Subject: [PATCH 006/794] [POWERPC] Create modalias file in sysfs for
 of_platform bus

Create /sys/bus/of_platform/devices/*/modalias file to allow autoloading
of modules.  Modalias files are already present for many other bus types.
This adds also a newline to the devspec files.

Also create a devspec file for mac-io devices.  They were created as a
side effect.  Use correct buffer size for mac-io modalias buffer.

Tested on iBook1 and Efika.

Subject: [PATCH 007/794] [POWERPC] Define and use TLF_RESTORE_SIGMASK

Replace TIF_RESTORE_SIGMASK with TLF_RESTORE_SIGMASK and define
our own set_restore_sigmask() function.  This saves the costly
SMP-safe set_bit operation, which we do not need for the sigmask
flag since TIF_SIGPENDING always has to be set too.

Subject: [PATCH 008/794] [POWERPC] Set lower flag bits in regs->trap to
 indicate debug level exception

We use the low bits of regs->trap as flag bits.  We already indicate
critical and machine check level exceptions via this mechanism.  Extend it
to indicate debug level exceptions.

Subject: [PATCH 009/794] [POWERPC] Create of_buses for MV64x60 devices

For each mv64360 entry in the OpenFirmware database, add the
registration of an of_bus to take care of devices connected to
the MV64x60 asynchronous devices controller.
This change makes it possible for those devices to be detected by
drivers that support the of_platform without having a custom call
for each of them in the board file.

Somewhere along the way (e28f7faf05159f1cfd564596f5e6178edba6bd49,
"Four level pagetables for ppc64") we ended up with duplicate
definitions for pte_freelist_cur and pte_freelist_force_free.
Somehow this compiles, but it would be better to just have one
definition for each.

The two definitions we end up with can be static too!

Subject: [PATCH 018/794] [POWERPC] Make cpus_in_xmon static and remove extern
 mess from hvc_console.c

This is a little messier than I'd like because xmon.h only exists
on powerpc and we can't have a static inline and an extern declaration
visible at the same time.

Subject: [PATCH 020/794] [POWERPC] pseries/firmware.c should include
 pseries/pseries.h

The declaration for fw_feature_init() is in pseries.h and
implemented in firmware.c, so the latter should include the
former.

Subject: [PATCH 022/794] [POWERPC] Defer processing of interrupts when the CPU
 wakes from sleep mode

This provides a way to defer processing of an interrupt that wakes the
processor out of sleep mode.  On 32-bit platforms that use an
interrupt to wake the processor, we have to have interrupts enabled in
hardware at the point where we go to sleep, otherwise the processor
will never wake up.  However, because interrupts are logically
disabled at this point, we don't want to process the interrupt
straight away.

This is handled by setting the _TLF_SLEEPING flag.  When we get an
interrupt and _TLF_SLEEPING is set, we firstly clear the MSR_EE
(external interrupt enable) bit in the saved MSR value, and secondly
we then return to the address in the link register, like we do for
_TLF_NAPPING, but without actually handling the interrupt.

Note that this is handled somewhat differently on powerbooks, so this
new code will only be used on non-Apple machines.

Subject: [PATCH 023/794] [POWERPC] Add 6xx-style HID0_SLEEP support.

This adds a function to put a 6xx/7xx/7xxx/83xx family CPU into sleep
mode, and return after an interrupt has occurred.  It expects to be
called with interrupts disabled, and returns with interrupts disabled.
Interrupts are enabled while the processor is asleep, but the interrupt
that wakes the processor is not handled; it is still pending when this
function returns.

Subject: [PATCH 025/794] [POWERPC] Move of_device_get_modalias to drivers/of

Commit 140b932f8cb6cced10b96860651a198b1b89cbb9 ("Create modalias file
in sysfs for of_platform bus") needs this to avoid breaking the sparc
builds.

Just move the code and add whitespace around some binary operators.

Subject: [PATCH 026/794] rcupreempt: remove duplicate prototypes

rcu_batches_completed and rcu_patches_completed_bh are both declared
in rcuclassic.h and rcupreempt.h. This patch removes the extra
prototypes for them from rcupdate.h.

rcu_batches_completed_bh is defined as a static inline in the rcupreempt.h
header file. Trying to export this as EXPORT_SYMBOL_GPL causes linking problems
with the powerpc linker. There's no need to export a static inlined function.

Modules must be compiled with the same type of RCU implementation as the
kernel they are for.

Subject: [PATCH 027/794] rcu: add call_rcu_sched()

Fourth cut of patch to provide the call_rcu_sched().  This is again to
synchronize_sched() as call_rcu() is to synchronize_rcu().

Should be fine for experimental and -rt use, but not ready for inclusion.
With some luck, I will be able to tell Andrew to come out of hiding on
the next round.

Passes multi-day rcutorture sessions with concurrent CPU hotplugging.

Fixes since the first version include a bug that could result in
indefinite blocking (spotted by Gautham Shenoy), better resiliency
against CPU-hotplug operations, and other minor fixes.

Fixes since the second version include reworking grace-period detection
to avoid deadlocks that could happen when running concurrently with
CPU hotplug, adding Mathieu's fix to avoid the softlockup messages,
as well as Mathieu's fix to allow use earlier in boot.

Fixes since the third version include a wrong-CPU bug spotted by
Andrew, getting rid of the obsolete synchronize_kernel API that somehow
snuck back in, merging spin_unlock() and local_irq_restore() in a
few places, commenting the code that checks for quiescent states based
on interrupting from user-mode execution or the idle loop, removing
some inline attributes, and some code-style changes.

Known/suspected shortcomings:

o	I still do not entirely trust the sleep/wakeup logic.  Next step
	will be to use a private snapshot of the CPU online mask in
	rcu_sched_grace_period() -- if the CPU wasn't there at the start
	of the grace period, we don't need to hear from it.  And the
	bit about accounting for changes in online CPUs inside of
	rcu_sched_grace_period() is ugly anyway.

o	It might be good for rcu_sched_grace_period() to invoke
	resched_cpu() when a given CPU wasn't responding quickly,
	but resched_cpu() is declared static...

This patch also fixes a long-standing bug in the earlier preemptable-RCU
implementation of synchronize_rcu() that could result in loss of
concurrent external changes to a task's CPU affinity mask.  I still cannot
remember who reported this...

Subject: [PATCH 028/794] rcu: add memory barriers and comments to
 rcu_check_callbacks()

Add comments to the logic that infers quiescent states when interrupting
from either user mode or the idle loop.  Also add a memory barrier: it
appears that James Huang was in fact onto something, as the scheduler
is much less synchronization happy than it once was, so we can no longer
rely on its memory barriers in all cases.

Add rcu_barrier_sched() and rcu_barrier_bh().  With these in place,
rcutorture no longer gives the occasional oops when repeatedly starting
and stopping torturing rcu_bh.  Also adds the API needed to flush out
pre-existing call_rcu_sched() callbacks.

From 82524746c27fa418c250a56dd7606b9d3fc79826 Mon Sep 17 00:00:00 2001
From: Franck Bui-Huu <fbuihuu@gmail.com>
Date: Mon, 12 May 2008 21:21:05 +0200
Subject: [PATCH 032/794] rcu: split list.h and move rcu-protected lists into
 rculist.h

Move rcu-protected lists from list.h into a new header file rculist.h.

This is done because list are a very used primitive structure all over the
kernel and it's currently impossible to include other header files in this
list.h without creating some circular dependencies.

For example, list.h implements rcu-protected list and uses rcu_dereference()
without including rcupdate.h.  It actually compiles because users of
rcu_dereference() are macros.  Others RCU functions could be used too but
aren't probably because of this.

Therefore this patch creates rculist.h which includes rcupdates without to
many changes/troubles.

From: Franck Bui-Huu <fbuihuu@gmail.com>
Date: Mon, 12 May 2008 21:21:06 +0200
Subject: [PATCH 033/794] rculist.h: use the rcu API

Make almost all list mutation primitives use rcu_assign_pointer().

The main point of this being readability improvement.

Subject: [PATCH 034/794] rcu: fix rcu_try_flip_waitack_needed() to prevent
 grace-period stall

The comment was correct -- need to make the code match the comment.
Without this patch, if a CPU goes dynticks idle (and stays there forever)
in just the right phase of preemptible-RCU grace-period processing,
grace periods stall.  The offending sequence of events (courtesy
of Promela/spin, at least after I got the liveness criterion coded
correctly...) is as follows:

o	CPU 0 is in dynticks-idle mode.  Its dynticks_progress_counter
	is (say) 10.

o	CPU 0 takes an interrupt, so rcu_irq_enter() increments CPU 0's
	dynticks_progress_counter to 11.

o	CPU 1 is doing RCU grace-period processing in rcu_try_flip_idle(),
	sees rcu_pending(), so invokes dyntick_save_progress_counter(),
	which in turn takes a snapshot of CPU 0's dynticks_progress_counter
	into CPU 0's rcu_dyntick_snapshot -- now set to 11.  CPU 1 then
	updates the RCU grace-period state to rcu_try_flip_waitack().

o	CPU 0 returns from its interrupt, so rcu_irq_exit() increments
	CPU 0's dynticks_progress_counter to 12.

o	CPU 1 later invokes rcu_try_flip_waitack(), which notices that
	CPU 0 has not yet responded, and hence in turn invokes
	rcu_try_flip_waitack_needed().  This function examines the
	state of CPU 0's dynticks_progress_counter and rcu_dyntick_snapshot
	variables, which it copies to curr (== 12) and snap (== 11),
	respectively.

	Because curr!=snap, the first condition fails.

	Because curr-snap is only 1 and snap is odd, the second
	condition fails.

	rcu_try_flip_waitack_needed() therefore incorrectly concludes
	that it must wait for CPU 0 to explicitly acknowledge the
	counter flip.

o	CPU 0 remains forever in dynticks-idle mode, never taking
	any more hardware interrupts or any NMIs, and never running
	any more tasks.  (Of course, -something- will usually eventually
	happen, which might be why we haven't seen this one in the
	wild.  Still should be fixed!)

Therefore the grace period never ends.  Fix is to make the code match
the comment, as shown below.  With this fix, the above scenario
would be satisfied with curr being even, and allow the grace period
to proceed.

we can use dynamic GPIO base allocation now.

This, in turn, removes number of gpios per chip constraint.

Add a flag that board code can set to just use irq_count instead of

Subject: [PATCH 044/794] [POWERPC] Add debugging trigger to Axon MSI code

This adds some debugging code to the Axon MSI driver.  It creates a
file per MSIC in /sys/kernel/debug/powerpc, which allows the user to
trigger a fake MSI interrupt by writing to the file.

This can be used to test some of the MSI generation path.  In
particular, that the MSIC recognises a write to the MSI address,
generates an interrupt and writes the MSI packet into the ring buffer.

All the code is inside #ifdef DEBUG so it causes no harm unless it's
enabled.

 structs

This patch makes the stacktrace printout code \warn when the entries
pointer is unset rather than crashing when trying to access it in an
attempt to make it a bit more robust.

I was saving a stacktrace into an skb and forgot to copy it across skb
copies... I have since fixed the code, but it would have been easier
had the kernel not crashed in an interrupt.

Subject: [PATCH 049/794] hrtimer: remove warning in hres_timers_resume

hres_timers_resume() warns if there appears to be more than one cpu
online.  This warning makes sense when the suspend/resume mechanism
offlines all cpus but one during the suspend/resume process.

However, Xen suspend does not need to offline the other cpus; it
merely keeps them tied up in stop_machine() while the virtual machine
is suspended.  The warning hres_timers_resume issues is therefore
spurious.

Subject: [PATCH 052/794] [POWERPC] Refactor DCR code

Previously, DCR support was configured at compile time to either use
MMIO or native dcr instructions.  Although this works for most
platforms, it fails on FPGA platforms:

1) Systems may include more than one DCR bus.
2) Systems may be native DCR capable and still use memory mapped DCR interface.

This patch provides runtime support based on the device trees for the
case where CONFIG_PPC_DCR_MMIO and CONFIG_PPC_DCR_NATIVE are both
selected.  Previously, this was a poorly defined configuration, which
happened to provide NATIVE support.  The runtime selection is made
based on the dcr-controller having a 'dcr-access-method' attribute
in the device tree.  If only one of the above options is selected,
then the code uses #defines to select only the used code in order to
avoid introducing overhead in existing usage.

From 71f349799b34c8b6ce3df42126b4de6cfa16456d Mon Sep 17 00:00:00 2001

Subject: [PATCH 053/794] [POWERPC] Convert remaining dts-v0 files to v1

At the moment we have a mixture of left-over version 0 and new-format
version 1 files in arch/powerpc/boot/dts.  This is potentially
confusing to people new to the dts format attempting to figure it out.

So, this patch converts all the as-yet unconverted dts v0 files and
converts them to v1.  They're mechanically-converted, and not hand
tweaked so in some cases they're not 100% in keeping with usual v1
style, but the convertor program does have some heuristics so the
discrepancies aren't too bad.

I have checked that this patch produces no changes to the resulting
dtb binaries.

Subject: [PATCH 054/794] [POWERPC] 4xx: Fix PCI mem in rainier DTS

This fixes the PCI node in the Rainier to match the spec from AMCC.  A
similar fix was done for 440EPx, which shares the same values as 440GRx.

Subject: [PATCH 057/794] [POWERPC] 4xx: Fix compiler warning on DCR_NATIVE
 only builds

With the recent DCR code rework, we get a compiler warning about
find_dcr_parent being defined but not used.  This fixes it by only defining
the function if CONFIG_PPC_DCR_MMIO is set.

Subject: [PATCH 060/794] [POWERPC] fsl: PCIe MSI support for 83xx/85xx/86xx
 processors.

This MSI driver can be used on 83xx/85xx/86xx board.
In this driver, virtual interrupt host and chip were
setup. There are 256 MSI interrupts in this host, Every 32
MSI interrupts cascaded to one IPIC/MPIC interrupt.
The chip was treated as edge sensitive and some necessary
functions were setup for this chip.

Before using the MSI interrupt, PCI/PCIE device need to
ask for a MSI interrupt in the 256 MSI interrupts. A 256bit
bitmap show which MSI interrupt was used, reserve bit in
the bitmap can be used to force the device use some designate
MSI interrupt in the 256 MSI interrupts. Sometimes this is useful
for testing the all the MSI interrupts. The msi-available-ranges
property in the dts file was used for this purpose.

Subject: [PATCH 064/794] [POWERPC] fsl: Add warning for unrecognized I2C nodes
 in the device tree

Update of_find_i2c_driver in fsl_soc.c to display a warning message if an
I2C node in the device tree isn't found in the i2c_devices[] array.

Subject: [PATCH 065/794] [POWERPC] fsl: Add CS4270 i2c data to fsl_soc.c

The i2c_devices[] array in fsl_soc.c lists all the I2C nodes that are supported
on Freescale boards.  Add an entry for the Cirrus Logic CS4270 so that a
new-style CS4270 driver will work.

From acd4b715ec83e451990bb82bdbf28ecaeab1b67d Mon Sep 17 00:00:00 2001
From: Kumar Gala <galak@kernel.crashing.org>
Date: Fri, 30 May 2008 12:12:26 -0500
Subject: [PATCH 067/794] [POWERPC] Cleanup mpic nodes in .dts

Removed clock-frequency, big-endian, and built-in props as they aren't
specified anywhere.  Also added compatible = "chrp,open-pic" in the
places it was missing.

Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

From c054065bc10a7ee2bcf78b5bc95f4b4d9bdc923a Mon Sep 17 00:00:00 2001
From: Kumar Gala <galak@kernel.crashing.org>
Date: Fri, 30 May 2008 13:43:43 -0500
Subject: [PATCH 068/794] [POWERPC] 85xx: Add next-level-cache property

Added next-level-cache to the L1 and a reference to the new L2 label.
This is per the ePAPR 0.94 spec.  Since we are't really dependent on this
today we aren't supporting the "legacy" l2-cache phandle that is specified
in the PPC v2.1 OF Binding spec.

Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

From bcf0b0880710409420a4e3b15dbf4b9a63542c0b Mon Sep 17 00:00:00 2001

Date: Wed, 30 Apr 2008 03:49:55 -0500
Subject: [PATCH 069/794] [POWERPC] Move to runtime allocated exception stacks

For the additonal exception levels (critical, debug, machine check) on
40x/book-e we were using "static" allocations of the stack in the
associated head.S.

Move to a runtime allocation to make the code a bit easier to read as
we mimic how we handle IRQ stacks.  Its also a bit easier to setup the
stack with a "dummy" thread_info in C code.

Subject: [PATCH 070/794] [POWERPC] Rework EXC_LEVEL_EXCEPTION_PROLOG code

* Cleanup the code a bit my allocating an INT_FRAME on our exception
  stack there by make references go from GPR11-INT_FRAME_SIZE(r8) to
  just GPR11(r8)
* simplify {lvl}_transfer_to_handler code by moving the copying of the
  temp registers we use if we come from user space into the PROLOG
* If the exception came from kernel mode copy thread_info flags,
  preempt, and task pointer from the process thread_info.

Subject: [PATCH 071/794] [POWERPC] 40x/Book-E: Save/restore volatile exception
 registers

On machines with more than one exception level any system register that
might be modified by the "normal" exception level needs to be saved and
restored on taking a higher level exception.  We already are saving
and restoring ESR and DEAR.

For critical level add SRR0/1.
For debug level add CSRR0/1 and SRR0/1.
For machine check level add DSRR0/1, CSRR0/1, and SRR0/1.

On FSL Book-E parts we always save/restore the MAS registers for critical,
debug, and machine check level exceptions.  On 44x we always save/restore
the MMUCR.

Additionally, we save and restore the ksp_limit since we have to adjust it
for each exception level.

Subject: [PATCH 072/794] [POWERPC] fsl: Update fsl_soc to use cell-index
 property of I2C nodes

Currently, fsl_i2c_of_init() uses the order of the I2C adapter nodes in the
device tree to enumerate the I2C adapters.  Instead, let's check for the
cell-index property and use it if it exists.

This is handy for device drivers that need to identify the I2C adapters by
specific numbers.  The Freescale MPC8610 ASoC V2 sound drivers are an example.

Subject: [PATCH 073/794] genirq: Expose default irq affinity mask (take 3)

Current IRQ affinity interface does not provide a way to set affinity
for the IRQs that will be allocated/activated in the future.
This patch creates /proc/irq/default_smp_affinity that lets users set
default affinity mask for the newly allocated IRQs. Changing the default
does not affect affinity masks for the currently active IRQs, they
have to be changed explicitly.

Updated based on Paul J's comments and added some more documentation.

 /proc/irq/IRQ#/smp_affinity specifies which target CPUs are permitted
 for a given IRQ source. It's a bitmask of allowed CPUs. It's not allowed
 to turn off all CPUs, and if an IRQ controller does not support IRQ
 affinity then the value will not change from the default 0xffffffff.
 
+/proc/irq/default_smp_affinity specifies default affinity mask that applies
+to all non-active IRQs. Once IRQ is allocated/activated its affinity bitmask
+will be set to the default mask. It can then be changed as described above.
+Default mask is 0xffffffff.
+
 Here is an example of restricting IRQ44 (eth1) to CPU0-3 then restricting
-the IRQ to CPU4-7 (this is an 8-CPU SMP box):

 Of some interest is the introduction of the /proc/irq directory to 2.4.
 It could be used to set IRQ to CPU affinity, this means that you can "hook" an
 IRQ to only one CPU, or to exclude a CPU of handling IRQs. The contents of the
-irq subdir is one subdir for each IRQ, and one file; prof_cpu_mask
+irq subdir is one subdir for each IRQ, and two files; default_smp_affinity and
+prof_cpu_mask.
 
 For example 
   > ls /proc/irq/

+smp_affinity is a bitmask, in which you can specify which CPUs can handle the
+IRQ, you can set it by doing:
 
-  > cat /proc/irq/0/smp_affinity 
-  ffffffff

+This means that only the first CPU will handle the IRQ, but you can also echo
+5 which means that only the first and fourth CPU can handle the IRQ.

 The way IRQs are routed is handled by the IO-APIC, and it's Round Robin
 between all the CPUs which are allowed to handle it. As usual the kernel has

Subject: [PATCH 074/794] [SCSI] scsi_dh: add infrastructure for SCSI Device
 Handlers

Some of the storage devices (that can be accessed through multiple paths),
do need some special handling for
	1. Activating the passive path of the storage access.
	2. Decode and handle the special sense codes returned by the devices.
	3. Handle the I/Os being sent to the passive path, especially
           during the device probe time.
when accessed through multiple paths.

As of today this special device handling is done at the dm-multipath
layer using dm-handlers. That works well for (1); for (2) to be handled
at dm layer, scsi sense information need to be exported from SCSI to dm-layer,
which is not very attractive; (3) cannot be done at all at the dm layer.

Device handler has been moved to SCSI mainly to handle (2) and (3) properly.

From cfae5c9bb66325cd32d5f2ee41f14749f062a53c Mon Sep 17 00:00:00 2001
From: Chandra Seetharaman <sekharan@us.ibm.com>
Date: Thu, 1 May 2008 14:50:11 -0700
Subject: [PATCH 078/794] [SCSI] scsi_dh: Use SCSI device handler in
 dm-multipath

This patch converts dm-mpath to use scsi device handlers instead of
dm's hardware handlers.

This patch does not add any new functionality. Old behaviors remain and
userspace tools work as is except that arguments supplied with hardware
handler are ignored.

One behavioral exception is: Activation of a path is synchronous in this
patch, opposed to the older behavior of being asynchronous (changed in
patch 07: scsi_dh: Add a single threaded workqueue for initializing a path)

Note: There is no need to get a reference for the device handler module
(as it was done in the dm hardware handler case) here as the reference
is held when the device was first found. Instead we check and make sure
that support for the specified device is present at table load time.

Subject: [PATCH 079/794] [SCSI] scsi_dh: Add a single threaded workqueue for
 initializing paths

Before this patch set (SCSI hardware handlers), initialization of a
path was done asynchronously. Doing that requires a workqueue in each
device/hardware handler module and leads to unneccessary complication
in the device handler code, making it difficult to read the code and
follow the state diagram.

Moving that workqueue to this level makes the device handler code simpler.
Hence, the workqueue is moved to dm level.

A new workqueue is added instead of adding it to the existing workqueue
(kmpathd) for the following reasons:
	1. Device activation has to happen faster, stacking them along
	   with the other workqueue might lead to unnecessary delay
	   in the activation of the path.
	2. The effect could be felt the other way too. i.e the current
	   events that are handled by the existing workqueue might get
	   a delayed response.

This patch just removes the dm layer's path initialization completion
routine.  This is separated from the other patch(scsi_dh: Use SCSI
device handler in dm-multipath) Just to make that patch more readable.

Date: Tue, 6 May 2008 11:00:06 +0200
Subject: [PATCH 084/794] [SCSI] zfcp: sysfs attributes for fabric and channel
 latencies
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The latency information is provided on a SCSI device level (LUN)
which can be found at the following location

 /sys/class/scsi_device/<H:C:T:L>/device/cmd_latency
 /sys/class/scsi_device/<H:C:T:L>/device/read_latency
 /sys/class/scsi_device/<H:C:T:L>/device/write_latency

Each sysfs attribute provides the available data: min, max and sum for
fabric and channel latency and the number of requests processed.

An overrun of the variables is neither detected nor treated.  The file
has to be read twice to make a meaningful statement, because only the
differences of the values between the two reads can be used.  A reset
of the values can be achieved by writing to the attribute.

Subject: [PATCH 088/794] [SCSI] make use of the residue value

USB sometimes doesn't return an error but instead returns a residue
value indicating part (or all) of the command wasn't completed.  So if
the driver _done() error processing indicates the command was fully
processed, subtract off the residue so that this USB error gets
propagated.

Subject: [PATCH 090/794] [SCSI] zfcp: receiving an unsolicted status can lead
 to I/O stall

Processing of an unsolicted status request can lead to a locking race
of the request_queue's queue_lock during the recreation of the
used up status read request while still in interrupt context
of the response handler.

Detaching the 'refill' of the long running status read requests from
the handler to a scheduled work is solving this issue.

In addition, each refill-run is trying to re-establish the full amount
of status read requests, which might have failed in earlier runs.

Subject: [PATCH 091/794] [SCSI] zfcp: Fix mempool pointer for GID_PN request
 allocation

When allocating memory for GID_PN nameserver requests, the allocation
function stores the pointer to the mempool, but then overwrites the
pointer via memset. Later, the wrong function to free the memory will
be called, since this is based on the stored pointer.

Fix this by first initializing the struct and then storing the pointer.

From d01d51beee4dd9f7ff9caf7491aa1727a318e665 Mon Sep 17 00:00:00 2001

Date: Mon, 19 May 2008 12:17:42 +0200
Subject: [PATCH 095/794] [SCSI] zfcp: Rename sbal_last.

sbal_last is confusing, as it is not the last one actually used,
but just a limit. sbal_limit is a better name.

Subject: [PATCH 096/794] [SCSI] zfcp: Rename sbal_curr to sbal_last.

sbal_last is more appropriate, because it matches sbal_first.

Subject: [PATCH 097/794] [SCSI] zfcp: Add information about interrupt to
 trace.

Store the index of the buffer in the inbound queue used to report
request completion in trace record for request coompletion.
This piece of information allows to better compare qdio and zfcp traces.

Subject: [PATCH 098/794] [SCSI] zfcp: Refine trace levels of some recovery
 related events.

This change better spreads trace levels of recovery related events.
There was an overlap of traces for some recovery triggers and the
processing of recovery actions.

Subject: [PATCH 099/794] [SCSI] zfcp: remove some __attribute__ ((packed))

There is no need to pack data structures which describe the
contents of records in the new recovery trace.

lcrash currently depends on the binary format for the other traces,
removing the packed attribute from all traces would break trace
debugging with lcrash.

'zfcp_rec_dbf_event_thread' - different lock contexts for basic block

Replace the parameter indicating if the lock is held with a new entry
function that only acquires the lock. This makes the lock handling
more visible and removes the sparse warning.

Subject: [PATCH 104/794] powerpc: DTS file for the C2K

Support for the C2K cPCI Single Board Computer from GEFanuc
(PowerPC MPC7448 with a Marvell MV64460 chipset).
All features of the board are not supported yet, but the board
boots, flash works, all Ethernet ports are working and PCI
devices are all found (USB and SATA on PCI1 do not work yet).

Part 1 of 5: DTS file describing the board peripherals.  As far as I
know all peripherals except the FPGA are listed in there (I did not
include the FPGA because a lot of work is needed there).

Subject: [PATCH 105/794] powerpc: Boot code for the C2K

Support for the C2K cPCI Single Board Computer from GEFanuc
(PowerPC MPC7448 with a Marvell MV64460 chipset).
All features of the board are not supported yet, but the board
boots, flash works, all Ethernet ports are working and PCI
devices are all found (USB and SATA on PCI1 do not work yet).

Part 2 of 5: support for the board in arch/powerpc/boot.

Subject: [PATCH 106/794] powerpc: C2K board driver

Support for the C2K cPCI Single Board Computer from GEFanuc
(PowerPC MPC7448 with a Marvell MV64460 chipset).
All features of the board are not supported yet, but the board
boots, flash works, all Ethernet ports are working and PCI
devices are all found (USB and SATA on PCI1 do not work yet).

Part 3 of 5: driver for the board.  At this time it is very generic
and similar to its original, the driver for the prpmc2800.

Support for the C2K cPCI Single Board Computer from GEFanuc

All features of the board are not supported yet, but the board
boots, flash works, all Ethernet ports are working and PCI
devices are all found (USB and SATA on PCI1 do not work yet).

Part 4 of 5: this is the default config for the board.  In this
configuration the kernel is going to try to boot from MTD
partition 3 on the NOR flash (see c2k.dts for details about
the partitioning of the flash).

Subject: [PATCH 108/794] powerpc: Add C2K to configuration

Support for the C2K cPCI Single Board Computer from GEFanuc
(PowerPC MPC7448 with a Marvell MV64460 chipset).
All features of the board are not supported yet, but the board
boots, flash works, all Ethernet ports are working and PCI
devices are all found (USB and SATA on PCI1 do not work yet).

Part 5 of 5: add the Kconfig entry for the C2K board.

Subject: [PATCH 112/794] powerpc: Check that TASK_SIZE does not overlap
 KERNEL_START

Make sure CONFIG_TASK_SIZE does not overlap CONFIG_KERNEL_START
This could happen when overriding settings to get 1GB lowmem, and would lead
to userland mysteriousely hanging.

Subject: [PATCH 116/794] powerpc: Fix irq_alloc_host() reference counting and
 callers

When I changed irq_alloc_host() to take an of_node
(52964f87c64e6c6ea671b5bf3030fb1494090a48: "Add an optional
device_node pointer to the irq_host"), I botched the reference
counting semantics.

Stephen pointed out that it's irq_alloc_host()'s business if
it needs to take an additional reference to the device_node,
the caller shouldn't need to care.

From: Trent Piepho <tpiepho@freescale.com>

Subject: [PATCH 117/794] powerpc: Improve (in|out)_[bl]eXX() asm code

Since commit 4cb3cee03d558fd457cb58f56c80a2a09a66110c the code generated
for the in_beXX() and out_beXX() mmio functions has been sub-optimal.

The out_leXX() family of functions are created with the macro
DEF_MMIO_OUT_LE() while the out_beXX() family are created with
DEF_MMIO_OUT_BE().  In what was perhaps a bit too much macro use, both of
these macros are in turn created via the macro DEF_MMIO_OUT().

For the LE versions, eventually they boil down to an asm that will look
something like this:
asm("sync; stwbrx %1,0,%2" : "=m" (*addr) : "r" (val), "r" (addr));

The issue is that the "stwbrx" instruction only comes in an indexed, or
'x', version, in which the address is represented by the sum of two
registers (the "0,%2").  Unfortunately, gcc doesn't have a constraint for
an indexed memory reference.  The "m" constraint allows both indexed and
offset, i.e. register plus constant, memory references and there is no
"stwbr" version for offset references.  "m" also allows updating addresses
and there is no 'u' version of "stwbrx" like there is with "stwux".

The unused first operand to the asm is just to tell gcc that *addr is an
output of the asm.  The address used is passed in a single register via the
third asm operand, and the index register is just hard coded as 0.  This
means gcc is forced to put the address in a single register and can't use
index addressing, e.g. if one has the data in register 9, a base address in
register 3 and an index in register 4, gcc must emit code like "add 11,4,3;
stwbrx 9,0,11" instead of just "stwbrx 9,4,3".  This costs an extra add
instruction and another register.

For gcc 4.0 and older, there doesn't appear to be anything that can be
done.  But for 4.1 and newer, there is a 'Z' constraint.  It does not allow
"updating" addresses, but does allow both indexed and offset addresses.
However, the only allowed constant offset is 0.  We can then use the
undocumented 'y' operand modifier, which causes gcc to convert "0(reg)"
into the equivilient "0,reg" format that can be used with stwbrx.

This brings us the to problem with the BE version.  In this case, the "stw"
instruction does have both indexed and non-indexed versions.  The final asm
ends up looking like this:
asm("sync; stw%U0%X0 %1,%0" : "=m" (*addr) : "r" (val), "r" (addr));

The undocumented codes "%U0" and "%0X" will generate a 'u' if the memory
reference should be an auto-updating one, and an 'x' if the memory
reference is indexed, respectively.  The third operand is unused, it's just
there because asm the code is reused from the LE version.  However, gcc
does not know this, and generates unnecessary code to stick addr in a
register!  To use the example from the LE version, gcc will generate "add
11,4,3; stwx 9,4,3".  It is able to use the indexed address "4,3" for the
"stwx", but still thinks it needs to put 4+3 into register 11, which will
never be used.

This also ends up happening a lot for the offset addressing mode, where
common code like this:  out_be32(&device_registers->some_register, data);
uses an instruction like "stw 9, 42(3)", where register 3 has the pointer
device_registers and 42 is the offset of some_register in that structure.
gcc will be forced to generate the unnecessary instruction "addi 11, 3, 42"
to put the address into a single (unused) register.

The in_* versions end up having these exact same problems as well.

- * Buffer descriptors are kept in the CPM dual port RAM, and the frame

- * pages and then divide them into 2K frame buffers.  This way I know I
- * have buffers large enough to hold one frame within one buffer descriptor.
- * Once I get this working, I will use 64 or 128 byte CPM buffers, which

- *				Theory of Operation
- *
- * The MPC8260 CPM performs the Ethernet processing on an SCC.  It can use
- * an aribtrary number of buffers on byte boundaries, but must have at
- * least two receive buffers to prevent constant overrun conditions.
- *
- * The buffer descriptors are allocated from the CPM dual port memory
- * with the data buffers allocated from host memory, just like all other
- * serial communication protocols.  The host memory buffers are allocated
- * from the free page pool, and then divided into smaller receive and
- * transmit buffers.  The size of the buffers should be a power of two,
- * since that nicely divides the page.  This creates a ring buffer
- * structure similar to the LANCE and other controllers.
- *
- * Like the LANCE driver:
- * The driver runs as two independent, single-threaded flows of control.  One
- * is the send-packet routine, which enforces single-threaded use by the
- * cep->tx_busy flag.  The other thread is the interrupt handler, which is
- * single threaded by the hardware and other software.

-/*
- * Fast Ethernet Controller (FCC) driver for Motorola MPC8260.
- * Copyright (c) 2000 MontaVista Software, Inc.   Dan Malek (dmalek@jlc.net)
- *
- * This version of the driver is a combination of the 8xx fec and
- * 8260 SCC Ethernet drivers.  This version has some additional
- * configuration options, which should probably be moved out of
- * here.  This driver currently works for the EST SBC8260,
- * SBS Diablo/BCM, Embedded Planet RPX6, TQM8260, and others.
- *
- * Right now, I am very watseful with the buffers.  I allocate memory
- * pages and then divide them into 2K frame buffers.  This way I know I
- * have buffers large enough to hold one frame within one buffer descriptor.
- * Once I get this working, I will use 64 or 128 byte CPM buffers, which
- * will be much more memory efficient and will easily handle lots of
- * small packets.  Since this is a cache coherent processor and CPM,
- * I could also preallocate SKB's and use them directly on the interface.
- *
- * 2004-12	Leo Li (leoli@freescale.com)
- * - Rework the FCC clock configuration part, make it easier to configure.

- * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
- *
- * In addition to the individual control of the communication
- * channels, there are a few functions that globally affect the
- * communication processor.
- *
- * Buffer descriptors must be allocated from the dual ported memory
- * space.  The allocator for that is here.  When the communication
- * 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.

- * Ethernet driver for Motorola MPC8xx.
- * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
- *
- * I copied the basic skeleton from the lance driver, because I did not
- * know how to write the Linux driver, but I did know how the LANCE worked.
- *
- * This version of the driver is somewhat selectable for the different
- * processor/board combinations.  It works for the boards I know about
- * now, and should be easily modified to include others.  Some of the
- * configuration information is contained in <asm/cpm1.h> and the
- * remainder is here.
- *
- * Buffer descriptors are kept in the CPM dual port RAM, and the frame
- * buffers are in the host memory.
- *
- * Right now, I am very watseful with the buffers.  I allocate memory
- * pages and then divide them into 2K frame buffers.  This way I know I
- * have buffers large enough to hold one frame within one buffer descriptor.
- * Once I get this working, I will use 64 or 128 byte CPM buffers, which
- * will be much more memory efficient and will easily handle lots of
- * small packets.

- *				Theory of Operation
- *
- * The MPC8xx CPM performs the Ethernet processing on SCC1.  It can use
- * an aribtrary number of buffers on byte boundaries, but must have at
- * least two receive buffers to prevent constant overrun conditions.
- *
- * The buffer descriptors are allocated from the CPM dual port memory
- * with the data buffers allocated from host memory, just like all other
- * serial communication protocols.  The host memory buffers are allocated
- * from the free page pool, and then divided into smaller receive and
- * transmit buffers.  The size of the buffers should be a power of two,
- * since that nicely divides the page.  This creates a ring buffer
- * structure similar to the LANCE and other controllers.
- *
- * Like the LANCE driver:
- * The driver runs as two independent, single-threaded flows of control.  One
- * is the send-packet routine, which enforces single-threaded use by the
- * cep->tx_busy flag.  The other thread is the interrupt handler, which is
- * single threaded by the hardware and other software.
- *
- * The send packet thread has partial control over the Tx ring and the
- * 'cep->tx_busy' flag.  It sets the tx_busy flag whenever it's queuing a Tx
- * packet. If the next queue slot is empty, it clears the tx_busy flag when
- * finished otherwise it sets the 'lp->tx_full' flag.
- *
- * The MBX has a control register external to the MPC8xx that has some
- * control of the Ethernet interface.  Information is in the manual for
- * your board.
- *
- * The RPX boards have an external control/status register.  Consult the
- * programming documents for details unique to your board.
- *
- * For the TQM8xx(L) modules, there is no control register interface.
- * All functions are directly controlled using I/O pins.  See <asm/cpm1.h>.

- * Fast Ethernet Controller (FEC) driver for Motorola MPC8xx.
- * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
- *
- * This version of the driver is specific to the FADS implementation,
- * since the board contains control registers external to the processor
- * for the control of the LevelOne LXT970 transceiver.  The MPC860T manual
- * describes connections using the internal parallel port I/O, which
- * is basically all of Port D.
- *
- * Includes support for the following PHYs: QS6612, LXT970, LXT971/2.
- *
- * Right now, I am very wasteful with the buffers.  I allocate memory
- * pages and then divide them into 2K frame buffers.  This way I know I
- * have buffers large enough to hold one frame within one buffer descriptor.
- * Once I get this working, I will use 64 or 128 byte CPM buffers, which
- * will be much more memory efficient and will easily handle lots of
- * small packets.
- *
- * Much better multiple PHY support by Magnus Damm.
- * Copyright (c) 2000 Ericsson Radio Systems AB.
- *
- * Make use of MII for PHY control configurable.
- * Some fixes.

-	help
-	  There are four types of PowerPC chips supported.  The more common
-	  types (601, 603, 604, 740, 750, 7400), the older Freescale
-	  (formerly Motorola) embedded versions (821, 823, 850, 855, 860,
-	  52xx, 82xx), the IBM embedded versions (403 and 405) and
-	  the Book E embedded processors from IBM (44x) and Freescale (85xx).
-	  For support for 64-bit processors, set ARCH=powerpc.
-	  Unless you are building a kernel for one of the embedded processor
-	  systems, choose 6xx.
-	  Also note that because the 52xx, 82xx family have a 603e
-	  core, specific support for that chipset is asked later on.

-
-config ALTIVEC
-	bool "AltiVec Support"
-	depends on 6xx
-	depends on !8260
-	---help---
-	  This option enables kernel support for the Altivec extensions to the
-	  PowerPC processor. The kernel currently supports saving and restoring
-	  altivec registers, and turning on the 'altivec enable' bit so user
-	  processes can execute altivec instructions.
-
-	  This option is only usefully if you have a processor that supports
-	  altivec (G4, otherwise known as 74xx series), but does not have
-	  any affect on a non-altivec cpu (it does, however add code to the
-	  kernel).
-
-	  If in doubt, say Y here.
-
-config TAU
-	bool "Thermal Management Support"
-	depends on 6xx && !8260
-	help
-	  G3 and G4 processors have an on-chip temperature sensor called the
-	  'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
-	  temperature within 2-4 degrees Celsius. This option shows the current
-	  on-die temperature in /proc/cpuinfo if the cpu supports it.
-
-	  Unfortunately, on some chip revisions, this sensor is very inaccurate
-	  and in some cases, does not work at all, so don't assume the cpu
-	  temp is actually what /proc/cpuinfo says it is.
-
-config TAU_INT
-	bool "Interrupt driven TAU driver (DANGEROUS)"
-	depends on TAU
-	---help---
-	  The TAU supports an interrupt driven mode which causes an interrupt
-	  whenever the temperature goes out of range. This is the fastest way
-	  to get notified the temp has exceeded a range. With this option off,
-	  a timer is used to re-check the temperature periodically.
-
-	  However, on some cpus it appears that the TAU interrupt hardware
-	  is buggy and can cause a situation which would lead unexplained hard
-	  lockups.
-
-	  Unless you are extending the TAU driver, or enjoy kernel/hardware
-	  debugging, leave this option off.
-
-config TAU_AVERAGE
-	bool "Average high and low temp"
-	depends on TAU
-	---help---
-	  The TAU hardware can compare the temperature to an upper and lower
-	  bound.  The default behavior is to show both the upper and lower
-	  bound in /proc/cpuinfo. If the range is large, the temperature is
-	  either changing a lot, or the TAU hardware is broken (likely on some
-	  G4's). If the range is small (around 4 degrees), the temperature is
-	  relatively stable.  If you say Y here, a single temperature value,
-	  halfway between the upper and lower bounds, will be reported in
-	  /proc/cpuinfo.
-
-	  If in doubt, say N here.
-
-config MATH_EMULATION
-	bool "Math emulation"
-	depends on 4xx || 8xx
-	---help---
-	  Some PowerPC chips designed for embedded applications do not have
-	  a floating-point unit and therefore do not implement the
-	  floating-point instructions in the PowerPC instruction set.  If you
-	  say Y here, the kernel will include code to emulate a floating-point
-	  unit, which will allow programs that use floating-point
-	  instructions to run.
-
-	  If you have an Apple machine or an IBM RS/6000 or pSeries machine,
-	  or any machine with a 6xx, 7xx or 7xxx series processor, say N
-	  here.  Saying Y here will not hurt performance (on any machine) but
-	  will increase the size of the kernel.
-
-config KEXEC
-	bool "kexec system call (EXPERIMENTAL)"
-	depends on EXPERIMENTAL
-	help
-	  kexec is a system call that implements the ability to shutdown your
-	  current kernel, and to start another kernel.  It is like a reboot
-	  but it is independent of the system firmware.   And like a reboot
-	  you can start any kernel with it, not just Linux.
-
-	  The name comes from the similarity to the exec system call.
-
-	  It is an ongoing process to be certain the hardware in a machine
-	  is properly shutdown, so do not be surprised if this code does not
-	  initially work for you.  It may help to enable device hotplugging
-	  support.  As of this writing the exact hardware interface is
-	  strongly in flux, so no good recommendation can be made.
-
-	  In the GameCube implementation, kexec allows you to load and
-	  run DOL files, including kernel and homebrew DOLs.

-config PPC601_SYNC_FIX
-	bool "Workarounds for PPC601 bugs"
-	depends on 6xx && PPC_PREP
-	help
-	  Some versions of the PPC601 (the first PowerPC chip) have bugs which
-	  mean that extra synchronization instructions are required near
-	  certain instructions, typically those that make major changes to the
-	  CPU state.  These extra instructions reduce performance slightly.
-	  If you say N here, these extra instructions will not be included,
-	  resulting in a kernel which will run faster but may not run at all
-	  on some systems with the PPC601 chip.
-
-	  If in doubt, say Y here.

-# This is far from simple, but I couldn't think of a good name.  This is
-# for making the 'zImage' or 'zImage.initrd' on a number of targets.
-#
-# Author: Tom Rini <trini@mvista.com>
-#
-# Notes:
-# (1) For machines that do not want to use the ELF image directly (including
-# stripping just the ELF header off), they must set the variables
-# zimage-$(CONFIG_MACHINE) and zimagerd-$(CONFIG_MACHINE) to the target
-# that produces the desired image and they must set end-$(CONFIG_MACHINE)
-# to what will be suffixed to the image filename.
-# (2) Regardless of (1), to have the resulting image be something other
-# than 'zImage.elf', set end-$(CONFIG_MACHINE) to be the suffix used for
-# the zImage, znetboot, and znetbootrd targets.
-# (3) For machine targets which use the mktree program, you can optionally
-# set entrypoint-$(CONFIG_MACHINE) to the location which the image should be
-# loaded at.  The optimal setting for entrypoint-$(CONFIG_MACHINE) is the link
-# address.
-# (4) It is advisable to pass in the memory size using BI_MEMSIZE and
-# get_mem_size(), which is memory controller dependent.  Add in the correct
-# XXX_memory.o file for this to work, as well as editing the
-# misc-$(CONFIG_MACHINE) variable.

- * When reading the configuration space, if something does not respond
- * the bus times out and we get a machine check interrupt.  So, the
- * good ol' exception tables come to mind to trap it and return some
- * value.
- *
- * On an error we just return a -1, since that is what the caller wants
- * returned if nothing is present.  I copied this from __get_user_asm,
- * with the only difference of returning -1 instead of EFAULT.
- * There is an associated hack in the machine check trap code.
- *
- * The QSPAN is also a big endian device, that is it makes the PCI
- * look big endian to us.  This presents a problem for the Linux PCI
- * functions, which assume little endian.  For example, we see the
- * first 32-bit word like this:
- *	------------------------
- *	| Device ID | Vendor ID |
- *	------------------------
- * If we read/write as a double word, that's OK.  But in our world,
- * when read as a word, device ID is at location 0, not location 2 as
- * the little endian PCI would believe.  We have to switch bits in
- * the PCI addresses given to us to get the data to/from the correct
- * byte lanes.
- *
- * The QSPAN only supports 4 bits of "slot" in the dev_fn instead of 5.
- * It always forces the MS bit to zero.  Therefore, dev_fn values
- * greater than 128 are returned as "no device found" errors.
- *
- * The QSPAN can only perform long word (32-bit) configuration cycles.
- * The "offset" must have the two LS bits set to zero.  Read operations
- * require we read the entire word and then sort out what should be
- * returned.  Write operations other than long word require that we
- * read the long word, update the proper word or byte, then write the
- * entire long word back.
- *
- * PCI Bridge hack.  We assume (correctly) that bus 0 is the primary
- * PCI bus from the QSPAN.  If we are called with a bus number other
- * than zero, we create a Type 1 configuration access that a downstream
- * PCI bridge will interpret.

-/* MPC8xx
- * This port was done on an MBX board with an 860.  Right now I only
- * support an ELF compressed (zImage) boot from EPPC-Bug because the
- * code there loads up some registers before calling us:
- *   r3: ptr to board info data
- *   r4: initrd_start or if no initrd then 0
- *   r5: initrd_end - unused if r4 is 0
- *   r6: Start of command line string
- *   r7: End of command line string
- *
- * I decided to use conditional compilation instead of checking PVR and
- * adding more processor specific branches around code I don't need.
- * Since this is an embedded processor, I also appreciate any memory
- * savings I can get.
- *
- * The MPC8xx does not have any BATs, but it supports large page sizes.
- * We first initialize the MMU to support 8M byte pages, then load one
- * entry into each of the instruction and data TLBs to map the first
- * 8M 1:1.  I also mapped an additional I/O space 1:1 so we can get to
- * the "internal" processor registers before MMU_init is called.
- *
- * The TLB code currently contains a major hack.  Since I use the condition
- * code register, I have to save and restore it.  I am out of registers, so
- * I just store it in memory location 0 (the TLB handlers are not reentrant).
- * To avoid making any decisions, I need to use the "segment" valid bit
- * in the first level table, but that would require many changes to the
- * Linux page directory/table functions that I don't want to do right now.
- *
- * I used to use SPRG2 for a temporary register in the TLB handler, but it
- * has since been put to other uses.  I now use a hack to save a register
- * and the CCR at memory location 0.....Someday I'll fix this.....

- *  keep as much of the original configuration as possible, but tweak it
- *  when it's found to be wrong.
- *
- *  Known BIOS problems we have to work around:
- *	- I/O or memory regions not configured
- *	- regions configured, but not enabled in the command register
- *	- bogus I/O addresses above 64K used
- *	- expansion ROMs left enabled (this may sound harmless, but given
- *	  the fact the PCI specs explicitly allow address decoders to be
- *	  shared between expansion ROMs and other resource regions, it's
- *	  at least dangerous)
- *
- *  Our solution:
- *	(1) Allocate resources for all buses behind PCI-to-PCI bridges.
- *	    This gives us fixed barriers on where we can allocate.
- *	(2) Allocate resources for all enabled devices.  If there is
- *	    a collision, just mark the resource as unallocated. Also
- *	    disable expansion ROMs during this step.
- *	(3) Try to allocate resources for disabled devices.  If the
- *	    resources were assigned correctly, everything goes well,
- *	    if they weren't, they won't disturb allocation of other
- *	    resources.
- *	(4) Assign new addresses to resources which were either
- *	    not configured at all or misconfigured.  If explicitly
- *	    requested by the user, configure expansion ROM address
- *	    as well.

- *  Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
- *
- *  Module name: remcom.c $
- *  Revision: 1.34 $
- *  Date: 91/03/09 12:29:49 $
- *  Contributor:     Lake Stevens Instrument Division$
- *
- *  Description:     low level support for gdb debugger. $
- *
- *  Considerations:  only works on target hardware $
- *
- *  Written by:      Glenn Engel $
- *  ModuleState:     Experimental $
- *
- *  NOTES:           See Below $
- *
- *  Modified for SPARC by Stu Grossman, Cygnus Support.
- *
- *  This code has been extensively tested on the Fujitsu SPARClite demo board.
- *
- *  To enable debugger support, two things need to happen.  One, a
- *  call to set_debug_traps() is necessary in order to allow any breakpoints
- *  or error conditions to be properly intercepted and reported to gdb.
- *  Two, a breakpoint needs to be generated to begin communication.  This
- *  is most easily accomplished by a call to breakpoint().  Breakpoint()
- *  simulates a breakpoint by executing a trap #1.
- *
- *************
- *
- *    The following gdb commands are supported:
- *
- * command          function		          Return value
- *
- *    g             return the value of the CPU registers  hex data or ENN
- *    G             set the value of the CPU registers     OK or ENN
- *    qOffsets      Get section offsets.  Reply is Text=xxx;Data=yyy;Bss=zzz
- *
- *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
- *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
- *
- *    c             Resume at current address              SNN   ( signal NN)
- *    cAA..AA       Continue at address AA..AA             SNN
- *
- *    s             Step one instruction                   SNN
- *    sAA..AA       Step one instruction from AA..AA       SNN
- *
- *    k             kill
- *
- *    ?             What was the last sigval ?             SNN   (signal NN)
- *
- *    bBB..BB	    Set baud rate to BB..BB		   OK or BNN, then sets
- *							   baud rate
- *
- * All commands and responses are sent with a packet which includes a
- * checksum.  A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum>    :: <two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer.  '-' indicates a failed transfer.
- *
- * Example:
- *
- * Host:                  Reply:
- * $m0,10#2a               +$00010203040506070809101112131415#42

- * Common time routines among all ppc machines.

- * Written by Cort Dougan (cort@cs.nmt.edu) to merge
- * Paul Mackerras' version and mine for PReP and Pmac.
- * MPC8xx/MBX changes by Dan Malek (dmalek@jlc.net).
- *
- * First round of bugfixes by Gabriel Paubert (paubert@iram.es)
- * to make clock more stable (2.4.0-test5). The only thing
- * that this code assumes is that the timebases have been synchronized
- * by firmware on SMP and are never stopped (never do sleep
- * on SMP then, nap and doze are OK).
- *
- * TODO (not necessarily in this file):
- * - improve precision and reproducibility of timebase frequency
- * measurement at boot time.
- * - get rid of xtime_lock for gettimeofday (generic kernel problem
- * to be implemented on all architectures for SMP scalability and
- * eventually implementing gettimeofday without entering the kernel).
- * - put all time/clock related variables in a single structure
- * to minimize number of cache lines touched by gettimeofday()
- * - for astronomical applications: add a new function to get
- * non ambiguous timestamps even around leap seconds. This needs
- * a new timestamp format and a good name.
- *
- *
- * The following comment is partially obsolete (at least the long wait
- * is no more a valid reason):
- * Since the MPC8xx has a programmable interrupt timer, I decided to
- * use that rather than the decrementer.  Two reasons: 1.) the clock
- * frequency is low, causing 2.) a long wait in the timer interrupt
- *		while ((d = get_dec()) == dval)
- * loop.  The MPC8xx can be driven from a variety of input clocks,
- * so a number of assumptions have been made here because the kernel
- * parameter HZ is a constant.  We assume (correctly, today :-) that
- * the MPC8xx on the MBX board is driven from a 32.768 kHz crystal.
- * This is then divided by 4, providing a 8192 Hz clock into the PIT.
- * Since it is not possible to get a nice 100 Hz clock out of this, without
- * creating a software PLL, I have set HZ to 128.  -- Dan

- * This file adds support for the Motorola SPS Sandpoint Test Platform.
- * These boards have a PPMC slot for the processor so any combination
- * of cpu and host bridge can be attached.  This port is for an 8240 PPMC
- * module from Motorola SPS and other closely related cpu/host bridge
- * combinations (e.g., 750/755/7400 with MPC107 host bridge).
- * The sandpoint itself has a Windbond 83c553 (PCI-ISA bridge, 2 DMA ctlrs, 2
- * cascaded 8259 interrupt ctlrs, 8254 Timer/Counter, and an IDE ctlr), a
- * National 87308 (RTC, 2 UARTs, Keyboard & mouse ctlrs, and a floppy ctlr),
- * and 4 PCI slots (only 2 of which are usable; the other 2 are keyed for 3.3V
- * but are really 5V).
- *
- * The firmware on the sandpoint is called DINK (not my acronym :).  This port
- * depends on DINK to do some basic initialization (e.g., initialize the memory
- * ctlr) and to ensure that the processor is using MAP B (CHRP map).
- *
- * The switch settings for the Sandpoint board MUST be as follows:
- * 	S3: down
- * 	S4: up
- * 	S5: up
- * 	S6: down
- *
- * 'down' is in the direction from the PCI slots towards the PPMC slot;
- * 'up' is in the direction from the PPMC slot towards the PCI slots.
- * Be careful, the way the sandpoint board is installed in XT chasses will
- * make the directions reversed.
- *
- * Since Motorola listened to our suggestions for improvement, we now have
- * the Sandpoint X3 board.  All of the PCI slots are available, it uses
- * the serial interrupt interface (just a hardware thing we need to
- * configure properly).
- *
- * Use the default X3 switch settings.  The interrupts are then:
- *		EPIC	Source
- *		  0	SIOINT 		(8259, active low)
- *		  1	PCI #1
- *		  2	PCI #2
- *		  3	PCI #3
- *		  4	PCI #4
- *		  7	Winbond INTC	(IDE interrupt)
- *		  8	Winbond INTD	(IDE interrupt)
- *
- *
- * Motorola has finally released a version of DINK32 that correctly
- * (seemingly) initializes the memory controller correctly, regardless
- * of the amount of memory in the system.  Once a method of determining
- * what version of DINK initializes the system for us, if applicable, is
- * found, we can hopefully stop hardcoding 32MB of RAM.

- *  OCP (On Chip Peripheral) is a software emulated "bus" with a
- *  pseudo discovery method for dumb peripherals. Usually these type
- *  of peripherals are found on embedded SoC (System On a Chip)
- *  processors or highly integrated system controllers that have
- *  a host bridge and many peripherals.  Common examples where
- *  this is already used include the PPC4xx, MPC52xx,
- *  and MV64xxx parts.
- *
- *  This subsystem creates a standard OCP bus type within the
- *  device model.  The devices on the OCP bus are seeded by an
- *  an initial OCP device array created by the arch-specific
- *  Device entries can be added/removed/modified through OCP
- *  helper functions to accommodate system and  board-specific
- *  parameters commonly found in embedded systems. OCP also
- *  provides a standard method for devices to describe extended
- *  attributes about themselves to the system.  A standard access
- *  method allows OCP drivers to obtain the information, both
- *  SoC-specific and system/board-specific, needed for operation.

- *   Create a scatter/gather list handle.  This is simply a structure which
- *   describes a scatter/gather list.
- *
- *   A handle is returned in "handle" which the driver should save in order to
- *   be able to access this list later.  A chunk of memory will be allocated
- *   to be used by the API for internal management purposes, including managing
- *   the sg list and allocating memory for the sgl descriptors.  One page should
- *   be more than enough for that purpose.  Perhaps it's a bit wasteful to use
- *   a whole page for a single sg list, but most likely there will be only one
- *   sg list per channel.
- *
- *   Interrupt notes:
- *   Each sgl descriptor has a copy of the DMA control word which the DMA engine
- *   loads in the control register.  The control word has a "global" interrupt
- *   enable bit for that channel. Interrupts are further qualified by a few bits
- *   in the sgl descriptor count register.  In order to setup an sgl, we have to
- *   know ahead of time whether or not interrupts will be enabled at the completion
- *   of the transfers.  Thus, enable_dma_interrupt()/disable_dma_interrupt() MUST
- *   be called before calling alloc_dma_handle().  If the interrupt mode will never
- *   change after powerup, then enable_dma_interrupt()/disable_dma_interrupt()
- *   do not have to be called -- interrupts will be enabled or disabled based
- *   on how the channel was configured after powerup by the hw_init_dma_channel()
- *   function.  Each sgl descriptor will be setup to interrupt if an error occurs;
- *   however, only the last descriptor will be setup to interrupt. Thus, an
- *   interrupt will occur (if interrupts are enabled) only after the complete
- *   sgl transfer is done.

- * This blows......
- * When reading the configuration space, if something does not respond
- * the bus times out and we get a machine check interrupt.  So, the
- * good ol' exception tables come to mind to trap it and return some
- * value.
- *
- * On an error we just return a -1, since that is what the caller wants
- * returned if nothing is present.  I copied this from __get_user_asm,
- * with the only difference of returning -1 instead of EFAULT.
- * There is an associated hack in the machine check trap code.
- *
- * The QSPAN is also a big endian device, that is it makes the PCI
- * look big endian to us.  This presents a problem for the Linux PCI
- * functions, which assume little endian.  For example, we see the
- * first 32-bit word like this:
- *	------------------------
- *	| Device ID | Vendor ID |
- *	------------------------
- * If we read/write as a double word, that's OK.  But in our world,
- * when read as a word, device ID is at location 0, not location 2 as
- * the little endian PCI would believe.  We have to switch bits in
- * the PCI addresses given to us to get the data to/from the correct
- * byte lanes.
- *
- * The QSPAN only supports 4 bits of "slot" in the dev_fn instead of 5.
- * It always forces the MS bit to zero.  Therefore, dev_fn values
- * greater than 128 are returned as "no device found" errors.
- *
- * The QSPAN can only perform long word (32-bit) configuration cycles.
- * The "offset" must have the two LS bits set to zero.  Read operations
- * require we read the entire word and then sort out what should be
- * returned.  Write operations other than long word require that we
- * read the long word, update the proper word or byte, then write the
- * entire long word back.
- *
- * PCI Bridge hack.  We assume (correctly) that bus 0 is the primary
- * PCI bus from the QSPAN.  If we are called with a bus number other
- * than zero, we create a Type 1 configuration access that a downstream
- * PCI bridge will interpret.

- * Depending on the hardware on your board and your board design, the

- * address/data registers.  If your board uses the direct method, set
- * 'nvram_data' to the base address of your nvram and leave 'nvram_as0' and
- * 'nvram_as1' NULL.  If your board uses address/data regs to access nvram,
- * set 'nvram_as0' to the address of the lower byte, set 'nvram_as1' to the
- * address of the upper byte (leave NULL if using mc146818), and set
- * 'nvram_data' to the address of the 8-bit data register.
- *
- * In order to break the assumption that the RTC and NVRAM are accessed by
- * the same mechanism, you need to explicitly set 'ppc_md.rtc_read_val' and
- * 'ppc_md.rtc_write_val', otherwise the values of 'ppc_md.rtc_read_val'
- * and 'ppc_md.rtc_write_val' will be used.
- *
- * Note: Even though the documentation for the various RTC chips say that it
- * 	 take up to a second before it starts updating once the 'R' bit is
- * 	 cleared, they always seem to update even though we bang on it many
- * 	 times a second.  This is true, except for the Dallas Semi 1746/1747
- * 	 (possibly others).  Those chips seem to have a real problem whenever
- * 	 we set the 'R' bit before reading them, they basically stop counting.

-/* ANSI and traditional C compatibility macros
-
-   ANSI C is assumed if __STDC__ is #defined.
-
-   Macro	ANSI C definition	Traditional C definition
-   -----	---- - ----------	----------- - ----------
-   PTR		`void *'		`char *'
-   LONG_DOUBLE	`long double'		`double'
-   VOLATILE	`volatile'		`'
-   SIGNED	`signed'		`'
-   PTRCONST	`void *const'		`char *'
-   ANSI_PROTOTYPES  1			not defined
-
-   CONST is also defined, but is obsolete.  Just use const.
-
-   DEFUN (name, arglist, args)
-
-	Defines function NAME.
-
-	ARGLIST lists the arguments, separated by commas and enclosed in
-	parentheses.  ARGLIST becomes the argument list in traditional C.
-
-	ARGS list the arguments with their types.  It becomes a prototype in
-	ANSI C, and the type declarations in traditional C.  Arguments should
-	be separated with `AND'.  For functions with a variable number of
-	arguments, the last thing listed should be `DOTS'.
-
-   DEFUN_VOID (name)
-
-	Defines a function NAME, which takes no arguments.
-
-   obsolete --     EXFUN (name, (prototype))	-- obsolete.
-
-	Replaced by PARAMS.  Do not use; will disappear someday soon.
-	Was used in external function declarations.
-	In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in
-	parentheses).  In traditional C it is `NAME()'.
-	For a function that takes no arguments, PROTOTYPE should be `(void)'.
-
-    PARAMS ((args))
-
-	We could use the EXFUN macro to handle prototype declarations, but
-	the name is misleading and the result is ugly.  So we just define a
-	simple macro to handle the parameter lists, as in:
-
-	      static int foo PARAMS ((int, char));
-
-	This produces:  `static int foo();' or `static int foo (int, char);'
-
-	EXFUN would have done it like this:
-
-	      static int EXFUN (foo, (int, char));
-
-	but the function is not external...and it's hard to visually parse
-	the function name out of the mess.   EXFUN should be considered
-	obsolete; new code should be written to use PARAMS.
-
-    For example:
-	extern int printf PARAMS ((CONST char *format DOTS));
-	int DEFUN(fprintf, (stream, format),
-		  FILE *stream AND CONST char *format DOTS) { ... }
-	void DEFUN_VOID(abort) { ... }

- * @vendor:    Vendor code. It is _STRONGLY_ discouraged to use

- *             though I kept that possibility open, you should
- *             really define different function codes for different
- *             device types
- * @function:  This is the function code for this device.
- * @index:     This index is used for mapping the Nth function of a
- *             given core. This is typically used for cross-driver
- *             matching, like looking for a given MAL or ZMII from
- *             an EMAC or for getting to the proper set of DCRs.
- *             Indices are no longer magically calculated based on
- *             structure ordering, they have to be actually coded
- *             into the ocp_def to avoid any possible confusion
- *             I _STRONGLY_ (again ? wow !) encourage anybody relying
- *             on index mapping to encode the "target" index in an
- *             associated structure pointed to by "additions", see
- *             how it's done for the EMAC driver.
- * @paddr:     Device physical address (may not mean anything...)
- * @irq:       Interrupt line for this device (TODO: think about making
- *             an array with this)
- * @pm:        Currently, contains the bitmask in CPMFR DCR for the device
- * @additions: Optionally points to a function specific structure
- *             providing additional informations for a given device
- *             instance. It's currently used by the EMAC driver for MAL
- *             channel & ZMII port mapping among others.
- * @show:      Optionally points to a function specific structure
- *             providing a sysfs show routine for additions fields.

- *
- * There are some constrains and options, to decide mapping software bits
- * into TLB entry.
- *
- *   - PRESENT *must* be in the bottom three bits because swap cache
- *     entries use the top 29 bits for TLB2.
- *
- *   - FILE *must* be in the bottom three bits because swap cache
- *     entries use the top 29 bits for TLB2.
- *
- *   - CACHE COHERENT bit (M) has no effect on PPC440 core, because it
- *     doesn't support SMP. So we can use this as software bit, like
- *     DIRTY.
- *
- * With the PPC 44x Linux implementation, the 0-11th LSBs of the PTE are used
- * for memory protection related functions (see PTE structure in
- * include/asm-ppc/mmu.h).  The _PAGE_XXX definitions in this file map to the
- * above bits.  Note that the bit values are CPU specific, not architecture
- * specific.
- *
- * The kernel PTE entry holds an arch-dependent swp_entry structure under
- * certain situations. In other words, in such situations some portion of
- * the PTE bits are used as a swp_entry. In the PPC implementation, the
- * 3-24th LSB are shared with swp_entry, however the 0-2nd three LSB still
- * hold protection values. That means the three protection bits are
- * reserved for both PTE and SWAP entry at the most significant three
- * LSBs.
- *
- * There are three protection bits available for SWAP entry:
- *	_PAGE_PRESENT
- *	_PAGE_FILE
- *	_PAGE_HASHPTE (if HW has)

Subject: [PATCH 119/794] powerpc/85xx: correct vendor prefix in DTS files for
 TQM85xx modules

Like for the TQM5200, the vendor prefix "tqc," is now used for all
TQM85xx modules from TQ-Components GmbH (http://www.tqc.de) in the
corresponding DTS files.

From 02b8a3d1eb2ae6353cfbce627ded22e299cf1989 Mon Sep 17 00:00:00 2001
From: Wolfgang Grandegger <wg@grandegger.com>
Date: Fri, 6 Jun 2008 13:50:05 +0200
Subject: [PATCH 121/794] powerpc/85xx: support for the TQM8548 module using
 the big Flash

Some TQM85xx boards could be equipped with up to 1 GiB (NOR) flash
memory and therefore a modified memory map is required and setup by
the board loader. This patch adds an appropriate DTS file.

Subject: [PATCH 123/794] powerpc/sysdev: implement FSL GTM support

GTM stands for General-purpose Timers Module and able to generate
timer{1,2,3,4} interrupts. These timers are used by the drivers that
need time precise interrupts (like for USB transactions scheduling for
the Freescale USB Host controller as found in some QE and CPM chips),
or these timers could be used as wakeup events from the CPU deep-sleep
mode.

Things unimplemented:
1. Cascaded (32 bit) timers (1-2, 3-4).
   This is straightforward to implement when needed, two timers should
   be marked as "requested" and configured as appropriate.
2. Super-cascaded (64 bit) timers (1-2-3-4).
   This is also straightforward to implement when needed, all timers
   should be marked as "requested" and configured as appropriate.

Subject: [PATCH 124/794] powerpc/QE: add support for QE USB clocks routing

This patch adds a function to the qe_lib to setup QE USB clocks routing.
To setup clocks safely, cmxgcr register needs locking, so I just reused
ucc_lock since it was used only to protect cmxgcr.

The idea behind placing clocks routing functions into the qe_lib is that
later we'll hopefully switch to the generic Linux Clock API, thus, for
example, FHCI driver may be used for QE and CPM chips without nasty #ifdefs.

This patch also fixes QE_USB_RESTART_TX command definition in the qe.h.

  could use the prefixed version with GPIO LIB API;
- rename struct port_regs to qe_pio_regs, and place it into qe.h;
- rename #define NUM_OF_PINS to QE_PIO_PINS, and place it into qe.h.

+   Note that "par_io" nodes are obsolete, and should not be used for
+   the new device trees. Instead, each Par I/O bank should be represented
+   via its own gpio-controller node:
+
+   Required properties:
+   - #gpio-cells : should be "2".
+   - compatible : should be "fsl,<chip>-qe-pario-bank",
+     "fsl,mpc8323-qe-pario-bank".
+   - reg : offset to the register set and its length.
+   - gpio-controller : node to identify gpio controllers.
+
+   Example:
+	qe_pio_a: gpio-controller@1400 {
+		#gpio-cells = <2>;
+		compatible = "fsl,mpc8360-qe-pario-bank",
+			     "fsl,mpc8323-qe-pario-bank";

Subject: [PATCH 127/794] powerpc/83xx: new board support: MPC8360E-RDK

This is patch adds board file, device tree, and defconfig for the new
board, made by Freescale Semiconductor Inc. and Logic Product Development.

Currently supported:
1. UEC{1,2,7,4};
2. I2C;
3. SPI;
4. NS16550 serial;
5. PCI and miniPCI;
6. Intel NOR StrataFlash X16 64Mbit PC28F640P30T85;
7. Graphics controller, Fujitsu MB86277.

Not supported in this patch:
1. StMICRO NAND512W3A2BN6E, 512 Mbit (supported with FSL UPM NAND driver);
2. FHCI USB (supported with FHCI driver).
3. QE Serial UCCs (tested to not work with ucc_uart driver, reason
   unknown, yet);
4. ADC AD7843 (tested to work, but support via device tree depends on
   major SPI rework, GPIO API, etc);

Subject: [PATCH 128/794] powerpc/QE: switch to the cpm_muram implementation

This is very trivial patch. We're transitioning to the cpm_muram_*
calls. That's it.

Less trivial changes:
- BD_SC_* defines were defined in the cpm.h and qe.h, so to avoid redefines
  we remove BD_SC from the qe.h and use cpm.h along with cpm_muram_*
  prototypes;
- qe_muram_dump was unused and thus removed;
- added some code to the cpm_common.c to support legacy QE bindings
  (data-only node name).
- For convenience, define qe_* calls to cpm_*. So drivers need not to be
  changed.

Subject: [PATCH 132/794] powerpc/4xx: Fix resource issue in warp-nand.c

The "ndfc-chip" device doesn't need any resources. All resources
are handled by the "ndfc-nand" device. Registering the same memory
resource twice causes "cat /proc/iomem" to go into an infinite loop
displaying NDFC memory addresses.

Subject: [PATCH 133/794] powerpc/4xx: PCIe driver now detects if a port is
 disabled via the dev-tree

This patch add a check to the PPC4xx PCIe driver to detect if the port
is disabled via the device-tree. This is needed for the AMCC Canyonlands
board which has an option to either select 2 PCIe ports or 1 PCIe port
and one SATA port. The SATA port and the 1st PCIe port pins are multiplexed
so we can't start both drivers.

Subject: [PATCH 138/794] cpu topology: always define CPU topology information

This can result in an empty topology directory in sysfs, and requires
in-kernel users to protect all uses with #ifdef - see
<http://marc.info/?l=linux-netdev&m=120639033904472&w=2>.

The documentation of CPU topology specifies what the defaults should be if
only partial information is available from the hardware.  So we can
provide these defaults as a fallback.

This patch:

- Adds default definitions of the 4 topology macros to <linux/topology.h>
- Changes drivers/base/topology.c to use the topology macros unconditionally
  and to cope with definitions that aren't lvalues
- Updates documentation accordingly

[ From: Andrew Morton <akpm@linux-foundation.org>
  - fold now-duplicated code
  - fix layout

Subject: [PATCH 141/794] Revert "prohibit rcutorture from being compiled into
 the kernel"

This reverts commit 9aaffc898ff4a3df18c5fc4b9e0fa47e779ad726.

That commit was a very bad idea. RCU_TORTURE found many boot timing
bugs and other sorts of bugs in the past, so excluding it from
boot images is very silly.

The option already depends on DEBUG_KERNEL and is disabled by default.
Even when it runs, the test threads are reniced. If it annoys people
we could add a runtime sysctl.

Subject: [PATCH 144/794] powerpc/4xx: Workaround for PPC440EPx/GRx PCI_28
 Errata

The 440EPx/GRx chips don't support PCI MRM commands.  Drivers determine this
by looking for a zero value in the PCI cache line size register.  However,
some drivers write to this register upon initialization.  This can cause
MRMs to be used on these chips, which may cause deadlocks on PLB4.

The workaround implemented here introduces a new indirect_type flag, called
PPC_INDIRECT_TYPE_BROKEN_MRM.  This is set in the pci_controller structure in
the pci fixup function for 4xx PCI bridges by determining if the bridge is
compatible with 440EPx/GRx.  The flag is checked in the indirect_write_config
function, and forces any writes to the PCI_CACHE_LINE_SIZE register to be
zero, which will disable MRMs for these chips.

A similar workaround has been tested by AMCC on various PCI cards, such as
the Silicon Image ATA card and Intel E1000 GIGE card.  Hangs were seen with
the Silicon Image card, and MRMs were seen on the bus with a PCI analyzer.
With the workaround in place, the card functioned properly and only Memory
Reads were seen on the bus with the analyzer.

Subject: [PATCH 146/794] rcu: make rcutorture more vicious: add stutter
 feature

This patch takes a step towards making rcutorture more brutal by allowing
the test to be automatically periodically paused, with the default being
to run the test for five seconds then pause for five seconds and repeat.
This behavior can be controlled using a new "stutter" module parameter, so
that "stutter=0" gives the old default behavior of running continuously.

Starting and stopping rcutorture more heavily stresses RCU's interaction
with the scheduler, as well as exercising more paths through the
grace-period detection code.

Note that the default to "shuffle_interval" has also been adjusted from
5 seconds to 3 seconds to provide varying overlap with the "stutter"
interval.

I am still unable to provoke the failures that Alexey has been seeing,
even with this patch, but will be doing a few additional things to beef
up rcutorture.

Subject: [PATCH 148/794] rcu: make rcutorture more vicious: reinstate
 boot-time testing

This patch re-institutes the ability to build rcutorture directly into
the Linux kernel.  The reason that this capability was removed was that
this could result in your kernel being pretty much useless, as rcutorture
would be running starting from early boot.  This problem has been avoided
by (1) making rcutorture run only three seconds of every six by default,
(2) adding a CONFIG_RCU_TORTURE_TEST_RUNNABLE that permits rcutorture
to be quiesced at boot time, and (3) adding a sysctl in /proc named
/proc/sys/kernel/rcutorture_runnable that permits rcutorture to be
quiesced and unquiesced when built into the kernel.

Please note that this /proc file is -not- available when rcutorture
is built as a module.  Please also note that to get the earlier
take-no-prisoners behavior, you must use the boot command line to set
rcutorture's "stutter" parameter to zero.

The rcutorture quiescing mechanism is currently quite crude: loops
in each rcutorture process that poll a global variable once per tick.
Suggestions for improvement are welcome.  The default action will
be to reduce the polling rate to a few times per second.

+
+It is also possible to specify CONFIG_RCU_TORTURE_TEST=y, which will
+result in the tests being loaded into the base kernel.  In this case,
+the CONFIG_RCU_TORTURE_TEST_RUNNABLE config option is used to specify
+whether the RCU torture tests are to be started immediately during
+boot or whether the /proc/sys/kernel/rcutorture_runnable file is used
+to enable them.  This /proc file can be used to repeatedly pause and
+restart the tests, regardless of the initial state specified by the
+CONFIG_RCU_TORTURE_TEST_RUNNABLE config option.
+
+You will normally -not- want to start the RCU torture tests during boot
+(and thus the default is CONFIG_RCU_TORTURE_TEST_RUNNABLE=n), but doing
+this can sometimes be useful in finding boot-time bugs.

Subject: [PATCH 152/794] powerpc/e500mc: flush L2 on NAP for e500mc

If we have an L2CSR register (e500mc) we need to flush the L2 before going
to nap.  We use the HW flush mechanism provided in that register.

The code reuses the CPU_FTR_604_PERF_MON bit as it is no longer used by
any code in the kernel.  Additionally we didn't reuse the exist L2CR
feature bit as this is intended for the 7xxx L2CR register and L2CSR
is part of the new Freescale "Book-E" registers.

Subject: [PATCH 154/794] cpm_uart: Remove !CONFIG_PPC_CPM_NEW_BINDING code

Now that arch/ppc is gone we always define CONFIG_PPC_CPM_NEW_BINDING so
we can remove all the code associated with !CONFIG_PPC_CPM_NEW_BINDING.

Now that arch/ppc is gone we always define CONFIG_PPC_CPM_NEW_BINDING so
we can remove all the code associated with !CONFIG_PPC_CPM_NEW_BINDING.

Subject: [PATCH 158/794] rcu: make rcutorture even more vicious: invoke RCU
 readers from irq handlers (timers)

This patch allows torturing RCU from irq handlers (timers, in this case).
A new module parameter irqreader enables such additional torturing,
and is enabled by default.  Variants of RCU that do not tolerate readers
being called from irq handlers (e.g., SRCU) ignore irqreader.

Date: Thu, 26 Jun 2008 01:57:58 -0500
Subject: [PATCH 159/794] powerpc/kprobes: Some minor fixes

* Mark __flush_icache_range as a function that can't be probed since its
  used by the kprobe code.

* Fix an issue with single stepping and async exceptions.  We need to
  ensure that we dont get an async exception (external, decrementer, etc)
  while we are attempting to single step the probe point.

  Added a check to ensure we only handle a single step if its really
  intended for the instruction in question.

 processors

This patch is based on work done by Madhvesh. R. Sulibhavi back in
March 2007.

We refactor some of the single step handling since it differs between
"classic" and "booke" powerpc cores.

Subject: [PATCH 161/794] Add generic helpers for arch IPI function calls

This adds kernel/smp.c which contains helpers for IPI function calls. In
addition to supporting the existing smp_call_function() in a more efficient
manner, it also adds a more scalable variant called smp_call_function_single()
for calling a given function on a single CPU only.

The core of this is based on the x86-64 patch from Nick Piggin, lots of
changes since then. "Alan D. Brunelle" <Alan.Brunelle@hp.com> has
contributed lots of fixes and suggestions as well. Also thanks to
Paul E. McKenney <paulmck@linux.vnet.ibm.com> for reviewing RCU usage
and getting rid of the data allocation fallback deadlock.

From 3b16cf874861436725c43ba0b68bdd799297be7c Mon Sep 17 00:00:00 2001
From: Jens Axboe <jens.axboe@oracle.com>
Date: Thu, 26 Jun 2008 11:21:54 +0200
Subject: [PATCH 162/794] x86: convert to generic helpers for IPI function
 calls

This converts x86, x86-64, and xen to use the new helpers for
smp_call_function() and friends, and adds support for
smp_call_function_single().

From b7d7a2404f80386307ccc0cde63d8d2a5e3bc85c Mon Sep 17 00:00:00 2001

Subject: [PATCH 163/794] powerpc: convert to generic helpers for IPI function
 calls

This converts ppc to use the new helpers for smp_call_function() and
friends, and adds support for smp_call_function_single().

ppc loses the timeout functionality of smp_call_function_mask() with
this change, as the generic code does not provide that.

- * Name:         smp_call_function
- *
- * Description:  This routine sends a 'CALL_FUNCTION_IPI' to all other CPUs
- *               in the system.
- *
- * Born on Date: 2002.02.05
- *
- * Arguments:    *func - The function to run. This must be fast and
- *                       non-blocking.
- *               *info - An arbitrary pointer to pass to the function.
- *               nonatomic - currently unused.
- *               wait - If true, wait (atomically) until function has
- *                      completed on other CPUs.
- *
- * Returns:      0 on success, else a negative status code. Does not return
- *               until remote CPUs are nearly ready to execute <<func>> or
- *               are or have executed.
- *
- * Cautions:     You must not call this function with disabled interrupts or
- *               from a hardware interrupt handler, you may call it from a
- *               bottom half handler.

 calls

This converts mips to use the new helpers for smp_call_function() and
friends, and adds support for smp_call_function_single(). Not tested,
but it compiles.

mips shares the same IPI for smp_call_function() and
smp_call_function_single(), since not all mips platforms have enough
available IPIs to support seperate setups.

Subject: [PATCH 169/794] parisc: convert to generic helpers for IPI function
 calls

This converts parisc to use the new helpers for smp_call_function() and
friends, and adds support for smp_call_function_single(). Tested by
Kyle, seems to work.

From 15c8b6c1aaaf1c4edd67e2f02e4d8e1bd1a51c0d Mon Sep 17 00:00:00 2001
From: Jens Axboe <jens.axboe@oracle.com>
Date: Fri, 9 May 2008 09:39:44 +0200
Subject: [PATCH 172/794] on_each_cpu(): kill unused 'retry' parameter

It's not even passed on to smp_call_function() anymore, since that
was removed. So kill it.

From 6802e3400ff4549525930ee744030c36fce9cc73 Mon Sep 17 00:00:00 2001
From: Steven Whitehouse <swhiteho@redhat.com>
Date: Wed, 21 May 2008 17:03:22 +0100
Subject: [PATCH 173/794] [GFS2] Clean up the glock core

This patch implements a number of cleanups to the core of the
GFS2 glock code. As a result a lot of code is removed. It looks
like a really big change, but actually a large part of this patch
is either removing or moving existing code.

There are some new bits too though, such as the new run_queue()
function which is considerably streamlined. Highlights of this
patch include:

 o Fixes a cluster coherency bug during SH -> EX lock conversions
 o Removes the "glmutex" code in favour of a single bit lock
 o Removes the ->go_xmote_bh() for inodes since it was duplicating
   ->go_lock()
 o We now only use the ->lm_lock() function for both locks and
   unlocks (i.e. unlock is a lock with target mode LM_ST_UNLOCKED)
 o The fast path is considerably shortly, giving performance gains
   especially with lock_nolock
 o The glock_workqueue is now used for all the callbacks from the DLM
   which allows us to simplify the lock_dlm module (see following patch)
 o The way is now open to make further changes such as eliminating the two
   threads (gfs2_glockd and gfs2_scand) in favour of a more efficient
   scheme.

This patch has undergone extensive testing with various test suites
so it should be pretty stable by now.

Subject: [PATCH 174/794] [GFS2] Fix ordering bug in lock_dlm

This looks like a lot of change, but in fact its not. Mostly its
things moving from one file to another. The change is just that
instead of queuing lock completions and callbacks from the DLM
we now pass them directly to GFS2.

This gives us a net loss of two list heads per glock (a fair
saving in memory) plus a reduction in the latency of delivering
the messages to GFS2, plus we now have one thread fewer as well.
There was a bug where callbacks and completions could be delivered
in the wrong order due to this unnecessary queuing which is fixed
by this patch.

From 048bca223739368aa5b9ce7cfb1d576c32d66cc7 Mon Sep 17 00:00:00 2001
From: Steven Whitehouse <swhiteho@redhat.com>
Date: Fri, 23 May 2008 14:46:04 +0100
Subject: [PATCH 175/794] [GFS2] No lock_nolock

This patch merges the lock_nolock module into GFS2 itself. As well as removing
some of the overhead of the module, it also means that its now impossible to
build GFS2 without a lock module (which would be a pointless thing to do
anyway).

We also plan to merge lock_dlm into GFS2 in the future, but that is a more
tricky task, and will therefore be a separate patch.

Subject: [PATCH 178/794] [GFS2] Revise readpage locking

The previous attempt to fix the locking in readpage failed due
to the use of a "try lock" which resulted in occasional high
cpu usage during testing (due to repeated tries) and also it
did not resolve all the ordering problems wrt the transaction
lock (although it did solve all the inode lock ordering problems).

This patch avoids the problem by unlocking the page and getting the
locks in the correct order. This means that we have to retest the
page to ensure that it hasn't changed when we relock the page.

This now passes the tests which were previously failing.

Subject: [PATCH 179/794] [GFS2] kernel panic mounting volume

This patch fixes Red Hat bugzilla bug 450156.

This started with a not-too-improbable mount failure because the
locking protocol was never set back to its proper "lock_dlm" after the
system was rebooted in the middle of a gfs2_fsck.  That left a
(purposely) invalid locking protocol in the superblock, which caused an
error when the file system was mounted the next time.

When there's an error mounting, vfs calls DQUOT_OFF, which calls
vfs_quota_off which calls gfs2_sync_fs.  Next, gfs2_sync_fs calls
gfs2_log_flush passing s_fs_info.  But due to the error, s_fs_info
had been previously set to NULL, and so we have the kernel oops.

My solution in this patch is to test for the NULL value before passing
it.  I tested this patch and it fixes the problem.

Subject: [PATCH 180/794] [GFS2] Remove remote lock dropping code

There are several reasons why this is undesirable:

 1. It never happens during normal operation anyway
 2. If it does happen it causes performance to be very, very poor
 3. It isn't likely to solve the original problem (memory shortage
    on remote DLM node) it was supposed to solve
 4. It uses a bunch of arbitrary constants which are unlikely to be
    correct for any particular situation and for which the tuning seems
    to be a black art.
 5. In an N node cluster, only 1/N of the dropped locked will actually
    contribute to solving the problem on average.

So all in all we are better off without it. This also makes merging
the lock_dlm module into GFS2 a bit easier.

Subject: [PATCH 182/794] [GFS2] Remove all_list from lock_dlm

I discovered that we had a list onto which every lock_dlm
lock was being put. Its only function was to discover whether
we'd got any locks left after umount. Since there was already
a counter for that purpose as well, I removed the list. The
saving is sizeof(struct list_head) per glock - well worth
having.

+                   Glock internal locking rules
+                  ------------------------------
+
+This documents the basic principles of the glock state machine
+internals. Each glock (struct gfs2_glock in fs/gfs2/incore.h)
+has two main (internal) locks:
+
+ 1. A spinlock (gl_spin) which protects the internal state such
+    as gl_state, gl_target and the list of holders (gl_holders)
+ 2. A non-blocking bit lock, GLF_LOCK, which is used to prevent other
+    threads from making calls to the DLM, etc. at the same time. If a
+    thread takes this lock, it must then call run_queue (usually via the
+    workqueue) when it releases it in order to ensure any pending tasks
+    are completed.
+
+The gl_holders list contains all the queued lock requests (not
+just the holders) associated with the glock. If there are any
+held locks, then they will be contiguous entries at the head
+of the list. Locks are granted in strictly the order that they
+are queued, except for those marked LM_FLAG_PRIORITY which are
+used only during recovery, and even then only for journal locks.
+
+There are three lock states that users of the glock layer can request,
+namely shared (SH), deferred (DF) and exclusive (EX). Those translate
+to the following DLM lock modes:
+
+Glock mode    | DLM lock mode
+------------------------------
+    UN        |    IV/NL  Unlocked (no DLM lock associated with glock) or NL
+    SH        |    PR     (Protected read)
+    DF        |    CW     (Concurrent write)
+    EX        |    EX     (Exclusive)
+
+Thus DF is basically a shared mode which is incompatible with the "normal"
+shared lock mode, SH. In GFS2 the DF mode is used exclusively for direct I/O
+operations. The glocks are basically a lock plus some routines which deal
+with cache management. The following rules apply for the cache:
+
+Glock mode   |  Cache data | Cache Metadata | Dirty Data | Dirty Metadata
+--------------------------------------------------------------------------
+    UN       |     No      |       No       |     No     |      No
+    SH       |     Yes     |       Yes      |     No     |      No
+    DF       |     No      |       Yes      |     No     |      No
+    EX       |     Yes     |       Yes      |     Yes    |      Yes
+
+These rules are implemented using the various glock operations which
+are defined for each type of glock. Not all types of glocks use
+all the modes. Only inode glocks use the DF mode for example.
+
+Table of glock operations and per type constants:
+
+Field            | Purpose
+----------------------------------------------------------------------------
+go_xmote_th      | Called before remote state change (e.g. to sync dirty data)
+go_xmote_bh      | Called after remote state change (e.g. to refill cache)
+go_inval         | Called if remote state change requires invalidating the cache
+go_demote_ok     | Returns boolean value of whether its ok to demote a glock
+                 | (e.g. checks timeout, and that there is no cached data)
+go_lock          | Called for the first local holder of a lock
+go_unlock        | Called on the final local unlock of a lock
+go_dump          | Called to print content of object for debugfs file, or on
+                 | error to dump glock to the log.
+go_type;         | The type of the glock, LM_TYPE_.....
+go_min_hold_time | The minimum hold time
+
+The minimum hold time for each lock is the time after a remote lock
+grant for which we ignore remote demote requests. This is in order to
+prevent a situation where locks are being bounced around the cluster
+from node to node with none of the nodes making any progress. This
+tends to show up most with shared mmaped files which are being written
+to by multiple nodes. By delaying the demotion in response to a
+remote callback, that gives the userspace program time to make
+some progress before the pages are unmapped.
+
+There is a plan to try and remove the go_lock and go_unlock callbacks
+if possible, in order to try and speed up the fast path though the locking.
+Also, eventually we hope to make the glock "EX" mode locally shared
+such that any local locking will be done with the i_mutex as required
+rather than via the glock.
+
+Locking rules for glock operations:
+
+Operation     |  GLF_LOCK bit lock held |  gl_spin spinlock held
+-----------------------------------------------------------------
+go_xmote_th   |       Yes               |       No
+go_xmote_bh   |       Yes               |       No
+go_inval      |       Yes               |       No
+go_demote_ok  |       Sometimes         |       Yes
+go_lock       |       Yes               |       No
+go_unlock     |       Yes               |       No
+go_dump       |       Sometimes         |       Yes
+
+N.B. Operations must not drop either the bit lock or the spinlock
+if its held on entry. go_dump and do_demote_ok must never block.
+Note that go_dump will only be called if the glock's state
+indicates that it is caching uptodate data.
+
+Glock locking order within GFS2:
+
+ 1. i_mutex (if required)
+ 2. Rename glock (for rename only)
+ 3. Inode glock(s)
+    (Parents before children, inodes at "same level" with same parent in
+     lock number order)
+ 4. Rgrp glock(s) (for (de)allocation operations)
+ 5. Transaction glock (via gfs2_trans_begin) for non-read operations
+ 6. Page lock  (always last, very important!)
+
+There are two glocks per inode. One deals with access to the inode
+itself (locking order as above), and the other, known as the iopen
+glock is used in conjunction with the i_nlink field in the inode to
+determine the lifetime of the inode in question. Locking of inodes
+is on a per-inode basis. Locking of rgrps is on a per rgrp basis.

Subject: [PATCH 192/794] powerpc: Optimise smp_wmb on 64-bit processors

For 64-bit processors, lwsync is the recommended method of store/store
ordering on caching enabled memory.  For those subarchs which have
lwsync, use it rather than eieio for smp_wmb.

Subject: [PATCH 193/794] viotape: Use unlocked_ioctl

This pushes the BKL down into the driver.  Based on a patch by Alan Cox.

We need to do it this way for now as the inode parameter of viotap_ioctl
is used internally as a flag.  We should do a further cleanup patch.

From: Segher Boessenkool <segher@kernel.crashing.org>
Date: Sun, 8 Jun 2008 09:42:52 +1000
Subject: [PATCH 199/794] powerpc: Get rid of CROSS32{AS,LD,OBJCOPY}

CROSS32AS and CROSS32LD are never used (instead, CROSS32CC is used
with proper command line options).

CROSS32OBJCOPY isn't used anymore either, since the "wrapper" stuff
was added.

Remove these unused variables.

Subject: [PATCH 203/794] powerpc: Implement OF PCI address accessors stubs for
 CONFIG_PCI=n

To avoid "#ifdef CONFIG_PCI" in the drivers we should provide stubs in
place of OF PCI address accessors.

Without these stubs build breaks for drivers not strictly requiring PCI,
for example CONFIG_FB_OF=y without CONFIG_PCI:

  LD      .tmp_vmlinux1
drivers/built-in.o: In function `offb_map_reg':
offb.c:(.text+0x6e7c): undefined reference to `of_get_pci_address'

OF PCI IRQ accessors require pci_dev argument, so drivers using PCI
IRQs should depend on CONFIG_PCI anyway.

Subject: [PATCH 204/794] powerpc: Free a PTE bit on ppc64 with 64K pages

This frees a PTE bit when using 64K pages on ppc64.  This is done
by getting rid of the separate _PAGE_HASHPTE bit.  Instead, we just test
if any of the 16 sub-page bits is set.  For non-combo pages (ie. real
64K pages), we set SUB0 and the location encoding in that field.

Subject: [PATCH 205/794] powerpc: Provide dummy crash_shutdown_register

When kexec is disabled, the crash_shutdown_{un,}register
functions are not available in the kernel.
This provides dummy inline functions for those so that
the callers don't have to worry about it.

Subject: [PATCH 211/794] powerpc: Get rid of bitfields in ppc_bat struct

While working on the 36-bit physical support, I noticed that there
was exactly one line of code that actually referenced the bitfields.
So I got rid of them and redefined ppc_bat as a struct of 2 u32's:
batu and batl.  I also got rid of the previous union that held the
bitfield structs and a word representation of the batu/l values.

This seems like a nicer solution than adding in a bunch of
new bitfields to support extended bat addressing that would never
get used, and just leaving the struct as-is would have been
incomplete in the face of large physical addressing.

From 3a8247cc2c856930f34eafce33f6a039227ee175 Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Wed, 18 Jun 2008 15:29:12 +1000
Subject: [PATCH 214/794] powerpc: Only demote individual slices rather than
 whole process

At present, if we have a kernel with a 64kB page size, and some
process maps something that has to be mapped with 4kB pages (such as a
cache-inhibited mapping on POWER5+, or the eHCA infiniband queue-pair
pages), we change the process to use 4kB pages everywhere.  This hurts
the performance of HPC programs that access eHCA from userspace.

With this patch, the kernel will only demote the slice(s) containing
the eHCA or cache-inhibited mappings, leaving the remaining slices
able to use 64kB hardware pages.

This also changes the slice_get_unmapped_area code so that it is
willing to place a 64k-page mapping into (or across) a 4k-page slice
if there is no better alternative, i.e. if the program specified
MAP_FIXED or if there is not sufficient space available in slices that
are either empty or already have 64k-page mappings in them.

Subject: [PATCH 219/794] drivers/macintosh: Various cleanups

This contains the following cleanups:
- make the following needlessly global code static:
  - adb.c: adb_controller
  - adb.c: adb_init()
  - adbhid.c: adb_to_linux_keycodes[]  (also make it const)
  - via-pmu68k.c: backlight_level
  - via-pmu68k.c: backlight_enabled
- remove the following unused code:
  - via-pmu68k.c: sleep_notifier_list

Subject: [PATCH 222/794] drivers/macintosh/smu.c: Improve error handling

This makes two changes:

* As noted by Akinobu Mita in patch
b1fceac2b9e04d278316b2faddf276015fc06e3b, alloc_bootmem never returns NULL
and always returns a zeroed region of memory.  Thus the error checking code
and memset after the call to alloc_bootmem are not necessary.

* The old error handling code consisted of setting a global variable to
NULL and returning an error code, which could cause previously allocated
resources never to be freed.  The patch adds calls to appropriate resource
deallocation functions.

Subject: [PATCH 223/794] powerpc: Move code patching code into
 arch/powerpc/lib/code-patching.c

We currently have a few routines for patching code in asm/system.h, because
they didn't fit anywhere else. I'd like to clean them up a little and add
some more, so first move them into a dedicated C file - they don't need to
be inlined.

While we're moving the code, drop create_function_call(), it's intended
caller never got merged and will be replaced in future with something
different.

Subject: [PATCH 224/794] powerpc: Allow create_branch() to return errors

Currently create_branch() creates a branch instruction for you, and
patches it into the call site.  In some circumstances it would be nice
to be able to create the instruction and patch it later, and also some
code might want to check for errors in the branch creation before
doing the patching.  A future commit will change create_branch() to
check for errors.

For callers that don't care, replace create_branch() with
patch_branch(), which just creates the branch and patches it directly.

While we're touching all the callers, change to using unsigned int *,
as this seems to match usage better.  That allows (and requires) us to
remove the volatile in the definition of vector in powermac/smp.c and
mpc86xx_smp.c, that's correct because now that we're passing vector as
an unsigned int * the compiler knows that it's value might change
across the patch_branch() call.

Subject: [PATCH 225/794] powerpc: Make create_branch() return errors if the
 branch target is too large

If you pass a target value to create_branch() which is more than 32MB - 4,
or - 32MB away from the branch site, then it's impossible to create an
immediate branch.  The current code doesn't check, which will lead to us
creating a branch to somewhere else - which is bad.

For code that cares to check we return 0, which is easy to check for, and
for code that doesn't at least we'll be creating an illegal instruction,
rather than a branch to some random address.

Subject: [PATCH 226/794] powerpc: Add ppc_function_entry() which gets the
 entry point for a function

Because function pointers point to different things on 32-bit vs 64-bit,
add a macro that deals with dereferencing the OPD on 64-bit.  The soon to
be merged ftrace wants this, as well as other code I am working on.

Subject: [PATCH 229/794] powerpc: Add PPC_NOP_INSTR, a hash define for the
 preferred nop instruction

A bunch of code has hard-coded the value for a "nop" instruction, it
would be nice to have a #define for it.

Subject: [PATCH 230/794] powerpc: Split out do_feature_fixups() from
 cputable.c

The logic to patch CPU feature sections lives in cputable.c, but these days
it's used for CPU features as well as firmware features.  Move it into
it's own file for neatness and as preparation for some additions.

While we're moving the code, we pull the loop body logic into a separate
routine, and remove a comment which doesn't apply anymore.

Subject: [PATCH 232/794] powerpc: Consolidate feature fixup macros for 64/32
 bit

Currently we have three versions of MAKE_FTR_SECTION_ENTRY(), the macro that
generates a feature section entry.  There is 64bit version, a 32bit version
and version for 32bit code built with a 64bit kernel.

Rather than triplicating (?) the MAKE_FTR_SECTION_ENTRY() logic, we can
move the 64bit/32bit differences into separate macros, and then only have
one version of MAKE_FTR_SECTION_ENTRY().

Subject: [PATCH 233/794] powerpc: Introduce infrastructure for feature
 sections with alternatives

The current feature section logic only supports nop'ing out code, this means
if you want to choose at runtime between instruction sequences, one or both
cases will have to execute the nop'ed out contents of the other section, eg:

BEGIN_FTR_SECTION
	or	1,1,1
END_FTR_SECTION_IFSET(FOO)
BEGIN_FTR_SECTION
	or	2,2,2
END_FTR_SECTION_IFCLR(FOO)

and the resulting code will be either,

	or	1,1,1
	nop

or,
	nop
	or	2,2,2

For small code segments this is fine, but for larger code blocks and in
performance criticial code segments, it would be nice to avoid the nops.
This commit starts to implement logic to allow the following:

BEGIN_FTR_SECTION
	or	1,1,1
FTR_SECTION_ELSE
	or	2,2,2
ALT_FTR_SECTION_END_IFSET(FOO)

and the resulting code will be:

	or	1,1,1
or,
	or	2,2,2

We achieve this by extending the existing FTR macros. The current feature
section semantic just becomes a special case, ie. if the else case is empty
we nop out the default case.

The key limitation is that the size of the else case must be less than or
equal to the size of the default case. If the else case is smaller the
remainder of the section is nop'ed.

We let the linker put the else case code in with the rest of the text,
so that relative branches from the else case are more likley to link,
this has the disadvantage that we can't free the unused else cases.

This commit introduces the required macro and linker script changes, but
does not enable the patching of the alternative sections.

We also need to update two hand-made section entries in reg.h and timex.h

Subject: [PATCH 234/794] powerpc: Add logic to patch alternative feature
 sections

This commit adds the logic to patch alternative sections.  This is fairly
straightforward, except for branches.  Relative branches that jump from
inside the else section to outside of it need to be translated as they're
moved, otherwise they will jump to the wrong location.

Subject: [PATCH 235/794] powerpc: Add self-tests of the feature fixup code

This commit adds tests of the feature fixup code, they are run during
boot if CONFIG_FTR_FIXUP_SELFTEST=y. Some of the tests manually invoke
the patching routines to check their behaviour, and others use the
macros and so are patched during the normal patching done during boot.

Because we have two sets of macros with different names, we use a macro
to generate the test of the macros, very niiiice.

Subject: [PATCH 236/794] powerpc: Use an alternative feature section in
 entry_64.S

Use an alternative feature section in _switch. There are three cases
handled here, either we don't have an SLB, in which case we jump over the
entire code section, or if we do we either do or don't have 1TB segments.

Boot tested on Power3, Power5 and Power5+.

From: Tony Breeds <tony@bakeyournoodle.com>
Date: Tue, 24 Jun 2008 14:20:29 +1000
Subject: [PATCH 237/794] powerpc: Change the default link address for pSeries
 zImage kernels

Currently we set the start of the .text section to be 4Mb for pSeries.
In situations where the zImage is > 8Mb we'll fail to boot (due to
overlapping with OF).  Move .text in a zImage from 4MB to 64MB
(well past OF).

We still will not be able to load large zImage unless we also move OF,
to that end, add a note to the zImage ELF to move OF to 32Mb.  If this
is the very first kernel booted then we'll need to move OF manually by
setting real-base.

Subject: [PATCH 238/794] powerpc: Fix MSR setting in 32 bit signal code

If we set the SPE MSR bit in save_user_regs we can blow away the VEC
bit.  This doesn't matter in reality as they are in fact the same bit
but looks bad.

Also, when we add VSX in a later patch, we need to be able to set two
separate MSR bits here.

Subject: [PATCH 239/794] powerpc: Add macros to access floating point
 registers in thread_struct.

We are going to change where the floating point registers are stored
in the thread_struct, so in preparation add some macros to access the
floating point registers.  Update all code to use these new macros.

Subject: [PATCH 242/794] powerpc: Introduce VSX thread_struct and CONFIG_VSX

The layout of the new VSR registers and how they overlap on top of the
legacy FPR and VR registers is:

          ----------------------------------------------------------------
  VSR[32] |                             VR[0]                            |
          ----------------------------------------------------------------

          ----------------------------------------------------------------
  VSR[62] |                             VR[30]                           |
          ----------------------------------------------------------------
  VSR[63] |                             VR[31]                           |
          ----------------------------------------------------------------

VSX has 64 128bit registers.  The first 32 regs overlap with the FP
registers and hence extend them with and additional 64 bits.  The
second 32 regs overlap with the VMX registers.

This commit introduces the thread_struct changes required to reflect
this register layout.  Ptrace and signals code is updated so that the
floating point registers are correctly accessed from the thread_struct
when CONFIG_VSX is enabled.

This adds the macros for the VSX load/store instruction as most
binutils are not going to support this for a while.

Also add VSX register save/restore macros and vsr[0-63] register definitions.

Subject: [PATCH 245/794] powerpc: Add VSX context save/restore, ptrace and
 signal support

This patch extends the floating point save and restore code to use the
VSX load/stores when VSX is available.  This will make FP context
save/restore marginally slower on FP only code, when VSX is available,
as it has to load/store 128bits rather than just 64bits.

Mixing FP, VMX and VSX code will get constant architected state.

The signals interface is extended to enable access to VSR 0-31
doubleword 1 after discussions with tool chain maintainers.  Backward
compatibility is maintained.

The ptrace interface is also extended to allow access to VSR 0-31 full
registers.

Subject: [PATCH 248/794] powerpc: Prevent memory corruption due to cache
 invalidation of unaligned DMA buffer

On PowerPC processors with non-coherent cache architectures the DMA
subsystem calls invalidate_dcache_range() before performing a DMA read
operation.  If the address and length of the DMA buffer are not aligned
to a cache-line boundary this can result in memory outside of the DMA
buffer being invalidated in the cache.  If this memory has an
uncommitted store then the data will be lost and a subsequent read of
that address will result in an old value being returned from main memory.

Only when the DMA buffer starts on a cache-line boundary and is an exact
mutiple of the cache-line size can invalidate_dcache_range() be called,
otherwise flush_dcache_range() must be called.  flush_dcache_range()
will first flush uncommitted writes, and then invalidate the cache.

Subject: [PATCH 249/794] powerpc: Add 64 bit version of
 huge_ptep_set_wrprotect

The implementation of huge_ptep_set_wrprotect() directly calls
ptep_set_wrprotect() to mark a hugepte write protected.  However this
call is not appropriate on ppc64 kernels as this is a small page only
implementation.  This can lead to the hash not being flushed correctly
when a mapping is being converted to COW, allowing processes to continue
using the original copy.

Currently huge_ptep_set_wrprotect() unconditionally calls
ptep_set_wrprotect().  This is fine on ppc32 kernels as this call is
generic.  On 64 bit this is implemented as:

	pte_update(mm, addr, ptep, _PAGE_RW, 0);

On ppc64 this last parameter is the page size and is passed directly on
to hpte_need_flush():

	hpte_need_flush(mm, addr, ptep, old, huge);

And this directly affects the page size we pass to flush_hash_page():

	flush_hash_page(vaddr, rpte, psize, ssize, 0);

As this changes the way the hash is calculated we will flush the wrong
pages, potentially leaving live hashes to the original page.

Move the definition of huge_ptep_set_wrprotect() to the 32/64 bit specific
headers.

Subject: [PATCH 252/794] powerpc: Make sure that
 include/asm-powerpc/spinlock.h does not trigger compilation warnings

When compiling kernel modules for ppc that include <linux/spinlock.h>,
gcc prints a warning message every time it encounters a function
declaration where the inline keyword appears after the return type.
This makes sure that the order of the inline keyword and the return
type is as gcc expects it.  Additionally, the __inline__ keyword is
replaced by inline, as checkpatch expects.

Date: Tue, 1 Jul 2008 02:12:13 +1000
Subject: [PATCH 253/794] powerpc: Keep 3 high personality bytes across exec

Currently when a 32 bit process is exec'd on a powerpc 64 bit host the
value in the top three bytes of the personality is clobbered.  patch
adds a check in the SET_PERSONALITY macro that will carry all the
values in the top three bytes across the exec.

These three bytes currently carry flags to disable address randomisation,
limit the address space, force zeroing of an mmapped page, etc.  Should an
application set any of these bits they will be maintained and honoured on
homogeneous environment but discarded and ignored on a heterogeneous
environment.  So if an application requires all mmapped pages to be initialised
to zero and a wrapper is used to setup the personality and exec the target,
these flags will remain set on an all 32 or all 64 bit envrionment, but they
will be lost in the exec on a mixed 32/64 bit environment.  Losing these bits
means that the same application would behave differently in different
environments.  Tested on a POWER5+ machine with 64bit kernel and a mixed
64/32 bit user space.

This correctly hooks the VSX dump into Roland McGrath core file
infrastructure.  It adds the VSX dump information as an additional elf
note in the core file (after talking more to the tool chain/gdb guys).
This also ensures the formats are consistent between signals, ptrace
and core files.

Subject: [PATCH 259/794] powerpc: Fixup lwsync at runtime

To allow for a single kernel image on e500 v1/v2/mc we need to fixup lwsync
at runtime.  On e500v1/v2 lwsync causes an illop so we need to patch up
the code.  We default to 'sync' since that is always safe and if the cpu
is capable we will replace 'sync' with 'lwsync'.

We introduce CPU_FTR_LWSYNC as a way to determine at runtime if this is
needed.  This flag could be moved elsewhere since we dont really use it
for the normal CPU_FTR purpose.

Finally we only store the relative offset in the fixup section to keep it
as small as possible rather than using a full fixup_entry.

From 6a274c08f2f4dfac7167bbd849621f3a2b55d424 Mon Sep 17 00:00:00 2001
From: Michael Neuling <mikey@neuling.org>
Date: Wed, 2 Jul 2008 14:06:37 +1000
Subject: [PATCH 260/794] powerpc: Clean up copy_to/from_user for vsx and fpr

This merges and cleans up some of the ugly copy/to from user code
which is required for the new fpr and vsx layout in the thread_struct.

Also fixes some hard coded buffer sizes and removes a redundant
fpr_flush_to_thread.

Subject: [PATCH 262/794] powerpc/pseries: Allow phandle to be specified in
 formats other than decimal

Allow the phandle passed to the /proc/ppc64/ofdt file to be specified
in formats other than decimal.  This allows us to easily specify phandle
values in hex that would otherwise appear as negative integers.

This is an issue on systems where the value of
/proc/device-tree/ibm,dynamic-reconfiguration-memory.ibm,phandle is
fffffff9.  Having to pass this to the ofdt file as a string results in
a large negative number, and simple_strtoul() does not handle negative
numbers.

Subject: [PATCH 263/794] powerpc/pseries: Use base address to derive starting
 page frame number

Use the base address of the lmb to derive the starting page frame number
instead of trying to extract it from the drc index of the lmb.  The drc
index should not be used for this as it will, and did, break.

Until this point, systems that have had memory represented in the device
tree with a node for each lmb the drc index would (luckily) closely
track the base address of the lmb.  For example a lmb with a drc index
of 8000000a would have a base address of a0000000.  This correlation
allowed the current code to derive the starting page frame number from
the drc inddex

Device tree layouts where lmbs are represented under the
ibm,dynamic-reconfiguration-memory node in the ibm,dynamic-memory
property do not have this correlation between the drc index and base
address of the lmb.

Subject: [PATCH 264/794] powerpc/pseries: Update the device tree correctly for
 drconf memory add/remove

This updates the device tree manipulation routines so that memory
add/remove of lmbs represented under the
ibm,dynamic-reconfiguration-memory node of the device tree invokes the
hotplug notifier chain.

This change is needed because of the change in the way memory is
represented under the ibm,dynamic-reconfiguration-memory node.  All lmbs
are described in the ibm,dynamic-memory property instead of having a
separate node for each lmb as in previous device tree layouts.  This
requires the update_node() routine to check for updates to the
ibm,dynamic-memory property and invoke the hotplug notifier chain.

This also updates the pseries hotplug notifier to be able to gather information
for lmbs represented under the ibm,dynamic-reconfiguration-memory node and
have the lmbs added/removed.

Subject: [PATCH 265/794] powerpc/pseries: Split code into helper routines for
 drconf memory

This splits off several pieces of code that parse the
ibm,dynamic-reconfiguration-memory node of the device tree into separate
helper routines.  This is in preparation for the next commit that will
use these helper routines.  There are no functional changes in this patch.

Subject: [PATCH 266/794] powerpc/pseries: Update numa association of hotplug
 memory add for drconf memory

Update the association of a memory section with a numa node that
occurs during hotplug add of a memory section.  This adds a check in
the hot_add_scn_to_nid() routine for the
ibm,dynamic-reconfiguration-memory node in the device tree.  If
present the new hot_add_drconf_scn_to_nid() routine is invoked, which
can properly parse the ibm,dynamic-reconfiguration-memory node of the
device tree and make the proper numa node associations.

This also introduces the valid_hot_add_scn() routine as a helper
function for code that is common to the hot_add_scn_to_nid() and
hot_add_drconf_scn_to_nid() routines.

Subject: [PATCH 269/794] [GFS2] don't call permission()

GFS2 calls permission() to verify permissions after locks on the files
have been taken.

For this it's sufficient to call gfs2_permission() instead.  This
results in the following changes:

  - IS_RDONLY() check is not performed
  - IS_IMMUTABLE() check is not performed
  - devcgroup_inode_permission() is not called
  - security_inode_permission() is not called

IS_RDONLY() should be unnecessary anyway, as the per-mount read-only
flag should provide protection against read-only remounts during
operations.  do_gfs2_set_flags() has been fixed to perform
mnt_want_write()/mnt_drop_write() to protect against remounting
read-only.

IS_IMMUTABLE has been added to gfs2_permission()

Repeating the security checks seems to be pointless, as they don't
normally change, and if they do, it's independent of the filesystem
state.

From d58577d8f36f66dbb5dec30fc01dfddda0cfd1fa Mon Sep 17 00:00:00 2001
From: John Linn <john.linn@xilinx.com>
Date: Wed, 2 Jul 2008 15:11:28 -0700
Subject: [PATCH 271/794] powerpc/virtex: Fix booting of Xilinx FPGAs with
 16550 for 405 and 440

The following changes add processing to initialize the Xilinx 16550 UART
in the boot wrapper for Virtex targets without firmware.  Normally the
boot wrapper assumes that the serial port has already been initialized by
firmware.

The wrapper was also modified to add the 440 build.

+The PowerPC boot wrapper
+------------------------
+Copyright (C) Secret Lab Technologies Ltd.
+
+PowerPC image targets compresses and wraps the kernel image (vmlinux) with
+a boot wrapper to make it usable by the system firmware.  There is no
+standard PowerPC firmware interface, so the boot wrapper is designed to
+be adaptable for each kind of image that needs to be built.
+
+The boot wrapper can be found in the arch/powerpc/boot/ directory.  The
+Makefile in that directory has targets for all the available image types.
+The different image types are used to support all of the various firmware
+interfaces found on PowerPC platforms.  OpenFirmware is the most commonly
+used firmware type on general purpose PowerPC systems from Apple, IBM and
+others.  U-Boot is typically found on embedded PowerPC hardware, but there
+are a handful of other firmware implementations which are also popular.  Each
+firmware interface requires a different image format.
+
+The boot wrapper is built from the makefile in arch/powerpc/boot/Makefile and
+it uses the wrapper script (arch/powerpc/boot/wrapper) to generate target
+image.  The details of the build system is discussed in the next section.
+Currently, the following image format targets exist:
+
+   cuImage.%:		Backwards compatible uImage for older version of
+			U-Boot (for versions that don't understand the device
+			tree).  This image embeds a device tree blob inside
+			the image.  The boot wrapper, kernel and device tree
+			are all embedded inside the U-Boot uImage file format
+			with boot wrapper code that extracts data from the old
+			bd_info structure and loads the data into the device
+			tree before jumping into the kernel.
+			  Because of the series of #ifdefs found in the
+			bd_info structure used in the old U-Boot interfaces,
+			cuImages are platform specific.  Each specific
+			U-Boot platform has a different platform init file
+			which populates the embedded device tree with data
+			from the platform specific bd_info file.  The platform
+			specific cuImage platform init code can be found in
+			arch/powerpc/boot/cuboot.*.c.  Selection of the correct
+			cuImage init code for a specific board can be found in
+			the wrapper structure.
+   dtbImage.%:		Similar to zImage, except device tree blob is embedded
+			inside the image instead of provided by firmware.  The
+			output image file can be either an elf file or a flat
+			binary depending on the platform.
+			  dtbImages are used on systems which do not have an
+			interface for passing a device tree directly.
+			dtbImages are similar to simpleImages except that
+			dtbImages have platform specific code for extracting
+			data from the board firmware, but simpleImages do not
+			talk to the firmware at all.
+			  PlayStation 3 support uses dtbImage.  So do Embedded
+			Planet boards using the PlanetCore firmware.  Board
+			specific initialization code is typically found in a
+			file named arch/powerpc/boot/<platform>.c; but this
+			can be overridden by the wrapper script.
+   simpleImage.%:	Firmware independent compressed image that does not
+			depend on any particular firmware interface and embeds
+			a device tree blob.  This image is a flat binary that
+			can be loaded to any location in RAM and jumped to.
+			Firmware cannot pass any configuration data to the
+			kernel with this image type and it depends entirely on
+			the embedded device tree for all information.
+			  The simpleImage is useful for booting systems with
+			an unknown firmware interface or for booting from
+			a debugger when no firmware is present (such as on
+			the Xilinx Virtex platform).  The only assumption that
+			simpleImage makes is that RAM is correctly initialized
+			and that the MMU is either off or has RAM mapped to
+			base address 0.
+			  simpleImage also supports inserting special platform
+			specific initialization code to the start of the bootup
+			sequence.  The virtex405 platform uses this feature to
+			ensure that the cache is invalidated before caching
+			is enabled.  Platform specific initialization code is
+			added as part of the wrapper script and is keyed on
+			the image target name.  For example, all
+			simpleImage.virtex405-* targets will add the
+			virtex405-head.S initialization code (This also means
+			that the dts file for virtex405 targets should be
+			named (virtex405-<board>.dts).  Search the wrapper
+			script for 'virtex405' and see the file
+			arch/powerpc/boot/virtex405-head.S for details.
+   treeImage.%;		Image format for used with OpenBIOS firmware found
+			on some ppc4xx hardware.  This image embeds a device
+			tree blob inside the image.
+   uImage:		Native image format used by U-Boot.  The uImage target
+			does not add any boot code.  It just wraps a compressed
+			vmlinux in the uImage data structure.  This image
+			requires a version of U-Boot that is able to pass
+			a device tree to the kernel at boot.  If using an older
+			version of U-Boot, then you need to use a cuImage
+			instead.
+   zImage.%:		Image format which does not embed a device tree.
+			Used by OpenFirmware and other firmware interfaces
+			which are able to supply a device tree.  This image
+			expects firmware to provide the device tree at boot.
+			Typically, if you have general purpose PowerPC
+			hardware then you want this image format.
+
+Image types which embed a device tree blob (simpleImage, dtbImage, treeImage,
+and cuImage) all generate the device tree blob from a file in the
+arch/powerpc/boot/dts/ directory.  The Makefile selects the correct device
+tree source based on the name of the target.  Therefore, if the kernel is
+built with 'make treeImage.walnut simpleImage.virtex405-ml403', then the
+build system will use arch/powerpc/boot/dts/walnut.dts to build
+treeImage.walnut and arch/powerpc/boot/dts/virtex405-ml403.dts to build
+the simpleImage.virtex405-ml403.
+
+Two special targets called 'zImage' and 'zImage.initrd' also exist.  These
+targets build all the default images as selected by the kernel configuration.
+Default images are selected by the boot wrapper Makefile
+(arch/powerpc/boot/Makefile) by adding targets to the $image-y variable.  Look
+at the Makefile to see which default image targets are available.
+
+How it is built
+---------------
+arch/powerpc is designed to support multiplatform kernels, which means
+that a single vmlinux image can be booted on many different target boards.
+It also means that the boot wrapper must be able to wrap for many kinds of
+images on a single build.  The design decision was made to not use any
+conditional compilation code (#ifdef, etc) in the boot wrapper source code.
+All of the boot wrapper pieces are buildable at any time regardless of the
+kernel configuration.  Building all the wrapper bits on every kernel build
+also ensures that obscure parts of the wrapper are at the very least compile
+tested in a large variety of environments.
+
+The wrapper is adapted for different image types at link time by linking in
+just the wrapper bits that are appropriate for the image type.  The 'wrapper
+script' (found in arch/powerpc/boot/wrapper) is called by the Makefile and
+is responsible for selecting the correct wrapper bits for the image type.
+The arguments are well documented in the script's comment block, so they
+are not repeated here.  However, it is worth mentioning that the script
+uses the -p (platform) argument as the main method of deciding which wrapper
+bits to compile in.  Look for the large 'case "$platform" in' block in the
+middle of the script.  This is also the place where platform specific fixups
+can be selected by changing the link order.
+
+In particular, care should be taken when working with cuImages.  cuImage
+wrapper bits are very board specific and care should be taken to make sure
+the target you are trying to build is supported by the wrapper bits.

 target

The wrapper script is missing the bits needed for building generic
simpleImage targets (targets which don't depend on any particular
firmware interface and retrieve all their data from the device tree).

Subject: [PATCH 279/794] [GFS2] Fix delayed demote race

There is a race in the delayed demote code where it does the wrong thing
if a demotion to UN has occurred for other reasons before the delay has
expired. This patch adds an assert to catch that condition as well as
fixing the root cause by adding an additional check for the UN state.

Subject: [PATCH 280/794] [GFS2] Allow local DF locks when holding a cached EX
 glock

We already allow local SH locks while we hold a cached EX glock, so here
we allow DF locks as well. This works only because we rely on the VFS's
invalidation for locally cached data, and because if we hold an EX lock,
then we know that no other node can be caching data relating to this
file.

It dramatically speeds up initial writes to O_DIRECT files since we fall
back to buffered I/O for this and would otherwise bounce between DF and
EX modes on each and every write call. The lessons to be learned from
that are to ensure that (for the time being anyway) O_DIRECT files are
preallocated and that they are written to using reasonably large I/O
sizes. Even so this change fixes that corner case nicely

Subject: [PATCH 282/794] powerpc/spufs: provide context debug file

Add a ctxt file to spufs that shows spu context information that is used
in scheduling. This info can be used for debugging spufs scheduler
issues, and to isolate between application and spufs problems as it
shows a lot of state such as priorities and dispatch counts.

This file contains internal spufs state and is subject to change at any
time, and therefore no applications should depend on it.  The file is
intended for the use of spufs kernel developers.

An spu context shouldn't get an extra tick if the time slice code

within spu_run (ie, SPU_SCHED_SPU_RUN is cleared) will not receive
extra ticks while we have no other contexts waiting.

Subject: [PATCH 285/794] powerpc/spufs: allow spufs files to specify sizes

Currently, spufs never specifies the i_size for the files in context
directories, so stat() always reports 0-byte files.

This change adds allows the spufs_dir_(nosched_)contents arrays to
specify a file size. This allows stat() to report correct file sizes,
and makes SEEK_END work.

Subject: [PATCH 286/794] powerpc/spufs: add sizes for context files

Populate the size member of a few context files. Leave out files that
have different semantics with read vs mmap, or contain a
variable-length hex string.

Subject: [PATCH 287/794] powerpc/spufs: only add ".ctx" file with "debug"
 mount option

Currently, the .ctx debug file in spu context directories is always
present.

We'd prefer to prevent users from relying on this file, so add a
"debug" mount option to spufs. The .ctx file will only be added to
the context directories when this option is present.

Subject: [PATCH 289/794] powerpc/spufs: add atomic busy_spus counter to struct
 cbe_spu_info

As nr_active counter includes also spus waiting for syscalls to return
we need a seperate counter that only counts spus that are currently running
on spu side. This counter shall be used by a cpufreq governor that targets
a frequency dependent from the number of running spus.

Subject: [PATCH 290/794] powerpc/dma: Add struct iommu_table argument to
 iommu_map_sg()

Make iommu_map_sg take a struct iommu_table. It did so before commit
740c3ce66700640a6e6136ff679b067e92125794 (iommu sg merging: ppc: make
iommu respect the segment size limits).

This stops the function looking in the archdata.dma_data for the iommu
table because in the future it will be called with a device that has
no table there.

This also has the nice side effect of making iommu_map_sg() match the
other map functions.

Subject: [PATCH 291/794] powerpc/dma: implement new dma_*map*_attrs()
 interfaces

Update powerpc to use the new dma_*map*_attrs() interfaces. In doing so
update struct dma_mapping_ops to accept a struct dma_attrs and propagate
these changes through to all users of the code (generic IOMMU and the
64bit DMA code, and the iseries and ps3 platform code).

The old dma_*map_*() interfaces are reimplemented as calls to the
corresponding new interfaces.

Subject: [PATCH 292/794] powerpc/cell: cell_dma_dev_setup_iommu() return the
 iommu table

Make cell_dma_dev_setup_iommu() return a pointer to the struct iommu_table
(or NULL if no table can be found) rather than putting this pointer into
dev->archdata.dma_data (let the caller do that), and rename this function
to cell_get_iommu_table() to reflect this change.

This will allow us to get the iommu table for a device that doesn't have
the table in the archdata.

Subject: [PATCH 296/794] mm: Allow architectures to define additional
 protection bits

This patch allows architectures to define functions to deal with
additional protections bits for mmap() and mprotect().

arch_calc_vm_prot_bits() maps additonal protection bits to vm_flags
arch_vm_get_page_prot() maps additional vm_flags to the vma's vm_page_prot
arch_validate_prot() checks for valid values of the protection bits

Note: vm_get_page_prot() is now pretty ugly, but the generated code
should be identical for architectures that don't define additional
protection bits.

Subject: [PATCH 299/794] powerpc/mm: Add Strong Access Ordering support

Allow an application to enable Strong Access Ordering on specific pages of
memory on Power 7 hardware. Currently, power has a weaker memory model than
x86. Implementing a stronger memory model allows an emulator to more
efficiently translate x86 code into power code, resulting in faster code
execution.

On Power 7 hardware, storing 0b1110 in the WIMG bits of the hpte enables
strong access ordering mode for the memory page.  This patchset allows a
user to specify which pages are thus enabled by passing a new protection
bit through mmap() and mprotect().  I have defined PROT_SAO to be 0x10.

Subject: [PATCH 300/794] powerpc/mm: Don't clear _PAGE_COHERENT when _PAGE_SAO
 is set

The current low level hash code on LPAR configurations clears
_PAGE_COHERENT (M) when either _PAGE_GUARDED (G) or _PAGE_NO_CACHE (I)
is set. This conflicts with _PAGE_SAO which has M, I and W bits sets at
once (normally invalid combo) to indicate the new SAO attribute.

This changes the code to allow that case.

Subject: [PATCH 301/794] ibm_newemac: Parameterize EMAC Multicast Match
 Handling

Various instances of the EMAC core have varying: 1) number of address
match slots, 2) width of the registers for handling address match slots,
3) number of registers for handling address match slots and 4) base
offset for those registers.

As the driver stands today, it assumes that all EMACs have 4 IAHT and
GAHT 32-bit registers, starting at offset 0x30 from the register base,
with only 16-bits of each used for a total of 64 match slots.

The 405EX(r) and 460EX now use the EMAC4SYNC core rather than the EMAC4
core. This core has 8 IAHT and GAHT registers, starting at offset 0x80
from the register base, with ALL 32-bits of each used for a total of
256 match slots.

This adds a new compatible device tree entry "emac4sync" and a new,
related feature flag "EMAC_FTR_EMAC4SYNC" along with a series of macros
and inlines which supply the appropriate parameterized value based on
the presence or absence of the EMAC4SYNC feature.

The code has further been reworked where appropriate to use those macros
and inlines.

In addition, the register size passed to ioremap is now taken from the
device tree:

	c4 for EMAC4SYNC cores
	74 for EMAC4 cores
	70 for EMAC cores

rather than sizeof (emac_regs).

Finally, the device trees have been updated with the appropriate compatible
entries and resource sizes.

This has been tested on an AMCC Haleakala board such that: 1) inbound
ICMP requests to 'haleakala.local' via MDNS from both Mac OS X 10.4.11
and Ubuntu 8.04 systems as well as 2) outbound ICMP requests from
'haleakala.local' to those same systems in the '.local' domain via MDNS
now work.

Subject: [PATCH 303/794] powerpc: fix swapcontext backwards compat. with VSX
 ucontext changes

When the ucontext changed to add the VSX context, this broke backwards
compatibly on swapcontext.  swapcontext only compares the ucontext size
passed in from the user to the new kernel ucontext size.

This adds a check against the old ucontext size (with VMX but without
VSX).  It also adds some sanity check for ucontexts without VSX, but
where VSX is used according the MSR.  Fixes for both 32 and 64bit
processes on 64bit kernels

Kudos to Paulus for noticing.

Subject: [PATCH 305/794] powerpc/eeh: PERR/SERR bit settings during EEH device
 recovery

The following patch restores the PERR and SERR bits in the PCI
command register during an EEH device recovery. We have found
at least one case (an Agilent test card) where the PERR/SERR
bits are set to 1 by firmware at boot time, but are not restored
to 1 during EEH recovery.  The patch fixes the Agilent card
problem.  It has been tested on several other EEH-enabled cards
with no regressions.

It is inconvenient to add additional default targets to the bootwrapper

Subject: [PATCH 308/794] powerpc: rework 4xx PTE access and TLB miss

This is some preliminary work to improve TLB management on SW loaded
TLB powerpc platforms. This introduce support for non-atomic PTE
operations in pgtable-ppc32.h and removes write back to the PTE from
the TLB miss handlers. In addition, the DSI interrupt code no longer
tries to fixup write permission, this is left to generic code, and
_PAGE_HWWRITE is gone.

Subject: [PATCH 311/794] powerpc: Fix problems with 32bit PPC's running with
 >= 4GB of RAM

This patch enables 32bit PPC's (with 36bit physical address space, e.g.
IBM/AMCC PPC44x) to run with >= 4GB of RAM. Mostly its just replacing types
(unsigned long -> phys_addr_t).

Tested on an AMCC Katmai with 4GB of DDR2.

fix:

 arch/x86/kernel/built-in.o: In function `smp_intr_init':
 (.init.text+0x49e2): undefined reference to `call_function_single_interrupt'

Caused by include/asm-x86/mach-visws/entry_arch.h getting out of sync
with the include/asm-x86/mach-default/entry_arch.h file it derives from.

Copy the default file over - next step will be to simply include the default
file.

Subject: [PATCH 316/794] [GFS2] Replace rgrp "recent list" with mru list

This patch removes the "recent list" which is used during allocation
and replaces it with the (already existing) mru list used during
deletion. The "recent list" was not a true mru list leading to a number
of inefficiencies including a "next" function which made scanning the
list an order N^2 operation wrt to the number of list elements.

This should increase allocation performance with large numbers of rgrps.
Its also a useful preparation and cleanup before some further changes
which are planned in this area.

Subject: [PATCH 317/794] [GFS2] Remove support for unused and pointless flag

The ability to mark files for direct i/o access when opened
normally is both unused and pointless, so this patch removes
support for that feature.

Subject: [PATCH 319/794] nohz: don't stop idle tick if softirqs are pending.

In case a cpu goes idle but softirqs are pending only an error message is
printed to the console. It may take a very long time until the pending
softirqs will finally be executed. Worst case would be a hanging system.

With this patch the timer tick just continues and the softirqs will be
executed after the next interrupt. Still a delay but better than a
hanging system.

Currently we have at least two device drivers on s390 which under certain
circumstances schedule a tasklet from process context. This is a reason
why we can end up with pending softirqs when going idle. Fixing these
drivers seems to be non-trivial.
However there is no question that the drivers should be fixed.
This patch shouldn't be considered as a bug fix. It just is intended to
keep a system running even if device drivers are buggy.

Fix GFS2's need_sync()'s use of do_div() on an s64 by using div_s64() instead.

This does assume that gt_quota_scale_den can be cast to an s32.

This was introduced by patch b3b94faa5fe5968827ba0640ee9fba4b3e7f736e.

If the orphan node list includes valid, untruncatable nodes with nlink > 0
the ext4_orphan_cleanup loop which attempts to delete them will not do so,
causing it to loop forever. Fix by checking for such nodes in the
ext4_orphan_get function.

This patch fixes the second case (image hdb.20000009.softlockup.gz)
reported in http://bugzilla.kernel.org/show_bug.cgi?id=10882.

Subject: [PATCH 322/794] ext4: handle deleting corrupted indirect blocks

While freeing indirect blocks we attach a journal head to the parent buffer
head, free the blocks, then journal the parent. If the indirect block list
is corrupted and points to the parent the journal head will be detached
when the block is cleared, causing an OOPS.

Check for that explicitly and handle it gracefully.

This patch fixes the third case (image hdb.20000057.nullderef.gz)
reported in http://bugzilla.kernel.org/show_bug.cgi?id=10882.

Subject: [PATCH 323/794] ext4: validate directory entry data before use

ext4_dx_find_entry uses ext4_next_entry without verifying that the entry is
valid. If its rec_len == 0 this causes an infinite loop. Refactor the loop
to check the validity of entries before checking whether they match and
moving onto the next one.

There are other uses of ext4_next_entry in this file which also look
problematic. They should be reviewed and fixed if/when we have a test-case
that triggers them.

This patch fixes the first case (image hdb.25.softlockup.gz) reported in
http://bugzilla.kernel.org/show_bug.cgi?id=10882.

Subject: [PATCH 324/794] ext4: Fix mb_find_next_bit not to return larger than
 max

Some architectures implement ext4_find_next_bit and
ext4_find_next_zero_bit in such a way that they return
greater than max for some input values. Make sure
mb_find_next_bit and mb_find_next_zero_bit return the
right values.

On 2.6.25 we have include/asm-x86/bitops_32.h
static inline unsigned find_first_bit(const unsigned long *addr, unsigned size)
{
	unsigned x = 0;

	while (x < size) {
		unsigned long val = *addr++;
		if (val)
			return __ffs(val) + x;
		x += (sizeof(*addr)<<3);
	}
	return x;
}

This can return value greater than size.

Reported and fixed here for lustre

Subject: [PATCH 330/794] ext4: Fix ext4_mb_init_cache return error

ext4_mb_init_cache() incorrectly always return EIO on success. This
causes the caller of ext4_mb_init_cache() fail when it checks the return
value.

Subject: [PATCH 338/794] ext4: fix error processing in mb_free_blocks

The error processing of the return value of mb_free_blocks is meanless
because it only returns 0.  This fix includes

- make mb_free_blocks return void

- remove the error processing part in callers

- unlock group before calling ext4_error in mb_free_blocks

Subject: [PATCH 340/794] jbd2: Add commit time into the commit block

Carlo Wood has demonstrated that it's possible to recover deleted
files from the journal.  Something that will make this easier is if we
can put the time of the commit into commit block.

Subject: [PATCH 341/794] ext4: New inode allocation for FLEX_BG meta-data
 groups.

This patch mostly controls the way inode are allocated in order to
make ialloc aware of flex_bg block group grouping.  It achieves this
by bypassing the Orlov allocator when block group meta-data are packed
toghether through mke2fs.  Since the impact on the block allocator is
minimal, this patch should have little or no effect on other block
allocation algorithms. By controlling the inode allocation, it can
basically control where the initial search for new block begins and
thus indirectly manipulate the block allocator.

This allocator favors data and meta-data locality so the disk will
gradually be filled from block group zero upward.  This helps improve
performance by reducing seek time.  Since the group of inode tables
within one flex_bg are treated as one giant inode table, uninitialized
block groups would not need to partially initialize as many inode
table as with Orlov which would help fsck time as the filesystem usage
goes up.

Subject: [PATCH 342/794] jbd2: fix race between
 jbd2_journal_try_to_free_buffers() and jbd2 commit transaction

journal_try_to_free_buffers() could race with jbd commit transaction
when the later is holding the buffer reference while waiting for the
data buffer to flush to disk. If the caller of
journal_try_to_free_buffers() request tries hard to release the buffers,
it will treat the failure as error and return back to the caller. We
have seen the directo IO failed due to this race.  Some of the caller of
releasepage() also expecting the buffer to be dropped when passed with
GFP_KERNEL mask to the releasepage()->journal_try_to_free_buffers().

With this patch, if the caller is passing the GFP_KERNEL to indicating
this call could wait, in case of try_to_free_buffers() failed, let's
waiting for journal_commit_transaction() to finish commit the current
committing transaction , then try to free those buffers again with
journal locked.

Subject: [PATCH 345/794] ext4: Update i_disksize properly when allocating from
 fallocate area.

When allocating unitialized space at the end of file which had been
preallocated with the FALLOC_FL_KEEP_SIZE option, the file size is not
updated at that time.  But the later we are not updating the file size
when writing to that preallocated space.

These changes are for code correctness.  This patch allows us to update
the i_disksize at the write_end() callback of filesystem properly.

Subject: [PATCH 351/794] ext4: fix ext4_init_block_bitmap() for metablock
 block group

When meta_bg feature is enabled and s_first_meta_bg != 0,
ext4_init_block_bitmap() miscalculates the number of block used by
the group descriptor table (0 or 1 for metablock block group)

This patch fixes this by using ext4_bg_num_gdb()

Subject: [PATCH 352/794] ext4: Use inode preallocation with -o noextents

When mballoc is enabled, block allocation for old block-based
files are allocated using mballoc allocator instead of old
block-based allocator. The old ext3 block reservation is turned
off when mballoc is turned on.

However, the in-core preallocation is not enabled for block-based/
non-extent based file block allocation. This result in performance
regression, as now we don't have "reservation" ore in-core preallocation
to prevent interleaved fragmentation in multiple writes workload.

This patch fix this by enable per inode in-core preallocation
for non extent files when mballoc is used.

Subject: [PATCH 354/794] ext4: call blkdev_issue_flush on fsync

To ensure that bits are truly on-disk after an fsync,
we should call blkdev_issue_flush if barriers are supported.

Inspired by an old thread on barriers, by reiserfs & xfs
which do the same, and by a patch SuSE ships with their kernel

Subject: [PATCH 355/794] ext4: mballoc avoid use root reserved blocks for non
 root allocation

mballoc allocation missed check for blocks reserved for root users. Add
ext4_has_free_blocks() check before allocation. Also modified
ext4_has_free_blocks() to support multiple block allocation request.

Subject: [PATCH 356/794] ext4: Set journal pointer to NULL when journal is
 released

Set sbi->s_journal to NULL after we call journal_destroy(). This
will be later needed because after journal_destroy() is called,
ext4_clear_inode() can still be called for some inodes (e.g. root
inode) and we'll need to detect there that journal doesn't exists
anymore.

 1. Quick usage instructions:
 ===========================
 
-  - Grab updated e2fsprogs from
-    ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs-interim/
-    This is a patchset on top of e2fsprogs-1.39, which can be found at
+  - Compile and install the latest version of e2fsprogs (as of this
+    writing version 1.41) from:
+
+    http://sourceforge.net/project/showfiles.php?group_id=2406
+	
+	or
+
     ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/
 
-  - It's still mke2fs -j /dev/hda1
+	or grab the latest git repository from:
+
+    git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git
+
+  - Create a new filesystem using the ext4dev filesystem type:
+
+    	# mke2fs -t ext4dev /dev/hda1
+
+    Or configure an existing ext3 filesystem to support extents and set
+    the test_fs flag to indicate that it's ok for an in-development
+    filesystem to touch this filesystem:
 
-  - mount /dev/hda1 /wherever -t ext4dev
+	# tune2fs -O extents -E test_fs /dev/hda1
 
-  - To enable extents,
+    If the filesystem was created with 128 byte inodes, it can be
+    converted to use 256 byte for greater efficiency via:
 
-	mount /dev/hda1 /wherever -t ext4dev -o extents
+        # tune2fs -I 256 /dev/hda1
 
-  - The filesystem is compatible with the ext3 driver until you add a file
-    which has extents (ie: `mount -o extents', then create a file).
+    (Note: we currently do not have tools to convert an ext4dev
+    filesystem back to ext3; so please do not do try this on production
+    filesystems.)
 
-    NOTE: The "extents" mount flag is temporary.  It will soon go away and
-    extents will be enabled by the "-o extents" flag to mke2fs or tune2fs
+  - Mounting:
+
+	# mount -t ext4dev /dev/hda1 /wherever
 
   - When comparing performance with other filesystems, remember that
-    ext3/4 by default offers higher data integrity guarantees than most.  So
-    when comparing with a metadata-only journalling filesystem, use `mount -o
-    data=writeback'.  And you might as well use `mount -o nobh' too along
-    with it.  Making the journal larger than the mke2fs default often helps
-    performance with metadata-intensive workloads.

 2. Features
 ===========
 
 2.1 Currently available
 
-* ability to use filesystems > 16TB
+* ability to use filesystems > 16TB (e2fsprogs support not available yet)
 * extent format reduces metadata overhead (RAM, IO for access, transactions)
 * extent format more robust in face of on-disk corruption due to magics,
 * internal redunancy in tree
-
-2.1 Previously available, soon to be enabled by default by "mkefs.ext4":
-
-* dir_index and resize inode will be on by default
-* large inodes will be used by default for fast EAs, nsec timestamps, etc
+* improved file allocation (multi-block alloc, delayed alloc)
+* fix 32000 subdirectory limit
+* nsec timestamps for mtime, atime, ctime, create time
+* inode version field on disk (NFSv4, Lustre)
+* reduced e2fsck time via uninit_bg feature
+* journal checksumming for robustness, performance
+* persistent file preallocation (e.g for streaming media, databases)
+* ability to pack bitmaps and inode tables into larger virtual groups via the
+  flex_bg feature
+* large file support
+* Inode allocation using large virtual block groups via flex_bg
 
 2.2 Candidate features for future inclusion
 
-There are several under discussion, whether they all make it in is
-partly a function of how much time everyone has to work on them:
+* Online defrag (patches available but not well tested)
+* reduced mke2fs time via lazy itable initialization in conjuction with
+  the uninit_bg feature (capability to do this is available in e2fsprogs
+  but a kernel thread to do lazy zeroing of unused inode table blocks
+  after filesystem is first mounted is required for safety)
 
-* improved file allocation (multi-block alloc, delayed alloc; basically done)
-* fix 32000 subdirectory limit (patch exists, needs some e2fsck work)
-* nsec timestamps for mtime, atime, ctime, create time (patch exists,
-  needs some e2fsck work)
-* inode version field on disk (NFSv4, Lustre; prototype exists)
-* reduced mke2fs/e2fsck time via uninitialized groups (prototype exists)
-* journal checksumming for robustness, performance (prototype exists)
-* persistent file preallocation (e.g for streaming media, databases)
+There are several others under discussion, whether they all make it in is
+partly a function of how much time everyone has to work on them. Features like
+metadata checksumming have been discussed and planned for a bit but no patches
+exist yet so I'm not sure they're in the near-term roadmap.
 
-Features like metadata checksumming have been discussed and planned for

+The big performance win will come with mballoc, delalloc and flex_bg

-The big performance win will come with mballoc and delalloc.  CFS has
-been using mballoc for a few years already with Lustre, and IBM + Bull

-patches is partly a manageability issue, and partly because it doesn't
-directly affect the on-disk format (outside of much better allocation)
-so it isn't critical to get into the first round of changes.  I believe
-Alex is working on a new set of patches right now.

Subject: [PATCH 360/794] ext4: Use page_mkwrite vma_operations to get mmap
 write notification.

We would like to get notified when we are doing a write on mmap section.
This is needed with respect to preallocated area. We split the preallocated
area into initialzed extent and uninitialzed extent in the call back. This
let us handle ENOSPC better. Otherwise we get ENOSPC in the writepage and
that would result in data loss. The changes are also needed to handle ENOSPC
when writing to an mmap section of files with holes.

Subject: [PATCH 361/794] vfs: Move mark_inode_dirty() from under page lock in
 generic_write_end()

There's no need to call mark_inode_dirty() under page lock in
generic_write_end(). It unnecessarily makes hold time of page lock longer
and more importantly it forces locking order of page lock and transaction
start for journaling filesystems.

Subject: [PATCH 362/794] ext4: Invert the locking order of page_lock and
 transaction start

This changes are needed to support data=ordered mode handling via
inodes.  This enables us to get rid of the journal heads and buffer
heads for data buffers in the ordered mode.  With the changes, during
tranasaction commit we writeout the inode pages using the
writepages()/writepage(). That implies we take page lock during
transaction commit. This can cause a deadlock with the locking order
page_lock -> jbd2_journal_start, since the jbd2_journal_start can wait
for the journal_commit to happen and the journal_commit now needs to
take the page lock. To avoid this dead lock reverse the locking order.

We cannot call ext4_orphan_add() from under i_data_sem because that
causes a lock ordering violation between i_data_sem and and the
superblock lock.

Updated with Aneesh's locking order fix

Subject: [PATCH 365/794] jbd2: Implement data=ordered mode handling via inodes

This patch adds necessary framework into JBD2 to be able to track inodes
with each transaction and write-out their dirty data during transaction
commit time.

This new ordered mode brings all sorts of advantages such as possibility
to get rid of journal heads and buffer heads for data buffers in ordered
mode, better ordering of writes on transaction commit, simplification of
 some JBD code, no more anonymous pages when truncate of data being
committed happens.  Also with this new ordered mode, delayed allocation
on ordered mode is much simpler.

Subject: [PATCH 366/794] ext4: Use new framework for data=ordered mode in JBD2

This patch makes ext4 use inode-based implementation of data=ordered mode
in JBD2. It allows us to unify some data=ordered and data=writeback paths
(especially writepage since we don't have to start a transaction anymore)
and remove some buffer walking.

Updated fix from Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
to fix file system hang due to corrupt jinode values.

Subject: [PATCH 368/794] vfs: add hooks for ext4's delayed allocation support

Export mpage_bio_submit() and __mpage_writepage() for the benefit of
ext4's delayed allocation support.   Also change __block_write_full_page
so that if buffers that have the BH_Delay flag set it will call
get_block() to get the physical block allocated, just as in the
!BH_Mapped case.

Subject: [PATCH 369/794] ext4: Add delayed allocation support in
 data=writeback mode

Updated with fixes from Mingming Cao <cmm@us.ibm.com> to unlock and
release the page from page cache if the delalloc write_begin failed, and
properly handle preallocated blocks.  Also added a fix to clear
buffer_delay in block_write_full_page() after allocating a delayed
buffer.

Updated with fixes from Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
to update i_disksize properly and to add bmap support for delayed
allocation.

Updated with a fix from Valerie Clement <valerie.clement@bull.net> to
avoid filesystem corruption when the filesystem is mounted with the
delalloc option and blocksize < pagesize.

Subject: [PATCH 370/794] percpu_counter: new function
 percpu_counter_sum_and_set

Delayed allocation need to check free blocks at every write time.
percpu_counter_read_positive() is not quit accurate. delayed
allocation need a more accurate accounting, but using
percpu_counter_sum_positive() is frequently is quite expensive.

This patch added a new function to update center counter when sum
per-cpu counter, to increase the accurate rate for next
percpu_counter_read() and require less calling expensive
percpu_counter_sum().

Subject: [PATCH 371/794] ext4: delayed allocation ENOSPC handling

This patch does block reservation for delayed
allocation, to avoid ENOSPC later at page flush time.

Blocks(data and metadata) are reserved at da_write_begin()
time, the freeblocks counter is updated by then, and the number of
reserved blocks is store in per inode counter.

At the writepage time, the unused reserved meta blocks are returned
back. At unlink/truncate time, reserved blocks are properly released.

Updated fix from  Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
to fix the oldallocator block reservation accounting with delalloc, added
lock to guard the counters and also fix the reservation for meta blocks.

Subject: [PATCH 372/794] mm: Add range_cont mode for writeback

Filesystems like ext4 needs to start a new transaction in
the writepages for block allocation. This happens with delayed
allocation and there is limit to how many credits we can request
from the journal layer. So we call write_cache_pages multiple
times with wbc->nr_to_write set to the maximum possible value
limitted by the max journal credits available.

Add a new mode to writeback that enables us to handle this
behaviour. In the new mode we update the wbc->range_start
to point to the new offset to be written. Next call to
call to write_cache_pages will start writeout from specified
range_start offset. In the new mode we also limit writing
to the specified wbc->range_end.

Subject: [PATCH 373/794] ext4: Invert lock ordering of page_lock and
 transaction start in delalloc

With the reverse locking, we need to start a transation before taking
the page lock, so in ext4_da_writepages() we need to break the write-out
into chunks, and restart the journal for each chunck to ensure the
write-out fits in a single transaction.

Updated patch from Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
which fixes delalloc sync hang with journal lock inversion, and address
the performance regression issue.

Subject: [PATCH 374/794] ext4: Add ordered mode support for delalloc

This provides a new ordered mode implementation which gets rid of using
buffer heads to enforce the ordering between metadata change with the
related data chage.  Instead, in the new ordering mode, it keeps track
of all of the inodes touched by each transaction on a list, and when
that transaction is committed, it flushes all of the dirty pages for
those inodes.  In addition, the new ordered mode reverses the lock
ordering of the page lock and transaction lock, which provides easier
support for delayed allocation.

Subject: [PATCH 375/794] ext4: Handle page without buffers in
 ext4_*_writepage()

It can happen that buffers are removed from the page before it gets
marked dirty and then is passed to writepage().  In writepage() we just
initialize the buffers and check whether they are mapped and non
delay. If they are mapped and non delay we write the page. Otherwise we
mark them dirty.  With this change we don't do block allocation at all
in ext4_*_write_page.

writepage() can get called under many condition and with a locking order
of journal_start -> lock_page, we should not try to allocate blocks in
writepage() which get called after taking page lock.  writepage() can
get called via shrink_page_list even with a journal handle which was
created for doing inode update.  For example when doing
ext4_da_write_begin we create a journal handle with credit 1 expecting a
i_disksize update for the inode. But ext4_da_write_begin can cause
shrink_page_list via _grab_page_cache. So having a valid handle via
ext4_journal_current_handle is not a guarantee that we can use the
handle for block allocation in writepage, since we shouldn't be using
credits that had been reserved for other updates.  That it could result
in we running out of credits when we update inodes.

Subject: [PATCH 376/794] ext4: fix delalloc i_disksize early update issue

Ext4_da_write_end() used walk_page_buffers() with a callback function of
ext4_bh_unmapped_or_delay() to check if it extended the file size
without allocating any blocks (since in this case i_disksize needs to be
updated).  However, this is didn't work proprely because the buffer head
has not been marked dirty yet --- this is done later in
block_commit_write() --- which caused ext4_bh_unmapped_or_delay() to
always return false.

In addition, walk_page_buffers() checks all of the buffer heads covering
the page, and the only buffer_head that should be checked is the one
covering the end of the write.  Otherwise, given a 1k blocksize
filesystem and a 4k page size, the buffer head covering the first 1k
stripe of the file could be unmapped (because it was a sparse file), and
the second or third buffer_head covering that page could be mapped, and
using walk_page_buffers() would fail in this case since it would stop at
the first unmapped buffer_head and return true.

The core problem is that walk_page_buffers() was intended to do work in
a callback function, and a non-zero return value indicated a failure,
which termined the walk of the buffer heads covering the page.  It was
not intended to be used with a boolean function, such as
ext4_bh_unmapped_or_delay().

Add addtional fix from Aneesh to protect i_disksize update rave with truncate.

Subject: [PATCH 377/794] ext4: delayed allocation i_blocks fix for stat

Right now i_blocks is not getting updated until the blocks are actually
allocaed on disk.  This means with delayed allocation, right after files
are copied, "ls -sF" shoes the file as taking 0 blocks on disk.  "du"
also shows the files taking zero space, which is highly confusing to the
user.

Since delayed allocation already keeps track of per-inode total
number of blocks that are subject to delayed allocation, this patch fix
this by using that to adjust the value returned by stat(2). When real
block allocation is done, the i_blocks will get updated. Since the
reserved blocks for delayed allocation will be decreased, this will be
keep value returned by stat(2) consistent.

Subject: [PATCH 378/794] ext4: Enable delalloc by default.

Enable delalloc by default to ensure it gets sufficient testing and
because it makes the filesystem much more efficient.  Add a nodealalloc
option to disable delayed allocation, and update ext4_show_options to
show delayed allocation off if it is disabled.

If the data=journal mount option is used, disable delayed allocation
since the delalloc code doesn't support data=journal yet.

Subject: [PATCH 379/794] ext4: Don't allow nonextenst mount option for large
 filesystem

The block mapped inode format can address only blocks within 2**32. This
causes a number of issues, the biggest of which is that the block
allocator needs to be taught that certain inodes can not utilize block
numbers > 2**32.  So until this is fixed, it is simplest to fail
mounting of file systems with more than 2**32 blocks if the -o noextents
option is given.

Subject: [PATCH 380/794] ext4: do not set extents feature from the kernel

We've talked for a while about getting rid of any feature-
setting from the kernel; this gets rid of the code which would
set the INCOMPAT_EXTENTS flag on the first file write when mounted
as ext4[dev].

With this patch, if the extents feature is not already set on disk,
then mounting as ext4 will fall back to noextents with a warning,
and if -o extents is explicitly requested, the mount will fail,
also with warning.

Subject: [PATCH 385/794] [SCSI] mpt fusion : Adding FAULT Reset polling work

When the firmware is in Fault state it will be identifed only when the next time
the driver access the IOC state.
This patch includes a polling function in the driver which will be executed in
regular interval to check the status of the firmware and if it is in Fault
state, then the firmware will be reset by the driver.

Subject: [PATCH 386/794] [SCSI] iscsi class, iscsi_tcp/iser: add host arg to
 session creation

iscsi offload (bnx2i and qla4xx) allocate a scsi host per hba,
so the session creation path needs a shost/host_no argument.
Software iscsi/iser will follow the same behabior as before
where it allcoates a host per session, but in the future iser
will probably look more like bnx2i where the host's parent is
the hardware (rnic for iser and for bnx2i it is the nic), because
it does not use a socket layer like how iscsi_tcp does.

max_cmd_len and max_conn are not really used. max_cmd_len is
always 16 and can be set by the LLD. max_conn is always one
since we do not support MCS.

This renames the iscsi_host to iscsi_cls_host to match the other
structs, because libiscsi wants to use the iscsi_host name in
the future.

Subject: [PATCH 389/794] [SCSI] iscsi: remove session and host binding in
 libiscsi

bnx2i allocates a host per netdevice but will use libiscsi,
so this unbinds the session from the host in that code.

This will also be useful for the iser parent device dma settings
fixes.

Subject: [PATCH 391/794] [SCSI] iscsi: remove session/conn_data_size from
 iscsi_transport

This removes the session and conn data_size fields from the iscsi_transport.
Just pass in the value like with host allocation. This patch also makes
it so the LLD iscsi_conn data is allocated with the iscsi_cls_conn.

Subject: [PATCH 392/794] [SCSI] iscsi: modify iscsi printk so it can take
 driver data pointers

Some drivers want to be able to just pass in the driver data pointers
to the iscsi objects. To enable this we need the iscsi printk macro
to cast the object.

Subject: [PATCH 393/794] [SCSI] iser: fix handling of scsi cmnds during
 recovery.

After the stop_conn callback has returned the LLD should not
touch the scsi cmds. iscsi_tcp and libiscsi use the
conn->recv_lock and suspend_rx field to halt recv path
processing, but iser does not have any protection.

This patch modifies iser so that userspace can just
call the ep_disconnect callback, which will halt
all recv IO, before calling the stop_conn callback so
we do not have to worry about the conn->recv_lock and
suspend rx field. iser just needs to stop the send side
from accessing the ib conn.

Fixup to handle when the ep poll fails and ep disconnect
is called from Erez.

Subject: [PATCH 394/794] [SCSI] libiscsi, iscsi_tcp, iser: add session cmds
 array accessor

Currently to get a ctask from the session cmd array, you have to
know to use the itt modifier. To make this easier on LLDs and
so in the future we can easilly kill the session array and use
the host shared map instead, this patch adds a nice wrapper
to strip the itt into a session->cmds index and return a ctask.

From 052d014485d2ce5bb7fa8dd0df875dafd1db77df Mon Sep 17 00:00:00 2001
From: Mike Christie <michaelc@cs.wisc.edu>
Date: Wed, 21 May 2008 15:54:05 -0500
Subject: [PATCH 395/794] [SCSI] libiscsi: modify libiscsi so it supports
 offloaded data paths

This patch modifies libiscsi, so drivers like bnx2i and iser can execute
a command from queuecommand/send_pdu instead of having to be queued to
be run in a workq.

Subject: [PATCH 396/794] [SCSI] libiscsi: merge iscsi_mgmt_task and
 iscsi_cmd_task

There is no need to have the mgmt and cmd tasks separate
structs. It used to save a lot of memory when we overprealocated
memory for tasks, but the next patches will set up the
driver so in the future they can use a mempool or some other
common scsi command allocator and common tagging.

Subject: [PATCH 399/794] [SCSI] libiscsi: rename iscsi_cmd_task to iscsi_task

This is the second part of the iscsi task merging, and
all it does it rename iscsi_cmd_task to iscsi_task and
mtask/ctask to just task.

From 7970634b81a6e3561954517bca42615542c4535b Mon Sep 17 00:00:00 2001
From: Mike Christie <michaelc@cs.wisc.edu>
Date: Wed, 21 May 2008 15:54:12 -0500
Subject: [PATCH 402/794] [SCSI] iscsi class: user device_for_each_child
 instead of duplicating session list

Currently we duplicate the list of sessions, because we were using the
test for if a session was on the host list to indicate if the session
was bound or unbound. We can instead use the target_id and fix up
the class so that drivers like bnx2i do not have to manage the target id
space.

From d82ff9be733a2e6da4f6c2ab4e9216f3f536503d Mon Sep 17 00:00:00 2001
From: Mike Christie <michaelc@cs.wisc.edu>
Date: Wed, 21 May 2008 15:54:13 -0500
Subject: [PATCH 403/794] [SCSI] iscsi class: add endpoint class

Add sysfs representation for the endpoint, so userspace can match the
host and session to the endpoint. This will allow us to set the host's
parent correctly at host creation time.

The next patches will convert tcp and iser, and fix iser's dma_mask
bug.

Subject: [PATCH 404/794] [SCSI] iser: Modify iser to take a iscsi_endpoint
 struct in ep callouts and session setup

This hooks iser into the iscsi endpoint code. Previously it handled the
lookup and allocation. This has been made generic so bnx2i and iser can
share it. It also allows us to pass iser the leading conn's ep, so we
know the ib_deivce being used and can set it as the scsi_host's parent.
And that allows scsi-ml to set the dma_mask based on those values.

Subject: [PATCH 405/794] [SCSI] iscsi_tcp: hook iscsi_tcp into iscsi_endpoint

iscsi_tcp creates its ep in userspace using sockets because
it is virtual, so we just check if we are sent a ep and fail
if we are.

Subject: [PATCH 406/794] [SCSI] iscsi class: Add session initiatorname and
 ifacename sysfs attrs.

This adds two new attrs used for creating initiator ports and
binding sessions to hardware.

The session level initiatorname:

Since bnx2i does a scsi_host per host device, we need to add the
iface initiator port settings on the session, so we can create
multiple initiator ports (each with different inames) per device/scsi_host.

The current iname reflects that qla4xxx can have one iname per hba, and we are
allocating a host per session for software. The iname on the host will
remain so we can export and set the hba level qla4xxx setting.

The ifacename attr:

To bind a session to a some peice of hardware in userspace we maintain
some mappings, but during boot or iscsid restart (iscsid contains the user
space part of the driver) we need to be able to figure out which of those
host mappings abstractions maps to certain sessions. This patch adds
a ifacename attr, which userspace can set to id the host side of the
endpoint across pivot_roots and iscsid restarts.

Subject: [PATCH 407/794] [SCSI] libiscsi: fix cmds_max setting

Drivers expect that the cmds_max value they pass to the iscsi layer
is the max scsi commands  + mgmt tasks. This patch implements that
and fixes some checks for nr cmd limits.

Subject: [PATCH 408/794] [SCSI] libiscsi, iser, tcp: remove recv_lock

The recv lock was defined so the iscsi layer could block
the recv path from processing IO during recovery. It
turns out iser just set a lock to that pointer which was pointless.

We now disconnect the transport connection before doing recovery
so we do not need the recv lock. For iscsi_tcp we still stop
the recv path incase older tools are being used.

This patch also has iscsi_itt_to_ctask user grab the session lock
and has the caller access the task with the lock or get a ref
to it in case the target is broken and sends a tmf success response
then sends data or a response for the command that was supposed to
be affected bty the tmf.

Subject: [PATCH 412/794] [SCSI] bsg: fix bsg_mutex hang with device removal

We don't need to hold bsg_mutex during bsg_complete_all_commands(). It
leads to a problem that we block bsg_unregister_queue during
bsg_complete_all_commands (untill all the outstanding commands
complete).

Thanks to Pete Wyckoff for finding the bug and testing the patch.

The detailed bug report is:

Subject: [PATCH 413/794] [SCSI] scsi_debug: Runtime-configurable sector size

Make scsi_debug sector size configurable at load time instead of being
a #define.  Handy for testing 4KB sectors.

Subject: [PATCH 414/794] [SCSI] aacraid: prevent copy_from_user() BUG!

Seen:

	kernel BUG at arch/i386/lib/usercopy.c:872

under a 2.6.18-8.el5 kernel. Traced it to a garbage-in/garbage-out
ioctl condition in the aacraid driver.

Adaptec's special ioctl scb passthrough needs to check the validity of
the individual scatter gather count fields to the maximum the adapter
supports. Doing so will have the side effect of preventing
copy_from_user() from bugging out while populating the dma buffers.
This is a hardening effort, issue was triggered by an errant version
of the management tools and thus the BUG should not be seen in the
field.

From 45633fdc9615f9fd2a0ae18e301562298b15abf3 Mon Sep 17 00:00:00 2001
From: Christof Schmitt <christof.schmitt@de.ibm.com>

Subject: [PATCH 417/794] [SCSI] zfcp: Move CFDC code to new file.

zfcp implements a device file to allow Linux guests changing the
Access Control Tables stored in the adapter. The code for the device
file has nothing to do with the other parts of the driver, so move it
to a new file and cleanup the code while doing so.

From 553448f6c4838a1e4bed2bc9301c748278d7d9ce Mon Sep 17 00:00:00 2001
From: Christof Schmitt <christof.schmitt@de.ibm.com>
Date: Tue, 10 Jun 2008 18:20:58 +0200
Subject: [PATCH 420/794] [SCSI] zfcp: Message cleanup

Cleanup the messages used in the zfcp driver: Remove unnecessary debug
and trace message and convert the remaining messages to standard
kernel macros. Remove the zfcp message macros and while updating the
whole flie also update the copyright headers.

Subject: [PATCH 421/794] [SCSI] zfcp: Add port_state attribute to sysfs

The sysfs attribute /sys/class/fc_host/hostX/port_state was not set by
zfcp so far.

Now, the appropriate members of the fc_function_template struct are
set during its initialziation. The first is a boolean to show the port
state. The second is a function pointer to the function
zfcp_get_host_port_state, which reads the port state from our adapter
status bits and calls fc_host_port_state with the approriate port
state afterwards.

Subject: [PATCH 422/794] [SCSI] zfcp: Automatically attach remote ports

Automatically attach the remote ports in zfcp when the adapter is set
online. This is done by querying all available ports from the FC
namesever. The scan for remote ports is also triggered by RSCNs and
can be triggered manually with the sysfs attribute 'port_rescan'.

Subject: [PATCH 423/794] [SCSI] zfcp: Remove sysfs attribute port_add

With the automatic scanning of remote ports in place, there is no need
to add remote ports manually. So, remove the port_add attribute.

Subject: [PATCH 424/794] [SCSI] lpfc 8.2.7 : Change device reset behavior

Prior handler was only waiting for I/O on one lun to finish before
returning completion. Now, wait for all LUNs on the target.
Also performed some rudimentary cleanup while in this code.

Subject: [PATCH 425/794] [SCSI] lpfc 8.2.7 : Discovery Fixes

- Fix ADISC timeout on initiators causing devloss timeout on targets
- Correct FAN processing : port state vs unreg rpi's wasn't consistent
- Correct mismatches between ASICs and PLOGI that would skip PLOGI

From 5e9d9b8276980fc5dfa88ce34f6ec88ce3026232 Mon Sep 17 00:00:00 2001
From: James Smart <James.Smart@Emulex.Com>
Date: Sat, 14 Jun 2008 22:52:53 -0400
Subject: [PATCH 426/794] [SCSI] lpfc 8.2.7 : Rework the worker thread

Rework of the worker thread to make it more efficient.
Make a finer-grain notfication of pending work so less time is
spent checking conditions. Also made other general cleanups.

Subject: [PATCH 427/794] [SCSI] lpfc 8.2.7 : Miscellaneous Fixes

Miscellaneous Fixes:
- Fix bug in mbox sysfs interface that locked in EAGAIN if discovery stalled.
- Fix missing error message when npiv and loop are true when link up occurs.
- Fix panic in lpfc_scsi_cmd_iocb_cmpl: scsi_buf was NULL, but created
  race conditions with other code paths.
- Fix error in sysfs mailbox structure that didn't rezero on next use.
- Add missing mempool_free() to attachment failure path
- Fix missing put of ndlp structure during driver unload.
- Fix applications unable to send mailbox commands during discovery.
- Remove unused argument (type) from function lpfc_post_buffer() API
- Fix vport name is not shown after hbacmd vportcreate.
- Remove repeated code statements.

Subject: [PATCH 430/794] [SCSI] libiscsi, iscsi_tcp, ib_iser: fix setting of
 can_queue with old tools.

This patch fixes two bugs that are related.

1. Old tools did not set can_queue/cmds_max. This patch modifies
libiscsi so that when we add the host we catch this and set it
to the default.

2. iscsi_tcp thought that the scsi command that was passed to
the eh functions needed a iscsi_cmd_task allocated for it. It
only needed a mgmt task, and now it does not matter since it
all comes from the same pool and libiscsi handles this for the
drivers. ib_iser had copied iscsi_tcp's code and set can_queue
to its max - 1 to handle this. So this patch removes the max -1,
and just sets it to the max.

about a remove racing with the callers access, so we can simplify the
use and drop the ref right away.

Subject: [PATCH 440/794] [SCSI] ibmvfc: IBM Power Virtual Fibre Channel
 Adapter Client Driver

This patch adds a new device driver to support the Virtual Fibre Channel
interface on IBM Power based servers. The Virtual I/O Server on IBM Power
servers utilizes N-Port ID Virtualization to export a Virtual Fibre Channel
adapter to the client. This driver is the client device driver.

Subject: [PATCH 441/794] [SCSI] zfcp: wait until adapter is finished with ERP
 during auto-port

In some situations the auto port attachment task is started
before the ERP is finished. To prevent this unwanted situation
we wait until the adapter is up and running before we start our work.

When zfcp receives 16 unsolicited status messages, this could trigger
an adapter reopen. In this case, first try to send a new status read,
and only if this fails, go through the recovery.

From 60221920706a01bef89af2577f9a90a8eeb4e662 Mon Sep 17 00:00:00 2001
From: Swen Schillig <swen@vnet.ibm.com>
Date: Wed, 2 Jul 2008 10:56:38 +0200
Subject: [PATCH 448/794] [SCSI] zfcp: consolidate sysfs things into one file.

zfcp was using three files to deal with sysfs representation
for adapters, ports and units. The consolidation into one file
prevents code-duplication and eases maintainability.

Subject: [PATCH 452/794] [SCSI] fix locking in host use of blk_plug_device()

scsi_lib.c:scsi_host_queue_ready() plugs the device with incorrect
locking.  It should actually have the queue lock held, but it's
holding the host lock.  Fix this by eliminating the call.  The host
ready has no need to plug the queue because if it returns 0 in
scsi_request_function control transfers to not_ready which acquires
the queue lock and plugs the device if its at zero depth.

 re-implementation of container_of

The sym53c8xx driver, for some reason, seems to mostly re-implement
linux/list.h with added bogosity. The main one is it's implementation
of sym_que_entry which spits warnings with recent gcc's on some
64 bits architectures.

Subject: [PATCH 456/794] powerpc/mpc5200: PCI write combine timer

On MPC5200 the PCI target control register (PCITCR) @ MBAR + 0xD6C is
initialized with only bit 7 (Latrule disable) set. The 8-Bit write
combine timer (Bits 24..31) should be also set to a reasonable value
_greater zero_ (0x08 = default) since setting it to 0x00 leads to
_very poor_ performance as a PCI target since external burst won't be
possible at all.

Setting the WCT to 0x08 (cache-line size) leads to good overall perfomance.

Subject: [PATCH 465/794] powerpc/mpc5121: Update device tree for MPC5121ADS
 evaluation board

Current device tree is only bare bones.  This patch adds nodes to make
it a complete tree for the MPC5121ads.

Added nodes include:
    mbx      - opengl coprocessor
    nfc      - nand flash controller
    cpld-pic - on board cpld
    rtc
    clock    - clock control
    pmc      - power management control
    gpio
    mscan    - can module
    i2c
    axe      - audio coprocessor
    display  - display interface unit
    mdio
    ethernet
    usb
    ioctl    - pin config
    pata
    ac97     - PSC configured as AC97
    pscfifo  - psc fifo configuration
    dma
    pci

Fix typo in header changing MDS to ADS.

Add a compatible property of the form "fsl,mpc5121-..."
to nodes missing one.

Changed localbus compatible to fsl,mpc5121-localbus, this does
not break anything because the only code that uses it finds it
via the node name, not compatible.

From 137e95906e294913fab02162e8a1948ade49acb5 Mon Sep 17 00:00:00 2001
From: John Rigby <jrigby@freescale.com>
Date: Wed, 9 Jul 2008 14:54:02 -0600
Subject: [PATCH 466/794] powerpc/mpc5121: Add clock driver

Plugs into the generic powerpc clock driver in
arch/powerpc/kernel/clock.c

The following subset of clk_interface is implemented:
    clk_get, clk_put:  get clock via name, release clock
    clk_enable, clk_disable:  enable or disable clock
    clk_get_rate:  get clock rate in Hz
    clk_set_rate:  stubbed
    clk_round_rate:  stubbed
    clk_set_parent: NULL
    clk_get_parent: NULL

From fb1803224ea145e3424d6295d4aaa8e9fef70642 Mon Sep 17 00:00:00 2001
From: John Rigby <jrigby@freescale.com>
Date: Wed, 9 Jul 2008 14:54:03 -0600
Subject: [PATCH 467/794] powerpc/mpc5121: Add generic board support for
 MPC5121 platforms

Move shared code from mpc5121_ads.c to new file mpc512x_shared.c
- mpc512x_find_ips_freq -> unchanged
- contents of mpc5121_ads_init_IRQ -> mpc512x_init_IRQ
  - looking for fsl,mpc5121-ipic instead of fsl,ipic
- mpc5121_ads_declare_of_platform_devices -> mpc5121_declare_of_platform_devices
  - and use compatible for lookup instead of node name

Add new generic board setup mpc5121_generic.c

Subject: [PATCH 468/794] powerpc/mpc5121: Add support for CPLD on MPC5121ADS
 board

Add a interrupt host for the interrupt controller in the mpc5121ads cpld.
PCI interrupts are 0-7 the rest are 8-15 Touchscreen pendown irq is
hardwired to irq1 All other irqs are chained to irq0

Subject: [PATCH 470/794] rcu classic: update qlen when cpu offline

When callbacks are moved from offline cpu to this cpu,
the qlen field of this rdp should be updated.

[ Paul E. McKenney: ]

The effect of this bug would be for force_quiescent_state() to be invoked
when it should not and vice versa -- wasting cycles in the first case
and letting RCU callbacks remain piled up in the second case.  The bug
is thus "benign" in that it does not result in premature grace-period
termination, but should of course be fixed nonetheless.

Preemption is disabled by the caller's get_cpu_var(), so we are guaranteed
to remain on the same CPU, as required.  The local_irq_disable() is indeed
needed, otherwise, an interrupt might invoke call_rcu() or call_rcu_bh(),
which could cause that interrupt's increment of ->qlen to be lost.

Subject: [PATCH 471/794] scsi: sd: optionally set power condition in START
 STOP UNIT

Adds a new scsi_device flag, start_stop_pwr_cond:  If enabled, the sd
driver will not send plain START STOP UNIT commands but ones with the
power condition field set to 3 (standby) or 1 (active) respectively.

Some FireWire disk firmwares do not stop the motor if power condition is
zero.  Or worse, they become unresponsive after a START STOP UNIT with
power condition = 0 and start = 0.

http://lkml.org/lkml/2008/4/29/704

This patch only adds the necessary code to sd_mod but doesn't activate
it.  Follow-up patches to the FireWire drivers will add detection of
affected devices and enable the code for them.

I did not add power condition values to scsi_error.c::scsi_eh_try_stu()
for now.  The three firmwares which suffer from above mentioned problems
do not need START STOP UNIT in the error handler, and they are not
adversely affected by START STOP UNIT with power condition = 0 and start
= 1 (like scsi_eh_try_stu() sends it if scsi_device.allow_restart is
enabled).

Subject: [PATCH 472/794] firewire: fw-sbp2: fix spindown for PL-3507 and
 TSB42AA9 firmwares

Reported by Tino Keitel:  PL-3507 with firmware from Prolific does not
spin down the disk on START STOP UNIT with power condition = 0 and start
= 0.  It does however work with power condition = 2 or 3.

Also found while investigating this:  DViCO Momobay CX-1 and FX-3A (TI
TSB42AA9/A based) become unresponsive after START STOP UNIT with power
condition = 0 and start = 0.  They stay responsive if power condition is
set when stopping the motor.

This instructs sd_mod to send START STOP UNIT on suspend and resume,
and on driver unbinding or unloading (including when the system is shut
down).

We don't do this though if multiple initiators may log in to the target.

Subject: [PATCH 479/794] ieee1394: dump mmapped iso buffers in core files

Currently, core files do not contain the mmapped memory of the video1394
or dv1394 devices, which contain the actual video input, making it
impossible to analyse the cause of abnormal program termination for
image analysis or (de)compression software.  Fix that.

Signed-off-by: Philippe De Muyter <phdm@macqel.be>

Also affects users of the rawiso ioctl API of raw1394.

Subject: [PATCH 483/794] firewire: clean up fw_card reference counting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is a functionally equivalent replacement of the current reference
counting of struct fw_card instances.  It only converts it to common
idioms as suggested by Kristian Høgsberg:
  - struct kref replaces atomic_t as the counter.
  - wait_for_completion is used to wait for all card users to complete.

BTW, it may make sense to count card->flush_timer and card->work as
card users too.

Subject: [PATCH 484/794] firewire: don't respond to broadcast write requests

Contrary to a comment in the source, request->ack of a broadcast write
request can be ACK_PENDING.  Hence the existing check is insufficient.

Debug dmesg before:
AR spd 0 tl 00, ffc0 -> ffff, ack_pending , QW req, fffff0000234 = ffffffff
AT spd 0 tl 00, ffff -> ffc0, ack_complete, W resp
And the requesting node (linux1394) reports an unsolicited response.

Debug dmesg after:
AR spd 0 tl 00, ffc0 -> ffff, ack_pending , QW req, fffff0000234 = ffffffff

Subject: [PATCH 486/794] cpm_uart: Fix cpm uart corruption with PREEMPT_RT

Fix CPM serial port corruption when running with CONFIG_PREEMPT_RT.
Userland usage of console, and kernel printf's were stepping on each others toes.
Also only take lock if not in an oops.

Subject: [PATCH 488/794] powerpc/86xx: mpc8610_hpcd: fix interrupt trigger
 type for ULi IDE

i8259 PIC is disabled on MPC8610HPCD, and ULi IDE is configured to use
PCI sideband interrupt that is specified in the device tree.

Current HPCD's device tree specify that IDE interrupt is low to high
sensitive, but in practice ULi IDE throws active-high interrupts (not
active-low as all normal PCI devices).

udbg_putc is a *function pointer* that is initialized during
udbg_init_cpm. It might not be initialized properly when called from
udbg_putc_cpm(), so (recursively) call udbg_putc_cpm() directly.

Subject: [PATCH 493/794] cpm_uart: Support uart_wait_until_sent()

Set port->fifosize to the software FIFO size, and update the port timeout
when the baud rate is modified. SCC ports have an optional 32 byte hardware
FIFO which is currently not taken into account, as there is no documented way
to check when the FIFO becomes empty.

Subject: [PATCH 494/794] powerpc/CPM: Add i2c pins to dts and board setup

Initialize I2C pins on boards with CPM1/CPM2 controllers and document the
i2c bus in booting-without-of.

The boards don't have any I2C chips connected to the I2C bus, so unless
some external chips are connected to the boards, this code is just an
example of setting everything else up.

+   The I2C controller is expressed as a bus under the CPM node.
+
+   Properties:
+   - compatible : "fsl,cpm1-i2c", "fsl,cpm2-i2c"
+   - reg : On CPM2 devices, the second resource doesn't specify the I2C
+     Parameter RAM itself, but the I2C_BASE field of the CPM2 Parameter RAM
+     (typically 0x8afc 0x2).
+   - #address-cells : Should be one. The cell is the i2c device address with
+     the r/w bit set to zero.
+   - #size-cells : Should be zero.
+   - clock-frequency : Can be used to set the i2c clock frequency. If
+     unspecified, a default frequency of 60kHz is being used.
+   The following two properties are deprecated. They are only used by legacy
+   i2c drivers to find the bus to probe:
+   - linux,i2c-index : Can be used to hard code an i2c bus number. By default,
+     the bus number is dynamically assigned by the i2c core.
+   - linux,i2c-class : Can be used to override the i2c class. The class is used
+     by legacy i2c device drivers to find a bus in a specific context like
+     system management, video or sound. By default, I2C_CLASS_HWMON (1) is
+     being used. The definition of the classes can be found in
+     include/i2c/i2c.h
+
+   Example, based on mpc823:
+
+	i2c@860 {
+		compatible = "fsl,mpc823-i2c",

Subject: [PATCH 496/794] powerpc/booke: don't reinitialize time base

For some reason long ago I decided that we should zero out the time base
when we calibrate the decrementer.  The problem is that this can be
harmful in SMP systems where the firmware has already synchronized the
time bases on the various cores.

Subject: [PATCH 498/794] powerpc: Add 82xx/83xx/86xx to 6xx Multiplatform

There isn't any reason at this point that we can't build 82xx, 83xx & 86xx
support in with the other 6xx based boards.  Twiddle the Kconfigs to allow
this.

This allows us to remove the machine type selection for related to 6xx.

-     driver should use "Soft-UART" mode, which is needed on some SOCs that have
-     broken UART hardware.  Soft-UART is provided via a microcode upload.

-   v) Parallel I/O Ports
-
-   This node configures Parallel I/O ports for CPUs with QE support.
-   The node should reside in the "soc" node of the tree.  For each
-   device that using parallel I/O ports, a child node should be created.
-   See the definition of the Pin configuration nodes below for more
-   information.
-
-   Required properties:
-   - device_type : should be "par_io".
-   - reg : offset to the register set and its length.
-   - num-ports : number of Parallel I/O ports
-
-   Example:
-	par_io@1400 {
-		reg = <1400 100>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-		device_type = "par_io";
-		num-ports = <7>;
-		ucc_pin@01 {
-			......
-		};
-
-   Note that "par_io" nodes are obsolete, and should not be used for
-   the new device trees. Instead, each Par I/O bank should be represented
-   via its own gpio-controller node:
-
-   Required properties:
-   - #gpio-cells : should be "2".
-   - compatible : should be "fsl,<chip>-qe-pario-bank",
-     "fsl,mpc8323-qe-pario-bank".
-   - reg : offset to the register set and its length.
-   - gpio-controller : node to identify gpio controllers.
-
-   Example:
-	qe_pio_a: gpio-controller@1400 {
-		#gpio-cells = <2>;
-		compatible = "fsl,mpc8360-qe-pario-bank",
-			     "fsl,mpc8323-qe-pario-bank";
-		reg = <0x1400 0x18>;
-		gpio-controller;
-	};
-
-	qe_pio_e: gpio-controller@1460 {
-		#gpio-cells = <2>;
-		compatible = "fsl,mpc8360-qe-pario-bank",
-			     "fsl,mpc8323-qe-pario-bank";
-		reg = <0x1460 0x18>;
-		gpio-controller;

-
-   vi) Pin configuration nodes
-
-   Required properties:
-   - linux,phandle : phandle of this node; likely referenced by a QE
-     device.
-   - pio-map : array of pin configurations.  Each pin is defined by 6
-     integers.  The six numbers are respectively: port, pin, dir,
-     open_drain, assignment, has_irq.
-     - port : port number of the pin; 0-6 represent port A-G in UM.
-     - pin : pin number in the port.
-     - dir : direction of the pin, should encode as follows:
-
-	0 = The pin is disabled
-	1 = The pin is an output
-	2 = The pin is an input
-	3 = The pin is I/O
-
-     - open_drain : indicates the pin is normal or wired-OR:
-
-	0 = The pin is actively driven as an output
-	1 = The pin is an open-drain driver. As an output, the pin is
-	    driven active-low, otherwise it is three-stated.
-
-     - assignment : function number of the pin according to the Pin Assignment
-       tables in User Manual.  Each pin can have up to 4 possible functions in
-       QE and two options for CPM.
-     - has_irq : indicates if the pin is used as source of external
-       interrupts.
-
-   Example:
-	ucc_pin@01 {
-		linux,phandle = <140001>;
-		pio-map = <
-		/* port  pin  dir  open_drain  assignment  has_irq */

-				     "fsl,cpm-muram-data";
-			reg = <0 c000>;
-		};
-	};
-
-   viii) Uploaded QE firmware
-
-	 If a new firwmare has been uploaded to the QE (usually by the
-	 boot loader), then a 'firmware' child node should be added to the QE
-	 node.  This node provides information on the uploaded firmware that
-	 device drivers may need.
-
-	 Required properties:
-	 - id: The string name of the firmware.  This is taken from the 'id'
-	       member of the qe_firmware structure of the uploaded firmware.
-	       Device drivers can search this string to determine if the
-	       firmware they want is already present.
-	 - extended-modes: The Extended Modes bitfield, taken from the
-			   firmware binary.  It is a 64-bit number represented
-			   as an array of two 32-bit numbers.
-	 - virtual-traps: The virtual traps, taken from the firmware binary.
-			  It is an array of 8 32-bit numbers.
-
-	 Example:
-
-		firmware {
-			id = "Soft-UART";
-			extended-modes = <0 0>;
-			virtual-traps = <0 0 0 0 0 0 0 0>;

-
-   The global utilities block controls power management, I/O device
-   enabling, power-on-reset configuration monitoring, general-purpose
-   I/O signal configuration, alternate function selection for multiplexed

-      global-utilities.
-    - reg : Offset and length of the register set for the device.
-
-  Recommended properties:
-

-      contains a functioning "reset control register" (i.e. the board
-      is wired to reset upon setting the HRESET_REQ bit in this register).
-
-    Example:
-
-	global-utilities@e0000 {	/* global utilities block */
-		compatible = "fsl,mpc8548-guts";
-		reg = <e0000 1000>;

-   ii) Properties common to mulitple CPM/QE devices
-
-   - fsl,cpm-command : This value is ORed with the opcode and command flag

-
-   - fsl,cpm-brg : Indicates which baud rate generator the device
-                   is associated with.  If absent, an unused BRG
-                   should be dynamically allocated.  If zero, the
-                   device uses an external clock rather than a BRG.
-
-   - reg : Unless otherwise specified, the first resource represents the
-           scc/fcc/ucc registers, and the second represents the device's

-
-   viii) Multi-User RAM (MURAM)
-
-   The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
-
-   Ranges must be set up subject to the following restrictions:
-
-   - Children's reg nodes must be offsets from the start of all muram, even
-     if the user-data area does not begin at zero.
-   - If multiple range entries are used, the difference between the parent
-     address and the child address must be the same in all, so that a single
-     mapping can cover them all while maintaining the ability to determine
-     CPM-side offsets with pointer subtraction.  It is recommended that
-     multiple range entries not be used.
-   - A child address of zero must be translatable, even if no reg resources
-     contain it.
-
-   A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
-   indicate the portion of muram that is usable by the OS for arbitrary
-   purposes.  The data node may have an arbitrary number of reg resources,
-   all of which contribute to the allocatable muram pool.
-
-   Example, based on mpc8272:
-
-	muram@0 {
-		#address-cells = <1>;
-		#size-cells = <1>;
-		ranges = <0 0 10000>;
-
-		data@0 {
-			compatible = "fsl,cpm-muram-data";
-			reg = <0 2000 9800 800>;
-		};
-	};
-
-   x) I2C
-
-   The I2C controller is expressed as a bus under the CPM node.
-
-   Properties:
-   - compatible : "fsl,cpm1-i2c", "fsl,cpm2-i2c"
-   - reg : On CPM2 devices, the second resource doesn't specify the I2C
-     Parameter RAM itself, but the I2C_BASE field of the CPM2 Parameter RAM
-     (typically 0x8afc 0x2).
-   - #address-cells : Should be one. The cell is the i2c device address with
-     the r/w bit set to zero.
-   - #size-cells : Should be zero.
-   - clock-frequency : Can be used to set the i2c clock frequency. If
-     unspecified, a default frequency of 60kHz is being used.
-   The following two properties are deprecated. They are only used by legacy
-   i2c drivers to find the bus to probe:
-   - linux,i2c-index : Can be used to hard code an i2c bus number. By default,
-     the bus number is dynamically assigned by the i2c core.
-   - linux,i2c-class : Can be used to override the i2c class. The class is used
-     by legacy i2c device drivers to find a bus in a specific context like
-     system management, video or sound. By default, I2C_CLASS_HWMON (1) is
-     being used. The definition of the classes can be found in
-     include/i2c/i2c.h
-
-   Example, based on mpc823:
-
-	i2c@860 {
-		compatible = "fsl,mpc823-i2c",
-			     "fsl,cpm1-i2c";
-		reg = <0x860 0x20 0x3c80 0x30>;
-		interrupts = <16>;
-		interrupt-parent = <&CPM_PIC>;
-		fsl,cpm-command = <0x10>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		rtc@68 {
-			compatible = "dallas,ds1307";
-			reg = <0x68>;
-		};
-	};
-
-   m) Chipselect/Local Bus
-
-   Properties:
-   - name : Should be localbus
-   - #address-cells : Should be either two or three.  The first cell is the
-                      chipselect number, and the remaining cells are the
-                      offset into the chipselect.
-   - #size-cells : Either one or two, depending on how large each chipselect
-                   can be.
-   - ranges : Each range corresponds to a single chipselect, and cover
-              the entire access window as configured.
-
-   Example:
-	localbus@f0010100 {
-		compatible = "fsl,mpc8272-localbus",
-		             "fsl,pq2-localbus";
-		#address-cells = <2>;

+Properties:
+- compatible : "fsl,cpm1", "fsl,cpm2", or "fsl,qe".

+
+* Properties common to mulitple CPM/QE devices
+
+- fsl,cpm-command : This value is ORed with the opcode and command flag
+                    to specify the device on which a CPM command operates.
+
+- fsl,cpm-brg : Indicates which baud rate generator the device
+                is associated with.  If absent, an unused BRG
+                should be dynamically allocated.  If zero, the
+                device uses an external clock rather than a BRG.
+
+- reg : Unless otherwise specified, the first resource represents the
+        scc/fcc/ucc registers, and the second represents the device's
+        parameter RAM region (if it has one).
+
+* Multi-User RAM (MURAM)
+
+The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
+
+Ranges must be set up subject to the following restrictions:
+
+- Children's reg nodes must be offsets from the start of all muram, even
+  if the user-data area does not begin at zero.
+- If multiple range entries are used, the difference between the parent
+  address and the child address must be the same in all, so that a single
+  mapping can cover them all while maintaining the ability to determine
+  CPM-side offsets with pointer subtraction.  It is recommended that
+  multiple range entries not be used.
+- A child address of zero must be translatable, even if no reg resources
+  contain it.
+
+A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
+indicate the portion of muram that is usable by the OS for arbitrary
+purposes.  The data node may have an arbitrary number of reg resources,
+all of which contribute to the allocatable muram pool.
+
+Example, based on mpc8272:
+	muram@0 {
+		#address-cells = <1>;

+i2c drivers to find the bus to probe:
+- linux,i2c-index : Can be used to hard code an i2c bus number. By default,

+- linux,i2c-class : Can be used to override the i2c class. The class is used

+* Uploaded QE firmware
+
+      If a new firwmare has been uploaded to the QE (usually by the
+      boot loader), then a 'firmware' child node should be added to the QE
+      node.  This node provides information on the uploaded firmware that
+      device drivers may need.
+
+      Required properties:
+      - id: The string name of the firmware.  This is taken from the 'id'
+            member of the qe_firmware structure of the uploaded firmware.
+            Device drivers can search this string to determine if the
+            firmware they want is already present.
+      - extended-modes: The Extended Modes bitfield, taken from the
+		   firmware binary.  It is a 64-bit number represented
+		   as an array of two 32-bit numbers.
+      - virtual-traps: The virtual traps, taken from the firmware binary.
+		  It is an array of 8 32-bit numbers.
+
+Example:
+	firmware {
+		id = "Soft-UART";
+		extended-modes = <0 0>;
+		virtual-traps = <0 0 0 0 0 0 0 0>;

+* Parallel I/O Ports
+
+This node configures Parallel I/O ports for CPUs with QE support.
+The node should reside in the "soc" node of the tree.  For each
+device that using parallel I/O ports, a child node should be created.
+See the definition of the Pin configuration nodes below for more
+information.
+
+Required properties:
+- device_type : should be "par_io".
+- reg : offset to the register set and its length.
+- num-ports : number of Parallel I/O ports
+
+Example:
+par_io@1400 {

+	#address-cells = <1>;
+	#size-cells = <0>;
+	device_type = "par_io";
+	num-ports = <7>;
+	ucc_pin@01 {
+		......
+	};
+
+Note that "par_io" nodes are obsolete, and should not be used for
+the new device trees. Instead, each Par I/O bank should be represented
+via its own gpio-controller node:
+
+Required properties:
+- #gpio-cells : should be "2".
+- compatible : should be "fsl,<chip>-qe-pario-bank",
+  "fsl,mpc8323-qe-pario-bank".
+- reg : offset to the register set and its length.

+* Pin configuration nodes
+
+Required properties:
+- linux,phandle : phandle of this node; likely referenced by a QE
+  device.
+- pio-map : array of pin configurations.  Each pin is defined by 6
+  integers.  The six numbers are respectively: port, pin, dir,
+  open_drain, assignment, has_irq.
+  - port : port number of the pin; 0-6 represent port A-G in UM.
+  - pin : pin number in the port.
+  - dir : direction of the pin, should encode as follows:
+
+     0 = The pin is disabled
+     1 = The pin is an output
+     2 = The pin is an input
+     3 = The pin is I/O
+
+  - open_drain : indicates the pin is normal or wired-OR:
+
+     0 = The pin is actively driven as an output
+     1 = The pin is an open-drain driver. As an output, the pin is
+         driven active-low, otherwise it is three-stated.
+
+  - assignment : function number of the pin according to the Pin Assignment
+    tables in User Manual.  Each pin can have up to 4 possible functions in
+    QE and two options for CPM.
+  - has_irq : indicates if the pin is used as source of external
+    interrupts.

+- compatible : could be "ucc_geth" or "fsl_atm" and so on.
+- cell-index : the ucc number(1-8), corresponding to UCCx in UM.
+- reg : Offset and length of the register set for the device
+- interrupts : <a b> where a is the interrupt number and b is a
+  field that represents an encoding of the sense and level
+  information for the interrupt.  This should be encoded based on
+  the information in section 2) depending on the type of interrupt
+  controller you have.
+- interrupt-parent : the phandle for the interrupt controller that
+  services interrupts for this device.
+- pio-handle : The phandle for the Parallel I/O port configuration.
+- port-number : for UART drivers, the port number to use, between 0 and 3.
+  This usually corresponds to the /dev/ttyQE device, e.g. <0> = /dev/ttyQE0.
+  The port number is added to the minor number of the device.  Unlike the
+  CPM UART driver, the port-number is required for the QE UART driver.
+- soft-uart : for UART drivers, if specified this means the QE UART device
+  driver should use "Soft-UART" mode, which is needed on some SOCs that have
+  broken UART hardware.  Soft-UART is provided via a microcode upload.
+- rx-clock-name: the UCC receive clock source
+  "none": clock source is disabled
+  "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+  "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+- tx-clock-name: the UCC transmit clock source
+  "none": clock source is disabled
+  "brg1" through "brg16": clock source is BRG1-BRG16, respectively
+  "clk1" through "clk24": clock source is CLK1-CLK24, respectively
+The following two properties are deprecated.  rx-clock has been replaced
+with rx-clock-name, and tx-clock has been replaced with tx-clock-name.
+Drivers that currently use the deprecated properties should continue to
+do so, in order to support older device trees, but they should be updated
+to check for the new properties first.
+- rx-clock : represents the UCC receive clock source.
+  0x00 : clock source is disabled;
+  0x1~0x10 : clock source is BRG1~BRG16 respectively;
+  0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
+- tx-clock: represents the UCC transmit clock source;
+  0x00 : clock source is disabled;
+  0x1~0x10 : clock source is BRG1~BRG16 respectively;
+  0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
+
+Required properties for network device_type:
+- mac-address : list of bytes representing the ethernet address.
+- phy-handle : The phandle for the PHY connected to this controller.

Subject: [PATCH 501/794] powerpc/fsl: update crypto node definition and device
 tree instances

delete obsolete device-type property, delete model property
(use compatible property instead), prepend "fsl," to Freescale
specific properties. Add nodes to device trees that are missing them,
and fix broken property values in other trees.

Today's linux-next build (powerpc allmodconfig) failed like this:

ERROR: ".save_stack_trace" [tests/backtracetest.ko] undefined!

But save_stack_trace is exported in arch/powerpc/kernel/stacktrace.c

I couldn't figure it out until I noticed these earlier warnings:

Subject: [PATCH 505/794] x86, suspend, acpi: enter Big Real Mode

The explanation for recent video BIOS suspend quirk failures is that
the VESA BIOS expects to be entered in Big Real Mode (*.limit = 0xffffffff)
instead of ordinary Real Mode (*.limit = 0xffff).

This patch changes the segment descriptors to Big Real Mode instead.

The segment descriptor registers (what Intel calls "segment cache") is
always active.  The only thing that changes based on CR0.PE is how it is
*loaded* and the interpretation of the CS flags.

The segment descriptor registers contain of the following sub-registers:
selector (the "visible" part), base, limit and flags.  In protected mode
or long mode, they are loaded from descriptors (or fs.base or gs.base can
be manipulated directly in long mode.)  In real mode, the only thing
changed by a segment register load is the selector and the base, where the
base <- selector << 4.  In particular, *the limit and the flags are not
changed*.

As far as the handling of the CS flags: a code segment cannot be writable
in protected mode, whereas it is "just another segment" in real mode, so
there is some kind of quirk that kicks in for this when CR0.PE <- 0.  I'm
not sure if this is accomplished by actually changing the cs.flags register
or just changing the interpretation; it might be something that is
CPU-specific.  In particular, the Transmeta CPUs had an explicit "CS is
writable if you're in real mode" override, so even if you had loaded CS
with an execute-only segment it'd be writable (but not readable!) on return
to real mode.  I'm not at all sure if that is how other CPUs behave.

Subject: [PATCH 507/794] libata: consistently use msecs for time durations

libata has been using mix of jiffies and msecs for time druations.
This is getting confusing.  As writing sub HZ values in jiffies is
PITA and msecs_to_jiffies() can't be used as initializer, unify unit
for all time durations to msecs.  So, durations are in msecs and
deadlines are in jiffies.  ata_deadline() is added to compute deadline
from a start time and duration in msecs.

While at it, drop now superflous _msec suffix from arguments and
rename @timeout to @deadline if it represents a fixed point in time
rather than duration.

From 0a2c0f56159999e20015241d3b8fa89b1ab14309 Mon Sep 17 00:00:00 2001
From: Tejun Heo <htejun@gmail.com>
Date: Tue, 20 May 2008 02:17:52 +0900
Subject: [PATCH 508/794] libata: improve EH retry delay handling

EH retries were delayed by 5 seconds to ensure that resets don't occur
back-to-back.  However, this 5 second delay is superflous or excessive
in many cases.  For example, after IDENTIFY times out, there's no
reason to wait five more seconds before retrying.

This patch adds ehc->last_reset timestamp and record the timestamp for
the last reset trial or success and uses it to space resets by
ATA_EH_RESET_COOL_DOWN which is 5 secs and removes unconditional 5 sec
sleeps.

As this change makes inter-try waits often shorter and they're
redundant in nature, this patch also removes the "retrying..."
messages.

While at it, convert explicit rounding up division to DIV_ROUND_UP().

This change speeds up EH in many cases w/o sacrificing robustness.

Subject: [PATCH 509/794] libata: use ULONG_MAX to terminate reset timeout
 table

This doesn't introduce any functional changes.  This is to make reset
timeout table consistent with to-be-added command timeout tables.

Subject: [PATCH 510/794] libata: improve EH internal command timeout handling

ATA_TMOUT_INTERNAL which was 30secs were used for all internal
commands which is way too long when something goes wrong.  This patch
implements command type based stepped timeouts.  Different command
types can use different timeouts and each command type can use
different timeout values after timeouts.

ie. the initial timeout is set to a value which should cover most of
the cases but not too long so that run away cases don't delay things
too much.  After the first try times out, the second try can use
longer timeout and if that one times out too, it can go for full 30sec
timeout.

IDENTIFYs use 5s - 10s - 30s timeout and all other commands use 5s -
10s timeouts.

This patch significantly cuts down the needed time to handle failure
cases while still allowing libata to work with nut job devices through
retries.

Subject: [PATCH 513/794] libata-eh: update atapi_eh_request_sense() to take
 @dev instead of @qc

Update atapi_eh_request_sense() to take @dev, @sense_buf and
@dfl_sense_key instead of taking @qc and extracting information from
it.  This change is to make the function more generic and allow it to
be called from other places.

While at it, make cdb initialization use initializer.

Subject: [PATCH 516/794] AHCI: speed up resume

During resume, sleep 1 second to wait for the HBA reset
to finish is a waste of time.

According to the AHCI 1.2 spec,
We should poll the HOST_CTL register,
and return error if the host reset is not
finished within 1 second.

Test results show that the HBA reset can be done quickly(in usecs).
And this patch may save nearly 1 second during resume.

Subject: [PATCH 517/794] AHCI: Remove an unnecessary flush from ahci_qc_issue

In an I/O heavy workload (IOZone), ahci_qc_issue is the second-highest
consumer of CPU cycles.  Removing the flush gets us approximately 10%
bandwidth improvement.  I believe this to be because the CPU can start
queueing the next request instead of waiting for the readl() to flush the
writes to the device.  The flush isn't necessary because we're using a
'queue' metaphor; we don't guarantee the command has got to the device,
nor do we need to guarantee the command has got to the controller.

Subject: [PATCH 521/794] i2c-davinci: Remove useless IVR read

Interrupts are enabled at the point where the DAVINCI_I2C_IVR_REG is read,
so unless an interrupt happened just at that moment, no interrupt would be
pending. Even though documentation implies you should do this, I see no
reason. If slave support is added, this read would cause a hard to
reproduce bug.

Subject: [PATCH 524/794] i2c-nforce2: Add support for multiplexing on the Tyan
 S4985

Just like the Tyan S4882, the S4985 uses a multiplexer to give access
to all 16 memory module SPD EEPROMs. This specific i2c-nforce2-s4985
driver adds support for this. It is heavily based on the older
i2c-amd756-s4882 driver.

As more mainboards will use multiplexer chips, we will have to find a
way to support them without having to write a new specfic driver for
each. The recent changes to the i2c subsystem should help us, and the
new gpio subsystem might help, too.

-Description 
------------ 
-
-WARNING: If you have an '810' or '815' motherboard, your standard I2C
-temperature sensors are most likely on the 801's I2C bus. You want the
-i2c-i801 driver for those, not this driver.
-
-Now for the i2c-i810...
-
-The GMCH chip contains two I2C interfaces.
-
-The first interface is used for DDC (Data Display Channel) which is a
-serial channel through the VGA monitor connector to a DDC-compliant
-monitor. This interface is defined by the Video Electronics Standards
-Association (VESA). The standards are available for purchase at
-http://www.vesa.org .
-
-The second interface is a general-purpose I2C bus. It may be connected to a
-TV-out chip such as the BT869 or possibly to a digital flat-panel display.
-
-Features
--------- 
-
-Both busses use the i2c-algo-bit driver for 'bit banging'
-and support for specific transactions is provided by i2c-algo-bit.
-
-Issues
-------
-
-If you enable bus testing in i2c-algo-bit (insmod i2c-algo-bit bit_test=1),
-the test may fail; if so, the i2c-i810 driver won't be inserted. However,
-we think this has been fixed.

Create Documentation/i2c/fault-codes to help standardize
fault/error code usage in the I2C stack.  It turns out that
returning -1 (-EPERM) for everything was not at all helpful.

+This is a summary of the most important conventions for use of fault
+codes in the I2C/SMBus stack.
+
+
+A "Fault" is not always an "Error"
+----------------------------------
+Not all fault reports imply errors; "page faults" should be a familiar
+example.  Software often retries idempotent operations after transient
+faults.  There may be fancier recovery schemes that are appropriate in
+some cases, such as re-initializing (and maybe resetting).  After such
+recovery, triggered by a fault report, there is no error.
+
+In a similar way, sometimes a "fault" code just reports one defined
+result for an operation ... it doesn't indicate that anything is wrong
+at all, just that the outcome wasn't on the "golden path".
+
+In short, your I2C driver code may need to know these codes in order
+to respond correctly.  Other code may need to rely on YOUR code reporting
+the right fault code, so that it can (in turn) behave correctly.
+
+
+I2C and SMBus fault codes
+-------------------------
+These are returned as negative numbers from most calls, with zero or
+some positive number indicating a non-fault return.  The specific
+numbers associated with these symbols differ between architectures,
+though most Linux systems use <asm-generic/errno*.h> numbering.
+
+Note that the descriptions here are not exhaustive.  There are other
+codes that may be returned, and other cases where these codes should
+be returned.  However, drivers should not return other codes for these
+cases (unless the hardware doesn't provide unique fault reports).
+
+Also, codes returned by adapter probe methods follow rules which are
+specific to their host bus (such as PCI, or the platform bus).
+
+
+EAGAIN
+	Returned by I2C adapters when they lose arbitration in master
+	transmit mode:  some other master was transmitting different
+	data at the same time.
+
+	Also returned when trying to invoke an I2C operation in an
+	atomic context, when some task is already using that I2C bus
+	to execute some other operation.
+
+EBADMSG
+	Returned by SMBus logic when an invalid Packet Error Code byte
+	is received.  This code is a CRC covering all bytes in the
+	transaction, and is sent before the terminating STOP.  This
+	fault is only reported on read transactions; the SMBus slave
+	may have a way to report PEC mismatches on writes from the
+	host.  Note that even if PECs are in use, you should not rely
+	on these as the only way to detect incorrect data transfers.
+
+EBUSY
+	Returned by SMBus adapters when the bus was busy for longer
+	than allowed.  This usually indicates some device (maybe the
+	SMBus adapter) needs some fault recovery (such as resetting),
+	or that the reset was attempted but failed.
+
+EINVAL
+	This rather vague error means an invalid parameter has been
+	detected before any I/O operation was started.  Use a more
+	specific fault code when you can.
+
+	One example would be a driver trying an SMBus Block Write
+	with block size outside the range of 1-32 bytes.
+
+EIO
+	This rather vague error means something went wrong when
+	performing an I/O operation.  Use a more specific fault
+	code when you can.
+
+ENODEV
+	Returned by driver probe() methods.  This is a bit more
+	specific than ENXIO, implying the problem isn't with the
+	address, but with the device found there.  Driver probes
+	may verify the device returns *correct* responses, and
+	return this as appropriate.  (The driver core will warn
+	about probe faults other than ENXIO and ENODEV.)
+
+ENOMEM
+	Returned by any component that can't allocate memory when
+	it needs to do so.
+
+ENXIO
+	Returned by I2C adapters to indicate that the address phase
+	of a transfer didn't get an ACK.  While it might just mean
+	an I2C device was temporarily not responding, usually it
+	means there's nothing listening at that address.
+
+	Returned by driver probe() methods to indicate that they
+	found no device to bind to.  (ENODEV may also be used.)
+
+EOPNOTSUPP
+	Returned by an adapter when asked to perform an operation
+	that it doesn't, or can't, support.
+
+	For example, this would be returned when an adapter that
+	doesn't support SMBus block transfers is asked to execute
+	one.  In that case, the driver making that request should
+	have verified that functionality was supported before it
+	made that block transfer request.
+
+	Similarly, if an I2C adapter can't execute all legal I2C
+	messages, it should return this when asked to perform a
+	transaction it can't.  (These limitations can't be seen in
+	the adapter's functionality mask, since the assumption is
+	that if an adapter supports I2C it supports all of I2C.)
+
+EPROTO
+	Returned when slave does not conform to the relevant I2C
+	or SMBus (or chip-specific) protocol specifications.  One
+	case is when the length of an SMBus block data response
+	(from the SMBus slave) is outside the range 1-32 bytes.
+
+ETIMEDOUT
+	This is returned by drivers when an operation took too much
+	time, and was aborted before it completed.
+
+	SMBus adapters may return it when an operation took more
+	time than allowed by the SMBus specification; for example,
+	when a slave stretches clocks too far.  I2C has no such
+	timeouts, but it's normal for I2C adapters to impose some
+	arbitrary limits (much longer than SMBus!) too.

Subject: [PATCH 529/794] i2c-core: Return -Errno, not -1

More updates to the I2C stack's fault reporting:  make the core stop
returning "-1" (usually "-EPERM") for all faults.  Instead, pass lower
level fault code up the stack, or return some appropriate errno.

This patch happens to touch almost exclusively SMBus calls.

The list of I2C/SMBus bus drivers is growing and it is sometimes
difficult for the users to figure out what drivers they should enable.
By grouping the drivers by type, I hope to make the selection easier.

Subject: [PATCH 531/794] i2c: Delete unused function i2c_smbus_write_quick

Function i2c_smbus_write_quick has no users left, so we can delete it.

Also update the list of these helper functions which are gone but
could be added back if needed.

Provide kerneldoc for most of the I2C and SMBus I/O calls.  Add a
comment summarizing some fault reporting issues which affect the
ability to provide clean fault reports through I2C master transfer
calls.  (Making it hard to precisely specify their return values...)

Subject: [PATCH 534/794] i2c: i2c_use_client() defends against NULL

Defend the i2c refcount calls against NULL pointers, as is important
(and conventional) for such calls.  Note that none of the current
callers of i2c_use_client() use its return value.

[JD: I hate this but apparently all the other subsystems do it so...]

Subject: [PATCH 535/794] i2c: Bus drivers return -Errno not -1

Tighten error paths used by various i2c adapters (mostly x86) so
they return real fault/errno codes instead of a "-1" (which is
most often interpreted as "-EPERM").  Build tested, with eyeball
review.

One minor initial goal is to have adapters consistently return
the code "-ENXIO" when addressing a device doesn't get an ACK
response, at least in the probe paths where they are already
good at stifling related logspam.

From fa63cd56d2f09806169307d761e8f430e23bc09b Mon Sep 17 00:00:00 2001
From: Jean Delvare <khali@linux-fr.org>
Date: Mon, 14 Jul 2008 22:38:25 +0200
Subject: [PATCH 536/794] i2c-piix4: Various cleanups and minor fixes

The i2c-piix4 driver was used recently as a model to write a new SMBus
host controller driver and this made me realize that the code of this
old driver wasn't exactly good. So, here are many cleanups and minor
fixes to this driver, so that these minor mistakes aren't duplicated
again:

* Delete unused structure.
* Delete needless forward function declaration.
* Properly announce the SMBus host controller as we find it.
* Spell it SMBus not SMB.
* Return -EBUSY instead of -ENODEV when the I/O region is already in
  use.
* Drop useless masks on the 7-bit address and the R/W bit.
* Reject block transaction requests with an invalid block length.
* Check and report block transaction replies with an invalid block
  length.
* Delete a useless comment.

Subject: [PATCH 537/794] i2c: Consistently reject unsupported transactions

Many PC SMBus host controller drivers don't properly handle the case
where they are requested to achieve a transaction they do not support.
Update them so that the consistently print a warning message and
return a single error value in this case.

Subject: [PATCH 543/794] i2c: Push ioctl BKL down into the i2c code

This is part of the effort to get rid of the BKL.

[JD: In fact i2c-dev doesn't need more locking than is already done
for the other i2c drivers, so we can simply switch to unlocked_ioctl.]

From: Jochen Friedrich <jochen@scram.de>
Date: Mon, 14 Jul 2008 22:38:27 +0200
Subject: [PATCH 544/794] i2c: Add support for I2C bus on Freescale CPM1/CPM2
 controllers

This driver uses the port of 2.4 code from Vitaly Bordug
<vitb@kernel.crashing.org> and the actual algorithm used by the i2c
driver of the DBox code on cvs.tuxboc.org from Felix Domke
(tmbinc@gmx.net) and Gillem (htoa@gmx.net) converted to an
of_platform_driver. Tested on CPM1 (MPC823 on dbox2 hardware) and
CPM2 (MPC8272).

Subject: [PATCH 548/794] i2c: Let bus drivers add SPD to their class

Let general purpose I2C/SMBus bus drivers add SPD to their class. Once
this is done, we will be able to tell the eeprom driver to only probe
for SPD EEPROMs and similar on these buses.

Note that I took a conservative approach here, adding I2C_CLASS_SPD to
many drivers that have no idea whether they can host SPD EEPROMs or not.
This is to make sure that the eeprom driver doesn't stop probing buses
where SPD EEPROMs or equivalent live.

So, bus driver maintainers and users should feel free to remove the SPD
class from drivers those buses never have SPD EEPROMs or they don't
want the eeprom driver to bind to them. Likewise, feel free to add the
SPD class to any bus driver I might have missed.

Subject: [PATCH 550/794] i2c/eeprom: Fall back to SMBus read word transactions

When I2C block reads are not supported by the underlying adapter, use
SMBus read word transactions instead of consecutive byte reads.
Reasons for this change are:

* The consecutive byte read approach is not safe on multi-master buses.

* While consecutive byte reads have less overhead if you only count the
  bytes on the bus, it takes more than twice as many transactions as
  with SMBus read word transactions, and each transaction has a cost:
  taking and releasing the adapter mutex, and for polling drivers,
  waiting for the transaction to complete.

This change yields a significant performance boost at HZ=250 with
EEPROMs on an Intel 82801 bus (basically twice as fast.)

SMBus read word transactions are widely supported so I don't expect
compatibility issues.

Subject: [PATCH 553/794] i2c-ibm_iic: Enable driver for all PPC4xx variants in
 arch/powerpc

Enable the IBM I2C driver for all PPC4xx variants by adding
"ibm,iic" to the compatible list. This way all currently available
arch/powerpc 4xx ports can make use of this driver without any changes.
Additionally all "other" compatible entries are removed since they are
not needed anymore.

Currently all 4xx PPC's have the same compatible I2C macro. If at some
time an incompatibility is detected we can take care of this with an
additional property.

The legacy pcf8574 and pcf8575 drivers should be avoided

Also, correct the pca9539 deprecation to match the current name

Subject: [PATCH 558/794] i2c-i801: Remove verbose debugging messages

Dumping the register values before and after every transaction was
useful during driver development but now it's only spamming the log.

Subject: [PATCH 561/794] i2c-i801: Fix handling of error conditions

Move the check of pre-transaction and post-transaction conditions to
separate functions, and adjust them a bit. Having dedicated functions
for that ensures that errors are handled in a consistent way.

Bit HOST_BUSY of the status register is read-only, so writing to it is
certainly not going to clear it. If this bit is set then we simply
don't want to start the transaction, as it means that somebody else
(ACPI, SMM?) is already using the controller.

Subject: [PATCH 562/794] i2c-sibyte: SWARM I2C board initialization

 The standard rtc-m41t80.c driver cannot be used with the SWARM as it is,
because the board does not provide setup information for the I2C core.
As a result the bus and the address to probe for the M41T80 chip is not
known.

 Here is a set of changes that fix the problem:

1. swarm-i2c.c -- SWARM I2C board setup, currently for the M41T80 chip on
   the bus #1 only (there is a MAX6654 temperature sensor on the bus #0
   which may be added in the future if we have a driver for that chip).

2. The i2c-sibyte.c BCM1250A SMBus controller driver now registers its
   buses as numbered so that board setup is correctly applied.

Subject: [PATCH 564/794] i2c: Check for ACPI resource conflicts

Check for ACPI resource conflicts in i2c bus drivers. I've included
all recent SMBus master drivers for PC hardware.

I've voluntarily left out:
* Drivers that don't run on PCs: they can't conflict with ACPI.
* Bit-banged bus device drivers: it's very unlikely that ACPI would
  deal with such buses.

Subject: [PATCH 566/794] i2c-dev: Delete empty detach_client callback

Implementing detach_client is optional, so there is no point in
an empty implementation.

Likewise, i2c driver IDs are optional, and we don't need one.

From f09f71b24e77a2f2b4e5c98311c8804fc61ad8bc Mon Sep 17 00:00:00 2001
From: Manuel Lauss <mano@roarinelk.homelinux.net>
Date: Mon, 14 Jul 2008 22:38:34 +0200
Subject: [PATCH 567/794] i2c-au1550: Fix PM support

Fix driver power management:
- suspend the PSC while driver is idle.
- move PSC init/deinit to separate functions, as PSC must be
  initialized/shutdown on resume/suspend.

+ * I2C EEPROMs from most vendors are inexpensive and mostly interchangeable.
+ * Differences between different vendor product lines (like Atmel AT24C or
+ * MicroChip 24LC, etc) won't much matter for typical read/write access.
+ * There are also I2C RAM chips, likewise interchangeable. One example
+ * would be the PCF8570, which acts like a 24c02 EEPROM (256 bytes).
+ *
+ * However, misconfiguration can lose data. "Set 16-bit memory address"
+ * to a part with 8-bit addressing will overwrite data. Writing with too
+ * big a page size also loses data. And it's not safe to assume that the
+ * conventional addresses 0x50..0x57 only hold eeproms; a PCF8563 RTC
+ * uses 0x51, for just one example.
+ *
+ * Accordingly, explicit board-specific configuration data should be used
+ * in almost all cases. (One partial exception is an SMBus used to access
+ * "SPD" data for DRAM sticks. Those only use 24c02 EEPROMs.)
+ *
+ * So this driver uses "new style" I2C driver binding, expecting to be
+ * told what devices exist. That may be in arch/X/mach-Y/board-Z.c or
+ * similar kernel-resident tables; or, configuration data coming from
+ * a bootloader.
+ *
+ * Other than binding model, current differences from "eeprom" driver are
+ * that this one handles write access and isn't restricted to 24c02 devices.
+ * It also handles larger devices (32 kbit and up) with two-byte addresses,
+ * which won't work on pure SMBus systems.

From b1204e6ec16468ebf89d9d818bfe425ca7adcdf3 Mon Sep 17 00:00:00 2001
From: Sean MacLennan <smaclennan@pikatech.com>
Date: Mon, 14 Jul 2008 22:38:36 +0200
Subject: [PATCH 570/794] i2c-ibm_iic: Register child nodes

This patch completes the conversion of the IBM IIC driver to an
of-platform driver.

It removes the index from the IBM IIC driver and makes it an unnumbered
driver. It then calls of_register_i2c_devices to properly register all
the child nodes in the DTS.

Subject: [PATCH 572/794] i2c: Call client_unregister for new-style devices too

We call adapter->client_register for both legacy and new-style i2c
devices, however we only call adapter->client_unregister for legacy
drivers. This doesn't make much sense. Usually, drivers will undo
in client_unregister what they did in client_register, so we should
call neither or both for every given i2c device.

In order to ease the transition from legacy to new-style devices, it
seems preferable to actually call both.

Subject: [PATCH 573/794] i2c: Add detection capability to new-style drivers

Add a mechanism to let new-style i2c drivers optionally autodetect
devices they would support on selected buses and ask i2c-core to
instantiate them. This is a replacement for legacy i2c drivers, much
cleaner.

Where drivers had to implement both a legacy i2c_driver and a
new-style i2c_driver so far, this mechanism makes it possible to get
rid of the legacy i2c_driver and implement both enumerated and
detected device support with just one (new-style) i2c_driver.

Here is a quick conversion guide for these drivers, step by step:

* Delete the legacy driver definition, registration and removal.
  Delete the attach_adapter and detach_client methods of the legacy
  driver.

* Change the prototype of the legacy detect function from
    static int foo_detect(struct i2c_adapter *adapter, int address, int kind);
  to
    static int foo_detect(struct i2c_client *client, int kind,
    			  struct i2c_board_info *info);

* Set the new-style driver detect callback to this new function, and
  set its address_data to &addr_data (addr_data is generally provided
  by I2C_CLIENT_INSMOD.)

* Add the appropriate class to the new-style driver. This is
  typically the class the legacy attach_adapter method was checking
  for. Class checking is now mandatory (done by i2c-core.) See
  <linux/i2c.h> for the list of available classes.

* Remove the i2c_client allocation and freeing from the detect
  function. A pre-allocated client is now handed to you by i2c-core,
  and is freed automatically.

* Make the detect function fill the type field of the i2c_board_info
  structure it was passed as a parameter, and return 0, on success. If
  the detection fails, return -ENODEV.

+Device Detection (Standard driver model)
+----------------------------------------
+
+Sometimes you do not know in advance which I2C devices are connected to
+a given I2C bus.  This is for example the case of hardware monitoring
+devices on a PC's SMBus.  In that case, you may want to let your driver
+detect supported devices automatically.  This is how the legacy model
+was working, and is now available as an extension to the standard
+driver model (so that we can finally get rid of the legacy model.)
+
+You simply have to define a detect callback which will attempt to
+identify supported devices (returning 0 for supported ones and -ENODEV
+for unsupported ones), a list of addresses to probe, and a device type
+(or class) so that only I2C buses which may have that type of device
+connected (and not otherwise enumerated) will be probed.  The i2c
+core will then call you back as needed and will instantiate a device
+for you for every successful detection.
+
+Note that this mechanism is purely optional and not suitable for all
+devices.  You need some reliable way to identify the supported devices
+(typically using device-specific, dedicated identification registers),
+otherwise misdetections are likely to occur and things can get wrong
+quickly.

Subject: [PATCH 574/794] powerpc: mman.h export fixups

Commit ef3d3246a0d06be622867d21af25f997aeeb105f ("powerpc/mm: Add Strong
Access Ordering support") in the powerpc/{next,master} tree caused the
following in a powerpc allmodconfig build:

usr/include/asm/mman.h requires linux/mm.h, which does not exist in exported headers

We should not use CONFIG_PPC64 in an unprotected (by __KERNEL__)
section of an exported include file and linux/mm.h is not exported.  So
protect the whole section that is CONFIG_PPC64 with __KERNEL__ and put
the two introduced includes in there as well.

Subject: [PATCH 575/794] powerpc: Add driver for Barrier Synchronization
 Register

Adds a character driver for BSR support on IBM POWER systems including
Power5 and Power6.  The BSR is an optional processor facility not currently
implemented by any other processors.  It's primary purpose is fast large SMP
synchronization.  More details on the BSR are in comments to the code which
follows.  This patch adds BSR driver to pseries_defconfig.

+ of smaller registers which alias to parts of the single whole register.
+ This can potentially allow multiple groups of processes to each have their
+ own private synchronization device.

+ It may be read using 1, 2, 4, or 8 byte loads which must be aligned since

Subject: [PATCH 576/794] powerpc: Add PPC_FEATURE_PSERIES_PERFMON_COMPAT

Background from Maynard Johnson:
As of POWER6, a set of 32 common events is defined that must be
supported on all future POWER processors.  The main impetus for this
compat set is the need to support partition migration, especially from
processor P(n) to processor P(n+1), where performance software that's
running in the new partition may not be knowledgeable about processor
P(n+1).  If a performance tool determines it does not support the
physical processor, but is told (via the
PPC_FEATURE_PSERIES_PERFMON_COMPAT bit) that the processor supports
the notion of the PMU compat set, then the performance tool can
surface just those events to the user of the tool.

PPC_FEATURE_PSERIES_PERFMON_COMPAT indicates that the PMU supports at
least this basic subset of events which is compatible across POWER
processor lines.

Subject: [PATCH 577/794] powerpc: Remove unnecessary condition when
 sanity-checking WIMG bits

It is okay for both _PAGE_GUARDED and _PAGE_COHERENT (G and M) to be set
in the same pte.  In fact, even if that were not the case, there doesn't
seem to be any place where G is set without also setting I (_PAGE_NO_CACHE),
so the test for I is sufficient as a condition to clear _PAGE_COHERENT
when filling the hash table.

Subject: [PATCH 582/794] ibm_newemac: Add MII mode support to the EMAC RGMII
 bridge.

This patch adds support to the RGMII handler in the EMAC driver for
the MII PHY mode such that device tree entries of the form `phy-mode = "mii";'
are recognized and handled appropriately.

While logically, in software, "gmii" and "mii" modes are the same,
they are wired differently, so it makes sense to allow DTS authors to
specify each explicitly.

Subject: [PATCH 583/794] Fix accidental reference to tg3 firmware

We're not updating the tg3 driver to use request_firmware() yet, but a
reference to its firmware accidentally slipped in as part of commit
c4667746 ("dabusb: use request_firmware()"). Remove it again.

 collision

Commit 70f1bba4 ("x86: use ignore macro instead of hash comment") breaks
the 64-bit x86 build on toolchains that have CONFIG_AS_CFI undefined with:

    arch/x86/lib/csum-copy_64.S:48: Error: Macro `ignore' was already defined

because <asm/dwarf2.h> now uses the ignore macro name itself.  Fix this
by changing to __cfi_ignore in dwarf2.h.

Subject: [PATCH 588/794] IB/srp: Remove use of cached P_Key/GID queries

The SRP initiator is currently using ib_find_cached_pkey() and
ib_get_cached_gid() in situations where the uncached ib_find_pkey()
and ib_query_gid() functions serve just as well: sleeping is allowed
and performance is not an issue.  Since we want to eliminate the
cached operations in the long term, convert SRP to use the uncached
variants.

Date: Mon, 14 Jul 2008 23:48:43 -0700
Subject: [PATCH 591/794] IB/sa: Fail requests made while creating new SM AH

This patch solves a race that occurs after an event occurs that causes
the SA query module to flush its SM address handle (AH).  When SM AH
becomes invalid and needs an update it is handled by the global
workqueue.  On the other hand this event is also handled in the IPoIB
driver by queuing work in the ipoib_workqueue that does multicast
joins.  Although queuing is in the right order, it is done to 2
different workqueues and so there is no guarantee that the first to be
queued is the first to be executed.

This causes a problem because IPoIB may end up sending an request to
the old SM, which will take a long time to time out (since the old SM
is gone); this leads to a much longer than necessary interruption in
multicast traffer.

The patch sets the SA query module's SM AH to NULL when the event
occurs, and until update_sm_ah() is done, any request that needs sm_ah
fails with -EAGAIN return status.

For consumers, the patch doesn't make things worse.  Before the patch,
MADs are sent to the wrong SM so the request gets lost.  Consumers can
be improved if they examine the return code and respond to EAGAIN
properly but even without an improvement the situation is not getting
worse.

Subject: [PATCH 592/794] IB/mlx4: Optimize QP stamping

The idea is that for QPs with fixed size work requests (eg selective
signaling QPs), before stamping the WQE, we read the value of the DS
field, which gives the effective size of the descriptor as used in the
previous post.  Then we stamp only that area, since the rest of the
descriptor is already stamped.

When initializing the send queue buffer, make sure the DS field is
initialized to the max descriptor size so that the subsequent stamping
will be done on the entire descriptor area.

From: Roland Dreier <rolandd@cisco.com>
Date: Mon, 14 Jul 2008 23:48:44 -0700

Subject: [PATCH 596/794] IPoIB: Copy small received SKBs in connected mode

The connected mode implementation in the IPoIB driver has a large
overhead in the way SKBs are handled in the receive flow.  It usually
allocates an SKB with as big as was used in the currently received SKB
and moves unused fragments from the old SKB to the new one. This
involves a loop on all the remaining fragments and incurs overhead on
the CPU.  This patch, for small SKBs, allocates an SKB just large
enough to contain the received data and copies to it the data from the
received SKB.  The newly allocated SKB is passed to the stack and the
old SKB is reposted.

When running netperf, UDP small messages, without this pach I get:

    UDP UNIDIRECTIONAL SEND TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to
    14.4.3.178 (14.4.3.178) port 0 AF_INET
    Socket  Message  Elapsed      Messages
    Size    Size     Time         Okay Errors   Throughput
    bytes   bytes    secs            #      #   10^6bits/sec

    114688     128   10.00     5142034      0     526.31
    114688           10.00     1130489            115.71

With this patch I get both send and receive at ~315 mbps.

The reason that send performance actually slows down is as follows:
When using this patch, the overhead of the CPU for handling RX packets
is dramatically reduced.  As a result, we do not experience RNR NAK
messages from the receiver which cause the connection to be closed and
reopened again; when the patch is not used, the receiver cannot handle
the packets fast enough so there is less time to post new buffers and
hence the mentioned RNR NACKs.  So what happens is that the
application *thinks* it posted a certain number of packets for
transmission but these packets are flushed and do not really get
transmitted.  Since the connection gets opened and closed many times,
each time netperf gets the CPU time that otherwise would have been
given to IPoIB to actually transmit the packets.  This can be verified
when looking at the port counters -- the output of ifconfig and the
oputput of netperf (this is for the case without the patch):

    tx packets
    ==========
    port counter:   1,543,996
    ifconfig:       1,581,426
    netperf:        5,142,034

    rx packets
    ==========
    netperf         1,1304,089

Subject: [PATCH 597/794] RDMA/core: Add memory management extensions support

This patch adds support for the IB "base memory management extension"
(BMME) and the equivalent iWARP operations (which the iWARP verbs
mandates all devices must implement).  The new operations are:

 - Allocate an ib_mr for use in fast register work requests.

 - Allocate/free a physical buffer lists for use in fast register work
   requests.  This allows device drivers to allocate this memory as
   needed for use in posting send requests (eg via dma_alloc_coherent).

 - New send queue work requests:
   * send with remote invalidate
   * fast register memory region
   * local invalidate memory region
   * RDMA read with invalidate local memory region (iWARP only)

Consumer interface details:

 - A new device capability flag IB_DEVICE_MEM_MGT_EXTENSIONS is added
   to indicate device support for these features.

 - New send work request opcodes IB_WR_FAST_REG_MR, IB_WR_LOCAL_INV,
   IB_WR_RDMA_READ_WITH_INV are added.

 - A new consumer API function, ib_alloc_mr() is added to allocate
   fast register memory regions.

 - New consumer API functions, ib_alloc_fast_reg_page_list() and
   ib_free_fast_reg_page_list() are added to allocate and free
   device-specific memory for fast registration page lists.

 - A new consumer API function, ib_update_fast_reg_key(), is added to
   allow the key portion of the R_Key and L_Key of a fast registration
   MR to be updated.  Consumers call this if desired before posting
   a IB_WR_FAST_REG_MR work request.

Consumers can use this as follows:

 - MR is allocated with ib_alloc_mr().

 - Page list memory is allocated with ib_alloc_fast_reg_page_list().

 - MR R_Key/L_Key "key" field is updated with ib_update_fast_reg_key().

 - MR made VALID and bound to a specific page list via
   ib_post_send(IB_WR_FAST_REG_MR)

 - MR made INVALID via ib_post_send(IB_WR_LOCAL_INV),
   ib_post_send(IB_WR_RDMA_READ_WITH_INV) or an incoming send with
   invalidate operation.

 - MR is deallocated with ib_dereg_mr()

 - page lists dealloced via ib_free_fast_reg_page_list().

Applications can allocate a fast register MR once, and then can
repeatedly bind the MR to different physical block lists (PBLs) via
posting work requests to a send queue (SQ).  For each outstanding
MR-to-PBL binding in the SQ pipe, a fast_reg_page_list needs to be
allocated (the fast_reg_page_list is owned by the low-level driver
from the consumer posting a work request until the request completes).
Thus pipelining can be achieved while still allowing device-specific
page_list processing.

The 32-bit fast register memory key/STag is composed of a 24-bit index
and an 8-bit key.  The application can change the key each time it
fast registers thus allowing more control over the peer's use of the
key/STag (ie it can effectively be changed each time the rkey is
rebound to a page list).

From e7e55829999deaab3f43e201a087731c02c54cf9 Mon Sep 17 00:00:00 2001
From: Steve Wise <swise@opengridcomputing.com>
Date: Mon, 14 Jul 2008 23:48:45 -0700
Subject: [PATCH 598/794] RDMA/cxgb3: MEM_MGT_EXTENSIONS support

- set IB_DEVICE_MEM_MGT_EXTENSIONS capability bit if fw supports it.
- set max_fast_reg_page_list_len device attribute.
- add iwch_alloc_fast_reg_mr function.
- add iwch_alloc_fastreg_pbl
- add iwch_free_fastreg_pbl
- adjust the WQ depth for kernel mode work queues to account for
  fastreg possibly taking 2 WR slots.
- add fastreg_mr work request support.
- add local_inv work request support.
- add send_with_inv and send_with_se_inv work request support.
- removed useless duplicate enums/defines for TPT/MW/MR stuff.

Subject: [PATCH 599/794] IB/mlx4: Configure QPs' max message size based on
 real device capability

ConnectX returns the max message size it supports through the
QUERY_DEV_CAP firmware command.  When modifying a QP to RTR, the max
message size for the QP must be specified.  This value must not exceed
the value declared through QUERY_DEV_CAP.  The current code ignores
the max allowed size and unconditionally sets the value to 2^31.  This
patch sets all QPs to the max value allowed as returned from firmware.

Subject: [PATCH 601/794] IB/core: Reset to error QP state transition is not
 allowed

I was reviewing the QP state transition diagram in the IB 1.2.1 spec
and the code for qp_state_table[], and noticed that the code allows a
QP to be modified from IB_QPS_RESET to IB_QPS_ERR whereas the notes
for figure 124 (pg 457) specifically says that this transition isn't
allowed.  This is a clarification from earlier versions of the IB
spec, which were ambiguous in this area and suggested that the RESET
to ERR transition was allowed.

Fix up the qp_state_table[] to make RESET->ERR not allowed.

Subject: [PATCH 609/794] IPoIB/cm: Fix racy use of receive WR/SGL in
 ipoib_cm_post_receive_nonsrq()

For devices that don't support SRQs, ipoib_cm_post_receive_nonsrq() is
called from both ipoib_cm_handle_rx_wc() and ipoib_cm_nonsrq_init_rx(),
and these two callers are not synchronized against each other.
However, ipoib_cm_post_receive_nonsrq() always reuses the same receive
work request and scatter list structures, so multiple callers can end
up stepping on each other, which leads to posting garbled work
requests.

Fix this by having the caller pass in the ib_recv_wr and ib_sge
structures to use, and allocating new local structures in
ipoib_cm_nonsrq_init_rx().

Based on a patch by Pradeep Satyanarayana <pradeep@us.ibm.com> and
David Wilder <dwilder@us.ibm.com>, with debugging help from Hoang-Nam
Nguyen <hnguyen@de.ibm.com>.

Subject: [PATCH 610/794] RDMA/core: Add iWARP protocol statistics attributes
 in sysfs

This patch adds a sysfs attribute group called "proto_stats" under
/sys/class/infiniband/$device/ and populates this group with protocol
statistics if they exist for a given device.  Currently, only iWARP
stats are defined, but the code is designed to allow InfiniBand
protocol stats if they become available.  These stats are per-device
and more importantly -not- per port.

Details:

- Add union rdma_protocol_stats in ib_verbs.h.  This union allows
  defining transport-specific stats.  Currently only iwarp stats are
  defined.

- Add struct iw_protocol_stats to define the current set of iwarp
  protocol stats.

- Add new ib_device method called get_proto_stats() to return protocol
  statistics.

- Add logic in core/sysfs.c to create iwarp protocol stats attributes
  if the device is an RNIC and has a get_proto_stats() method.

Subject: [PATCH 612/794] IB/core: Add support for multicast loopback blocking

This patch also adds a creation flag for QPs,
IB_QP_CREATE_MULTICAST_BLOCK_LOOPBACK, which when set means that
multicast sends from the QP to a group that the QP is attached to will
not be looped back to the QP's receive queue.  This can be used to
save receive resources when a consumer does not want a local copy of
multicast traffic; for example IPoIB must waste CPU time throwing away
such local copies of multicast traffic.

This patch also adds a device capability flag that shows whether a
device supports this feature or not.

Subject: [PATCH 614/794] IPoIB: Use multicast loopback blocking if available

Set IB_QP_CREATE_BLOCK_MULTICAST_LOOPBACK for IPoIB's UD QPs if
supported by the underlying device.  This creates an improvement of up
to 39% in bandwidth when sending multicast packets with IPoIB, and an
improvment of 12% in cpu usage.

Subject: [PATCH 615/794] IPoIB: add LRO support

Add "ipoib_use_lro" module parameter to enable LRO and an
"ipoib_lro_max_aggr" module parameter to set the max number of packets
to be aggregated.  Make LRO controllable and LRO statistics accessible
through ethtool.

Subject: [PATCH 617/794] IPoIB: Refresh paths instead of flushing them on SM
 change events

The patch tries to solve the problem of device going down and paths being
flushed on an SM change event. The method is to mark the paths as candidates for
refresh (by setting the new valid flag to 0), and wait for an ARP
probe a new path record query.

The solution requires a different and less intrusive handling of SM
change event. For that, the second argument of the flush function
changes its meaning from a boolean flag to a level.  In most cases, SM
failover doesn't cause LID change so traffic won't stop.  In the rare
cases of LID change, the remote host (the one that hadn't changed its
LID) will lose connectivity until paths are refreshed. This is no
worse than the current state.  In fact, preventing the device from
going down saves packets that otherwise would be lost.

From 1ff66e8c1faee7c2711b84b9c89e1c5fcd767839 Mon Sep 17 00:00:00 2001
From: Roland Dreier <rolandd@cisco.com>
Date: Mon, 14 Jul 2008 23:48:49 -0700
Subject: [PATCH 618/794] RDMA/nes: Encapsulate logic nes_put_cqp_request()

The iw_nes driver repeats the logic

	if (atomic_dec_and_test(&cqp_request->refcount)) {
		if (cqp_request->dynamic) {
			kfree(cqp_request);
		} else {
			spin_lock_irqsave(&nesdev->cqp.lock, flags);
			list_add_tail(&cqp_request->list, &nesdev->cqp_avail_reqs);
			spin_unlock_irqrestore(&nesdev->cqp.lock, flags);
		}
	}

over and over.  Wrap this up in functions nes_free_cqp_request() and
nes_put_cqp_request() to simplify such code.

In addition to making the source smaller and more readable, this shrinks
the compiled code quite a bit:

Subject: [PATCH 619/794] RDMA/cxgb3: Propagate HW page size capabilities

cxgb3 does not currently report the page size capabilities, and
incorrectly reports them internally.

This version changes the bit-shifting to a static value (per Steve's
request).

Subject: [PATCH 620/794] RDMA/nes: Get rid of ring_doorbell parameter of
 nes_post_cqp_request()

Every caller of nes_post_cqp_request() passed it NES_CQP_REQUEST_RING_DOORBELL,
so just remove that parameter and always ring the doorbell.

Subject: [PATCH 624/794] IPoIB: Only set Q_Key once: after joining broadcast
 group

The current code will set the Q_Key for any join of a non-sendonly
multicast group.  The operation involves a modify QP operation, which
is fairly heavyweight, and is only really required after the join of
the broadcast group.  Fix this by adding a parameter to ipoib_mcast_attach()
to control when the Q_Key is set.

Subject: [PATCH 627/794] IPoIB: Use dev_set_mtu() to change mtu

When the driver sets the MTU of the net device outside of its
change_mtu method, it should make use of dev_set_mtu() instead of
directly setting the mtu field of struct netdevice.  Otherwise
functions registered to be called upon MTU change will not get called
(this is done through call_netdevice_notifiers() in dev_set_mtu()).

Subject: [PATCH 628/794] IB/ipath: Use IEEE OUI for vendor_id reported by
 ibv_query_device()

The IB spe. for SubnGet(NodeInfo) and query HCA says that the vendor
ID field should be the IEEE OUI assigned to the vendor.  The ipath
driver was returning the PCI vendor ID instead.  This will affect
applications which call ibv_query_device().  The old value was
0x001fc1 or 0x001077, the new value is 0x001175.

The vendor ID doesn't appear to be exported via /sys so that should
reduce possible compatibility issues.  I'm only aware of Open MPI as a
major application which depends on this change, and they have made
necessary adjustments.

Subject: [PATCH 629/794] IPoIB/cm: Reduce connected mode TX object size

Since IPoIB connected mode does not NETIF_F_SG, we only have one DMA
mapping per send, so we don't need a mapping[] array.  Define a new
struct with a single u64 mapping member and use it for the CM tx_ring.

Subject: [PATCH 630/794] IPoIB: Double default RX/TX ring sizes

Increase IPoIB ring sizes to twice their original sizes (RX: 128->256,
TX: 64->128) to act as a shock absorber for high traffic peaks.  With
the current settings, we have seen cases that there are many calls to
netif_stop_queue(), which causes degradation in throughput.  Also,
larger receive buffer sizes help IPoIB in CM mode to avoid experiencing
RNR NAK conditions due to insufficient receive buffers at the SRQ.

However the code checked that max_recv_sge was not too big, instead of
checking max_send_sge as it should have.  Fix the code to check the
correct condition.

Handling the zero STag in receive work request requires some extra
logic in the driver:

 - Only set the QP_PRIV bit for kernel mode QPs.

- Add a zero STag build function for recv wrs. The uP needs a PBL
  allocated and passed down in the recv WR so it can construct a HW
  PBL for the zero STag S/G entries.  Note: we need to place a few
  restrictions on zero STag usage because of this:

  1) all SGEs in a recv WR must either be zero STag or not.  No mixing.

  2) an individual SGE length cannot exceed 128MB for a zero-stag SGE.
     This should be OK since it's not really practical to allocate
     such a large chunk of pinned contiguous DMA mapped memory.

- Add an optimized non-zero-STag recv wr format for kernel users.
  This is needed to optimize both zero and non-zero STag cracking in
  the recv path for kernel users.

 - Remove the iwch_ prefix from the static build functions.

 - Bump required FW version.

Subject: [PATCH 636/794] RDMA/addr: Keep pointer to netdevice in struct
 rdma_dev_addr

Keep a pointer to the local (src) netdevice in struct rdma_dev_addr,
and copy it in as part of rdma_copy_addr().  Use rdma_translate_ip()
in cma_new_conn_id() to reduce some code duplication and also make
sure the src_dev member gets set.

In a high-availability configuration the netdevice pointer can be used
by the RDMA CM to align RDMA sessions to use the same links as the IP
stack does under fail-over and route change cases.

Subject: [PATCH 637/794] RDMA/cma: Simplify locking needed for serialization
 of callbacks

The RDMA CM has some logic in place to make sure that callbacks on a
given CM ID are delivered to the consumer in a serialized manner.
Specifically it has code to protect against a device removal racing
with a running callback function.

This patch simplifies this logic by using a mutex per ID instead of a
wait queue and atomic variable.  This means that cma_disable_remove()
now is more properly named to cma_disable_callback(), and
cma_enable_remove() can now be removed because it just would become a
trivial wrapper around mutex_unlock().

Subject: [PATCH 638/794] mlx4_core: Use MOD_STAT_CFG command to get minimal
 page size

There was a bug in some versions of the mlx4 driver in
mlx4_alloc_fmr(), which hardcoded the minimum acceptable page_shift to
be 12.  However, new ConnectX firmware can support a minimum
page_shift of 9 (log_pg_sz of 9 returned by QUERY_DEV_LIM) -- so with
old drivers, ib_fmr_alloc() would fail for ULPs using the device
minimum when creating FMRs.

To preserve firmware compatibility with released mlx4 drivers, the
firmware will continue to return 12 as before for log_page_sz in
QUERY_DEV_CAP for these drivers.  However, to enable new drivers to
take advantage of the available smaller page size, the mlx4 driver now
first sets the log_pg_sz to the device minimum by setting a
log_page_sz value to 0 via the MOD_STAT_CFG command and then reading
the real minimum via QUERY_DEV_CAP.

Subject: [PATCH 639/794] IB/mlx4: Use kzalloc() for new QPs so flags are
 initialized to 0

Current code uses kmalloc() and then just does a bitwise OR operation on
qp->flags in create_qp_common(), which means that qp->flags may
potentially have some unintended bits set.  This patch uses kzalloc()
and avoids further explicit clearing of structure members, which also
shrinks the code:

add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-65 (-65)
function                                     old     new   delta

Subject: [PATCH 640/794] Revert "SELinux: allow fstype unknown to policy to
 use xattrs if present"

This reverts commit 811f3799279e567aa354c649ce22688d949ac7a9.

From Eric Paris:

"Please drop this patch for now.  It deadlocks on ntfs-3g.  I need to
rework it to handle fuse filesystems better.  (casey was right)"

make[1]: *** [arch/x86/lib/csum-copy_64.o] Error 1
make: *** [arch/x86/lib] Error 2

It appears that csum-copy_64.S and dwarf2.h both define an ignore macro.
I would expect one of them can be renamed quite easily, unless they
are references elsewhere.

Subject: [PATCH 644/794] [SCSI] scsi_dh: fix kconfig related build errors

Do not automatically "select" SCSI_DH for dm-multipath. If SCSI_DH
doesn't exist,just do not allow  hardware handlers to be used.

Handle SCSI_DH being a module also. Make sure it doesn't allow DM_MULTIPATH
to be compiled in when SCSI_DH is a module.

Subject: [PATCH 646/794] slub: Add check for kfree() of non slab objects.

We can detect kfree()s on non slab objects by checking for PageCompound().
Works in the same way as for ksize. This helped me catch an invalid
kfree().

Subject: [PATCH 648/794] slab: rename slab_destroy_objs

With the removal of destructors, slab_destroy_objs no longer actually
destroys any objects, making the kernel doc incorrect and the function
name misleading.

In keeping with the other debug functions, rename it to
slab_destroy_debugcheck and drop the kernel doc.

Subject: [PATCH 652/794] [MIPS] fix sparse warning about setup_early_printk()

This patch fixes the following sparse warning:

<<<<<<<<

arch/mips/kernel/early_printk.c:35:13: warning: symbol 'setup_early_printk'
was not declared. Should it be static?

<<<<<<<<

The fix is to define a prototype of the setup_early_printk() function and
to include the appropriate header into arch/mips/kernel/early_printk.c.

[Ralf: Sorted includes again]

Subject: [PATCH 653/794] [MIPS] Make two functions static

The following routines

uasm_rel_highest()
uasm_rel_higher()

are needlessly defined global. This patch makes them static.

Compile-tested using a customized config for the Malta board. Booting
the same board up to the shell prompt was also successful with this
patch applied.

Spotted by sparse.

The following routines

allocate_irqno()
free_irqno()

seem not to be used outside of the core kernel code, hence
exporting these functions is pointless. This patch removes
the export.

Subject: [PATCH 659/794] [MIPS] DECstation: Document more MB ASIC register
 bits

 Document a few more register bits provided by the MB ASIC used on R4000SC
(KN04) and R4400SC (KN05) CPU daughtercards with the DECstation.

 Reverse-engineered and not documented anywhere else to the best of my
knowledge.  Bit names appended to the last underscore the same as reported
by the firmware in register dumps.

Subject: [PATCH 660/794] [MIPS] Fix asm constraints for 'ins' instructions.

The third operand to 'ins' must be a constant int, not a register.

[Ralf: The bug was actually intensional.  Some versions used to throw an
error under certain circumstances for code like:

static inline void f(unsigned nr, unsigned *p)
{
	unsigned short bit = nr & 5;

	if (__builtin_constant_p(bit)) {
		__asm__ __volatile__ ("  foo %0, %1" : "=m" (*p) : "i" (bit));
  	} else {
		/* Do something else. */
	}
}

because gcc was not able to figure out that the "i" constraint was possibly
at the early stage when the constraint are getting verified.  The solution
was using "ri" instead of "i".  The "ri" would keep gcc happy but in the
end for code generation always the "i" constraint would be satisfied.  The
problem afair originally appeared in the i386 io.h and also hit it's mips
equivalent.  From there the workaround spread to many of the inline
assembler functions.]

Subject: [PATCH 665/794] [MIPS] A few cleanups in malta_int.c

Both the fill_ipi_map() routine and the gic_intr_map array defined
in arch/mips/mips-boards/malta/malta_int.c are not used outside of
the latter file. Thus, these objects can become static. Moreover,
these two objects are used by the MT code only, which is why this
patch adds the appropriate ifdef.

While at it, this patch removes an unnecessary preprocessing macro
in favor of the commonly used ARRAY_SIZE.

Successfully tested using a Qemu-emulated Malta board for both SMP
and UP kernels.

Subject: [PATCH 681/794] [MIPS] txx9: Make gpio_txx9 entirely spinlock-safe

TXx9 GPIO set/get routines are spinlock-safe.  This patch make
gpio_direction_{input,output} routines also spinlock-safe so that they
can be used during early board setup.

Subject: [PATCH 682/794] [MIPS] TXx9: Reorganize code

Move arch/mips/{jmr3927,tx4927,tx4938} into arch/mips/txx9/ tree.
This will help more code sharing and maintainance.

From 89d63fe179520b11f54de1f26755b7444c79e73a Mon Sep 17 00:00:00 2001
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
Date: Fri, 11 Jul 2008 00:33:08 +0900
Subject: [PATCH 683/794] [MIPS] TXx9: Reorganize PCI code

Split out PCIC dependent code and SoC dependent code from board dependent
code.  Now TX4927 PCIC code is independent from TX4927/TX4938 SoC code.
Also fix some build problems on CONFIG_PCI=n.

As a bonus, "FPCIB0 Backplane Support" is available for all TX39/TX49 boards
and PCI66 support is available for all TX49 boards.

From edcaf1a6a77315562e9781245cc8e028c9a921dc Mon Sep 17 00:00:00 2001
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
Date: Fri, 11 Jul 2008 23:27:54 +0900
Subject: [PATCH 685/794] [MIPS] TXx9: Make single kernel can support multiple
 boards

Make single kernel can be used on RBTX4927/37/38.  Also make
some SoC-specific code independent from board-specific code.

Subject: [PATCH 686/794] [MIPS] TXx9: Update and merge defconfigs

Merge rbhma4200(RBTX4927/37) and rbhma4500(RBTX4938) defconfig into
single rbtx49xx defconfig.  And jmr3927 defconfig is also updated.

Subject: [PATCH 705/794] ide: disable drive interrupts in ide_driveid_update()

Since ide_driveid_update() uses polling to execute the IDENTIFY DEVICE command
but clears nIEN bit in the control register and doesn't mask the IDE interrupt,
the latter does happen and lead to the corresponding message to appear:

ide0: unexpected interrupt, status=0x58, count=1

when e.g. running hdparm with option -X with a non-PCI IDE driver...

Subject: [PATCH 706/794] ide: eliminate FIT() macro

Replace the FIT() macro with the kernel-provided clamp_val() macro.

FIT was always being called with a member of a struct ide_timing,
which are shorts, and constant constraints for the min and max.

Thus we can use clamp_val, rather than clamp_t.

Subject: [PATCH 710/794] ide: use __generic_unplug_device() in
 ide_do_drive_cmd() (take 2)

* Call __elv_add_request() with 'plug' == 1 (so the device will be
  plugged) and then use __generic_unplug_device() instead of calling
  ide_do_request() directly.

v2:
* For blk_pm_resume_request() requests the queue is stopped so we
  need to call ->request_fn explicitly.

  Thanks to:
  - Rafael for reporting/bisecting the bug
  - Borislav/Rafael for testing the fix

This is a preparation for converting IDE to use blk_execute_rq().

Subject: [PATCH 711/794] ide-cd: convert ide_cd_queue_pc to use blk_execute_rq

This converts ide_cd_queue_pc to use blk_execute_rq, necessitating
changing the ide_cd_queue_pc prototype into a form that doesn't takes
a pointer to request struct. ide_cd_queue_pc works like scsi_execute.

Subject: [PATCH 717/794] block: handle blk_pm_resume_request() requests in
 blk_execute_rq_nowait()

For blk_pm_resume_request() requests (which are used only by IDE subsystem
currently) the queue is stopped so we need to call ->request_fn explicitly.

Thanks to:
- Rafael for reporting/bisecting the bug
- Borislav/Rafael for testing the fix

This is a preparation for converting IDE to use blk_execute_rq().

Subject: [PATCH 722/794] block: convert pd_special_command to use
 blk_execute_rq

pd_special_command uses blk_put_request with struct request on the
stack. As a result, blk_put_request needs a hack to catch a NULL
request_queue.  This converts pd_special_command to use
blk_execute_rq.

Subject: [PATCH 723/794] block: remove the checking for NULL queue in
 blk_put_request

Some uses blk_put_request asymmetrically, that is, they uses it with
requests that not allocated by blk_get_request. As a result,
blk_put_request has a hack to catch a NULL request_queue. Now such
callers are fixed (they use blk_get_request properly). So we can
safely remove the hack in blk_put_request.

Just use the new & shiny ide_pad_transfer() helper instead.

Also remove the superfluous check for 'drive->media == ide_disk'
while at it (ide_ata_error() is used only for ide_disk devices).

Subject: [PATCH 730/794] sgiioc4: use ->extra_base instead of ->dma_status for
 dma_handle

This is a preparation for removal of ->dma_status field from ide_hwif_t.

There should be no functional changes caused by this patch.

Subject: [PATCH 732/794] ide: fix do_probe() to use SELECT_DRIVE()

Fix one place in do_probe() which used ->OUTB directly instead
of calling SELECT_DRIVE() (so ->selectproc method is also used).

Subject: [PATCH 733/794] ide: remove IDE_TFLAG_NO_SELECT_MASK taskfile flag

Always call SELECT_MASK(..., 0) in ide_tf_load() (needs to be done
to match ide_set_irq(..., 1)) and then remove IDE_TFLAG_NO_SELECT_MASK
taskfile flag.

This change should only affect hpt366 and icside host drivers since
->maskproc(..., 0) for sgiioc4 is equivalent to ide_set_irq(..., 1).

Subject: [PATCH 735/794] ide: remove ->mmio flag from ide_hwif_t

Since scc_pata host driver no longer uses IDE PCI layer / ide_dma_setup()
and all other ->mmio users set also IDE_HFLAG_MMIO host flag we can safely
remove ->mmio flag.

There should be no functional changes caused by this patch.

Subject: [PATCH 739/794] ide: remove drive->ctl

Remove drive->ctl (it is always equal to 0x08 after init time).

While at it:

* Use ATA_DEVCTL_OBS define.

There should be no functional changes caused by this patch.

Subject: [PATCH 740/794] ide-scsi: replace ide_do_drive_cmd with
 blk_execute_rq_nowait

All the callers of ide_do_drive_cmd() except for ide-scsi use
ide_preempt action argument. This converts ide-scsi to use
blk_execute_rq_nowait instead of ide_do_drive_cmd so that we can
remove the action argument in ide_do_drive_cmd and ide_action_t
typedef.

Subject: [PATCH 741/794] ide: remove action argument in ide_do_drive_cmd

ide_do_drive_cmd is called only with ide_preempt action argument. So
we can remove the action argument in ide_do_drive_cmd and ide_action_t
typedef.

This patch also includes two minor cleanups: 1) ide_do_drive_cmd
always succeeds so we don't need the return value; 2) the callers use
blk_rq_init before ide_do_drive_cmd so there is no need to initialize
rq->errors.

Subject: [PATCH 747/794] ide-scsi: remove superfluous BUG_ON() from

ide_set_handler() bugs on ->handler == NULL so no need to do it
in idescsi_transfer_pc().

There should be no functional changes caused by this patch.

Subject: [PATCH 748/794] ide-scsi: add debug_log() macro

Add debug_log() macro and convert the driver to use it.

[ This makes debug messages to be always prefixed with "ide-scsi: "
  and use KERN_INFO level. ]

While at it:

* Change "DMA complete" debug message to "DMA finished" to match
  other ATAPI device drivers.

* Use __func__.

Subject: [PATCH 756/794] ide-{floppy,tape,scsi}: log device name instead of
 driver name

Log device name instead of driver name in *_pc_intr() and *_transfer_pc*().

While at it:

* Merge two consecutive printk()-s in *_pc_intr() together.

* Replace "floppy"/"tape"/"scsi" references in printk()-s by "device".

Subject: [PATCH 757/794] ide-tape: make idetape_retry_pc() void

idetape_retry_pc() always returns ide_stopped so make it void.

There should be no functional changes caused by this patch.

Subject: [PATCH 758/794] ide-tape: merge callbacks

The appropriate functionality of the callback is established through querying
the ATAPI packet command in pc->c[0].

While at it:
- add uptodate variable + leave just one idetape_end_request() call
- don't use HWGROUP() macro

Subject: [PATCH 760/794] ide-floppy: merge callbacks

The appropriate functionality of the callback is established through querying
the ATAPI packet command in pc->c[0].

While at it, simplify if (floppy->failed_pc)-branch to be found in the original
idefloppy_request_sense_callback().

Bart:
- keep handling for blk_pc_request() requests unchanged + add FIXME
- add uptodate variable + leave just one idefloppy_end_request() call
- add newline to the debug message

Subject: [PATCH 769/794] ide: add ide_transfer_pc() helper

* Add ide-atapi.c file for generic ATAPI support together with
  CONFIG_IDE_ATAPI config option.

* Add generic ide_transfer_pc() helper to ide-atapi.c and then
  convert ide-{floppy,tape,scsi} device drivers to use it.

There should be no functional changes caused by this patch.

Move idescsi_map_sg() call out from idescsi_issue_pc()
to idescsi_do_request() as a preparation to adding generic
ide_issue_pc() helper.

in ide*_issue_pc().  This is a preparation for adding generic
ide_issue_pc() helper.

Add DBG_PC_INTR debug level and use it to always log debug info
in idetape_pc_intr() if debugging is enabled.

While at it:

* Use drive->name instead of tape->name.

* Log device name with "DMA finished" message.

This is a preparation for adding generic ide_pc_intr() helper.

Subject: [PATCH 778/794] ide-scsi: use pc->callback

* Add ide_scsi_callback() pc->callback implementation, then update
  idescsi_check_condition() and idescsi_queue() to setup ->callback.

* Convert idescsi_pc_intr() to use pc->callback.

This is a preparation for adding generic ide_pc_intr() helper.

Subject: [PATCH 781/794] ide: add ide_pc_intr() helper

* ide-tape.c: add 'drive' argument to idetape_update_buffers().

* Add generic ide_pc_intr() helper to ide-atapi.c and then
  convert ide-{floppy,tape,scsi} device drivers to use it.

* ide-tape.c: remove no longer needed DBG_PC_INTR.

There should be no functional changes caused by this patch
(unless the debugging is explicitely compiled in).

Dave Hansen reported a build error on 32bit which went unnoticed
as newer gcc versions seem to optimize unused static functions
away before compiling them.

Make vread_tsc() depend on CONFIG_X86_64

When a GFP_ATOMIC allocation fails, it falls back to allocating the
data on the stack and converting it to a waiting call.

Make sure we actually wait in this case.
