with
 is_current_pgrp_orphaned

Every call to is_orphaned_pgrp passed in process_group(current) which is racy
with respect to another thread changing our process group.  It didn't bite us
because we were dealing with integers and the worse we would get would be a
stale answer.

In switching the checks to use struct pid to be a little more efficient and
prepare the way for pid namespaces this race became apparent.

So I simplified the calls to the more specialized is_current_pgrp_orphaned so
I didn't have to worry about making logic changes to avoid the race.

From ab521dc0f8e117fd808d3e425216864d60390500 Mon Sep 17 00:00:00 2001
From: "Eric W. Biederman" <ebiederm@xmission.com>
Date: Mon, 12 Feb 2007 00:53:00 -0800
Subject: [PATCH 1798/1971] [PATCH] tty: update the tty layer to work with
 struct pid

Of kernel subsystems that work with pids the tty layer is probably the largest
consumer.  But it has the nice virtue that the assiation with a session only
lasts until the session leader exits.  Which means that no reference counting
is required.  So using struct pid winds up being a simple optimization to
avoid hash table lookups.

In the long term the use of pid_nr also ensures that when we have multiple pid
spaces mixed everything will work correctly.

Subject: [PATCH 1799/1971] [PATCH] pid: replace do/while_each_task_pid with
 do/while_each_pid_task

There isn't any real advantage to this change except that it allows the old
functions to be removed.  Which is easier on maintenance and puts the code in
a more uniform style.

Subject: [PATCH 1803/1971] [PATCH] EDAC: e752x byte access fix

The reading of the DRA registers should be a byte at a time (one register at a
time) instead of 4 bytes at a time (four registers).  Reading a dword at a
time retrieves erroneous information from all but the first register.  A
change was made to read in each register in a loop prior to using the data in
those registers.

Subject: [PATCH 1805/1971] [PATCH] EDAC: Add memory scrubbing controls API to
 core

This is an attempt of providing an interface for memory scrubbing control in
EDAC.

This patch modifies the EDAC Core to provide the Interface for memory
controller modules to implment.

The following things are still outstanding:

 - K8 is the first implemenation,

   The patch provide a method of configuring the K8 hardware memory scrubber
   via the 'mcX' sysfs directory.  There should be some fallback to a generic
   scrubber implemented in software if the hardware does not support
   scrubbing.

   Or .. the scrubbing sysfs entry should not be visible at all.

 - Only works with SDRAM, not cache,

   The K8 can scrub cache and l2cache also - but I think this is not so
   useful as the cache is busy all the time (one hopes).

   One would also expect that cache scrubbing requires hardware support.

 - Error Handling,

   I would like that errors are returned to the user in "terms of file
   system".

 - Presentation,

   I chose Bandwidth in Bytes/Second as a representation of the scrubbing
   rate for the following reasons:

   I like that the sysfs entries are sort-of textual, related to something
   that makes sense instead of magical values that must be looked up.

   "My People" wants "% main memory scrubbed per hour" others prefer "%
   memory bandwidth used" as representation, "bandwith used" makes it easy to
   calculate both versions in one-liner scripts.

   If one later wants to scrub cache, the scaling becomes wierd for K8
   changing from "blocks of 64 byte memory" to "blocks of 64 cache lines" to
   "blocks of 64 bit".  Using "bandwidth used" makes sense in all three cases,
   (I.M.O.  anyway ;-).

 - Discovery,

   There is no way to discover the possible settings and what they do
   without reading the code and the documentation.

   *I* do not know how to make that work in a practical way.

 - Bugs(??),

   other tools can set invalid values in the memory scrub control register,
   those will read back as '-1', requiring the user to reset the scrub rate.
   This is how *I* think it should be.

 - Afflicting other areas of code,

   I made changes to edac_mc.c and edac_mc.h which will show up globally -
   this is not nice, it would be better that the memory scrubbing fuctionality
   and interface could be entirely contained within the memory controller it
   applies to.

Frithiof Jensen

edac_mc.c and its .h file is a CORE helper module for EDAC
driver modules. This provides the abstraction for device specific
drivers. It is fine to modify this CORE to provide help for
new features of the the drivers

Subject: [PATCH 1807/1971] [PATCH] GPIO core

This defines a simple and minimalist programming interface for GPIO APIs:

  - Documentation/gpio.txt ... describes things (read it)

  - include/asm-arm/gpio.h ... defines the ARM hook, which just punts
    to <asm/arch/gpio.h> for any implementation

  - include/asm-generic/gpio.h ... implement "can sleep" variants as calling
    the normal ones, for systems that don't handle i2c expanders.

The immediate need for such a cross-architecture API convention is to support
drivers that work the same on AT91 ARM and AVR32 AP7000 chips, which embed many
of the same controllers but have different CPUs.  However, several other users
have been reported, including a driver for a hardware watchdog chip and some
handhelds.org multi-CPU button drivers.

+GPIO Interfaces
+
+This provides an overview of GPIO access conventions on Linux.
+
+
+What is a GPIO?
+===============
+A "General Purpose Input/Output" (GPIO) is a flexible software-controlled
+digital signal.  They are provided from many kinds of chip, and are familiar
+to Linux developers working with embedded and custom hardware.  Each GPIO
+represents a bit connected to a particular pin, or "ball" on Ball Grid Array
+(BGA) packages.  Board schematics show which external hardware connects to
+which GPIOs.  Drivers can be written generically, so that board setup code
+passes such pin configuration data to drivers.
+
+System-on-Chip (SOC) processors heavily rely on GPIOs.  In some cases, every
+non-dedicated pin can be configured as a GPIO; and most chips have at least
+several dozen of them.  Programmable logic devices (like FPGAs) can easily
+provide GPIOs; multifunction chips like power managers, and audio codecs
+often have a few such pins to help with pin scarcity on SOCs; and there are
+also "GPIO Expander" chips that connect using the I2C or SPI serial busses.
+Most PC southbridges have a few dozen GPIO-capable pins (with only the BIOS
+firmware knowing how they're used).
+
+The exact capabilities of GPIOs vary between systems.  Common options:
+
+  - Output values are writable (high=1, low=0).  Some chips also have
+    options about how that value is driven, so that for example only one
+    value might be driven ... supporting "wire-OR" and similar schemes
+    for the other value.
+
+  - Input values are likewise readable (1, 0).  Some chips support readback
+    of pins configured as "output", which is very useful in such "wire-OR"
+    cases (to support bidirectional signaling).  GPIO controllers may have
+    input de-glitch logic, sometimes with software controls.
+
+  - Inputs can often be used as IRQ signals, often edge triggered but
+    sometimes level triggered.  Such IRQs may be configurable as system
+    wakeup events, to wake the system from a low power state.
+
+  - Usually a GPIO will be configurable as either input or output, as needed
+    by different product boards; single direction ones exist too.
+
+  - Most GPIOs can be accessed while holding spinlocks, but those accessed
+    through a serial bus normally can't.  Some systems support both types.
+
+On a given board each GPIO is used for one specific purpose like monitoring
+MMC/SD card insertion/removal, detecting card writeprotect status, driving
+a LED, configuring a transceiver, bitbanging a serial bus, poking a hardware
+watchdog, sensing a switch, and so on.
+
+
+GPIO conventions
+================
+Note that this is called a "convention" because you don't need to do it this
+way, and it's no crime if you don't.  There **are** cases where portability
+is not the main issue; GPIOs are often used for the kind of board-specific
+glue logic that may even change between board revisions, and can't ever be
+used on a board that's wired differently.  Only least-common-denominator
+functionality can be very portable.  Other features are platform-specific,
+and that can be critical for glue logic.
+
+Plus, this doesn't define an implementation framework, just an interface.
+One platform might implement it as simple inline functions accessing chip
+registers; another might implement it by delegating through abstractions
+used for several very different kinds of GPIO controller.
+
+That said, if the convention is supported on their platform, drivers should
+use it when possible:
+
+	#include <asm/gpio.h>
+
+If you stick to this convention then it'll be easier for other developers to
+see what your code is doing, and help maintain it.
+
+
+Identifying GPIOs
+-----------------
+GPIOs are identified by unsigned integers in the range 0..MAX_INT.  That
+reserves "negative" numbers for other purposes like marking signals as
+"not available on this board", or indicating faults.
+
+Platforms define how they use those integers, and usually #define symbols
+for the GPIO lines so that board-specific setup code directly corresponds
+to the relevant schematics.  In contrast, drivers should only use GPIO
+numbers passed to them from that setup code, using platform_data to hold
+board-specific pin configuration data (along with other board specific
+data they need).  That avoids portability problems.
+
+So for example one platform uses numbers 32-159 for GPIOs; while another
+uses numbers 0..63 with one set of GPIO controllers, 64-79 with another
+type of GPIO controller, and on one particular board 80-95 with an FPGA.
+The numbers need not be contiguous; either of those platforms could also
+use numbers 2000-2063 to identify GPIOs in a bank of I2C GPIO expanders.
+
+Whether a platform supports multiple GPIO controllers is currently a
+platform-specific implementation issue.
+
+
+Using GPIOs
+-----------
+One of the first things to do with a GPIO, often in board setup code when
+setting up a platform_device using the GPIO, is mark its direction:
+
+	/* set as input or output, returning 0 or negative errno */
+	int gpio_direction_input(unsigned gpio);
+	int gpio_direction_output(unsigned gpio);
+
+The return value is zero for success, else a negative errno.  It should
+be checked, since the get/set calls don't have error returns and since
+misconfiguration is possible.  (These calls could sleep.)
+
+Setting the direction can fail if the GPIO number is invalid, or when
+that particular GPIO can't be used in that mode.  It's generally a bad
+idea to rely on boot firmware to have set the direction correctly, since
+it probably wasn't validated to do more than boot Linux.  (Similarly,
+that board setup code probably needs to multiplex that pin as a GPIO,
+and configure pullups/pulldowns appropriately.)
+
+
+Spinlock-Safe GPIO access
+-------------------------
+Most GPIO controllers can be accessed with memory read/write instructions.
+That doesn't need to sleep, and can safely be done from inside IRQ handlers.
+
+Use these calls to access such GPIOs:
+
+	/* GPIO INPUT:  return zero or nonzero */
+	int gpio_get_value(unsigned gpio);
+
+	/* GPIO OUTPUT */
+	void gpio_set_value(unsigned gpio, int value);
+
+The values are boolean, zero for low, nonzero for high.  When reading the
+value of an output pin, the value returned should be what's seen on the
+pin ... that won't always match the specified output value, because of
+issues including wire-OR and output latencies.
+
+The get/set calls have no error returns because "invalid GPIO" should have
+been reported earlier in gpio_set_direction().  However, note that not all
+platforms can read the value of output pins; those that can't should always
+return zero.  Also, these calls will be ignored for GPIOs that can't safely
+be accessed wihtout sleeping (see below).
+
+Platform-specific implementations are encouraged to optimise the two
+calls to access the GPIO value in cases where the GPIO number (and for
+output, value) are constant.  It's normal for them to need only a couple
+of instructions in such cases (reading or writing a hardware register),
+and not to need spinlocks.  Such optimized calls can make bitbanging
+applications a lot more efficient (in both space and time) than spending
+dozens of instructions on subroutine calls.
+
+
+GPIO access that may sleep
+--------------------------
+Some GPIO controllers must be accessed using message based busses like I2C
+or SPI.  Commands to read or write those GPIO values require waiting to
+get to the head of a queue to transmit a command and get its response.
+This requires sleeping, which can't be done from inside IRQ handlers.
+
+Platforms that support this type of GPIO distinguish them from other GPIOs
+by returning nonzero from this call:
+
+	int gpio_cansleep(unsigned gpio);
+
+To access such GPIOs, a different set of accessors is defined:
+
+	/* GPIO INPUT:  return zero or nonzero, might sleep */
+	int gpio_get_value_cansleep(unsigned gpio);
+
+	/* GPIO OUTPUT, might sleep */
+	void gpio_set_value_cansleep(unsigned gpio, int value);
+
+Other than the fact that these calls might sleep, and will not be ignored
+for GPIOs that can't be accessed from IRQ handlers, these calls act the
+same as the spinlock-safe calls.
+
+
+Claiming and Releasing GPIOs (OPTIONAL)
+---------------------------------------
+To help catch system configuration errors, two calls are defined.
+However, many platforms don't currently support this mechanism.
+
+	/* request GPIO, returning 0 or negative errno.
+	 * non-null labels may be useful for diagnostics.
+	 */
+	int gpio_request(unsigned gpio, const char *label);
+
+	/* release previously-claimed GPIO */
+	void gpio_free(unsigned gpio);
+
+Passing invalid GPIO numbers to gpio_request() will fail, as will requesting
+GPIOs that have already been claimed with that call.  The return value of
+gpio_request() must be checked.  (These calls could sleep.)
+
+These calls serve two basic purposes.  One is marking the signals which
+are actually in use as GPIOs, for better diagnostics; systems may have
+several hundred potential GPIOs, but often only a dozen are used on any
+given board.  Another is to catch conflicts between drivers, reporting
+errors when drivers wrongly think they have exclusive use of that signal.
+
+These two calls are optional because not not all current Linux platforms
+offer such functionality in their GPIO support; a valid implementation
+could return success for all gpio_request() calls.  Unlike the other calls,
+the state they represent doesn't normally match anything from a hardware
+register; it's just a software bitmap which clearly is not necessary for
+correct operation of hardware or (bug free) drivers.
+
+Note that requesting a GPIO does NOT cause it to be configured in any
+way; it just marks that GPIO as in use.  Separate code must handle any
+pin setup (e.g. controlling which pin the GPIO uses, pullup/pulldown).
+
+
+GPIOs mapped to IRQs
+--------------------
+GPIO numbers are unsigned integers; so are IRQ numbers.  These make up
+two logically distinct namespaces (GPIO 0 need not use IRQ 0).  You can
+map between them using calls like:
+
+	/* map GPIO numbers to IRQ numbers */
+	int gpio_to_irq(unsigned gpio);
+
+	/* map IRQ numbers to GPIO numbers */
+	int irq_to_gpio(unsigned irq);
+
+Those return either the corresponding number in the other namespace, or
+else a negative errno code if the mapping can't be done.  (For example,
+some GPIOs can't used as IRQs.)  It is an unchecked error to use a GPIO
+number that hasn't been marked as an input using gpio_set_direction(), or
+to use an IRQ number that didn't originally come from gpio_to_irq().
+
+These two mapping calls are expected to cost on the order of a single
+addition or subtraction.  They're not allowed to sleep.
+
+Non-error values returned from gpio_to_irq() can be passed to request_irq()
+or free_irq().  They will often be stored into IRQ resources for platform
+devices, by the board-specific initialization code.  Note that IRQ trigger
+options are part of the IRQ interface, e.g. IRQF_TRIGGER_FALLING, as are
+system wakeup capabilities.
+
+Non-error values returned from irq_to_gpio() would most commonly be used
+with gpio_get_value().
+
+
+
+What do these conventions omit?
+===============================
+One of the biggest things these conventions omit is pin multiplexing, since
+this is highly chip-specific and nonportable.  One platform might not need
+explicit multiplexing; another might have just two options for use of any
+given pin; another might have eight options per pin; another might be able
+to route a given GPIO to any one of several pins.  (Yes, those examples all
+come from systems that run Linux today.)
+
+Related to multiplexing is configuration and enabling of the pullups or
+pulldowns integrated on some platforms.  Not all platforms support them,
+or support them in the same way; and any given board might use external
+pullups (or pulldowns) so that the on-chip ones should not be used.
+
+There are other system-specific mechanisms that are not specified here,
+like the aforementioned options for input de-glitching and wire-OR output.
+Hardware may support reading or writing GPIOs in gangs, but that's usually
+configuration dependednt:  for GPIOs sharing the same bank.  (GPIOs are
+commonly grouped in banks of 16 or 32, with a given SOC having several such
+banks.)  Code relying on such mechanisms will necessarily be nonportable.
+
+Dynamic definition of GPIOs is not currently supported; for example, as
+a side effect of configuring an add-on board with some GPIO expanders.
+
+These calls are purely for kernel space, but a userspace API could be built
+on top of it.

Subject: [PATCH 1809/1971] [PATCH] AT91 GPIO wrappers

This is a first cut at making the AT91 code use the generic GPIO calls.

Note that the original AT91 GPIO calls merged the "mux pin as GPIO" and "set
GPIO direction" functionality into one API call, contrary to what's specified
as a cross-platform portable model.  So this involved a few non-inlinable
functions.

Date: Mon, 12 Feb 2007 00:53:17 -0800
Subject: [PATCH 1814/1971] [PATCH] drivers/isdn/hisax/: proper prototypes

- add functions prototypes for some global functions to header files

- remove unneeded "extern"s from some function prototypes

You might note that this patch results in a new warning - that's due to the
fact that with a proper prototype gcc is able to discover a broken
work_struct conversion.

From: Adrian Bunk <bunk@stusta.de>

Subject: [PATCH 1815/1971] [PATCH] drivers/isdn/sc/: proper prototypes

Add proper prototypes in a header file for global code under
drivers/isdn/sc/.

Since the GNU C compiler is now able do tell us that caller and callee
disagreed about the number of arguments of setup_buffers(), this patch
also fixes this bug.

From 053b47ff249b9e0a634dae807f81465205e7c228 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1824/1971] [PATCH] Workaround CAPI subsystem locking issue

I think the following patch should go into the kernel, until the ISDN/CAPI
guys create the real fix for this issue.

The issue is a concurrency issue with some internal CAPI data structure
which can crash the kernel.

On my FritzCard DSL with the AVM driver it crashes about once a day without
this workaround patch.  With this workaround patch it's rock-stable (at
least on UP, but I don't see why this shouldn't work on SMP as well.  But
maybe I'm missing something.)

This workaround is kind of a sledgehammer which inserts a global lock to
wrap around all the critical sections.  Of course, this is a scalability
issue, if you have many ISDN/CAPI cards.  But it prevents a crash.  So I
vote for this fix to get merged, until people come up with a better
solution.  Better have a stable kernel that's less scalable, than a
crashing and useless kernel.

This bug is in the kernel since 2.6.15 (at least).

Subject: [PATCH 1826/1971] [PATCH] knfsd: SUNRPC: update internal API:
 separate pmap register and temp sockets

Currently in the RPC server, registering with the local portmapper and
creating "permanent" sockets are tied together.  Expand the internal APIs to
allow these two socket characteristics to be separately specified.

This will be externalized in the next patch.

Subject: [PATCH 1827/1971] [PATCH] knfsd: SUNRPC: allow creating an RPC
 service without registering with portmapper

Sometimes we need to create an RPC service but not register it with the local
portmapper.  NFSv4 delegation callback, for example.

Change the svc_makesock() API to allow optionally creating temporary or
permanent sockets, optionally registering with the local portmapper, and make
it return the ephemeral port of the new socket.

Subject: [PATCH 1828/1971] [PATCH] knfsd: SUNRPC: aplit svc_sock_enqueue out
 of svc_setup_socket

Rather than calling svc_sock_enqueue at the end of svc_setup_socket, we now
call it (via svc_sock_recieved) after calling svc_setup_socket at each call
site.

We do this because a subsequent patch will insert some code between the two
calls at one call site.

Subject: [PATCH 1831/1971] [PATCH] knfsd: SUNRPC: Add a function to format the
 address in an svc_rqst for printing

There are loads of places where the RPC server assumes that the rq_addr fields
contains an IPv4 address.  Top among these are error and debugging messages
that display the server's IP address.

Let's refactor the address printing into a separate function that's smart
enough to figure out the difference between IPv4 and IPv6 addresses.

Subject: [PATCH 1833/1971] [PATCH] knfsd: SUNRPC: Provide room in svc_rqst for
 larger addresses

Expand the rq_addr field to allow it to contain larger addresses.

Specifically, we replace a 'sockaddr_in' with a 'sockaddr_storage', then
everywhere the 'sockaddr_in' was referenced, we use instead an accessor
function (svc_addr_in) which safely casts the _storage to _in.

Subject: [PATCH 1836/1971] [PATCH] knfsd: SUNRPC: add a "generic" function to
 see if the peer uses a secure port

The only reason svcsock.c looks at a sockaddr's port is to check whether the
remote peer is connecting from a privileged port.  Refactor this check to hide
processing that is specific to address format.

Subject: [PATCH 1841/1971] [PATCH] eCryptfs: Public key transport mechanism

This is the transport code for public key functionality in eCryptfs.  It
manages encryption/decryption request queues with a transport mechanism.
Currently, netlink is the only implemented transport.

Each inode has a unique File Encryption Key (FEK).  Under passphrase, a File
Encryption Key Encryption Key (FEKEK) is generated from a salt/passphrase
combo on mount.  This FEKEK encrypts each FEK and writes it into the header of
each file using the packet format specified in RFC 2440.  This is all
symmetric key encryption, so it can all be done via the kernel crypto API.

These new patches introduce public key encryption of the FEK.  There is no
asymmetric key encryption support in the kernel crypto API, so eCryptfs pushes
the FEK encryption and decryption out to a userspace daemon.  After
considering our requirements and determining the complexity of using various
transport mechanisms, we settled on netlink for this communication.

eCryptfs stores authentication tokens into the kernel keyring.  These tokens
correlate with individual keys.  For passphrase mode of operation, the
authentication token contains the symmetric FEKEK.  For public key, the
authentication token contains a PKI type and an opaque data blob managed by
individual PKI modules in userspace.

Each user who opens a file under an eCryptfs partition mounted in public key
mode must be running a daemon.  That daemon has the user's credentials and has
access to all of the keys to which the user should have access.  The daemon,
when started, initializes the pluggable PKI modules available on the system
and registers itself with the eCryptfs kernel module.  Userspace utilities
register public key authentication tokens into the user session keyring.
These authentication tokens correlate key signatures with PKI modules and PKI
blobs.  The PKI blobs contain PKI-specific information necessary for the PKI
module to carry out asymmetric key encryption and decryption.

When the eCryptfs module parses the header of an existing file and finds a Tag
1 (Public Key) packet (see RFC 2440), it reads in the public key identifier
(signature).  The asymmetrically encrypted FEK is in the Tag 1 packet;
eCryptfs puts together a decrypt request packet containing the signature and
the encrypted FEK, then it passes it to the daemon registered for the
current->euid via a netlink unicast to the PID of the daemon, which was
registered at the time the daemon was started by the user.

The daemon actually just makes calls to libecryptfs, which implements request
packet parsing and manages PKI modules.  libecryptfs grabs the public key
authentication token for the given signature from the user session keyring.
This auth tok tells libecryptfs which PKI module should receive the request.
libecryptfs then makes a decrypt() call to the PKI module, and it passes along
the PKI block from the auth tok.  The PKI uses the blob to figure out how it
should decrypt the data passed to it; it performs the decryption and passes
the decrypted data back to libecryptfs.  libecryptfs then puts together a
reply packet with the decrypted FEK and passes that back to the eCryptfs
module.

The eCryptfs module manages these request callouts to userspace code via
message context structs.  The module maintains an array of message context
structs and places the elements of the array on two lists: a free and an
allocated list.  When eCryptfs wants to make a request, it moves a msg ctx
from the free list to the allocated list, sets its state to pending, and fires
off the message to the user's registered daemon.

When eCryptfs receives a netlink message (via the callback), it correlates the
msg ctx struct in the alloc list with the data in the message itself.  The
msg->index contains the offset of the array of msg ctx structs.  It verifies
that the registered daemon PID is the same as the PID of the process that sent
the message.  It also validates a sequence number between the received packet
and the msg ctx.  Then, it copies the contents of the message (the reply
packet) into the msg ctx struct, sets the state in the msg ctx to done, and
wakes up the process that was sleeping while waiting for the reply.

The sleeping process was whatever was performing the sys_open().  This process
originally called ecryptfs_send_message(); it is now in
ecryptfs_wait_for_response().  When it wakes up and sees that the msg ctx
state was set to done, it returns a pointer to the message contents (the reply
packet) and returns.  If all went well, this packet contains the decrypted
FEK, which is then copied into the crypt_stat struct, and life continues as
normal.

The case for creation of a new file is very similar, only instead of a decrypt
request, eCryptfs sends out an encrypt request.

> - We have a great clod of key mangement code in-kernel.  Why is that
>   not suitable (or growable) for public key management?

eCryptfs uses Howells' keyring to store persistent key data and PKI state
information.  It defers public key cryptographic transformations to userspace
code.  The userspace data manipulation request really is orthogonal to key
management in and of itself.  What eCryptfs basically needs is a secure way to
communicate with a particular daemon for a particular task doing a syscall,
based on the UID.  Nothing running under another UID should be able to access
that channel of communication.

> - Is it appropriate that new infrastructure for public key
> management be private to a particular fs?

The messaging.c file contains a lot of code that, perhaps, could be extracted
into a separate kernel service.  In essence, this would be a sort of
request/reply mechanism that would involve a userspace daemon.  I am not aware
of anything that does quite what eCryptfs does, so I was not aware of any
existing tools to do just what we wanted.

>   What happens if one of these daemons exits without sending a quit
>   message?

There is a stale uid<->pid association in the hash table for that user.  When
the user registers a new daemon, eCryptfs cleans up the old association and
generates a new one.  See ecryptfs_process_helo().

> - _why_ does it use netlink?

Netlink provides the transport mechanism that would minimize the complexity of
the implementation, given that we can have multiple daemons (one per user).  I
explored the possibility of using relayfs, but that would involve having to
introduce control channels and a protocol for creating and tearing down
channels for the daemons.  We do not have to worry about any of that with
netlink.

From dddfa461fc8951f9b5f951c13565b6cac678635a Mon Sep 17 00:00:00 2001
From: Michael Halcrow <mhalcrow@us.ibm.com>
Date: Mon, 12 Feb 2007 00:53:44 -0800
Subject: [PATCH 1842/1971] [PATCH] eCryptfs: Public key; packet management

Public key support code.  This reads and writes packets in the header that
contain public key encrypted file keys.  It calls the messaging code in the
previous patch to send and receive encryption and decryption request
packets from the userspace daemon.

From 17398957aa0a05ef62535060b41d103590dcc533 Mon Sep 17 00:00:00 2001
From: Michael Halcrow <mhalcrow@us.ibm.com>
Date: Mon, 12 Feb 2007 00:53:45 -0800
Subject: [PATCH 1843/1971] [PATCH] eCryptfs: xattr flags and mount options

This patch set introduces the ability to store cryptographic metadata into an
lower file extended attribute rather than the lower file header region.

This patch set implements two new mount options:

ecryptfs_xattr_metadata
 - When set, newly created files will have their cryptographic
   metadata stored in the extended attribute region of the file rather
   than the header.

   When storing the data in the file header, there is a minimum of 8KB
   reserved for the header information for each file, making each file at
   least 12KB in size.  This can take up a lot of extra disk space if the user
   creates a lot of small files.  By storing the data in the extended
   attribute, each file will only occupy at least of 4KB of space.

   As the eCryptfs metadata set becomes larger with new features such as
   multi-key associations, most popular filesystems will not be able to store
   all of the information in the xattr region in some cases due to space
   constraints.  However, the majority of users will only ever associate one
   key per file, so most users will be okay with storing their data in the
   xattr region.

   This option should be used with caution.  I want to emphasize that the
   xattr must be maintained under all circumstances, or the file will be
   rendered permanently unrecoverable.  The last thing I want is for a user to
   forget to set an xattr flag in a backup utility, only to later discover
   that their backups are worthless.

ecryptfs_encrypted_view
 - When set, this option causes eCryptfs to present applications a
   view of encrypted files as if the cryptographic metadata were
   stored in the file header, whether the metadata is actually stored
   in the header or in the extended attributes.

   No matter what eCryptfs winds up doing in the lower filesystem, I want
   to preserve a baseline format compatibility for the encrypted files.  As of
   right now, the metadata may be in the file header or in an xattr.  There is
   no reason why the metadata could not be put in a separate file in future
   versions.

   Without the compatibility mode, backup utilities would have to know to
   back up the metadata file along with the files.  The semantics of eCryptfs
   have always been that the lower files are self-contained units of encrypted
   data, and the only additional information required to decrypt any given
   eCryptfs file is the key.  That is what has always been emphasized about
   eCryptfs lower files, and that is what users expect.  Providing the
   encrypted view option will provide a way to userspace applications wherein
   they can always get to the same old familiar eCryptfs encrypted files,
   regardless of what eCryptfs winds up doing with the metadata behind the
   scenes.

This patch:

Add extended attribute support to version bit vector, flags to indicate when
xattr or encrypted view modes are enabled, and support for the new mount
options.

Subject: [PATCH 1844/1971] [PATCH] eCryptfs: Generalize metadata read/write

Generalize the metadata reading and writing mechanisms, with two targets for
now: metadata in file header and metadata in the user.ecryptfs xattr of the
lower file.

From e77a56ddceeec87575a13a60fc1a394af6a1f4bc Mon Sep 17 00:00:00 2001

Date: Mon, 12 Feb 2007 00:53:47 -0800
Subject: [PATCH 1845/1971] [PATCH] eCryptfs: Encrypted passthrough

Provide an option to provide a view of the encrypted files such that the
metadata is always in the header of the files, regardless of whether the
metadata is actually in the header or in the extended attribute.  This mode of
operation is useful for applications like incremental backup utilities that do
not preserve the extended attributes when directly accessing the lower files.

With this option enabled, the files under the eCryptfs mount point will be
read-only.

Subject: [PATCH 1846/1971] [PATCH] eCryptfs: convert f_op->write() to
 vfs_write()

sys_write() takes a local copy of f_pos and writes that back
into the struct file. It does this so that two concurrent write()
callers don't make a mess of f_pos, and of the file contents.

ecryptfs should be calling vfs_write().  That way we also get the fsnotify
notifications, which ecryptfs presently appears to have subverted.

Convert direct calls to f_op->write() into calls to vfs_write().

Subject: [PATCH 1850/1971] [PATCH] sched: avoid div in rebalance_tick

Avoid expensive integer divide 3 times per CPU per tick.

A userspace test of this loop went from 26ns, down to 19ns on a G5; and
from 123ns down to 28ns on a P3.

(Also avoid a variable bit shift, as suggested by Alan. The effect
of this wasn't noticable on the CPUs I tested with).

Subject: [PATCH 1851/1971] [PATCH] Dynamic kernel command-line: common

Current implementation stores a static command-line buffer allocated to
COMMAND_LINE_SIZE size.  Most architectures stores two copies of this buffer,
one for future reference and one for parameter parsing.

Current kernel command-line size for most architecture is much too small for
module parameters, video settings, initramfs paramters and much more.  The
problem is that setting COMMAND_LINE_SIZE to a grater value, allocates static
buffers.

In order to allow a greater command-line size, these buffers should be
dynamically allocated or marked as init disposable buffers, so unused memory
can be released.

This patch renames the static saved_command_line variable into
boot_command_line adding __initdata attribute, so that it can be disposed
after initialization.  This rename is required so applications that use
saved_command_line will not be affected by this change.

It reintroduces saved_command_line as dynamically allocated buffer to match
the data in boot_command_line.

It also mark secondary command-line buffer as __initdata, and copies it to
dynamically allocated static_command_line buffer components may hold reference
to it after initialization.

This patch is for linux-2.6.20-rc4-mm1 and is divided to target each
architecture.  I could not check this in any architecture so please forgive me
if I got it wrong.

The per-architecture modification is very simple, use boot_command_line in
place of saved_command_line.  The common code is the change into dynamic
command-line.

This patch:

1. Rename saved_command_line into boot_command_line, mark as init
   disposable.

2. Add dynamic allocated saved_command_line.

3. Add dynamic allocated static_command_line.

4. During startup copy: boot_command_line into saved_command_line.  arch
   command_line into static_command_line.

5. Parse static_command_line and not arch command_line, so arch
   command_line may be freed.

Current implementation allows the kernel to receive up to 255 characters from
the bootloader.  While the boot protocol allows greater buffers to be sent.

In current environment, the command-line is used in order to specify many
values, including suspend/resume, module arguments, splash, initramfs and
more.

255 characters are not enough anymore.

After edd issue was fixed, and dynammic kernel command-line patch was
accepted, we can extend the COMMAND_LINE_SIZE without runtime memory
requirements.

Subject: [PATCH 1881/1971] [PATCH] ufs2 write: mount as rw

These series of patches add UFS2 write-support.  UFS2 - is default file system
for recent versions of FreeBSD.

The main differences from UFS1 from write support point of view
are:
1)Not all inodes are allocated during formatation of disk.
2)All meta-data(pointer to data blocks) are 64bit(in UFS1 they
are 32bit).

So patch series consist of
1)make possible mount UFS2 in read-write mode
2)code to write ufs2 inodes and code to initialize inodes chunks.
3)work with 64bit meta-data

I made simple testing like create/deleting/writing/reading/truncating, also I
ran fsx-linux and untar and build kernel on UFS1 and UFS2, after that FreeBSD
fsck do not find any errors in fs.

This patch makes possible to mount ufs2 "rw", and updates UFS2 documentation:
remove note about bug(it fixed by reallocate blocks on the fly patch) and add
me in the list of people who want receive bug reports.

From 3313e29267414e4e3bf0d3de1caf9cb439b64aaf Mon Sep 17 00:00:00 2001
From: Evgeniy Dushistov <dushistov@mail.ru>
Date: Mon, 12 Feb 2007 00:54:31 -0800
Subject: [PATCH 1882/1971] [PATCH] ufs2 write: inodes write

This patch adds into write inode path function to write UFS2 inode, and
modifys allocate inode path to allocate and init additional inode chunks.

Also some cleanups:
- remove not used parameters in some functions
- remove i_gen field from ufs_inode_info structure,
there is i_generation in inode structure with same purposes.

From: Evgeniy Dushistov <dushistov@mail.ru>
Date: Mon, 12 Feb 2007 00:54:32 -0800
Subject: [PATCH 1883/1971] [PATCH] ufs2 write: block allocation update

Patch adds ability to work with 64bit metadata, this made by replacing work
with 32bit pointers by inline functions.

Subject: [PATCH 1886/1971] [PATCH] kvm: Fix gva_to_gpa()

gva_to_gpa() needs to be updated to the new walk_addr() calling convention,
otherwise it may oops under some circumstances.

Use the opportunity to remove all the code duplication in gva_to_gpa(), which
essentially repeats the calculations in walk_addr().

Subject: [PATCH 1888/1971] [PATCH] kvm: Fix mmu going crazy of guest sets
 cr0.wp == 0

The kvm mmu relies on cr0.wp being set even if the guest does not set it.  The
vmx code correctly forces cr0.wp at all times, the svm code does not, so it
can't boot solaris without this patch.

We report the value of cr8 to userspace on an exit.  Also let userspace change
cr8 when we re-enter the guest.  The lets 64-bit guest code maintain the tpr
correctly.

Thanks for Yaniv Kamay for the idea.

vcpu_load() can return NULL and it sometimes does in failure paths (for
example when the userspace ABI version is too old) - causing a preemption
count underflow in the ->vcpu_free() later on.  So check for NULL.

Subject: [PATCH 1894/1971] [PATCH] hotplug: Allow modules to use the cpu
 hotplug notifiers even if !CONFIG_HOTPLUG_CPU

The following patchset allows a host with running virtual machines to be
suspended and, on at least a subset of the machines tested, resumed.  Note
that this is orthogonal to suspending and resuming an individual guest to a
file.

A side effect of implementing suspend/resume is that cpu hotplug is now
supported.  This should please the owners of big iron.

This patch:

KVM wants the cpu hotplug notifications, both for cpu hotplug itself, but more
commonly for host suspend/resume.

In order to avoid extensive #ifdefs, provide stubs when CONFIG_CPU_HOTPLUG is
not defined.

In all, we have four cases:

- UP: register and unregister stubbed out
- SMP+hotplug: full register and unregister
- SMP, no hotplug, core: register as __init, unregister stubbed
      (cpus are brought up during core initialization)
- SMP, no hotplug, module: register and unregister stubbed out
      (cpus cannot be brought up during module lifetime)

Like the inline code it replaces, this function decaches the vmcs from the cpu
it last executed on.  in addition:

 - vcpu_clear() works if the last cpu is also the cpu we're running on
 - it is faster on larger smps by virtue of using smp_call_function_single()

Includes fix from Ingo Molnar.

Subject: [PATCH 1898/1971] [PATCH] KVM: Host suspend/resume support

Add the necessary callbacks to suspend and resume a host running kvm.  This is
just a repeat of the cpu hotplug/unplug work.

Subject: [PATCH 1899/1971] [PATCH] fbdev driver for S3 Trio/Virge

Add a driver for S3 Trio / S3 Virge.  Driver is tested with most versions
of S3 Trio and with S3 Virge/DX, on i386.

(akpm: We kind-of have support for this hardware already, but...

virgefb.c
  - amiga/zorro specific,
  - broken (according to Kconfig),
  - uses obsolete/nonexistent interface (struct display_switch)
  - recent Adrian Bunk's patch removes this driver

S3triofb.c
  - ppc/openfirmware specific
  - minimal functionality
  - broken (according to Kconfig),
  - uses obsolete/nonexistent interface (struct display_switch)
)

+	s3fb - fbdev driver for S3 Trio/Virge chips
+	===========================================
+
+
+Supported Hardware
+==================
+
+	S3 Trio32
+	S3 Trio64 (and variants V+, UV+, V2/DX, V2/GX)
+	S3 Virge  (and variants VX, DX, GX and GX2+)
+	S3 Plato/PX		(completely untested)
+	S3 Aurora64V+		(completely untested)
+
+	- only PCI bus supported
+	- only BIOS initialized VGA devices supported
+	- probably not working on big endian
+
+I tested s3fb on Trio64 (plain, V+ and V2/DX) and Virge (plain, VX, DX),
+all on i386.
+
+
+Supported Features
+==================
+
+	*  4 bpp pseudocolor modes (with 18bit palette, two variants)
+	*  8 bpp pseudocolor mode (with 18bit palette)
+	* 16 bpp truecolor modes (RGB 555 and RGB 565)
+	* 24 bpp truecolor mode (RGB 888) on (only on Virge VX)
+	* 32 bpp truecolor mode (RGB 888) on (not on Virge VX)
+	* text mode (activated by bpp = 0)
+	* interlaced mode variant (not available in text mode)
+	* doublescan mode variant (not available in text mode)
+	* panning in both directions
+	* suspend/resume support
+	* DPMS support
+
+Text mode is supported even in higher resolutions, but there is limitation
+to lower pixclocks (maximum between 50-60 MHz, depending on specific hardware).
+This limitation is not enforced by driver. Text mode supports 8bit wide fonts
+only (hardware limitation) and 16bit tall fonts (driver limitation).
+
+There are two 4 bpp modes. First mode (selected if nonstd == 0) is mode with
+packed pixels, high nibble first. Second mode (selected if nonstd == 1) is mode
+with interleaved planes (1 byte interleave), MSB first. Both modes support
+8bit wide fonts only (driver limitation).
+
+Suspend/resume works on systems that initialize video card during resume and
+if device is active (for example used by fbcon).
+
+
+Missing Features
+================
+(alias TODO list)
+
+	* secondary (not initialized by BIOS) device support
+   	* big endian support
+	* Zorro bus support
+	* MMIO support
+	* 24 bpp mode support on more cards
+	* support for fontwidths != 8 in 4 bpp modes
+	* support for fontheight != 16 in text mode
+	* composite and external sync (is anyone able to test this?)
+	* hardware cursor
+	* video overlay support
+	* vsync synchronization
+	* feature connector support
+	* acceleration support (8514-like 2D, Virge 3D, busmaster transfers)
+	* better values for some magic registers (performance issues)
+
+
+Known bugs
+==========
+
+	* cursor disable in text mode doesn't work

From e019630e78e3482c2386d18cbdc7a4c54f7a809c Mon Sep 17 00:00:00 2001
From: Adrian Bunk <bunk@stusta.de>
Date: Mon, 12 Feb 2007 00:54:50 -0800
Subject: [PATCH 1900/1971] [PATCH] remove broken video drivers

Remove some video drivers that:

- had already been marked as BROKEN in 2.6.0 three years ago and
- are still marked as BROKEN.

These are the following drivers:
- FB_CYBER
- FB_VIRGE
- FB_RETINAZ3
- FB_SUN3

Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.

But if anyone wants to ever revive any of these drivers, the code is
still present in the older kernel releases.

-* Revision 1.4  1998/09/01 00:31:17  abair
-* Put in a set of default 8,16,24 bpp modes and map cyber8,16 to them.
-* Update operations with 'par' to handle a more complete set of parameter
-* values for encode/decode process.

- * A small info on how to convert XFree86 timing values into fb
- * timings - by Frank Neumann:
- *
-An XFree86 mode line consists of the following fields:
- "800x600"     50      800  856  976 1040    600  637  643  666
- < name >     DCF       HR  SH1  SH2  HFL     VR  SV1  SV2  VFL
-
-The fields in the fb_var_screeninfo structure are:
-        unsigned long pixclock;         * pixel clock in ps (pico seconds) *
-        unsigned long left_margin;      * time from sync to picture    *
-        unsigned long right_margin;     * time from picture to sync    *
-        unsigned long upper_margin;     * time from sync to picture    *
-        unsigned long lower_margin;
-        unsigned long hsync_len;        * length of horizontal sync    *
-        unsigned long vsync_len;        * length of vertical sync      *
-
-1) Pixelclock:
-   xfree: in MHz
-   fb: In Picoseconds (ps)
-
-   pixclock = 1000000 / DCF
-
-2) horizontal timings:
-   left_margin = HFL - SH2
-   right_margin = SH1 - HR
-   hsync_len = SH2 - SH1
-
-3) vertical timings:
-   upper_margin = VFL - SV2
-   lower_margin = SV1 - VR
-   vsync_len = SV2 - SV1
-
-Good examples for VESA timings can be found in the XFree86 source tree,

Subject: [PATCH 1901/1971] [PATCH] tgafb: switch to framebuffer_alloc()

This is a set of changes to update the driver to the framebuffer_alloc() API.
Included, there is also a fix to a memory leak due to the colour map
allocation not being freed upon driver's removal.  Aside from the fix there
are no functional changes.

Subject: [PATCH 1903/1971] [PATCH] tgafb: support the DirectColor visual

 The 32-plane variations of the TGA use the Bt463 RAMDAC and are therefore
DirectColor rather than TrueColor adapters.  This is a set of changes to
implement the necessary bits to support this model.  A couple of fixes to fix
accesses to the RAMDAC are included as a side-effect.

Subject: [PATCH 1916/1971] [PATCH] remove the broken FB_S3TRIO driver

The FB_S3TRIO driver:
- has been marked as BROKEN for more than two years and
- is still marked as BROKEN.

Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.

But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.

From c4f28e54d61278203c2bb2aea0679e0a738235d2 Mon Sep 17 00:00:00 2001
From: Jiri Slaby <jirislaby@gmail.com>
Date: Mon, 12 Feb 2007 00:55:11 -0800
Subject: [PATCH 1917/1971] [PATCH] Video: fb, add true ref_count atomicity

Some of fb drivers uses atomic_t in bad manner, since there are still some
race-prone gaps.  Use mutexes to protect open/close code sections with
ref_count testing and finally use simple uint.

Subject: [PATCH 1922/1971] [PATCH] fbdev modedb: allow refresh rates for named
 video modes

fbdev modedb: Take into account the specified refresh rates for video modes
specified by name, so e.g.  all of `720p', `720p@60', and `720p@50' work.

fb_videomode_to_var(): reset the virtual screen parameters when converting
from an fb_videomode to an fb_var_screeninfo.

Without this the old virtual screen parameters are kept.  Hence you cannot
switch to a video mode with a lower resolution on frame buffer devices that
don't support virtual screens and panning, as values are not supposed to be
rounded down when they don't fit.

I also reordered the assignments to match the order of the individual members.

Subject: [PATCH 1925/1971] [PATCH] ps3: Preallocate bootmem memory for ps3fb

Preallocate bootmem memory for the PS3 frame buffer device, which needs a
large block of physically-contiguous memory. The size of this memory block is
configurable:
  - The config option CONFIG_FB_PS3_DEFAULT_SIZE_M allows to specify the
    default amount of memory (in MiB) allocated to the virtual frame buffer.
  - The early boot parameter `ps3fb=xxx' allows to override the default value.
    It will be rounded up to a multiple of 1 MiB, if needed.

Subject: [PATCH 1926/1971] [PATCH] ps3: Virtual Frame Buffer Driver

Add the PS3 Virtual Frame Buffer Driver.

As the actual graphics hardware cannot be accessed directly by Linux, ps3fb
uses a virtual frame buffer in main memory.  The actual screen image is copied
to graphics memory by the GPU on every vertical blank, by making a hypervisor
call.

Subject: [PATCH 1930/1971] [PATCH] mark struct file_operations const 1

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From 2b8693c0617e972fc0b2fd1ebf8de97e15b656c3 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:32 -0800
Subject: [PATCH 1932/1971] [PATCH] mark struct file_operations const 3

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From fa027c2a0a0d6d1df6b29ee99048502c93da0dd4 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:33 -0800
Subject: [PATCH 1933/1971] [PATCH] mark struct file_operations const 4

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From d54b1fdb1d9f82e375a299e22bd366aad52d4c34 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:34 -0800
Subject: [PATCH 1934/1971] [PATCH] mark struct file_operations const 5

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From 00977a59b951207d38380c75f03a36829950265c Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:34 -0800
Subject: [PATCH 1935/1971] [PATCH] mark struct file_operations const 6

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From 9a32144e9d7b4e21341174b1a83b82a82353be86 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:35 -0800
Subject: [PATCH 1936/1971] [PATCH] mark struct file_operations const 7

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From da7071d7e32d15149cc513f096a3638097b66387 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:36 -0800
Subject: [PATCH 1937/1971] [PATCH] mark struct file_operations const 8

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From 9c2e08c592cd357a8330c34def1e8ecfdcf53275 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:37 -0800
Subject: [PATCH 1938/1971] [PATCH] mark struct file_operations const 9

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From 754661f143e70d66eae6c48532ca245aa05dec0e Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:38 -0800
Subject: [PATCH 1939/1971] [PATCH] mark struct inode_operations const 1

Many struct inode_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From 92e1d5be91a0e3ffa5c4697eeb09b2aa22792122 Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:39 -0800
Subject: [PATCH 1940/1971] [PATCH] mark struct inode_operations const 2

Many struct inode_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

From c5ef1c42c51b1b5b4a401a6517bdda30933ddbaf Mon Sep 17 00:00:00 2001
From: Arjan van de Ven <arjan@linux.intel.com>
Date: Mon, 12 Feb 2007 00:55:40 -0800
Subject: [PATCH 1941/1971] [PATCH] mark struct inode_operations const 3

Many struct inode_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

Subject: [PATCH 1943/1971] [NETFILTER]: Properly use RCU in nf_ct_attach

Use rcu_assign_pointer/rcu_dereference for ip_ct_attach pointer instead
of self-made RCU and use rcu_read_lock to make sure the conntrack module
doesn't disappear below us while calling it, since this function can be
called from outside the netfilter hooks.

 return void

Since the only user of nf_log_unregister_pf (nfnetlink_log) doesn't
check the return value, change it to void and bail out silently when
a non-existant address family is supplied.

Replace preempt_{enable,disable} based RCU by proper use of the
RCU API and add missing rcu_read_lock/rcu_read_unlock calls in
paths used outside of packet processing context (nfnetlink_conntrack).

Subject: [PATCH 1952/1971] [NETFILTER]: nf_nat: properly use RCU API for
 nf_nat_protos array

Replace preempt_{enable,disable} based RCU by proper use of the
RCU API and add missing rcu_read_lock/rcu_read_unlock calls in
paths used outside of packet processing context (nfnetlink_conntrack).

From abbaccda4c364815b8b1a82c45a94f60760e13e1 Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>
Date: Mon, 12 Feb 2007 11:13:14 -0800
Subject: [PATCH 1955/1971] [NETFILTER]: ip_conntrack: fix invalid conntrack
 statistics RCU assumption

CONNTRACK_STAT_INC assumes rcu_read_lock in nf_hook_slow disables
preemption as well, making it legal to use __get_cpu_var without
disabling preemption manually. The assumption is not correct anymore
with preemptable RCU, additionally we need to protect against softirqs
when not holding ip_conntrack_lock.

Add CONNTRACK_STAT_INC_ATOMIC macro, which disables local softirqs,
and use where necessary.

Subject: [PATCH 1959/1971] [NETFILTER]: nf_conntrack: change
 nf_conntrack_l[34]proto_unregister to void

No caller checks the return value, and since its usually called within the
module unload path there's nothing a module could do about errors anyway,
so BUG on invalid conditions and return void.

 names for IPv6 registration

Use NF_IP6_ instead of NF_IP_. The values are identical, this is merely
cleanup.

Subject: [PATCH 1961/1971] [NETFILTER]: Kconfig: improve dependency handling

Instead of depending on internally needed options and letting users
figure out what is needed, select them when needed:

- IP_NF_IPTABLES, IP_NF_ARPTABLES and IP6_NF_IPTABLES select
  NETFILTER_XTABLES

- NETFILTER_XT_TARGET_CONNMARK, NETFILTER_XT_MATCH_CONNMARK and
  IP_NF_TARGET_CLUSTERIP select NF_CONNTRACK_MARK

- NETFILTER_XT_MATCH_CONNBYTES selects NF_CT_ACCT

Subject: [PATCH 1963/1971] [NETFILTER]: ip6t_mh: drop piggyback payload packet
 on MH packets

Regarding RFC3775, MH payload proto field should be IPPROTO_NONE. Otherwise
it must be discarded (and the receiver should send ICMP error).

We assume filter should drop such piggyback everytime to disallow slipping
through firewall rules, even the final receiver will discard it.

Subject: [PATCH 1967/1971] [XFRM]: Fix OOPSes in xfrm_audit_log().

Make sure that this function is called correctly, and
add BUG() checking to ensure the arguments are sane.

Based upon a patch by Joy Latten.

avoid that.

Subject: [PATCH 1971/1971] [SPARC]: Re-export saved_command_line to modules.

This reverts some bogosity from the dynamic command-line
changes made on sparc32 and sparc64.

Drivers such as drivers/sbus/char/openprom.c reference
saved_command_line, and can be modular.

The boot_command_line is __initdata, yet the dynamic command-line
changes add modular exports of that symbol, obviously wrong.
