Subject: [PATCH 0001/1079] uwb: safely remove all reservations

When removing all reservations during shutdown, terminate them first and
then wait for any pending timeout work to complete.  This prevents the
timeout work from running after the reservation has been freed.

Subject: [PATCH 0002/1079] wusb: return -ENOTCONN when resetting a port with
 no connected device

If reading the device descriptor fails during hub_port_init() fails,
then the port is disabled, disconnecting the device.  The port is then
reset at the start of the next init attempt but there is no device to
reset.

Subject: [PATCH 0005/1079] itimers: remove the per-cpu-ish-ness

Either we bounce once cacheline per cpu per tick, yielding n^2 bounces
or we just bounce a single..

Also, using per-cpu allocations for the thread-groups complicates the
per-cpu allocator in that its currently aimed to be a fixed sized
allocator and the only possible extention to that would be vmap based,
which is seriously constrained on 32 bit archs.

So making the per-cpu memory requirement depend on the number of
processes is an issue.

Lastly, it didn't deal with cpu-hotplug, although admittedly that might
be fixable.

Subject: [PATCH 0007/1079] ext4: fix wrong use of do_div
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

the following warning:

fs/jbd2/journal.c: In function ‘jbd2_seq_info_show’:
fs/jbd2/journal.c:850: warning: format ‘%lu’ expects type ‘long
unsigned int’, but argument 3 has type ‘uint32_t’

is caused by wrong usage of do_div that modifies the dividend in-place
and returns the quotient. So not only would an incorrect value be
displayed, but s->journal->j_average_commit_time would also be changed
to a wrong value!

Fix it by using div_u64 instead.

Subject: [PATCH 0009/1079] dmaengine: fix dependency chaining

In dmaengine we track the dependencies between the descriptors
using the 'next' pointers of the structure. These pointers are
set to NULL as soon as the corresponding descriptor has been
submitted to the channel (in dma_run_dependencies()).

But, the first 'next' in chain is still remaining set, regardless
the fact, that tx->next has been already submitted. This may lead to
multiple submissions of the same descriptor. This patch fixes this.

Actually, some previous implementation of the xxx_run_dependencies()
function already had this fix in place. The fdb..0eaf3 commit, beside the
correct things, broke this.

The dmaengine sysfs implementation was fixed to support proper
lifetime rules which means that the current:

new_fsl_chan->dev = &new_fsl_chan->common.dev->device;

...retrieves a NULL pointer because new_fsl_chan->common.dev has not
been allocated at this point.  So, set new_fsl_chan->dev to a valid
device.

Subject: [PATCH 0013/1079] x86, generic: mark complex bitops.h inlines as
 __always_inline

Impact: reduce kernel image size

Hugh Dickins noticed that older gcc versions when the kernel
is built for code size didn't inline some of the bitops.

Mark all complex x86 bitops that have more than a single
asm statement or two as always inline to avoid this problem.

Probably should be done for other architectures too.

Ingo then found a better fix that only requires
a single line change, but it unfortunately only
works on gcc 4.3.

On older gccs the original patch still makes a ~0.3% defconfig
difference with CONFIG_OPTIMIZE_INLINING=y.

With gcc 4.1 and a defconfig like build:

    6116998 1138540  883788 8139326  7c323e vmlinux-oi-with-patch
    6137043 1138540  883788 8159371  7c808b vmlinux-optimize-inlining

~20k / 0.3% difference.

Subject: [PATCH 0015/1079] softlock: fix false panic which can occur if
 softlockup_thresh is reduced

At run-time, if softlockup_thresh is changed to a much lower value,
touch_timestamp is likely to be much older than the new softlock_thresh.

This will cause a false softlockup to be detected. If softlockup_panic
is enabled, the system will panic.

The fix is to touch all watchdogs before changing softlockup_thresh.

Subject: [PATCH 0017/1079] x86, pat: fix reserve_memtype() for legacy 1MB
 range

Thierry Vignaud reported:
> http://bugzilla.kernel.org/show_bug.cgi?id=12372
>
> On P4 with an SiS motherboard (video card is a SiS 651)
> X server fails to start with error:
> xf86MapVidMem: Could not mmap framebuffer (0x00000000,0x2000) (Invalid
> argument)

Here X is trying to map first 8KB of memory using /dev/mem. Existing
code treats first 0-4KB of memory as non-RAM and 4KB-8KB as RAM. Recent
code changes don't allow to map memory with different attributes
at the same time.

Fix this by treating the first 1MB legacy region as special and always
track the attribute requests with in this region using linear linked
list (and don't bother if the range is RAM or non-RAM or mixed)

Subject: [PATCH 0018/1079] Revert "kbuild: strip generated symbols from *.ko"

This reverts commit ad7a953c522ceb496611d127e51e278bfe0ff483.

And commit: ("allow stripping of generated symbols under CONFIG_KALLSYMS_ALL")
            9bb482476c6c9d1ae033306440c51ceac93ea80c

These stripping patches has caused a set of issues:

1) People have reported compatibility issues with binutils due to
   lack of support for `--strip-unneeded-symbols' with objcopy 2.15.92.0.2
   Reported by: Wenji
2) ccache and distcc no longer works as expeced
   Reported by: Ted, Roland, + others
3) The installed modules increased a lot in size
   Reported by: Ted, Davej + others

Subject: [PATCH 0021/1079] IPoIB: Fix hang in napi_disable() if P_Key is never
 found

After commit fe25c561 ("IPoIB: Don't enable NAPI when it's already
enabled"), if an interface is brought up but the corresponding P_Key
never appears, then ipoib_stop() will hang in napi_disable(), because
ipoib_open() returns before it does napi_enable().

Fix this by changing ipoib_open() to call napi_enable() even if the
P_Key isn't present.

Subject: [PATCH 0022/1079] crypto: authenc - Fix zero-length IV crash

As it is if an algorithm with a zero-length IV is used (e.g.,
NULL encryption) with authenc, authenc may generate an SG entry
of length zero, which will trigger a BUG check in the hash layer.

This patch fixes it by skipping the IV SG generation if the IV
size is zero.

Subject: [PATCH 0024/1079] IPoIB: Fix deadlock between ipoib_open() and child
 interface create

Fix a deadlock between child interface creation/deletion and ipoib
start/stop.  The former takes vlan_mutex, and then might take RTNL via
register_netdev()/unregister_netdev().  The latter is executed with
RTNL held, and tries to take vlan_mutex, which can lead to an AB-BA
deadlock.

Fix this by having the child interface creation/deletion code take the
RTNL first so vlan_mutex always nests inside RTNL.  We can use
register_netdevice() for child interfaces because we form the
interface name from the parent interface and hence don't need the '%'
expansion of register_netdev().

Subject: [PATCH 0031/1079] ARM: OMAP: Fix gpio.c compile on 15xx with
 CONFIG_DEBUGFS

There are no wakeup registers on 15xx, and suspend_wakeup
does not exist in the struct gpio_bank.

Without this fix we'll get "arch/arm/plat-omap/gpio.c:1792:
error: 'struct gpio_bank' has no member named 'suspend_wakeup'"
as noted by Russell King.

Note that the ifdefs will be cleaned up once the omap gpio
code gets split into omap1 and omap2 specific parts.

Subject: [PATCH 0035/1079] ARM: OMAP: Fix ASoC by enabling writes to XCCR and
 RCCR McBSP registers, v3

This patch enables writing to McBSP Transmit Configuration Control
Register (XCCR) and Receive Configuration Control Register (RCCR)
for 2430/34xx platforms. It also adds XCCR, RCCR entries in McBSP
register configuration structure and bit definitions for both
registers.

If we enable the writing to CCR registers for 2430/34xx and don't
set the default values (setting 0 as a consequence) in ASoC driver,
the Transmit/Receive DMA mode gets disabled and the the
transmission/reception doesn't happen, ending with a
"write error: Input/Output error" when playing with 'aplay'.

Also define dummy CCR registers for omap1.

From e999bbe7f1318390e997d13e508e4f16b1b130af Mon Sep 17 00:00:00 2001
From: Tony Lindgren <tony@atomide.com>
Date: Thu, 15 Jan 2009 13:55:59 +0200
Subject: [PATCH 0036/1079] ARM: OMAP: Remove unused platform devices, v3

This patch removes old platform devices. Alsa should now
be using the ASoC driver. For boards not yet using ASoC,
please see sound/soc/omap/osk5912.c.

Add dummy aic23_power_up and aic23_power_down functions for 770
to keep things compiling.

Remove references to omap_gpio_switch, and unused h2_nand_dev_ready
function.

This patch is based on an earlier patch by Arun KS.

From: Takashi Iwai <tiwai@suse.de>
Date: Thu, 15 Jan 2009 17:31:00 +0100
Subject: [PATCH 0038/1079] ALSA: hda - Fix (yet more) STAC925x issues

The codec-parsing of STAC925x was utterly broken due to its unique
design unlike other STAC codecs.  It has a volume control only in NID
0x0e (similar as STAC9200), but the parser assumes that the amp is
available on each DAC widget.

The patch fixes the whole wrong stories: fix the initial volume,
assign the fixed "Master" volume, and avoid to create wrong volume
controls.

Fix

    drivers/net/mlx4/profile.c: In function `mlx4_make_profile':
    drivers/net/mlx4/profile.c:110: warning: comparison of distinct pointer types lacks a cast

This happened because num_possible_cpus() was secretly changed by
commit ae7a47e7 ("cpumask: make cpumask.h eat its own dogfood.") from
returning "int" to (now) returning "unsigned int".  I think that was a
good change, so we should just swallow the fallout.

Subject: [PATCH 0045/1079] m68k,m68knommu: merge header files

Merge header files for m68k and m68knommu to the single location:

    arch/m68k/include/asm

The majority of this patch was the result of the
script that is included in the changelog below.

The script was originally written by Arnd Bergman and
exten by me to cover a few more files.

When the header files differed the script uses the following:

The original m68k file is named <file>_mm.h  [mm for memory manager]
The m68knommu file is named <file>_no.h [no for no memory manager]

The files uses the following include guard:

This include gaurd works as the m68knommu toolchain set
the __uClinux__ symbol - so this should work in userspace too.

Merging the header files for m68k and m68knommu exposes the
(unexpected?) ABI differences thus it is easier to actually
identify these and thus to fix them.

The commit has been build tested with both a m68k and
a m68knommu toolchain - with success.

The commit has also been tested with "make headers_check"
and this patch fixes make headers_check for m68knommu.

The script used:

Subject: [PATCH 0046/1079] x86: fix assumed to be contiguous leaf page tables
 for kmap_atomic region (take 2)

Debugging and original patch from Nick Piggin <npiggin@suse.de>

The early fixmap pmd entry inserted at the very top of the KVA is causing the
subsequent fixmap mapping code to not provide physically linear pte pages over
the kmap atomic portion of the fixmap (which relies on said property to
calculate pte addresses).

This has caused weird boot failures in kmap_atomic much later in the boot
process (initial userspace faults) on a 32-bit PAE system with a larger number
of CPUs (smaller CPU counts tend not to run over into the next page so don't
show up the problem).

Solve this by attempting to clear out the page table, and copy any of its
entries to the new one. Also, add a bug if a nonlinear condition is encountered
and can't be resolved, which might save some hours of debugging if this fragile
scheme ever breaks again...

Once we have such logic, we can also use it to eliminate the early ioremap
trickery around the page table setup for the fixmap area. This also fixes
potential issues with FIX_* entries sharing the leaf page table with the early
ioremap ones getting discarded by early_ioremap_clear() and not restored by
early_ioremap_reset(). It at once eliminates the temporary (and configuration,
namely NR_CPUS, dependent) unavailability of early fixed mappings during the
time the fixmap area page tables get constructed.

Finally, also replace the hard coded calculation of the initial table space
needed for the fixmap area with a proper one, allowing kernels configured for
large CPU counts to actually boot.

Subject: [PATCH 0047/1079] ext4: only use i_size_high for regular files

Directories are not allowed to be bigger than 2GB, so don't use
i_size_high for anything other than regular files.  E2fsck should
complain about these inodes, but the simplest thing to do for the
kernel is to only use i_size_high for regular files.

This prevents an intentially corrupted filesystem from causing the
kernel to burn a huge amount of CPU and issuing error messages such
as:

EXT4-fs warning (device loop0): ext4_block_to_path: block 135090028 > max

Thanks to David Maciejak from Fortinet's FortiGuard Global Security
Research Team for reporting this issue.

 printk "JBD2", not "EXT3-fs"

Otherwise it can be very confusing to find a "EXT3-fs: " failure in

Subject: [PATCH 0052/1079] quota: Improve locking

We implement dqget() and dqput() that need neither dqonoff_mutex nor dqptr_sem.
Then move dqget() and dqput() calls so that they are not called from under
dqptr_sem. This is important because filesystem callbacks aren't called from
under dqptr_sem which used to cause *lots* of problems with lock ranking
(and with OCFS2 they became close to unsolvable).

The patch also removes two functions which were introduced solely because OCFS2
needed them to cope with the old locking scheme. As time showed, they were not
enough for OCFS2 anyway and it would be unnecessary work to adapt them to the
new locking scheme in which they aren't needed.  As a result OCFS2 needs the
following patch to compile properly with quotas.  Sorry to any bisecters which
hit this in advance.

Subject: [PATCH 0054/1079] IB/mlx4: Fix memory ordering problem when posting
 LSO sends

The current work request posting code writes the LSO segment before
writing any data segments.  This leaves a window where the LSO segment
overwrites the stamping in one cacheline that the HCA prefetches
before the rest of the cacheline is filled with the correct data
segments.  When the HCA processes this work request, a local
protection error may result.

Fix this by saving the LSO header size field off and writing it only
after all data segments are written.  This fix is a cleaned-up version
of a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>.

This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1383>.

Subject: [PATCH 0055/1079] PCI PM: Restore standard config registers of all
 devices early

There is a problem in our handling of suspend-resume of PCI devices that
many of them have their standard config registers restored with
interrupts enabled and they are put into the full power state with
interrupts enabled as well.  This may lead to the following scenario:
  * an interrupt vector is shared between two or more devices
  * one device is resumed earlier and generates an interrupt
  * the interrupt handler of another device tries to handle it and
    attempts to access the device the config space of which hasn't been
    restored yet and/or which still is in a low power state
  * the system crashes as a result

To prevent this from happening we should restore the standard
configuration registers of all devices with interrupts disabled and we
should put them into the D0 power state right after that.
Unfortunately, this cannot be done using the existing
pci_set_power_state(), because it can sleep.  Also, to do it we have to
make sure that the config spaces of all devices were actually saved
during suspend.

Subject: [PATCH 0056/1079] IPoIB: Do not print error messages for multicast
 join retries

When IPoIB tries to join a multicast group, and the SA module's SM
address handle is NULL (because of an SM change, etc), the join
returns with -EAGAIN status.  In that case, don't print an error
message unless multicast debugging is enabled.

Subject: [PATCH 0059/1079] libertas: Fix alignment issues in libertas core

Data structures that come over the wire from the WLAN firmware must be packed.
This fixes alignment problems on the blackfin architecture and, reportedly, on
the AVR32.

This is a replacement for the previous version of this patch which had also
explicitly used get_unaligned_ macros.  As Johannes Berg pointed out, these
macros were unnecessary.

Subject: [PATCH 0060/1079] ath9k: Fix an operator typo in phy rate validation

This was not supposed to be a bitwise AND operation, but a check of
two separate conditions. Anyway, the old code happened to result in
the same behavior, so this is just changing the code to be easier to
understand and also to keep sparse from warning about dubious
operators.

 failure

In function iwl_send_cmd_sync(), if the flag CMD_WANT_SKB is set but
we are not provided with a valid SKB (cmd->meta.u.skb == NULL), we need
to remove the CMD_WANT_SKB flag from the TX cmd queue. Otherwise in case
the cmd comes in later, it will possibly set an invalid address. Thus
it causes an invalid memory access.

This fixed the bug http://bugzilla.kernel.org/show_bug.cgi?id=11326.

Subject: [PATCH 0064/1079] cfg80211: Fix regression with 11d on bands

This fixes a regression on disallowing bands introduced with the new
802.11d support. The issue is that IEEE-802.11 allows APs to send
a subset of what a country regulatory domain defines. This was clarified
in this document:

http://tinyurl.com/11d-clarification

As such it is possible, and this is what is done in practice, that a
single band 2.4 GHz AP will only send 2.4 GHz band regulatory information
through the 802.11 country information element and then the current
intersection with what CRDA provided yields a regulatory domain with
no 5 GHz information -- even though that country may actually allow
5 GHz operation. We correct this by only applying the intersection rules
on a channel if the the intersection yields a regulatory rule on the
same band the channel is on.

Subject: [PATCH 0066/1079] rt2x00: fix a wrong parameter for
 __test_and_clear_bit() in rt2x00rfkill_free().

When running modprobe rt73usb, and then rmmod rt73usb, and then
iwconfig, the wlan0 device does not disappear. When repeating this
process again, we get a kernel Oops errors and "BUG: unable to handle
kernel paging request..." message in the kernel log.

The reason for this is that there is an error in rt2x00rfkill_free(),
which is called in the process of removing the device
(rt2x00lib_remove_dev() in rt2x00dev.c).
rt2x00rfkill_free() clears the RFKILL_STATE_ALLOCATED bit , which is
bit number 1 () in rt2x00dev->flags instead of in
rt2x00dev->rfkill_state. As a result, when checking the
DEVICE_STATE_REGISTERED_HW bit (bit number 1 in rt2x00dev->flags) in
rt2x00lib_remove_hw() it is **unset**, and we wrongly **don't** call
ieee80211_unregister_hw().

This patch corrects this: the parameter for __test_and_clear_bit() in
rt2x00rfkill_free() should be &rt2x00dev->rfkill_state and not
&rt2x00dev->flags.

Subject: [PATCH 0068/1079] p54: fix p54_set_key's return code

p54 doesn't support AES-128-CMAC offload.

This patch will fix the noisy mac80211 warnings, when 802.11w is enabled:
mac80211-phy189: failed to set key (4, ff:ff:ff:ff:ff:ff) to hardware (-22)
mac80211-phy189: failed to set key (5, ff:ff:ff:ff:ff:ff) to hardware (-22)

Subject: [PATCH 0069/1079] IB/ehca: Fix printk format warnings from u64 type
 change

Commit fe333321 ("powerpc: Change u64/s64 to a long long integer
type") changed u64 from unsigned long to unsigned long long, which
means that printk formats for printing u64 values should use "ll"
instead of "l" to avoid warnings.  Fix all the places affected by this
in ehca.

From ee96aae57381e77311538f4a1dd4326f6ae079d1 Mon Sep 17 00:00:00 2001
From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Fri, 16 Jan 2009 14:55:40 -0800
Subject: [PATCH 0070/1079] IB/ehca: Use consistent types for
 ehca_plpar_hcall9()

ehca_plpar_hcall9() takes an unsigned long array, so make all callers
pass that in.  This fixes warnings introduced by commit fe333321
("powerpc: Change u64/s64 to a long long integer type"), which changed
u64 from unsigned long to unsigned long long.

Subject: [PATCH 0073/1079] move wm8400-regulator's probe function to
 .devinit.text
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A pointer to wm8400_regulator_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Meelis reported that on his box /proc/cpuinfo started

It was a stupid bug I introduced when merging
cpu.c for 32 and 64 bit.

The code did an array reference where it had to search
for the right index.

Subject: [PATCH 0080/1079] sparc64: fix modpost failure

Previously PeeCeeI.o was a library but it
was always pulled in due to insw and friends being exported
(at least for a modular kernel).

But this resulted in modpost failures if there where no in-kernel
users because then insw & friends were not linked in.

Fix this by including PeeCeeI.o in the kernel unconditionally.

The only drawback for this solution is that a nonmodular kernel
will always include insw & friends no matter if they are in use or not.

Subject: [PATCH 0088/1079] UBI: allow all ioctls

Some ioctl's in UBI are enabled only when debugging is switched
on. There is not particular reason for this, just noone needed
them. However, some people need the now for their user-space
development. Thus, allow these ioctl's even if UBI debugging
is disabled.

Subject: [PATCH 0090/1079] UBIFS: do not commit twice

VFS calls '->sync_fs()' twice - first time with @wait = 0, second
time with @wait = 1. As a result, we may commit and synchronize
write-buffers twice. Avoid doing this by returning immediatelly if
@wait = 0.

Subject: [PATCH 0092/1079] UBI: add ioctl compatibility

UBI ioctl's do not work when running 64-bit kernel and 32-bit
user-land. Fix this by adding the compat_ioctl method.

Also, UBI serializes all ioctls, so more than one ioctl at a time
is not a problem. Amd UBI does not seem to depend on anything else,
so use unlocked_ioctl instead of ioctl (no BKL needed).

for FRAME_POINTER from X86 to ARCH_WANT_FRAME_POINTERS, but didn't

This patch adds the definition for ARCH_WANT_FRAME_POINTERS. Without it,
FRAME_POINTER can't be enabled on x86.

Subject: [PATCH 0096/1079] x86: put trigger in to detect mismatched apic
 versions

Impact: add debug warning

Fire off one message if two apic's discovered with different
apic versions. (this code is only called during CPU init)

The goal of this is to pave the way of the removal of the apic_version[]
array. We dont expect any apic version incompatibilities in the x86
landscape of systems [if so we dont handle them very well and probably
never will handle deep apic version assymetries well], but it's prudent
to have a debug check for one kernel cycle nevertheless.

Add a debug check to test this theory. If it triggers then it
triggers because the resume code calls it with irqs enabled,
which is a no-no not just for timekeeping_resume(), but also
bad for a number of other resume handlers.

Subject: [PATCH 0098/1079] x86: fix section mismatch warnings in
 kernel/setup_percpu.c

The function setup_cpu_local_masks() has been marked __init, in
order to remove the following section mismatch messages:

WARNING: vmlinux.o(.text+0x3c2c7): Section mismatch in reference from the function setup_cpu_local_masks() to the function .init.text:alloc_bootmem_cpumask_var()
The function setup_cpu_local_masks() references
the function __init alloc_bootmem_cpumask_var().

Subject: [PATCH 0099/1079] cpuset: fix possible deadlock in
 async_rebuild_sched_domains

Lockdep reported some possible circular locking info when we tested cpuset on
NUMA/fake NUMA box.

=======================================================
[ INFO: possible circular locking dependency detected ]
2.6.29-rc1-00224-ga652504 #111
-------------------------------------------------------
bash/2968 is trying to acquire lock:
 (events){--..}, at: [<ffffffff8024c8cd>] flush_work+0x24/0xd8

but task is already holding lock:
 (cgroup_mutex){--..}, at: [<ffffffff8026ad1e>] cgroup_lock_live_group+0x12/0x29

which lock already depends on the new lock.
......
-------------------------------------------------------

Steps to reproduce:
# mkdir /dev/cpuset
# mount -t cpuset xxx /dev/cpuset
# mkdir /dev/cpuset/0
# echo 0 > /dev/cpuset/0/cpus
# echo 0 > /dev/cpuset/0/mems
# echo 1 > /dev/cpuset/0/memory_migrate
# cat /dev/zero > /dev/null &
# echo $! > /dev/cpuset/0/tasks

This is because async_rebuild_sched_domains has the following lock sequence:
run_workqueue(async_rebuild_sched_domains)
	-> do_rebuild_sched_domains -> cgroup_lock

But, attaching tasks when memory_migrate is set has following:
cgroup_lock_live_group(cgroup_tasks_write)
	-> do_migrate_pages -> flush_work

This patch fixes it by using a separate workqueue thread.

Subject: [PATCH 0100/1079] xfs: fix dentry aliasing issues in open_by_handle

Open by handle just grabs an inode by handle and then creates itself
a dentry for it.  While this works for regular files it is horribly
broken for directories, where the VFS locking relies on the fact that
there is only just one single dentry for a given inode, and that
these are always connected to the root of the filesystem so that
it's locking algorithms work (see Documentations/filesystems/Locking)

Remove all the existing open by handle code and replace it with a small
wrapper around the exportfs code which deals with all these issues.
At the same time we also make the checks for a valid handle strict
enough to reject all not perfectly well formed handles - given that
we never hand out others that's okay and simplifies the code.

Subject: [PATCH 0101/1079] xfs: use mnt_want_write in compat_attrmulti ioctl

The compat version of the attrmulti ioctl needs to ask for and then
later release write access to the mount just like the native version,
otherwise we could potentially write to read-only mounts.

We can have both a a quota hash chain and the per-mount list locked at
the same time.  But given that both use the same struct dqhash as list
head we have to tell lockdep that they are different lock classes.

xfs_dqlock2 locks two xfs_dquots, which is fine as it always locks the

Subject: [PATCH 0104/1079] xfs: add a lock class for group/project dquots

We can have both a user and a group/project dquot locked at the same time,
as long as the user dquot is locked first.  Tell lockdep about that fact
by making the group/project dquots a different lock class.

Subject: [PATCH 0105/1079] xfs: fix bad_features2 fixups for the root
 filesystem

Currently the bad_features2 fixup and the alignment updates in the superblock
are skipped if we mount a filesystem read-only.  But for the root filesystem
the typical case is to mount read-only first and only later remount writeable
so we'll never perform this update at all.  It's not a big problem but means
the logs of people needing the fixup get spammed at every boot because they
never happen on disk.

Subject: [PATCH 0106/1079] xfs: sanity check attr fork size

Recently we have quite a few kerneloops reports about dereferencing a NULL
if_data in the attribute fork.  From looking over the code this can only
happen if we pass a 0 size argument to xfs_iformat_local.  This implies some
sort of corruption and in fact the only mailinglist report about this from
earlier this year was after a powerfail presumably on a system with write
cache and without barriers.

Add a quick sanity check for the attr fork size in xfs_iformat to catch
these early and without an oops.

Subject: [PATCH 0108/1079] drm: fix leak of device mappings since multi-master
 changes.

Device maps now contain a link to the master that created them, so
when cleaning up the master, remove any maps that are connected to it.
Also delete any remaining maps at driver unload time.

drivers/ide/palm_bk3710.c: In function 'palm_bk3710_probe':
drivers/ide/palm_bk3710.c:382: warning: assignment makes integer from pointer without a cast

Someone should fix hw_regs_t to neither be a typedef, nor
use "unsigned long" where it should use "void __iomem *".

Impact: remove potential circular lock dependency with cpu hotplug lock

This has caused more problems than it solved, with a pile of cpu
hotplug locking issues.

Followup patches will get_online_cpus() in callers that need it, but
if they don't do it they're no worse than before when they were using
set_cpus_allowed without locking.

Subject: [PATCH 0119/1079] cpufreq: use work_on_cpu in acpi-cpufreq.c for
 drv_read and drv_write

Impact: use new work_on_cpu function to reduce stack usage

Replace the saving of current->cpus_allowed and set_cpus_allowed_ptr() with
a work_on_cpu function for drv_read() and drv_write().

Basically converts do_drv_{read,write} into "work_on_cpu" functions that
are now called by drv_read and drv_write.

Note: This patch basically reverts 50c668d6 which reverted 7503bfba, now
that the work_on_cpu() function is more stable.

Subject: [PATCH 0123/1079] i.MX31: Image Processing Unit DMA and IRQ drivers

i.MX3x SoCs contain an Image Processing Unit, consisting of a Control
Module (CM), Display Interface (DI), Synchronous Display Controller (SDC),
Asynchronous Display Controller (ADC), Image Converter (IC), Post-Filter
(PF), Camera Sensor Interface (CSI), and an Image DMA Controller (IDMAC).
CM contains, among other blocks, an Interrupt Generator (IG) and a Clock
and Reset Control Unit (CRCU). This driver serves IDMAC and IG. They are
supported over dmaengine and irq-chip APIs respectively.

IDMAC is a specialised DMA controller, its DMA channels cannot be used for
general-purpose operations, even though it might be possible to configure
a memory-to-memory channel for memcpy operation. This driver will not work
with generic dmaengine clients, clients, wishing to use it must use
respective wrapper structures, they also must specify which channels they
require, as channels are hard-wired to specific IPU functions.

-tip testing found this crash:

arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.c is still broken: there's no
allocation of the variable mask, so we pass in an uninitialized cmd.mask
field to drv_read(), which then passes it to the scheduler which then
crashes ...

Switch it over to the much simpler constant-cpumask-pointers approach.

Subject: [PATCH 0125/1079] x86: remove kernel_physical_mapping_init() from
 init section

Impact: fix crash with memory hotplug enabled

kernel_physical_mapping_init() is called during memory hotplug
so it does not belong in the init section.

If the kernel is built with CONFIG_DEBUG_SECTION_MISMATCH=y on
the make command line, arch/x86/mm/init_64.c is compiled with
the -fno-inline-functions-called-once gcc option defeating
inlining of kernel_physical_mapping_init() within init_memory_mapping().

When kernel_physical_mapping_init() is not inlined it is placed
in the .init.text section according to the __init in it's current
declaration.  A later call to kernel_physical_mapping_init() during
a memory hotplug operation encounters an int3 trap because the
.init.text section memory has been freed.

This patch eliminates the crash caused by the int3 trap by moving the
non-inlined kernel_physical_mapping_init() from .init.text to .meminit.text.

Subject: [PATCH 0141/1079] macb: avoid lockup when TGO during underrun
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In rare cases when an underrun occur, all macb buffers where consumed
and the netif_queue was stopped infinitely. This happens then the TGO
(transfer ongoing) bit in the TSR is set (and UND). It seems like
clening up after the underrun makes the driver and the macb hardware
end up in an inconsistent state. The result of this is that in the
following calls to macb_tx no TX buffers are released -> the
netif_queue was stopped, and never woken up again.

The solution is to disable the transmitter, if TGO is set, before
clening up after the underrun, and re-enable the transmitter when the
cleaning up is done.

After the last loop iteration, i has the value RC32434_NUM_RDS and
therefore leads to an index overflow when used afterwards to address the
last element. This is yet another another bug introduced when rewriting
parts of the driver for upstream preparation, as the original driver
used 'RC32434_NUM_RDS - 1' instead.

Register VLAN ID 0 so that frames with VLAN ID 0 are received and get
their tag stripped when ixgbe is not in DCB mode.  VLAN ID 0 means
that the frame is 'priority tagged' only - it is not a VLAN, but the
priority value is the tag in valid.  The functions
ixgbe_vlan_rx_register() and ixgbe_vlan_rx_kill_vid() were moved up a
couple functions to correct compiling issues with this change.

Subject: [PATCH 0149/1079] ixgbe: Fix usage of netif_*_all_queues() with
 netif_carrier_{off|on}()

netif_carrier_off() is sufficient to stop Tx into the driver.  Stopping the Tx
queues is redundant and unnecessary.  By the same token, netif_carrier_on()
will be sufficient to re-enable Tx, so waking the queues is unnecessary.

Subject: [PATCH 0150/1079] tg3: Fix firmware loading

This patch modifies how the tg3 driver handles device firmware.

The patch starts by consolidating David Woodhouse's earlier patch under
the same name.  Specifically, the patch moves the request_firmware call
into a separate tg3_request_firmware() function and calls that function
from tg3_open() rather than tg3_init_one().

The patch then goes on to limit the number of devices that will make
request_firmware calls.  The original firmware patch unnecessarily
requested TSO firmware for devices that did not need it.  This patch
reduces the set of devices making TSO firmware patches to approximately
the following device set : 5703, 5704, and 5705.

Finally, the patch reduces the effects of a request_firmware() failure.
For those devices that are requesting TSO firmware, the driver will turn
off the TSO capability.  If TSO firmware becomes available at a later
time, the device can be closed and then opened again to reacquire the
TSO capability.

Subject: [PATCH 0151/1079] net: Fix data corruption when splicing from
 sockets.

The trick in socket splicing where we try to convert the skb->data
into a page based reference using virt_to_page() does not work so
well.

The idea is to pass the virt_to_page() reference via the pipe
buffer, and refcount the buffer using a SKB reference.

But if we are splicing from a socket to a socket (via sendpage)
this doesn't work.

The from side processing will grab the page (and SKB) references.
The sendpage() calls will grab page references only, return, and
then the from side processing completes and drops the SKB ref.

The page based reference to skb->data is not enough to keep the
kmalloc() buffer backing it from being reused.  Yet, that is
all that the socket send side has at this point.

This leads to data corruption if the skb->data buffer is reused
by SLAB before the send side socket actually gets the TX packet
out to the device.

The fix employed here is to simply allocate a page and copy the
skb->data bytes into that page.

This will hurt performance, but there is no clear way to fix this
properly without a copy at the present time, and it is important
to get rid of the data corruption.

With fixes from Herbert Xu.

This reverts commit cd4ccf76bfd2c36d351e68be7e6a597268f98a1a.

On the Pegasos board, we can't do DMA burst that are longer than
one cache line.  For now, go back to using 32 byte DMA bursts for
all mv643xx_eth platforms -- we can switch the ARM-based platforms
back to doing long 128 byte bursts in the next development cycle.

Commit 66e63ffbc04706568d8789cbb00eaa8ddbcae648 ("mv643xx_eth:
implement ->set_rx_mode()") cleaned up mv643xx_eth's multicast filter
programming, but broke it as well.

The non-special multicast filter table (for multicast addresses that
are not of the form 01:00:5e:00:00:xx) consists of 256 hash table
buckets organised as 64 32-bit words, where the 'accept' bits are
in the LSB of each byte, so in bits 24 16 8 0 of each 32-bit word.
The old code got this right, but the referenced commit broke this by
using bits 3 2 1 0 instead.  This commit fixes this up.

Subject: [PATCH 0154/1079] mv643xx_eth: prevent interrupt storm on ifconfig
 down

Contrary to what the docs say, the 'extended interrupt cause' bit in
the interrupt cause register (bit 1) appears to not be maskable on at
least some of the mv643xx_eth platforms, making writing zeroes to the
interrupt mask register but not the extended interrupt mask register
insufficient to stop interrupts from occuring.  Therefore, also write
zeroes to the extended interrupt mask register when shutting down the
port.

This fixes the interrupt storm seen on the Pegasos board when shutting
down the interface.

Subject: [PATCH 0155/1079] wimax/i2400m: error paths that need to free an skb
 should use kfree_skb()

Roel Kluin reported a bug in two error paths where skbs were wrongly
being freed using kfree(). He provided a fix where it was replaced to
kfree_skb(), as it should be.

However, in i2400mu_rx(), the error path was missing returning an
indication of the failure. Changed to reset rx_skb to NULL and return
it to the caller, i2400mu_rxd(). It will be treated as a transient
error and just ignore the packet.

Depending on the buffering conditions inside the device, the data
packet might be dropped or the device will signal the host again for
data-ready-to-read and the host will retry.

Subject: [PATCH 0158/1079] sparc64: Fix DAX handling via userspace access from
 kernel.

If we do a userspace access from kernel mode, and get a
data access exception, we need to check the exception
table just like a normal fault does.

The spitfire DAX handler was doing this, but such logic
was missing from the sun4v DAX code.

Subject: [PATCH 0161/1079] ring-buffer: fix alignment problem

Impact: fix to allow some archs to use the ring buffer

Commits in the ring buffer are checked by pointer arithmetic.
If the calculation is incorrect, then the commits will never take
place and the buffer will simply fill up and report an error.

Each page in the ring buffer has a small header:

struct buffer_data_page {
	u64		time_stamp;
	local_t		commit;
	unsigned char	data[];
};

Unfortuntely, some of the calculations used sizeof(struct buffer_data_page)
to know the size of the header. But this is incorrect on some archs,
where sizeof(struct buffer_data_page) does not equal
offsetof(struct buffer_data_page, data), and on those archs, the commits
are never processed.

This patch replaces the sizeof with offsetof.

Subject: [PATCH 0167/1079] UBI: fix resource de-allocation

GregKH asked to fix UBI which has fake device release method. Indeed,
we have to free UBI device description object from the release method,
because otherwise we'll oops is someone opens a UBI device sysfs file,
then the device is removed, and he reads the file. With this fix, he
will get -ENODEV instead of an oops.

Subject: [PATCH 0168/1079] Revert "xfrm: For 32/64 compatability wrt.
 xfrm_usersa_info"

This reverts commit fc8c7dc1b29560c016a67a34ccff32a712b5aa86.

As indicated by Jiri Klimes, this won't work.  These numbers are
not only used the size validation, they are also used to locate
attributes sitting after the message.

Subject: [PATCH 0170/1079] firewire: insist on successive self ID complete
 events

The whole topology code only works if the old and new topologies which
are compared come from immediately successive self ID complete events.

If there happened bus resets without self ID complete events in the
meantime, or self ID complete events with invalid selfIDs, the topology
comparison could identify nodes wrongly, or more likely just corrupt
kernel memory or panic right away.

We now discard all nodes of the old topology and treat all current nodes
as new ones if the current self ID generation is not the previous one
plus 1.

 rollover

Noticed by Jarod Wilson:  The bus manager work was unnecessarily delayed
each time the bus generation counter rolled over.

Subject: [PATCH 0172/1079] firewire: keep highlevel drivers attached during
 brief connection loss

There are situations when nodes vanish from the bus and come back
quickly thereafter:
  - When certain bus-powered hubs are plugged in,
  - when certain devices are plugged into 6-port hubs,
  - when certain disk enclosures are switched from self-power to bus
    power or vice versa and break the daisy chain during the transition,
  - when the user plugs a cable out and quickly plugs it back in, e.g.
    to reorder a daisy chain (works on Mac OS X if done quickly enough),
  - when certain hubs temporarily malfunction during high bus traffic.

Until now, firewire-core reported affected nodes as lost to the
highlevel drivers (firewire-sbp2 and userspace drivers).  We now delay
the destruction of device representations until after at least two
seconds after the last bus reset.  If a "new" device is detected in this
period whose bus information block and root directory header match that
of a device which is pending for deletion, we resurrect that device and
send update calls to highlevel drivers.

Subject: [PATCH 0173/1079] ASoC: fix registration of the SoC card in the
 Freescale MPC8610 drivers

The Freescale MPC8610 driver was defining two SOC card (snd_soc_card)
structures, partially initializing each one, but registering only one of
them with ASoC.

The previous fix to paged packets broke the merging because it
reset the skb->len before we added it to the merged packet.  This
wasn't detected because it simply resulted in the truncation of
the packet while the missing bit is subsequently retransmitted.

The fix is to store skb->len before we clobber it.

Subject: [PATCH 0181/1079] driver core: Convert '/' to '!' in dev_set_name()

Commit 3ada8b7e ("block: struct device - replace bus_id with dev_name(),
dev_set_name()") deleted the code in register_disk() that changed a '/'
to a '!' in the device name when registering a disk, but dev_set_name()
does not perform this conversion.

This leads to amusing problems with disks that have '/' in their names:
for example a failure to boot with the root partition on a cciss device,
even though the kernel says it knows about the root device:

    VFS: Cannot open root device "cciss/c0d0p6" or unknown-block(0,0)
    Please append a correct "root=" boot option; here are the available partitions:
    6800        71652960 cciss/c0d0 driver: cciss
      6802               1 cciss/c0d0p2
      6805         2931831 cciss/c0d0p5
      6806        34354908 cciss/c0d0p6
    6810        71652960 cciss/c0d1 driver: cciss

Fix this by adding code to change '/' to '!' in dev_set_name() to handle
this until dev_set_name() is converted to use kobject_set_name().

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Toralf Förster <toralf.foerster@gmx.de> reported a build failure in
the WiMAX stack when CONFIG_DEBUG_FS=n

http://linuxwimax.org/pipermail/wimax/2009-January/000449.html

This is due to debugfs_create_size_t() missing an stub that returns
-ENODEV when the DEBUGFS subsystem is not configured in (like the rest
of the debugfs API).

This patch adds said stub.

Subject: [PATCH 0185/1079] klist.c: bit 0 in pointer can't be used as flag

The commit a1ed5b0cffe4b16a93a6a3390e8cee0fbef94f86
(klist: don't iterate over deleted entries) introduces use of the
low bit in a pointer to indicate if the knode is dead or not,
assuming that this bit is always free.

This is not true for all architectures, CRIS for example may align data
on byte borders.

The result is a bunch of warnings on bootup, devices not being
added correctly etc, reported by Hinko Kocevar <hinko.kocevar@cetrtapot.si>:

That works, but we need to do it not for the struct klist_node,
but for the struct we insert into the void * in klist_node,
which is struct klist.

From b9afb0bae5411faadc0afcfbaa8ef0035fc0e8f8 Mon Sep 17 00:00:00 2001
From: Kuninori Morimoto <morimoto.kuninori@renesas.com>
Date: Tue, 2 Dec 2008 16:42:24 +0900
Subject: [PATCH 0189/1079] sh: mach-migor: Delete soc_camera_platform setup.

Migo-R can use ov772x camera driver in Linux 2.6.29.
Therefore, soc_camera_platform setting is no longer needed.
This patch removes it.

("remove linux/hardirq.h from asm-generic/local.h"), the asm/irq.h
definitions that mach-x3proto/setup.c depends on are no longer available,
causing the build to die. So, include linux/irq.h explicitly.

Subject: [PATCH 0197/1079] x86: use early clobbers in usercopy*.c

Impact: fix rare (but currently harmless) miscompile with certain configs and gcc versions

Hugh Dickins noticed that strncpy_from_user() was miscompiled
in some circumstances with gcc 4.3.

Thanks to Hugh's excellent analysis it was easy to track down.

Hugh writes:

> Isn't it returning 0 when it ought to be returning strlen?

The asm constraints for the strncpy_from_user() result were missing an
early clobber, which tells gcc that the last output arguments
are written before all input arguments are read.

Also add more early clobbers in the rest of the file and fix 32-bit
usercopy.c in the same way.

[ since this API is rarely used and no in-kernel user relies on a 'len'
  return value (they only rely on negative return values) this miscompile
  was never noticed in the field. But it's worth fixing it nevertheless. ]

Subject: [PATCH 0198/1079] Revert "x86: signal: change type of paramter for
 sys_rt_sigreturn()"

This reverts commit 4217458dafaa57d8e26a46f5d05ab8c53cf64191.

Justin Madru bisected this commit, it was causing weird Firefox
crashes.

The reason is that GCC mis-optimizes (re-uses) the on-stack parameters of
the calling frame, which corrupts the syscall return pt_regs state and
thus corrupts user-space register state.

So we go back to the slightly less clean but more optimization-safe
method of getting to pt_regs. Also add a comment to explain this.

Resolves: http://bugzilla.kernel.org/show_bug.cgi?id=12505

Subject: [PATCH 0201/1079] sh: Kill off obsolete busses from arch/sh/Kconfig.

ISA can go away now that the hd6446x PCMCIA drivers no longer exist
in-tree. The rationale for enabling CONFIG_ISA in the first place is
likewise no longer valid given that the subsystem has changed since
the time that assertion was valid.

While we are at it, kill off SBUS, MCA, EISA, and so on. These are
not supported and never will be.

Subject: [PATCH 0204/1079] sh: export the sh7343 JPU to user space

This patch exports the sh7343 JPU to user space using uio_pdrv_genirq,
very similar to the sh7722 JPU patch by Hayama-san.

While at it fix up the end of the sh7722 JPU iomem resource.

Subject: [PATCH 0206/1079] nommu: Stub in
 vm_map_ram()/vm_unmap_ram()/vm_unmap_aliases().

Presently we do not support these interfaces, so make them BUG() wrappers
as per the rest of the vmap interface on nommu. Fixes up the modular xfs
build.

Subject: [PATCH 0207/1079] sh: fix unaligned and nonexistent address handling

unaligned and nonexistent address causes wrong exception
handling in traps_32.c(handle_unaligned_access).

'handle_unalinged_ins' should return -EFAULT if address error
is fixed up with kernel exception table, otherwise
'handle_unaligned_access' increases already fixed program counter
and then crash.

for example
   ioctl(fd, TCGETA, (struct termio *)-1)
never return and stay in TASK_UNINTERRUPTIBLE state forever
in my kernel.

Commit 58c6d3dfe436eb8cfb451981d8fdc9044eaf42da ("dma-coherent: catch
oversized requests to dma_alloc_from_coherent()") attempted to add a
sanity check to bail out on allocations larger than the coherent area.

Unfortunately when this was implemented, the fact the coherent area
is tracked in pages rather than bytes was overlooked, which subsequently
broke every single dma_alloc_from_coherent() user, forcing the allocation
silently through generic memory instead.

Subject: [PATCH 0209/1079] dma-coherent: Restore dma_alloc_from_coherent()
 large alloc fall back policy.

When doing large allocations (larger than the per-device coherent area)
the generic memory allocators are silently fallen back on regardless of
consideration for the per-device constraints.

In the DMA_MEMORY_EXCLUSIVE case falling back on generic memory is not
an option, as it tends not to be addressable by the DMA hardware in
question. This issue showed up with the 8139too breakage on the
Dreamcast, where non-addressable buffers were silently allocated due to
the size mismatch calculation -- while it should have simply errored out
upon being unable to satisfy the allocation with the given device
constraints.

This restores fall back behaviour to what it was before the oversized
request change caused multiple regressions.

Subject: [PATCH 0210/1079] x86: fix page attribute corruption with cpa()

Impact: fix sporadic slowdowns and warning messages

This patch fixes a performance issue reported by Linus on his
Nehalem system. While Linus reverted the PAT patch (commit
58dab916dfb57328d50deb0aa9b3fc92efa248ff) which exposed the issue,
existing cpa() code can potentially still cause wrong(page attribute
corruption) behavior.

This patch also fixes the "WARNING: at arch/x86/mm/pageattr.c:560" that
various people reported.

In 64bit kernel, kernel identity mapping might have holes depending
on the available memory and how e820 reports the address range
covering the RAM, ACPI, PCI reserved regions. If there is a 2MB/1GB hole
in the address range that is not listed by e820 entries, kernel identity
mapping will have a corresponding hole in its 1-1 identity mapping.

If cpa() happens on the kernel identity mapping which falls into these holes,
existing code fails like this:

	__change_page_attr_set_clr()
		__change_page_attr()
			returns 0 because of if (!kpte). But doesn't
			set cpa->numpages and cpa->pfn.
		cpa_process_alias()
			uses uninitialized cpa->pfn (random value)
			which can potentially lead to changing the page
			attribute of kernel text/data, kernel identity
			mapping of RAM pages etc. oops!

This bug was easily exposed by another PAT patch which was doing
cpa() more often on kernel identity mapping holes (physical range between
max_low_pfn_mapped and 4GB), where in here it was setting the
cache disable attribute(PCD) for kernel identity mappings aswell.

Fix cpa() to handle the kernel identity mapping holes. Retain
the WARN() for cpa() calls to other not present address ranges
(kernel-text/data, ioremap() addresses)

I realized that the mtrr.show param cannot work, because
the code is processed much too early.

This patch:
 - Declares mtrr.show as early_param
 - Stays consistent with the previous param (which I doubt
   that it ever worked), so mtrr.show=1 would still work
 - Declares mtrr_show as initdata

Subject: [PATCH 0212/1079] tracing/function-graph-tracer: fix a regression
 while suspend to disk

Impact: fix a crash while kernel image restore

When the function graph tracer is running and while suspend to disk, some racy
and dangerous things happen against this tracer.

The current task will save its registers including the stack pointer which
contains the return address hooked by the tracer. But the current task will
continue to enter other functions after that to save the memory, and then
it will store other return addresses, and finally loose the old depth which
matches the return address saved in the old stack (during the registers saving).

So on image restore, the code will return to wrong addresses.
And there are other things: on restore, the task will have it's "current"
pointer overwritten during registers restoring....switching from one task to
another... That would be insane to try to trace function graphs at these
stages.

This patch makes the function graph tracer listening on power events, making
it's tracing disabled for the current task (the one that performs the
hibernation work) while suspend/resume to disk, making the tracing safe
during hibernation.

Subject: [PATCH 0214/1079] trace: print ftrace_dump at KERN_EMERG log level

Impact: fix to print out ftrace_dump when expected

I was debugging a hard race condition to only find out that
after I hit the race, my log level was not at level to show
KERN_INFO. The time it took to trigger the race was wasted because
I did not capture the trace.

Since ftrace_dump is only called from kernel oops (and only when
it is set in the kernel command line to do so), or when a
developer adds it to their own local tree, the log level of
the print should be at KERN_EMERG to make sure the print appears.

ftrace_dump is not called by a normal user setup, and will not
add extra unwanted print out to the console. There is no reason
it should be at KERN_INFO.

Subject: [PATCH 0215/1079] trace: stop all recording to ring buffer on
 ftrace_dump

Impact: limit ftrace dump output

Currently ftrace_dump only calls ftrace_kill that is a fast way
to prevent the function tracer functions from being called (just sets
a flag and clears the function to call, nothing else). It is better
to also turn off any recording to the ring buffers as well.

Subject: [PATCH 0216/1079] trace: set max latency variable to zero on default

Impact: trace max latencies on start of latency tracing

This patch sets the max latency to zero whenever one of the
irq variant tracers or the wakeup tracer is set to current tracer.

Most developers expect to see output when starting up a latency
tracer. But since the max_latency is already set to max, and
it takes a latency greater than max_latency to be recorded, there
is no trace. This is not the expected behavior and has even confused
myself.

so early. So we can just remove all this complicated stuff.

Subject: [PATCH 0222/1079] Btrfs: Remove extra KERN_INFO in the middle of a
 line

The "devid <xxx> transid <xxx>" printk in btrfs_scan_one_device()
actually follows another printk that doesn't end in a newline (since the
intention is for the two printks to make one line of output), so the
KERN_INFO just ends up messing up the output:

    device label exp <6>devid 1 transid 9 /dev/sda5

Fix this by changing the extra KERN_INFO to KERN_CONT.

Subject: [PATCH 0226/1079] Btrfs: Fix infinite loop in btrfs_extent_post_op

btrfs_extent_post_op calls finish_current_insert and del_pending_extents. They
both may enter infinite loops.

finish_current_insert enters infinite loop if it only finds some backrefs to
update.  The fix is to check for pending backref updates before restarting the
loop.

The infinite loop in del_pending_extents is due to a the skipped variable
not being properly reset before looping around.

Subject: [PATCH 0229/1079] Btrfs: fix stop searching test in
 replace_one_extent

replace_one_extent searches tree leaves for references to a given extent. It
stops searching if it goes beyond the last possible position.

The last possible position is computed by adding the starting offset of a found
file extent to the full size of the extent. The code uses physical size of the
extent as the full size. This is incorrect when compression is used.

The fix is get the full size from ram_bytes field of file extent item.

 using /dev/mem

Beschorner Daniel reported:

>	Corrupted page table at address 7fd04de3ec00

Also, PaX Team reported a regression with this commit:

>	    x86: track memtype for RAM in page struct

This commit breaks mapping any RAM page through /dev/mem, as the
reserve_memtype() was not initializing the return attribute type and as such
corrupting the PTE entry that was setup with the return attribute type.

Because of this bug, application mapping this RAM page through /dev/mem
will die with "Corrupted page table at address xxxx" message in the kernel
log and also the kernel identity mapping which maps the underlying RAM
page gets converted to UC.

Fix this by initializing the return attribute type before calling
reserve_ram_pages_type()

Subject: [PATCH 0233/1079] Btrfs: fix tree logs parallel sync

To improve performance, btrfs_sync_log merges tree log sync
requests. But it wrongly merges sync requests for different
tree logs. If multiple tree logs are synced at the same time,
only one of them actually gets synced.

This patch has following changes to fix the bug:

Move most tree log related fields in btrfs_fs_info to
btrfs_root. This allows merging sync requests separately
for each tree log.

Don't insert root item into the log root tree immediately
after log tree is allocated. Root item for log tree is
inserted when log tree get synced for the first time. This
allows syncing the log root tree without first syncing all
log trees.

At tree-log sync, btrfs_sync_log first sync the log tree;
then updates corresponding root item in the log root tree;
sync the log root tree; then update the super block.

From 35054394c4b3cecd52577c2662c84da1f3e73525 Mon Sep 17 00:00:00 2001
From: Chris Mason <chris.mason@oracle.com>
Date: Wed, 21 Jan 2009 13:11:13 -0500
Subject: [PATCH 0234/1079] Btrfs: stop providing a bmap operation to avoid
 swapfile corruptions

Swapfiles use bmap to build a list of extents belonging to the file,
and they assume these extents won't change over the life of the file.
They also use resulting list to do IO directly to the block device.

This causes problems for btrfs in a few ways:

btrfs returns logical block numbers through bmap, and these are not suitable
for IO.  They might translate to different devices, raid etc.

COW means that file block mappings are going to change frequently.

Using swapfiles on btrfs will lead to corruption, so we're avoiding the
problem for now by dropping bmap support entirely.  A later commit
will add fiemap support for people that really want to know how
a file is laid out.

Now that bmap support is gone, this is the only way to get extent
mappings for userland.  These are still not valid for IO, but they
can tell us if a file has holes or how much fragmentation there is.

Improve usbnet's devdbg to always type-check diagnostic arguments,
like dev_dbg (device.h).  This makes no change to the resulting size of
usbnet modules.

This patch also removes an #ifdef DEBUG directive from rndis_wlan so
it's devdbg statements are always type-checked at compile time.

mcs7830_set_reg() and mcs7830_get_reg() are called with buffers

This causes corruption of the stack particulary on non x86

Subject: [PATCH 0240/1079] dlm: initialize file_lock struct in GETLK before
 copying conflicting lock

dlm_posix_get fills out the relevant fields in the file_lock before
returning when there is a lock conflict, but doesn't clean out any of
the other fields in the file_lock.

When nfsd does a NFSv4 lockt call, it sets the fl_lmops to
nfsd_posix_mng_ops before calling the lower fs. When the lock comes back
after testing a lock on GFS2, it still has that field set. This confuses
nfsd into thinking that the file_lock is a nfsd4 lock.

Fix this by making DLM reinitialize the file_lock before copying the
fields from the conflicting lock.

Subject: [PATCH 0242/1079] Long btree pointers are still 64 bit on disk

[XFS] Long btree pointers are still 64 bit on disk

On 32 bit machines with CONFIG_LBD=n, XFS reduces the
in memory size of xfs_fsblock_t to 32 bits so that it
will fit within 32 bit addressing. However, the disk format
for long btree pointers are still 64 bits in size.

The recent btree rewrite failed to take this into account
when initialising new btree blocks, setting sibling pointers
to NULL and checking if they are NULL. Hence checking whether
a 64 bit NULL was the same as a 32 bit NULL was failingi
resulting in NULL sibling pointers failing to be detected
correctly. This showed up as WANT_CORRUPTED_GOTO shutdowns
in xfs_btree_delrec.

Fix this by making all the comparisons and setting of long
pointer btree NULL blocks to the disk format, not the
in memory format. i.e. use NULLDFSBNO.

Subject: [PATCH 0243/1079] drm: create mode_config idr lock

Create a separate mode_config IDR lock for simplicity.  The core DRM
config structures (connector, mode, etc. lists) are still protected by
the mode_config mutex, but the CRTC IDR (used for the various identifier
IDs) is now protected by the mode_config idr_mutex.  Simplifies the
locking a bit and removes a warning.

All objects are protected by the config mutex, we may in the future,
split the object further to have reference counts.

Subject: [PATCH 0245/1079] x86: unmask CPUID levels on Intel CPUs

Impact: Fixes crashes with misconfigured BIOSes on XSAVE hardware

Avuton Olrich reported early boot crashes with v2.6.28 and
bisected it down to dc1e35c6e95e8923cf1d3510438b63c600fee1e2
("x86, xsave: enable xsave/xrstor on cpus with xsave support").

If the CPUID limit bit in MSR_IA32_MISC_ENABLE is set, clear it to
make all CPUID information available.  This is required for some
features to work, in particular XSAVE.

Subject: [PATCH 0292/1079] Btrfs: do less aggressive btree readahead

Just before reading a leaf, btrfs scans the node for blocks that are
close by and reads them too.  It tries to build up a large window
of IO looking for blocks that are within a max distance from the top
and bottom of the IO window.

This patch changes things to just look for blocks within 64k of the
target block.  It will trigger less IO and make for lower latencies on
the read size.

Subject: [PATCH 0296/1079] rt2x00: Fix TX rate short preamble detection

Mac80211 provides 2 structures to handle bitrates, namely
ieee80211_rate and ieee80211_tx_rate. To determine the short preamble
mode for an outgoing frame, the flag IEEE80211_TX_RC_USE_SHORT_PREAMBLE
must be checked on ieee80211_tx_rate and not ieee80211_rate (which rt2x00 did).

This fixes a regression which was triggered in 2.6.29-rcX as reported by Chris Clayton.

If we let the firmware do the data encryption, we have to remove the ICV and

Or, these data frames have a few trailing bytes on cooked monitor interfaces.

Subject: [PATCH 0300/1079] p54usb: fix nasty use after free

In theory, the firmware acks the received a data frame, before signaling the driver to free it again.
However Artur Skawina <art.08.09@gmail.com> has shown that it can happen in reverse order as well.
This is very bad and could lead to memory corruptions, oopses and panics.

Thanks to Artur Skawina <art.08.09@gmail.com> for reporting and debugging this issue.

To avoid complications, make sure that the HW is in reset (as it should be)
before trying to take it out of reset. In normal flows, the HW is indeed in rest
so this should have no effect

Subject: [PATCH 0309/1079] bnx2x: loopback test failure

A link change interrupt might be queued and activated after the loopback was set
and it will cause the loopback to fail. The PHY lock should be kept until the
loopback test is over.

That implies that the bnx2x_test_link should used within the loopback function
and not bnx2x_wait_for_link since that function also takes the PHY link

Subject: [PATCH 0311/1079] phylib: Fix oops in suspend/resume paths

Suspend/resume routines check for phydrv != NULL, but that is
wrong because "phydrv" comes from container_of(drv). If drv is NULL,
then container_of(drv) will return non-NULL result, and the checks
won't work.

The Freescale TBI PHYs are driver-less, so "drv" is NULL, and that
leads to the following oops:

Unable to handle kernel paging request for data at address 0xffffffe4
Faulting instruction address: 0xc0215554

(sctp: Start T3-RTX timer when fast retransmitting lowest TSN)
introduced a regression where it was possible to forcibly
restart the sctp retransmit timer at the transmission of any
new chunk.  This resulted in much longer timeout times and
sometimes hung sctp connections.

Subject: [PATCH 0316/1079] sctp: Properly timestamp outgoing data chunks for
 rtx purposes

Recent changes to the retransmit code exposed a long standing
bug where it was possible for a chunk to be time stamped
after the retransmit timer was reset.  This caused a rare
situation where the retrnamist timer has expired, but
nothing was marked for retrnasmission because all of
timesamps on data were less then 1 rto ago.  As result,
the timer was never restarted since nothing was retransmitted,
and this resulted in a hung association that did couldn't
complete the data transfer.  The solution is to timestamp
the chunk when it's added to the packet for transmission
purposes.  After the packet is trsnmitted the rtx timer
is restarted.  This guarantees that when the timer expires,
there will be data to retransmit.

Subject: [PATCH 0317/1079] sctp: Fix another socket race during accept/peeloff

There is a race between sctp_rcv() and sctp_accept() where we
have moved the association from the listening socket to the
accepted socket, but sctp_rcv() processing cached the old
socket and continues to use it.

The easy solution is to check for the socket mismatch once we've
grabed the socket lock.  If we hit a mis-match, that means
that were are currently holding the lock on the listening socket,
but the association is refrencing a newly accepted socket.  We need
to drop the lock on the old socket and grab the lock on the new one.

A more proper solution might be to create accepted sockets when
the new association is established, similar to TCP.  That would
eliminate the race for 1-to-1 style sockets, but it would still
existing for 1-to-many sockets where a user wished to peeloff an
association.  For now, we'll live with this easy solution as
it addresses the problem.

Some revisions of the 92hd8xxx codec's not supporting port power
downs in which the using of it causes capture and also randomly
playback streams to not function at all. Thus by disabling it by
default and adding a option to enable it manually will fix all issue
on current and future revisions.

Subject: [PATCH 0320/1079] ALSA: hda - Fix PCM reference NID for STAC/IDT
 analog outputs

The reference NID for the analog outputs of STAC/IDT codecs is set
to a fixed number 0x02.  But this isn't always correct and in many
codecs it points to a non-existing NID.

This patch fixes the initialization of the PCM reference NID taken
from the actually probed DAC list.

Use the personality() macro to mask out all bits that are not
relevant for the personality type.
The personality field contains bits for other things as well,
so without masking out the not relevalent bits the comparison
won't do what is expected.

Subject: [PATCH 0326/1079] [S390] fix compat sigaltstack syscall table entry

When 31 bit user space programs call sigaltstack on a 64 bit Linux
OS, the system call returns -1 with errno=EFAULT. The 31 bit pointer passed
to the system call is extended to 64 bit, but the high order bits are not
set to zero. The kernel detects the invalid user space pointer and
returns -EFAULT. To solve the problem, sys32_sigaltstack_wrapper()
instead of sys32_sigaltstack() has to be called. The wrapper function sets
the high order bits to zero.

Subject: [PATCH 0327/1079] [S390] cputime: fix lowcore initialization on cpu
 hotplug

On (initial) cpu hotplug the lowcore values for user_timer and
system_timer don't get initialized like they would get on each
process schedule.
On initial start of secondary cpus this leads to the situation
where per thread user/system_timer values are larger than the
corresponding contents of the lowcore. When later calculating
time spent in user/system context the result can be negative.

So for cpu hotplug we should manually initialize lowcore values.

Fixes this bug:

Subject: [PATCH 0328/1079] [S390] etr/stp: fix possible deadlock

Precreate stop_machine threads in case the machine supports ETR/STP.
Otherwise we might deadlock if a time sync operation gets scheduled
and the creation of stop_machine threads would cause disk I/O.
This is just the minimal fix.
The real fix would be to only precreate stop_machine threads if
ETR/STP is actually used. But that would be a rather large and
complicated patch.

This is the case where a concurrent fault already installed the PTE and
we get to free the newly allocated one.

This is due to pgtable_page_ctor() doing the spin_lock_init(&page->ptl)
which is overlaid with the {private, mapping} struct.

union {
    struct {
        unsigned long private;
        struct address_space *mapping;
    };
    spinlock_t ptl;
    struct kmem_cache *slab;
    struct page *first_page;
};

Normally the spinlock is small enough to not stomp on page->mapping, but
PREEMPT_RT=y has huge 'spin'locks.

But lockdep kernels should also be able to trigger this splat, as the
lock tracking code grows the spinlock to cover page->mapping.

The obvious fix is calling pgtable_page_dtor() like the regular pte free
path __pte_free_tlb() does.

It seems all architectures except x86 and nm10300 already do this, and
nm10300 doesn't seem to use pgtable_page_ctor(), which suggests it
doesn't do SMP or simply doesnt do MMU at all or something.

Commit 1058a75f07b9bb8323fb5197be5526220f8b75cf ("xen: actually release
memory when shrinking domain") causes a crash if the page being released
is a highmem page.

If a page is highmem then there is no need to unmap it.

Subject: [PATCH 0333/1079] iwlwifi: fix rs_get_rate WARN_ON()

In ieee80211_sta structure there is u64 supp_rates[IEEE80211_NUM_BANDS]
this is filled with all support rate from assoc_resp.  If we associate
with G-band AP only supp_rates of G-band will be set the other band
supp_rates will be set to 0. If the user type this command
this will cause mac80211 to set to new channel, mac80211
does not disassociate in setting new channel, so the active
band is now A-band. then in handling the new essid mac80211 will
kick in the assoc steps which involve sending disassociation frame.
in this mac80211 will WARN_ON sta->supp_rates[A_BAND] == 0.

Subject: [PATCH 0336/1079] firewire: ohci: increase AT req. retries, fix
 ack_busy_X from Panasonic camcorders and others

Camcorders have a tendency to fail read requests to their config ROM and
write request to their FCP command register with ack_busy_X.  This has
become a problem with newer kernels and especially Panasonic camcorders,
causing AV/C in dvgrab and kino to fail.  Dvgrab for example frequently
logs "send oops"; kino reports loss of AV/C control.  I suspect that
lower CPU scheduling latencies in newer kernels made this issue more
prominent now.

According to
https://sourceforge.net/tracker/?func=detail&atid=114103&aid=2492640&group_id=14103
this can be fixed by configuring the FireWire controller for more
hardware retries for request transmission; these retries are evidently
more successful than libavc1394's own retry loop (typically 3 tries on
top of hardware retries).

Presumably the same issue has been reported at
https://bugzilla.redhat.com/show_bug.cgi?id=449252 and
https://bugzilla.redhat.com/show_bug.cgi?id=477279 .

In a quick test with a JVC camcorder (which didn't malfunction like the
reported camcorders), this change decreased the number of ack_busy_X
from 16 in three runs of dvgrab to 4 in three runs of the same capture
duration.

Subject: [PATCH 0343/1079] [ARM] clkdev: fix clock matching

The old matching algorithm was too fuzzy, causing false positives.
For example, when asked for device D connection C1 and we only find
device D connection C2, we return that as a valid match despite the
connection names being different.

Change the algorithm such that:
  An entry with a NULL ID is assumed to be a wildcard.
  If an entry has a device ID, it must match
  If an entry has a connection ID, it must match

However, we maintain the order of precidence while still only doing
a single pass over all entries: dev+con > dev only > con only.

Subject: [PATCH 0344/1079] [ARM] 5369/1: omap mmc: Add new omap hsmmc
 controller for 2430 and 34xx, v3

Add omap hsmmc controller for 2430 and 34xx.

Note that this controller has different registers compared to
the earlier omap MMC controller, so sharing code currently is
not possible.

Various updates and fixes from linux-omap list have been
merged into this patch.

The driver was updated for OMAP34xx, but the Kconfig file was missed.
So this adds the missing parts from d99241c in Tony Lindgren's tree:

    Add watchdog timer support for TI OMAP3430.

Subject: [PATCH 0347/1079] firewire: core: optimize card shutdown

This fixes a regression by "firewire: keep highlevel drivers attached
during brief connection loss":  There were 2 seconds unnecessary waiting
added to the shutdown procedure of each controller.

We use card->link as status flag to signal the device handler that there
is no use to wait for a come-back.

the locking functions obviously are more picky about their arguments.

Subject: [PATCH 0349/1079] [SCSI] libiscsi: fix iscsi pool leak

I am not sure what happened. It looks like we have always leaked
the q->queue that is allocated from the kfifo_init call. nab finally
noticed that we were leaking and this patch fixes it by adding a
kfree call to iscsi_pool_free. kfifo_free is not used per kfifo_init's
instructions to use kfree.

Subject: [PATCH 0350/1079] [SCSI] qla4xxx: do not reuse session when
 connecting to different target port

qla4xxx does not check the I_T nexus values correctly
so it ends up creating one session to the target. If
a portal should disappear or they should be reported
in different order the driver will think it is already
logged in when it could now be speaking to a different
target portal or accessing it through a different
initiator port (iscsi initiator port is not tied to
hardware and is just the initiator name plus isid
so you could end up with multiple ports through one
host).

This patch has the driver check the iscsi scsi port
values when matching sessions (we do not check
the initiator name because that is static). It results
in a portal from each target portal group getting
logged into instead of just one per target. In the future
the firmware should hopefully send us notification of other
sessions that are created to other portals within the
same tpgt and the sessions should have different isids.

Original code would incorrectly bypass serialization if the DPC

secondary thread's mailbox command execution.  Found during

 precedence for ISP81XX parts.

Pre-ISP81XX parts (including ISP24xx and ISP25xx) could contain a
firmware image within a segment of flash, driver would fallback
to loading this firmware if the request-firmware interface failed
(userspace .bin file).  Moving forward, all ISP81XX parts will
ship with a suggested-to-be-used firmware image within flash
which all driver should first attempt to load.  If the flash
firmware load fails, the driver will then fallback to loading
firmware via the request-firmware interface (ql8100_fw.bin).

Subject: [PATCH 0359/1079] [SCSI] qla2xxx: Correct descriptions in flash
 manipulation routines.

When clearing the flash device's SR, the comment is incorrect...
clearing the SR is 2 steps:

1. the SR protect bit is 1, so the first write zero clears only
   that bit,

2. the SR protect bit is now 0, so the next write zero clears the
   remaining bits.

The sector erase debug print more correctly identifies that the erase failed.

Jeremy Higdon noted
(http://marc.info/?l=linux-scsi&m=123262143131788&w=2) that the
rework done in commit e315cd28b9ef0d7b71e462ac16e18dbaa2f5adfe
was not setting the proper consistent and streaming DMA masks
prior to memory allocations.  Correct this and remove the
unnecessary prototype.

changed the callback semantics of dev_loss_tmo and
terminate_rport_io such that repeated calls could be made.  This
could result in the the driver using stale (NULLed-out, in
dev_loss_tmo) data from the rport.  Correct this by addint a
simple check to ensure a valid fcport is attached.

 allocation failure

There is currently a DMA mapping leak that can occur in the ibmvfc
driver if we fail to allocate a scatterlist. Fix this by unmapping
the scatterlist in the failure path. Additionally, only log an error
for a scatterlist allocation failure if the log level is greater
than the default, since this can occur when running Active Memory
Sharing and this is not considered an error.

Subject: [PATCH 0364/1079] x86: use standard PIT frequency

the RDC and ELAN platforms use slighly different PIT clocks, resulting in
a timex.h hack that changes PIT_TICK_RATE during build time. But if a
tester enables any of these platform support .config options, the PIT
will be miscalibrated on standard PC platforms.

So use one frequency - in a subsequent patch we'll add a quirk to allow
x86 platforms to define different PIT frequencies.

Subject: [PATCH 0365/1079] [ARM] fix section-based ioremap

Tomi Valkeinen reports:
  Running with latest linux-omap kernel on OMAP3 SDP board, I have
  problem with iounmap(). It looks like iounmap() does not properly
  free large areas. Below is a test which fails for me in 6-7 loops.

	for (i = 0; i < 200; ++i) {
		vaddr = ioremap(paddr, size);
		if (!vaddr) {
			printk("couldn't ioremap\n");
			break;
		}
		iounmap(vaddr);
	}

The changes to vmalloc.c weren't reflected in the ARM ioremap
implementation.  Turns out the fix is rather simple.

 VLANs

802.1Q expanded the maximum ethernet frame size by 4 bytes for the
VLAN tag.  We're not taking this into account in virtio_net, which
means the buffers we provide to the backend in the virtqueue RX ring
aren't big enough to hold a full MTU VLAN packet.  For QEMU/KVM,
this results in the backend exiting with a packet truncation error.

Subject: [PATCH 0369/1079] af_key: initialize xfrm encap_oa

Currently encap_oa is left uninitialized, so it contains garbage data which
is visible to userland via Netlink. Initialize it by zeroing it out.

Subject: [PATCH 0370/1079] x86: work around PAGE_KERNEL_WC not getting WC in
 iomap_atomic_prot_pfn.

In the absence of PAT, PAGE_KERNEL_WC ends up mapping to a memory type that
gets UC behavior even in the presence of a WC MTRR covering the area in
question.  By swapping to PAGE_KERNEL_UC_MINUS, we can get the actual
behavior the caller wanted (WC if you can manage it, UC otherwise).

This recovers the 40% performance improvement of using WC in the DRM
to upload vertex data.

This patch simplifies lock_[23]_inodes functions. We do not have
to care about locking order, because UBIFS does this for @i_mutex
and this is enough. Thanks to Al Viro for suggesting this.

When freeing the c->idx_lebs list, we have to release the LEBs as well,
because we might be called from mount to read-only mode code. Otherwise
the LEBs stay taken forever, which may cause problems when we re-mount
back ro RW mode.

From b4978e949104844224ecf786170c9263efa601f3 Mon Sep 17 00:00:00 2001
From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
Date: Fri, 23 Jan 2009 18:23:03 +0200
Subject: [PATCH 0374/1079] UBIFS: always clean up GC LEB space

When we mount UBIFS, GC LEB may contain out-of-date information,
and UBIFS should update lprops and set free space for thei LEB.
Currently UBIFS does this only if mounted R/W. But for R/O mount
we have to do the same, because otherwise we will have incorrect
FS free space reported to user-space.

Subject: [PATCH 0375/1079] UBIFS: ensure orphan area head is initialized

When mounting read-only the orphan area head is
not initialized.  It must be initialized when
remounting read/write, but it was not.  This patch
fixes that.

Subject: [PATCH 0377/1079] x86: unmask CPUID levels on Intel CPUs, fix

Impact: fix boot hang on pre-model-15 Intel CPUs

rdmsrl_safe() does not work in very early bootup code yet, because we
dont have the pagefault handler installed yet so exception section
does not get parsed. rdmsr_safe() will just crash and hang the bootup.

So limit the MSR_IA32_MISC_ENABLE MSR read to those CPU types that
support it.

Subject: [PATCH 0378/1079] libata: set NODEV_HINT for 0x7f status

Asus Pundit-R with atiixp controller has the second port missing and,
very unusually, its status is stuck at 0x7f and all others at 0.  This
meanst that it fails TF access test but gets detected as a disk due to
classification code check and then evades polling IDENTIFY presence
detection thanks to the missing BSY in the status value causing
excessive delays during boot.

This patch makes libata-sff HSM set NODEV_HINT if the status is 0x7f
to make polling IDENTIFY presence detection work for these machines.

Subject: [PATCH 0380/1079] sata_nv: fix MCP5x reset

MCP5x family of controllers seem to share much more with nf2's as far
as reset protocol is concerned.  It requires heardreset to get the PHY
going and classfication code report after hardreset is unreliable.
Create a new board type MCP5x and use noclassify hardreset.  SWNCQ is
modified to inherit from this new type.

This fixes hotplug regression reported in kernel bz#12351.

Subject: [PATCH 0381/1079] sata_mv: fix 8-port timeouts on 508x/6081 chips

Fix a longstanding bug for the 8-port Marvell Sata controllers (508x/6081),
where accesses to the upper 4 ports would cause lost-interrupts / timeouts
for the lower 4-ports.  With this patch, the 6081 boards should finally be
reliable enough for mainstream use with Linux.

Remove silly read-modify-write sequences when clearing interrupts
in hc_irq_cause.  This gets rid of unneeded MMIO reads, resulting in
a slight performance boost when switching between EDMA and non-EDMA
modes (eg. for cache flushes).

Subject: [PATCH 0384/1079] sata_mv: Properly initialize main irq mask

I noticed that during initialization sata_mv.c assumes that the main
interrupt mask has its default value of 0. The function
mv_platform_probe(..) initializes a shadow irq mask with 0 assuming
that's the value of the controller's register. Now
mv_set_main_irq_mask(..) only writes the controller's register if the
new value differs from the "shadowed" value. This is fatal when trying
to disable all interrupts in mv_init_host(..), i.e. the following
function call does not write anything to the main irq mask register:

  mv_set_main_irq_mask(host, ~0, 0);

The effect I see on my machine (QNAP TS-109 II) with booting via kexec
(with Linux as a 2nd-stage boot loader) is that if the sata_mv module
was still loaded when performing kexec, then the new kernel's sata_mv
module starts up with interrupts enabled. This results in an unhandled
IRQ and breaks the boot process.

The unhandled interrupt itself might also be fixed by Lennert's patch
proposed at http://markmail.org/message/kwvzxstnlsa3s26w which I did not
try yet.

However I still propose to additionally initialize the shadow variable
with the current contents of the main irq mask register to get both in
sync and allow proper disabling the main irq mask. This fixes the
unhandled irq on my machine.

Subject: [PATCH 0388/1079] x86: fix section mismatch warning

Here function vmi_activate calls a init function activate_vmi , which
causes the following section mismatch warnings:

  LD      arch/x86/kernel/built-in.o
WARNING: arch/x86/kernel/built-in.o(.text+0x13ba9): Section mismatch
in reference from the function vmi_activate() to the function
.init.text:vmi_time_init()
The function vmi_activate() references
the function __init vmi_time_init().
This is often because vmi_activate lacks a __init
annotation or the annotation of vmi_time_init is wrong.

WARNING: arch/x86/kernel/built-in.o(.text+0x13bd1): Section mismatch
in reference from the function vmi_activate() to the function
.devinit.text:vmi_time_bsp_init()
The function vmi_activate() references
the function __devinit vmi_time_bsp_init().
This is often because vmi_activate lacks a __devinit
annotation or the annotation of vmi_time_bsp_init is wrong.

WARNING: arch/x86/kernel/built-in.o(.text+0x13bdb): Section mismatch
in reference from the function vmi_activate() to the function
.devinit.text:vmi_time_ap_init()
The function vmi_activate() references
the function __devinit vmi_time_ap_init().
This is often because vmi_activate lacks a __devinit
annotation or the annotation of vmi_time_ap_init is wrong.

Fix it by marking vmi_activate() as __init too.

Subject: [PATCH 0393/1079] fuse: destroy bdi on umount

If a fuse filesystem is unmounted but the device file descriptor
remains open and a new mount reuses the old device number, then the
mount fails with EEXIST and the following warning is printed in the
kernel log:

  WARNING: at fs/sysfs/dir.c:462 sysfs_add_one+0x35/0x3d()
  sysfs: duplicate filename '0:15' can not be created

The cause is that the bdi belonging to the fuse filesystem was
destoryed only after the device file was released.  Fix this by
calling bdi_destroy() from fuse_put_super() instead.

Subject: [PATCH 0394/1079] fuse: fix poll notify

Move fuse_copy_finish() to before calling fuse_notify_poll_wakeup().
This is not a big issue because fuse_notify_poll_wakeup() should be
atomic, but it's cleaner this way, and later uses of notification will
need to be able to finish the copying before performing some actions.

As far as I am capable of discerning from the documentation,
MSR_IA32_MISC_ENABLE should be available for all family 0xf CPUs, as
well as family 6 for model >= 0xd (newer Pentium M).

The documentation on this isn't ideal, so we need to be on the lookout
for errors, still.

Subject: [PATCH 0398/1079] inotify: clean up inotify_read and fix locking
 problems

If userspace supplies an invalid pointer to a read() of an inotify
instance, the inotify device's event list mutex is unlocked twice.
This causes an unbalance which effectively leaves the data structure
unprotected, and we can trigger oopses by accessing the inotify
instance from different tasks concurrently.

The best fix (contributed largely by Linus) is a total rewrite
of the function in question:

Subject: [PATCH 0399/1079] m68k{nommu}: fixups after the header move

swab.h seems to have been missed during the header merge.
Add conditionals similar to byteorder.h and remove the
now unnecessary byteorder_no/mm.h

Subject: [PATCH 0400/1079] e1000e: workaround hw errata

There is a hardware errata in some revisions of the 82574 that needs
to be worked around in the driver by setting a register bit at init.

If this bit is not set A0 versions of the 82574 can generate
tx hangs.

Subject: [PATCH 0404/1079] i2c: Quilt tree has moved

My i2c quilt tree will now be hosted on kernel.org, because I can
conveniently use rsync there.

Also list the new i2c wiki.

Subject: [PATCH 0405/1079] i2c: Move at24 to drivers/misc/eeprom

As drivers/i2c/chips is going to go away, move the driver to
drivers/misc/eeprom. Other eeprom drivers may be moved here later, too.
Update Kconfig text to specify this driver as I2C.

Subject: [PATCH 0409/1079] eeprom: More consistent symbol names

Now that all EEPROM drivers live in the same place, let's harmonize
their symbol names.

Also fix eeprom's dependencies, it definitely needs sysfs, and is no
longer experimental after many years in the kernel tree.

Subject: [PATCH 0410/1079] i2c: Warn on deprecated binding model use

Let the kernel developers know that i2c_attach_client() and
i2c_detach_client() are deprecated and should no longer be used.
Drivers using these should be converted to the standard device
driver binding model (probe and remove methods.)

The following patch fixes a warning caused by a missing ifdef in
isdn_ppp.c. A function was defined, but never used if CONFIG_IPPP_FILTER
was not defined.

The warning was: 'get_filter' defined but not used
Patch is against 2.6.28.1

Subject: [PATCH 0416/1079] bnx2x: tx_has_work should not wait for FW

The current tx_has_work waited until all packets sent by the driver
are marked as completed by the FW. This is too greedy and it causes
the bnx2x_poll to spin in vain. The driver should only check that all
packets FW already completed are freed - only in unload flow the
driver should make sure that transmit queue is empty

Subject: [PATCH 0417/1079] vlan: Export symbols as non GPL symbols.

In previous kernels, any kernel module could get access to the
'real-device' and the VLAN-ID for a particular VLAN.  In more recent
kernels, the code was restructured such that this is hard to do
without accessing private .h files for any module that cannot use
GPL-only symbols.

Attached is a patch to once again allow non-GPL modules the ability to
access the real-device and VLAN id for VLANs.

Subject: [PATCH 0419/1079] gianfar: Revive VLAN support

commit 77ecaf2d5a8bfd548eed3f05c1c2e6573d5de4ba ("gianfar: Fix VLAN
HW feature related frame/buffer size calculation") wrongly removed
priv->vlgrp assignment, and now priv->vlgrp is always NULL.

This patch fixes the issue, plus fixes following sparse warning
introduced by the same commit:
gianfar.c:1406:13: warning: context imbalance in 'gfar_vlan_rx_register' - wrong count at exit

gfar_vlan_rx_register() checks for "if (old_grp == grp)" and tries
to return w/o dropping the lock.

According to net/8021q/vlan.c VLAN core issues rx_register() callback:
1. In register_vlan_dev() only on a newly created group;
2. In unregister_vlan_dev() only if the group becomes empty.

Thus the check in the gianfar driver isn't needed.

Subject: [PATCH 0420/1079] signals, debug: fix BUG: using smp_processor_id()
 in preemptible code in print_fatal_signal()

With print-fatal-signals=1 on a kernel with CONFIG_PREEMPT=y, sending an
unexpected signal to a process causes a BUG: using smp_processor_id() in
preemptible code.

get_signal_to_deliver() releases the siglock before calling
print_fatal_signal(), which calls show_regs(), which calls
smp_processor_id(), which is not supposed to be called from a
preemptible thread.

Make sure show_regs() runs with preemption disabled.

Subject: [PATCH 0422/1079] ext4: Fix building with EXT4FS_DEBUG

When bg_free_blocks_count was renamed to bg_free_blocks_count_lo in
560671a0, its uses under EXT4FS_DEBUG were not changed to the helper
ext4_free_blks_count.

Another commit, 498e5f24, also did not change everything needed under
EXT4FS_DEBUG, thus making it spill some warnings related to printing
format.

This commit fixes both issues and makes ext4 build again when
EXT4FS_DEBUG is enabled.

introduce stub for debugfs_create_size_t() when DEBUG_FS=n") and due to

Subject: [PATCH 0429/1079] virtio_net: use correct accessors for scatterlists

Without this fix, virtio_net makes incorrect usage of scatterlists. It sets
the end of the scatterlist chain after the first element, despite the fact
that more entries come after it.

If you try to run dma_map_sg() on one of the scatterlists given to you by
add_buf(), you will get a null pointer oops.

Subject: [PATCH 0430/1079] udp: optimize bind(0) if many ports are in use

commit 9088c5609584684149f3fb5b065aa7f18dcb03ff
(udp: Improve port randomization) introduced a regression for UDP bind() syscall
to null port (getting a random port) in case lot of ports are already in use.

This is because we do about 28000 scans of very long chains (220 sockets per chain),
with many spin_lock_bh()/spin_unlock_bh() calls.

Fix this using a bitmap (64 bytes for current value of UDP_HTABLE_SIZE)
so that we scan chains at most once.

Instead of 250 ms per bind() call, we get after patch a time of 2.9 ms

Based on a report from Vitaly Mayatskikh

 walk_done

When we get left-over bits from a slow walk, it means that the
underlying cipher has gone troppo.  However, as we're handling
that case we should ensure that the caller terminates the walk.

This patch does this by setting walk->nbytes to zero.

Its a valid use case to have null associated data in a ccm vector, but
this case isn't being handled properly right now.

The following ccm decryption/verification test vector, using the
rfc4309 implementation regularly triggers a panic, as will any
other vector with null assoc data:

* key: ab2f8a74b71cd2b1ff802e487d82f8b9
* iv: c6fb7d800d13abd8a6b2d8
* Associated Data: [NULL]
* Tag Length: 8
* input: d5e8939fc7892e2b

The resulting panic looks like so:

The above is from a RHEL5-based kernel, but upstream is susceptible too.

The fix is trivial: in crypto/ccm.c:crypto_ccm_auth(), pctx->ilen contains
whatever was in memory when pctx was allocated if assoclen is 0. The tested
fix is to simply add an else clause setting pctx->ilen to 0 for the
assoclen == 0 case, so that get_data_to_compute() doesn't try doing
things its not supposed to.

Subject: [PATCH 0434/1079] tcp: Fix length tcp_splice_data_recv passes to
 skb_splice_bits.

tcp_splice_data_recv has two lengths to consider: the len parameter it
gets from tcp_read_sock, which specifies the amount of data in the skb,
and rd_desc->count, which is the amount of data the splice caller still
wants.  Currently it passes just the latter to skb_splice_bits, which then
splices min(rd_desc->count, skb->len - offset) bytes.

Most of the time this is fine, except when the skb contains urgent data.
In that case len goes only up to the urgent byte and is less than
skb->len - offset.  By ignoring len tcp_splice_data_recv may a) splice
data tcp_read_sock told it not to, b) return to tcp_read_sock a value > len.

Now, tcp_read_sock doesn't handle used > len and leaves the socket in a
bad state (both sk_receive_queue and copied_seq are bad at that point)
resulting in duplicated data and corruption.

Fix by passing min(rd_desc->count, len) to skb_splice_bits.

Subject: [PATCH 0435/1079] m68knommu: use one exist from execption

Part of the code that did not make sense to me got removed by Greg.
This is part two:

The first compare is to check whether the interrupts are disabled or not.
Depending on the result we exectute the RESTORE_ALL macro is not only
restoring the stack but also returning to caller.
The test for pending softirq has been removed because it is allready done
in irq_exit().
Since system_call() is allso using the SAVE_ALL macro and returning via
ret_from_exception label I see no reason why we could not do this here
as well. This is also handy because if we return from the timer interrupt
and we need to resched than we check for this :)

Subject: [PATCH 0436/1079] m68knommu: fix ColdFire 5272 serial baud rates in
 mcf.c

I noticed (the hard way) that the mcf.c driver doesn't support the fractional precision register on the MCF5272.  This makes the console dicey at 115200 baud and a system clock of 66.0 MHz.  On the other hand, if your hardware is running at 66.666 MHz, it probably isn't a problem.

Patch submitted by John Adamson <jadamson@allen-organ.com>

Subject: [PATCH 0437/1079] m68knommu: fix cache flushing for the 527x ColdFire
 processors

Fix cache flushing for the 527x ColdFire processors
Its CACR register format is slightly different.

Along with this add support for flushing the 523x cache, which uses
the same format as the 527x ColdFire's, and was missing flush support.

Subject: [PATCH 0448/1079] Hibernation: Introduce system_entering_hibernation

Introduce boolean function system_entering_hibernation() returning
'true' during the last phase of hibernation, in which devices are
being put into low power states and the sleep state (for example,
ACPI S4) is finally entered.

Some device drivers need such a function to check if the system is
in the final phase of hibernation.  In particular, some SATA drivers
are going to use it for blacklisting systems in which the disks
should not be spun down during the last phase of hibernation (the
BIOS will do that anyway).

Subject: [PATCH 0449/1079] DMI: Introduce dmi_first_match to make the
 interface more flexible

Some notebooks from HP have the problem that their BIOSes attempt to
spin down hard drives before entering ACPI system states S4 and S5.
This leads to a yo-yo effect during system power-off shutdown and the
last phase of hibernation when the disk is first spun down by the
kernel and then almost immediately turned on and off by the BIOS.
This, in turn, may result in shortening the disk's life times.

To prevent this from happening we can blacklist the affected systems
using DMI information.  However, only the on-board controlles should
be blacklisted and their PCI slot numbers can be used for this
purpose.  Unfortunately the existing interface for checking DMI
information of the system is not very convenient for this purpose,
because to use it, we would have to define special callback functions
or create a separate struct dmi_system_id table for each blacklisted
system.

To overcome this difficulty introduce a new function
dmi_first_match() returning a pointer to the first entry in an array
of struct dmi_system_id elements that matches the system DMI
information.  Then, we can use this pointer to access the entry's
.driver_data field containing the additional information, such as
the PCI slot number, allowing us to do the desired blacklisting.

Introduce new libata flags ATA_FLAG_NO_POWEROFF_SPINDOWN and
ATA_FLAG_NO_HIBERNATE_SPINDOWN that, if set, will prevent disks from
being spun off during system power off and hibernation, respectively
(to handle the hibernation case we need the new system state
SYSTEM_HIBERNATE_ENTER that can be checked against by libata, in
analogy with SYSTEM_POWER_OFF).

Subject: [PATCH 0451/1079] SATA AHCI: Blacklist system that spins off disks
 during ACPI power off

Some notebooks from HP have the problem that their BIOSes attempt to
spin down hard drives before entering ACPI system states S4 and S5.
This leads to a yo-yo effect during system power-off shutdown and the
last phase of hibernation when the disk is first spun down by the
kernel and then almost immediately turned on and off by the BIOS.
This, in turn, may result in shortening the disk's life times.

To prevent this from happening we can blacklist the affected systems
using DMI information.

Blacklist HP nx6310 that uses the AHCI driver.

Subject: [PATCH 0456/1079] UBIFS: fix no_chk_data_crc

When data CRC checking is disabled, UBIFS returns incorrect return
code from the 'try_read_node()' function (0 instead of 1, which means
CRC error), which make the caller re-read the data node again, but using
a different code patch, so the second read is fine. Thus, we read the
same node twice. And the result of this is that UBIFS is slower
with no_chk_data_crc option than it is with chk_data_crc option.
This patches fixes the problem.

Subject: [PATCH 0458/1079] tty_open can return to userspace holding tty_mutex

__tty_open could return (to userspace) holding the tty_mutex thanks to a
regression introduced by 4a2b5fddd53b80efcb3266ee36e23b8de28e761a ("Move
tty lookup/reopen to caller").

This was found by bisecting an fsfuzzer problem.  Admittedly I have no
idea how it managed to tickle this 100% reliably, but it is clearly a
regression and when hit leaves the box in a completely unusable state.
This patch lets the fsfuzzer test complete every time.

Subject: [PATCH 0462/1079] PCI PM: Fix suspend error paths and testing
 facility breakage

If one of device drivers refuses to suspend by returning error code
from its ->suspend() callback, the devices that have already been
suspended are resumed by executing their drivers' ->resume()
callbacks.  Some of these callbacks expect the device's
configuration space to be restored if the device has been put into
D3 before they are called.  Unfortunately, this mechanism has been
broken by recent changes moving the restoration of config spaces
of some devices (most importantly, USB controllers and HDA Intel)
into the resume callbacks executed with interrupts off.  Obviously,
these callbacks are not invoked in the suspend error path and, as a
result, the system cannot be successfully brought back into the
working state in case of a suspend error.  The same thing happens
in the hibernation error path right before putting the system into
S4.

Similarly, the suspend testing facility associated with the
/sys/power/pm_test file is broken, because it uses the very same
mechanism that is used in the suspend and hibernation error paths.

Fix the breakage by making the PCI core restore the configuration
spaces of PCI devices that haven't been restored already before
pci_pm_resume() is called for those devices by the PM core.

Subject: [PATCH 0465/1079] PCI PM: Power up devices before restoring their
 state

Devices that have MSI-X enabled before suspend to RAM or hibernation
and that are in a low power state during resume will not be handled
correctly by pci_restore_standard_config().  Namely, it first calls
pci_restore_state() which calls pci_restore_msi_state(), which in turn
executes __pci_restore_msix_state() that accesses the device's memory
space to restore the contents of the MSI-X table.  However, if the
device is in a low power state at this point, it's memory space is
not accessible.

The easiest way to fix this potential problem is to make
pci_restore_standard_config() call pci_restore_state() after
it has put the device into the full power state, D0.  Fortunately,
all of this is done with interrupts off, so the change of ordering
should not cause any trouble.

Subject: [PATCH 0466/1079] PCI PM: Do not wait for buses in B2 or B3 during
 resume

pci_restore_standard_config() adds extra delay for PCI buses in
low power states (B2 or B3), but this is only correct for buses in
B2, because the buses in B3 are reset when they are put back into
B0.  Thus we should wait for such buses to settle after the reset,
but it's not a good idea to wait that long (1.1 s) with interrupts
off.

On the other hand, we have never waited for buses in B2 and B3
during resume and it seems reasonable to go back to this well
tested behaviour.

Subject: [PATCH 0468/1079] PCI hotplug: fakephp: Allocate PCI resources before
 adding the device

For PCI devices, pci_bus_assign_resources() must be called to set up the
pci_device->resource array before pci_bus_add_devices() can be called, else
attempts to load drivers results in BAR collision errors where there are none.
This is not done in fakephp, so devices can be "unplugged" but scanning the
parent bus won't bring the devices back due to resource unallocation.  Move the
pci_bus_add_device-calling logic into pci_rescan_bus and preface it with a call
to pci_bus_assign_resources so that we only have to (re)allocate resources once
per bus where a new device is found.

Subject: [PATCH 0470/1079] kmalloc: return NULL instead of link failure

The SLAB kmalloc with a constant value isn't consistent with the other
implementations because it bails out with __you_cannot_kmalloc_that_much
rather than returning NULL and properly allowing the caller to fall back
to vmalloc or take other action.  This doesn't happen with a non-constant
value or with SLOB or SLUB.

Starting with 2.6.28, I've been seeing build failures on s390x.  This is
due to init_section_page_cgroup trying to allocate 2.5MB when the max size
for a kmalloc on s390x is 2MB.

It's failing because the value is constant.  The workarounds at the call
size are ugly and the caller shouldn't have to change behavior depending
on what the backend of the API is.

So, this patch eliminates the link failure and returns NULL like the other
implementations.

Subject: [PATCH 0475/1079] nfsd: only set file_lock.fl_lmops in nfsd4_lockt if
 a stateowner is found

nfsd4_lockt does a search for a lockstateowner when building the lock
struct to test. If one is found, it'll set fl_owner to it. Regardless of
whether that happens, it'll also set fl_lmops. Given that this lock is
basically a "lightweight" lock that's just used for checking conflicts,
setting fl_lmops is probably not appropriate for it.

This behavior exposed a bug in DLM's GETLK implementation where it
wasn't clearing out the fields in the file_lock before filling in
conflicting lock info. While we were able to fix this in DLM, it
still seems pointless and dangerous to set the fl_lmops this way
when we may have a NULL lockstateowner.

Subject: [PATCH 0476/1079] PCI hotplug: Change link order of pciehp & acpiphp

Some hardware exposes PCIE slots in such a way that they can be claimed
by either the acpiphp or pciehp driver. pciehp is the preferred driver
if the firmware allows the OS to claim control via the _OSC method so
should be loaded first - if it fails to bind (either due to a missing
_OSC method or the firmware refusing to hand off control) then we can
fall back to acpiphp or a vendor-specific driver.

This patch simply changes the link order to ensure that pciehp will be
initialised before acpiphp if both are statically built into the kernel.

Move the initialization of irq_default_affinity to early_irq_init as
core_initcall is too late.

irq_default_affinity can be used in init_IRQ and potentially timer and
SMP init as well.  All of these happen before core_initcall.  Moving
the initialization to early_irq_init ensures that it is initialized
before it is used.

Subject: [PATCH 0481/1079] USB: fix toggle mismatch in disable_endpoint paths

This patch (as1200) finishes some fixes that were left incomplete by
an earlier patch.

Although nobody has addressed this issue in the past, it turns out
that we need to distinguish between two different modes of disabling
and enabling endpoints.  In one mode only the data structures in
usbcore are affected, and in the other mode the host controller and
device hardware states are affected as well.

The earlier patch added an extra argument to the routines in the
enable_endpoint pathways to reflect this difference.  This patch adds
corresponding arguments to the disable_endpoint pathways.  Without
this change, the endpoint toggle state can get out of sync between
the host and the device.  The exact mechanism depends on the details
of the host controller (whether or not it stores its own copy of the
toggle values).

Subject: [PATCH 0483/1079] USB: don't enable wakeup by default for PCI host
 controllers

This patch (as1199) changes the initial wakeup settings for PCI USB
host controllers.  The controllers are marked as capable of waking the
system, but wakeup is not enabled by default.

It turns out that enabling wakeup for USB host controllers has a lot
of bad consequences.  As the simplest example, if a USB mouse or
keyboard is unplugged immediately after the computer is put to sleep,
the unplug will cause the system to wake back up again!  We are better
off marking them as wakeup-capable and leaving wakeup disabled.

Subject: [PATCH 0484/1079] USB: Fix suspend-resume of PCI USB controllers

Commit a0d4922da2e4ccb0973095d8d29f36f6b1b5f703
(USB: fix up suspend and resume for PCI host controllers) attempted
to fix the suspend-resume of PCI USB controllers, but unfortunately
it did that incorrectly and interrupts are left enabled by the USB
controllers' ->suspend_late() callback as a result.  This leads to
serious problems during suspend which are very difficult to debug.

Fix the issue by removing the ->suspend_late() callback of PCI
USB controllers and moving the code from there to the ->suspend()
callback executed with interrupts enabled.  Additionally, make
the ->resume() callback of PCI USB controllers execute
pci_enable_wake(dev, PCI_D0, false) to disable wake-up from the
full power state (PCI_D0).

Subject: [PATCH 0485/1079] USB: fix char-device disconnect handling

This patch (as1198) fixes a conceptual bug: Somewhere along the line
we managed to confuse USB class devices with USB char devices.  As a
result, the code to send a disconnect signal to userspace would not be
built if both CONFIG_USB_DEVICE_CLASS and CONFIG_USB_DEVICEFS were
disabled.

The usb_fs_classdev_common_remove() routine has been renamed to
usbdev_remove() and it is now called whenever any USB device is
removed, not just when a class device is unregistered.  The notifier
registration and unregistration calls are no longer conditionally
compiled.  And since the common removal code will always be called as
part of the char device interface, there's no need to call it again as
part of the usbfs interface; thus the invocation of
usb_fs_classdev_common_remove() has been taken out of
usbfs_remove_device().

Subject: [PATCH 0491/1079] USB: musb uses endpoint functions

This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

An extract of the semantic patch that makes these changes is as follows:
(http://www.emn.fr/x-info/coccinelle/)

Subject: [PATCH 0496/1079] USB: composite: Fix bug: low byte of w_index is the
 usb interface number not the whole 2 bytes of w_index

In some usb gadget driver, for example usb audio class device, the high
byte of w_index is the entity id and low byte is the interface number.
If we use the 2 bytes of w_index as the array number, we will get a
wrong pointer or NULL pointer.

This patch fixes this issue.

This patch adds a device quirk for a MediaTek Inc GPS chipset. The

the ACM class driver fails to probe the device.

I've tested this patch with an iBlue A+ GPS which uses this chipset
and using kernel 2.6.28-rc9.

Subject: [PATCH 0500/1079] USB: usblp.c: add USBLP_QUIRK_BIDIR to Brother
 HL-1440

My Brother HL-1440 would print one document before CUPS would stop
printing with the error "Printer not connected; will retry in 30
seconds...". I traced this down to the CUPS usb backend getting an EIO
out of usblp on the IOCNR_GET_DEVICE_ID IOCTL. Adding the
USBLP_QUIRK_BIDIR fixes the problem but is it the right solution?

output from strace /usr/lib/cups/backend/usb after printing a document
(Note: SNDCTL_DSP_SYNC == IOCNR_GET_DEVICE_ID):

before patch

open("/dev/usb/lp0", O_RDWR|O_EXCL)     = 3
ioctl(3, SNDCTL_DSP_SYNC, 0x7fff2478cef0) = -1 EIO (Input/output error)

after patch

open("/dev/usb/lp0", O_RDWR|O_EXCL)     = 3
ioctl(3, SNDCTL_DSP_SYNC, 0x7fffb8d474c0) = 0

Subject: [PATCH 0505/1079] USB: usbmon: Implement compat_ioctl

Running a 32-bit usbmon(8) on 2.6.28-rc9 produces the following:
ioctl32(usbmon:28563): Unknown cmd fd(3) cmd(400c9206){t:ffffff92;sz:12} arg(ffd3f458) on /dev/usbmon0

It happens because the compatibility mode was implemented for 2.6.18
and not updated for the fsops.compat_ioctl API.

This patch relocates the pieces from under #ifdef CONFIG_COMPAT into
compat_ioctl with no other changes except one new whitespace.

Subject: [PATCH 0507/1079] USB: Remove ZTE modem from unusual_devices

The ZTE modem entry causes usb-storage to ignore the device, but for some
versions of the device, usb-storage mode is required to get to modem ode. For
both kinds the tool: http://www.draisberghof.de/usb_modeswitch/ should work.

Note that the various versions of the device have the same ProductId,
VendorId, and bcdDevice number, so we cannot have the entry for some and not
others.

While trying to make GSM modem Onda MT503HS working, I found a mismatch
between device id in the driver code (0x0200) and id in the lsusb
output (0x2000).

This patch fixed it for me, but I don't know if the original device id was
also correct and the new ID should be added instead of replacing the
old one.

Subject: [PATCH 0512/1079] USB: unusual_dev: usb-storage needs to ignore a
 device

This patch adds an unusual_devs entry for a Sony Ericsson modem. Like many
other modems, we have to ignore the storage device in order to access the
modem.


At this time usb_modeswitch does not work with this device.

Subject: [PATCH 0515/1079] USB: Driver for Freescale QUICC Engine USB Host
 Controller

This patch adds support for the FHCI USB controller, as found
in the Freescale MPC836x and MPC832x processors. It can support
Full or Low speed modes.

Quite a lot the hardware is doing by itself (SOF generation, CRC
generation and checking), though scheduling and retransmission is on
software's shoulders.

This controller does not integrate the root hub, so this driver also
fakes one-port hub. External hub is required to support more than
one device.

Subject: [PATCH 0516/1079] e1000: fix bug with shared interrupt during reset

A nasty bug was found where an MTU change (or anything else that caused a
reset) could race with the interrupt code.  The interrupt code was entered
by a shared interrupt during the MTU change.

This change prevents the interrupt code from running while the driver is in
the middle of its reset path.

Subject: [PATCH 0517/1079] net: wrong test in inet_ehash_locks_alloc()

In commit 9db66bdcc83749affe61c61eb8ff3cf08f42afec (net: convert
TCP/DCCP ehash rwlocks to spinlocks), I forgot to change one
occurrence of rwlock_t to spinlock_t

I believe sizeof(raw_spinlock_t) might be > 0 on !CONFIG_SMP if
CONFIG_DEBUG_SPINLOCK while sizeof(raw_rwlock_t) should be 0 in this
case.

Fortunatly, CONFIG_DEBUG_SPINLOCK adds fields to both spinlock_t and
rwlock_t, but at this might change in the future (being able to debug
spinlocks but not rwlocks for example), better to be safe.

Subject: [PATCH 0518/1079] smackfs load append mode fix

Given just how hard it is to find the code that uses MAY_APPEND
it's probably not a big surprise that this went unnoticed for so
long. The Smack rules loading code is incorrectly setting the
MAY_READ bit when MAY_APPEND is requested.

Subject: [PATCH 0522/1079] powerpc/pseries: Correct VIO bus accounting problem
 in CMO env.

In the VIO bus code the wrappers for dma alloc_coherent and free_coherent
calls are rounding to IOMMU_PAGE_SIZE.  Taking a look at the underlying
calls, the actual mapping is promoted to PAGE_SIZE.  Changing the
rounding in these two functions fixes under-reporting the entitlement
used by the system.  Without this change, the system could run out of
entitlement before it believes it has and incur mapping failures at the
firmware level.

Also in the VIO bus code, the wrapper for dma map_sg is not exiting in
an error path where it should.  Rather than fall through to code for the
success case, this patch adds the return that is needed in the error path.

Subject: [PATCH 0523/1079] powerpc/mm: Fix handling of _PAGE_COHERENT in BAT
 setup code

_PAGE_COHERENT is now always set in _PAGE_RAM resp. PAGE_KERNEL.
Thus it has to be masked out, if the BAT mapping should be non
cacheable or CPU_FTR_NEED_COHERENT is not set.

This will work on normal SMP setups because we force-set
CPU_FTR_NEED_COHERENT as part of CPU_FTR_COMMON on SMP.

long time and I do not see why it isn't in mainline.

Subject: [PATCH 0525/1079] IPv6: Fix multicast routing bugs.

This patch addresses the IPv6 multicast routing issues described
below.  It was tested with XORP 1.4/1.5 as the IPv6 PIM-SM routing
daemon against FreeBSD peers.

net/ipv6/ip6_input.c:

  - Don't try to forward link-local multicast packets.

  - Don't reset skb2->dev before calling ip6_mr_input() so packets can
    be identified as coming from the PIM register vif properly.

net/ipv6/ip6mr.c:

  - Fix incoming PIM register messages processing:

    * The IPv6 pseudo-header should be included when checksumming PIM
      messages (RFC 4601 section 4.9; RFC 3973 section 4.7.1).

    * Packets decapsulated from PIM register messages should have
      skb->protocol ETH_P_IPV6.

  - Enable/disable IPv6 multicast forwarding on the corresponding
    interface when a routing daemon adds/removes a multicast virtual
    interface.

  - Remove incorrect skb_pull() to fix userspace signaling.

  - Enable/disable global IPv6 multicast forwarding when an IPv6
    multicast routing socket is opened/closed.

net/ipv6/route.c:

  - Don't use strict routing logic for packets decapsulated from PIM
    register messages (similar to disabling rp_filter for the IPv4
    case).

Subject: [PATCH 0528/1079] slub: fix per cpu kmem_cache_cpu array memory leak

The per cpu array of kmem_cache_cpu structures accomodates
NR_KMEM_CACHE_CPU such structs.

When this array overflows and a struct is allocated by kmalloc(), it may
have an address at the upper bound of this array.  If this happens, it
does not get freed and the per cpu kmem_cache_cpu_free pointer will be out
of bounds after kmem_cache_destroy() or cpu offlining.

Commit d7b1956fed33d30c4815e848fd7a143722916868 ("DMI: Introduce
dmi_first_match to make the interface more flexible") introduced compile
errors like the following when !CONFIG_DMI

    drivers/ata/sata_sil.c: In function 'sil_broken_system_poweroff':
    drivers/ata/sata_sil.c:713: error: implicit declaration of function 'dmi_first_match'
    drivers/ata/sata_sil.c:713: warning: initialization makes pointer from integer without a cast

We just need a dummy version of dmi_first_match() to fix this all up.

Subject: [PATCH 0535/1079] [ARM] 5366/1: fix shared memory coherency with VIVT
 L1 + L2 caches

When there are multiple L1-aliasing userland mappings of the same physical
page, we currently remap each of them uncached, to prevent VIVT cache
aliasing issues. (E.g. writes to one of the mappings not being immediately
visible via another mapping.)  However, when we do this remapping, there
could still be stale data in the L2 cache, and an uncached mapping might
bypass L2 and go straight to RAM.  This would cause reads from such
mappings to see old data (until the dirty L2 line is eventually evicted.)

This issue is solved by forcing a L2 cache flush whenever the shared page
is made L1 uncacheable.

Ideally, we would make L1 uncacheable and L2 cacheable as L2 is PIPT. But
Feroceon does not support that combination, and the TEX=5 C=0 B=0 encoding
for XSc3 doesn't appear to work in practice.

Subject: [PATCH 0537/1079] ACPI: remove locking from PM1x_STS register reads

PM1a_STS and PM1b_STS are twins that get OR'd together
on reads, and all writes are repeated to both.

The fields in PM1x_STS are single bits only,
there are no multi-bit fields.

So it is not necessary to lock PM1x_STS reads against
writes because it is impossible to read an intermediate
value of a single bit.  It will either be 0 or 1,
even if a write is in progress during the read.
Reads are asynchronous to writes no matter if a lock
is used or not.

Subject: [PATCH 0538/1079] ieee1394: support for speeds greater than S800

The hard-wired configuration of the top speed (until now S800) was
unnecessary, remove it.

If the local link layer controller supports S1600 or S3200, we now
assume this speed for all present 1394b PHYs (except if they are
behind 1394a repeaters) until nodemgr figured out the actual speed
while fetching the config ROM.

Subject: [PATCH 0540/1079] ieee1394: sbp2: fix payload limit at S1600 and
 S3200

1394-2008 clause 16.3.4.1 (1394b-2002 clause 16.3.1.1) defines tighter
limits than 1394-2008 clause 6.2.2.3 (1394a-2000 clause 6.2.2.3).

Our previously too large limit doesn't matter though if the controller
reports its max_receive correctly.

Subject: [PATCH 0541/1079] ieee1394: sbp2: don't assume zero model_id or
 firmware_revision if there is none

This makes sbp2 behave more like firewire-sbp2 which reports 0xff000000
as immediate value if there are no unit directory entries for model_id
or firmware_revision.

It does not reduce matches with the currently existing quirks table; the
only zero entry there is for a device which actually does have a zero
model_id.  It only changes how model_id and firmware_revision are logged
if they are missing.

Other functionally unrelated changes:  The model_id member of quirks
list entries is renamed to model;  the value (but not the effect) of
SBP2_ROM_VALUE_WILDCARD is changed.  Now this part of the source is
identical with firewire-sbp2 for easier maintenance.

Subject: [PATCH 0545/1079] Btrfs: fix readdir on 32 bit machines

After btrfs_readdir has gone through all the directory items, it
sets the directory f_pos to the largest possible int.  This way
applications that mix readdir with creating new files don't
end up in an endless loop finding the new directory items as they go.

It was a workaround for a bug in git, but the assumption was that if git
could make this looping mistake than it would be a common problem.

The largest possible int chosen was INT_LIMIT(typeof(file->f_pos),
and it is possible for that to be a larger number than 32 bit glibc
expects to come out of readdir.

This patches switches that to INT_LIMIT(off_t), which should keep
applications happy on 32 and 64 bit machines.

ktime_t isn't ment to directly access on all arches, so use the proper

+The lowmemorykiller driver lets user-space specify a set of memory thresholds
+where processes with a range of oom_adj values will get killed. Specify the
+minimum oom_adj values in /sys/module/lowmemorykiller/parameters/adj and the
+number of free pages in /sys/module/lowmemorykiller/parameters/minfree. Both
+files take a comma separated list of numbers in ascending order.
+
+For example, write "0,8" to /sys/module/lowmemorykiller/parameters/adj and
+"1024,4096" to /sys/module/lowmemorykiller/parameters/minfree to kill processes
+with a oom_adj value of 8 or higher when the free memory drops below 4096 pages
+and kill processes with a oom_adj value of 0 or higher when the free memory
+drops below 1024 pages.
+
+The driver considers memory used for caches to be free, but if a large
+percentage of the cached memory is locked this can be very inaccurate
+and processes may not get killed until the normal oom killer is triggered.

Subject: [PATCH 0557/1079] UIO: Add missing documentation of features added
 recently
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The following features were added to the UIO framework in the near past:

* Generic drivers for platform devices (uio_pdrv, uio_pdrv_genirq)
* an "offset" sysfs attribute for memory mappings

Unfortunately, all this went in without documentation (won't happen again...)

This patch updates UIO documentation.

Subject: [PATCH 0559/1079] ACPI: remove BM_RLD access from idle entry path

It is true that BM_RLD needs to be set to enable
bus master activity to wake an older chipset (eg PIIX4) from C3.

This is contrary to the erroneous wording the ACPI 2.0, 3.0
specifications that suggests that BM_RLD is an indicator
rather than a control bit.

ACPI 1.0's correct wording should be restored in ACPI 4.0:
http://www.acpica.org/bugzilla/show_bug.cgi?id=689

But the kernel should not have to clear BM_RLD
when entering a non C3-type state just to set
it again when entering a C3-type C-state.

We should be able to set BM_RLD at boot time
and leave it alone -- removing the overhead of
accessing this IO register from the idle entry path.

Subject: [PATCH 0566/1079] sh: Handle calling csum_partial with misaligned
 data

In rare circumstances csum_partial() can be called with data which is
not 16 or 32 bit aligned. This is been observed with RPC calls for NFS
file systems for example. Add support for handling this without resorting
to the misaligned fixup code (which is why this hasn't been seen as a
problem). This mimics the i386 version, which has had this support for
some time.

Subject: [PATCH 0569/1079] sh: Fix up spurious syscall restarting.

The T-bit manipulation for syscall error checking had the side effect of
spuriously returning ERESTART* errno values over EINTR. So, we simplify
the error checking a bit and leave the T-bit alone.

Subject: [PATCH 0571/1079] cifs: turn smb_send into a wrapper around smb_sendv

cifs: turn smb_send into a wrapper around smb_sendv

Rename smb_send2 to smb_sendv to make it consistent with kernel naming
conventions for functions that take a vector.

There's no need to have 2 functions to handle sending SMB calls. Turn
smb_send into a wrapper around smb_sendv. This also allows us to
properly mark the socket as needing to be reconnected when there's a
partial send from smb_send.

Also, in practice we always use the address and noblocksnd flag
that's attached to the TCP_Server_Info. There's no need to pass
them in as separate args to smb_sendv.

Subject: [PATCH 0572/1079] [CIFS] Rename md5 functions to avoid collision with
 new rt modules

When rt modules were added they (each) included their own md5
with names which collided with the existing names of cifs's md5 functions.

Renaming cifs's md5 modules so we don't collide with them.

Subject: [PATCH 0573/1079] [CIFS] revalidate parent inode when rmdir done
 within that directory

When a search is pending of a parent directory, and a child directory
within it is removed, we need to reset the parent directory's time
so that we don't reuse the (now stale) search results.

Thanks to Gunter Kukkukk for reporting this:

> got the following failure notification on irc #samba:
>
> A user was updating from subversion 1.4 to 1.5, where the
> repository is located on a samba share (independent of
> unix extensions = Yes or No).
> svn 1.4 did work, 1.5 does not.
>
> The user did a lot of stracing of subversion - and wrote a

Subject: [PATCH 0575/1079] [CIFS] Make socket retry timeouts consistent
 between blocking and nonblocking cases

We have used approximately 15 second timeouts on nonblocking sends in the past, and
also 15 second SMB timeout (waiting for server responses, for most request types).
Now that we can do blocking tcp sends,
make blocking send timeout approximately the same (15 seconds).

Subject: [PATCH 0576/1079] cifs: make sure we allocate enough storage for
 socket address

The sockaddr declared on the stack in cifs_get_tcp_session is too small
for IPv6 addresses. Change it from "struct sockaddr" to "struct
sockaddr_storage" to prevent stack corruption when IPv6 is used.

Subject: [PATCH 0577/1079] HID: adjust report descriptor fixup for MS 1028
 receiver

Report descriptor fixup for MS 1028 receiver changes also values for
Keyboard and Consumer, which incorrectly trims the range, causing correct
events being thrown away before passing to userspace.

We need to keep the GenDesk usage fixup though, as it reports totally bogus
values about axis.

Subject: [PATCH 0581/1079] V4L/DVB (10192): em28xx: fix input selection

em28xx were trying to access the third input entry, even for boards that
don't support it.

This patch reviews the input mux selection fixing this bug and a few
other troubles, like not validating the input on one userspace ioctl.

Subject: [PATCH 0589/1079] V4L/DVB (9054): implement proper locking in the dvb
 ca en50221 driver

Concurrent access to a single DVB CA 50221 interface slot is generally
discouraged. The underlying drivers (budget-av, budget-ci) do not implement
proper locking and thus two transactions could (and do) interfere with on
another.

This fixes the following problems seen by others and myself:

 - sudden i/o errors when writing to the ci device which usually would
   result in an undefined state of the hw and require a software restart

 - errors about the CAM trying to send a buffer larger than the agreed size
   usually also resulting in an undefined state of the hw

Due the to design of the DVB CA 50221 driver, implementing the locks in the
underlying drivers would not be enough and still leave some race conditions,
even though they were harder to trigger.

 by changeset 60b4bde4

Changeset 60b4bde48b36c0315ef41fd38c339b9c7e68c46f removed an unused
struct on zoran driver, when compiled with "Y".

However, as pointed by Jean Delvare <khali@linux-fr.org>, this is
neeeded when the driver is compiled as a module, since udev relies on it
to auto-load the module.

If Hauppauge eeprom is corrupted, the driver returns tuner = 0, instead
of TUNER_ABSENT.

This makes the drivers to initialize tuner, instead of handling the
manual parameter.

Since the tuner core rejects that a tuner to have their type changed,
this breaks the manual tuner override.

Subject: [PATCH 0592/1079] V4L/DVB (10210): Fix a bug on v4lgrab.c

v4lgrab  breaks the fputc macro on some systems, because of #defined
FILE.

Also, I also added comments because it was not at all clear that to get gspca
cameras to work with this application you need v4l1compat.

Subject: [PATCH 0595/1079] V4L/DVB (10216): saa7127: fix broken S-Video with
 saa7129

Register 0x2d has to be set differently in the saa7129 compared to the
saa7127. This was not done correctly, so S-Video was broken in certain
circumstances.

This fixes a regression introduced in 2.6.28.

Subject: [PATCH 0596/1079] V4L/DVB (10218): cx23885: Fix Oops for mixed
 install of analog and digital only cards

Analog support for HVR-1250 has not been completed, but does exist for
the HVR-1800.

Since both cards use the same driver, it tries to create the analog
dev for both devices, which is not possible.

This causes a NULL error to show up in video_open and mpeg_open.

-Mark

Iterations through the cx23885_devlist must check for NULL
pointers as some supported devices only have DVB support at the moment.
Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800
installed.

-Andy

Subject: [PATCH 0597/1079] V4L/DVB (10219): saa7134: Prevent Oops due to stale
 IRQ status when enabling interrupts

When enabling a shared IRQ line, then saa7134_irq handler could be invoked
before the driver had completely set up internal structures, due to a shared
interrupt line firing.  Clear the saa7134 interrupt status reg, before
requesting the irq line, so that stale IRQ status isn't processed before the
internal structures are set up.

Marcin Slusarz recently brought this Oops to the attention of the v4l-dvb
lists and provided an initial analysis by investigating reports found here:

Subject: [PATCH 0598/1079] V4L/DVB (10222): zoran: Better syntax for
 initializing array module params

When initializing a module parameter that is a per-card array, use
"{ [0 ... (BUZ_MAX-1)] = -1 }" instead of "{ -1, -1, -1, -1 }".  This way
all of the entries will be correctly set to -1 if someone changes BUZ_MAX
to a value other than 4.

Adjust some of the parameter help text too.

Subject: [PATCH 0599/1079] V4L/DVB (10223): zoran: Remove global device array

The driver was keeping a global array with an entry for each zoran device
probed.  It was a leftover from when the driver didn't dynamically allocate
the driver data for each device.

There was only one use left, in the video device's ->open() method, looking
up the struct zoran for the opened device from the minor number.  This can
be done better with video_get_drvdata().

Since zoran_num is now only used in the pci driver's ->probe() method, it
doesn't need to be an atomic_t and be static.  There is a race if multiple
zoran cards could be probed at the same time, but currently the probe
method for a given driver is single threaded.

Subject: [PATCH 0600/1079] V4L/DVB (10224): zoran: Use pci device table to get
 card type

Instead of using custom code, just let the device layer look it up for us
from the pci device table.  This requires extending the pci device table to
list each known card, plus a catch-all entry for the cards that don't have
sub-system vendor/device data.

Improve some of the info and error messages too.

Subject: [PATCH 0601/1079] V4L/DVB (10225): zoran: Remove zr36057_adr field

The driver should only use the kernel mapped io address, zr36057_mem, and
not the PCI bus address, zr36057_adr.  Since the latter is only printed out
once, there is no need to save it in the driver data structure.

There was some old code that looked like it was for the Alpha architecture
which would use the PCI bus address.  It probably no longer applies to
modern kernels.

Subject: [PATCH 0602/1079] V4L/DVB (10226): zoran: Get rid of extra module ref
 count

The zoran driver does a module_get/put of THIS_MODULE on device open/close.
This isn't necessary as the kernel does this automatically.

Clean up the failure path of zoran_open() somewhat.

Make the dprintk()s on open/close a higher debug level and make the user
count printed take the current open/close into account.

Subject: [PATCH 0603/1079] V4L/DVB (10228): em28xx: fix audio output PCM IN
 selection

Some em28xx devices use the PCM IN AC 97 PIN for digital audio. However,
currently, the PCM IN selection is not set by the driver. This patch allows
specifying the PCM IN expected output, via board description table.

Subject: [PATCH 0606/1079] V4L/DVB (10233): [PATCH] Terratec Cinergy DT XS
 Diversity new USB ID (0ccd:0081)

The following patch adds support for a new version of the
Terratec Cinergy DT USB XS Diversity Dual DVB-T TV tuner stick.
The USB ID of the new stick is 0ccd:0081.
The hardware of the stick has changed, when compared to the first version of
this stick, but it still uses quite standard components, so that only minor
changes are needed to the sources.

The patch has been successfully tested with hotplugging the device and then
2 x tzap and 2 x mplayer, to watch two different TV programs simultaneously.

The stick works with both, the old and new firmwares:
- dvb-usb-dib0700-1.10.fw and
- dvb-usb-dib0700-1.20.fw

Subject: [PATCH 0610/1079] V4L/DVB (10250): cx25840: fix regression: fw not
 loaded on first use

With the conversion to v4l2_subdev one bit of code was accidentally dropped:
on receiving the first command the driver has to load the fw. A new init()
command was introduced to do that explicitly for bridge drivers that are
converted to use v4l2_subdev, but old drivers that are not yet converted
no longer worked.

This patch fixes this regression for these old drivers.

 shutdown

Revert a change made in change 9743 which resulted in a kernel panic in some
cases on shutdown of the audio stream.

First discovered when working on the Pinnacle 880e support, and later
reproduced by a user on the mailing list with the HVR-900 as well.

Subject: [PATCH 0615/1079] x86: tone down mtrr_trim_uncached_memory() warning

kerneloops.org is reporting a lot of these warnings that come due to
vmware not setting up any MTRRs for emulated CPUs:

| Reported 709 times (14696 total reports)
| BIOS bug (often in VMWare) where the MTRR's are set up incorrectly
| or not at all
|
| This warning was last seen in version 2.6.29-rc2-git1, and first
| seen in 2.6.24.
|
| More info:
|   http://www.kerneloops.org/searchweek.php?search=mtrr_trim_uncached_memory

Keep a one-liner KERN_INFO about it - so that we have so notice if empty
MTRRs are caused by native hardware/BIOS weirdness.

Subject: [PATCH 0616/1079] V4L/DVB (10265): budget.c driver: Kernel oops:
 "BUG: unable to handle kernel paging request at ffffffff

I'm using a "Hauppauge WinTV-NOVA-T DVB card" of PCI id "13c2:1005" with
kernel 2.6.27.9.

I've recently experienced the following fairly consistent kernel oops on
startup in grundig_29504_401_tuner_set_params from budget.c. As you
might expect, following this failure, the card doesn't work.

I'm not a kernel developer, nevertheless I seem to have managed to track
this down to a non-existent initialisation of
budget->dvb_frontend->tuner_priv.

The attached patch fixes the problem for me (and I've managed to tune
the card successfully as a result), but I don't know of anyone else
using the driver so I can't test it on other people.

Please let me know if this works for you or if I've done something
terribly wrong ;-(

These days TUNER_SET_CONFIG is broadcast to the other i2c devices
and that triggers a fw load on the cx25840. Ignore this command
since cx25840 isn't a tuner and you really do not want to load
the firmware that early.

 =======================

The culprit in the trace is snd_pcm_action() which invokes a spin lock
which disables pre-emption which disables an IRQ which causes the
__might_sleep() function to fail the irqs_disabled() test.  Since
pre-emption is enabled then it is safe to de-allocate the memory if
you first unlink each URB.  In this instance you are safe since
pre-emption is disabled.  If pre-emption and irqs are not disabled then
call usb_kill_urb(), else call usb_unlink_urb().

Thanks to Douglas for tracking down this bug originally!!!

1: make "target_kb" only accept and produce a memory size in kilobytes.
2: add a second "target" file which produces output in bytes, and will accept
   memparse input (scaled bytes)

This fixes the rather irritating problem that writing the same value
read back into target_kb would end up shrinking the domain by a factor
of 1024, with generally bad results.

The WM8753 driver multiplexes the DAI structures it exposes to the
outside world, leaving them uninitialised until the codec probes.  Since
the DAI name is used during the registration and setup process provide a
dummy name.

Subject: [PATCH 0627/1079] ASoC: OMAP: Initialize XCCR and RCCR registers in
 McBSP DAI driver

This patch explicitly initializes McBSP Transmit Configuration
Control Register (XCCR) and Receive Configuration Control
Register (RCCR) to their reset values. Reset values are 26 ns
of DX delay and Transmit DMA disabled for XCCR register;
receive full cycle mode enabled and Receive DMA disabled for
RCCR register.

This patch requires a counterpart in OMAP McBSP driver before
to apply it. The required changes in McBSP were sent and approved
in linux-omap mailing list and patch is going upstream
(commit 3127f8f8595a064b3f1a1837fea2177902589ac3 from linux-omap-2.6
tree).

Subject: [PATCH 0631/1079] UBIFS: return sensible error codes

When mounting/re-mounting, UBIFS returns EINVAL even if the ENOSPC
or EROFS codes are are much better, just because we have not found
references to ENOSPC/EROFS in mount (2) man pages. This patch
changes this behaviour and makes UBIFS return real error code,
because:

1. It is just less confusing and more logical
2. mount is not described in SuSv3, so it seems to be not really
   well-standartized
3. we do not cover all cases, and any random undocumented in man
   pages error code may be returned anyway

Subject: [PATCH 0632/1079] UBIFS: remove fast unmounting

This UBIFS feature has never worked properly, and it was a mistake
to add it because we simply have no use-cases. So, lets still accept
the fast_unmount mount option, but ignore it. This does not change
much, because UBIFS commit in sync_fs anyway, and sync_fs is called
while unmounting.

Subject: [PATCH 0633/1079] ARM: OMAP: Fix McBSP spin_lock deadlock

A spin_lock deadlock will occur when omap_mcbsp_request() is invoked.

omap_mcbsp_request()
\- clk_enable(mcbsp->clk)         [takes and holds clockfw_lock]
    \- omap2_clk_enable()
       \- _omap2_clk_enable()
           \- omap_mcbsp_clk_enable()
              \- clk_enable(child clock)   [tries for clockfw_lock again]

mcbsp_clk is a virtual clock and it comprises several child clocks. when
enable mcbsp_clk in omap_mcbsp_request(), the enable function of mcbsp_clk
will enable its child clocks, then the deadlock occurs.

The solution is to remove the virtual clock and enable these child clocks in
omap_mcbsp_request() directly.

Subject: [PATCH 0634/1079] ARM: OMAP: Fix race in OMAP2/3 DMA IRQ handling

CSR must be cleared before invoking the callback.

If the callback function starts a new, fast DMA transfer on the same
channel, the completion status might lost if CSR is cleared after
the callback invocation.

Subject: [PATCH 0638/1079] ARM: OMAP: gptimer min_delta_ns corrected

When 32 kHz timer is used the min_delta_ns should be initialized so
that it reflects the timer programming cost. A write to the timer
device will be usually posted, but it takes roughly 3 cycles before
it is effective. If the timer is reprogrammed before that, the CPU
will stall until the previous write completes. This was pointed out by
Richard Woodruff.

Since the lower bound for min_delta_ns is 1000, the change is visible
only with tick rates less than 3 MHz.

Also note that the old value is incorrect for 32 kHz also due to
a rounding error, and it can cause the timer queue to hang (due to
clockevent code trying to program the timer with zero ticks).

Subject: [PATCH 0639/1079] ARM: OMAP: Mask interrupts when disabling
 interrupts, v2

By Ingo Molnar, interrupts are not masked by default.
(refer to 76d2160147f43f982dfe881404cfde9fd0a9da21)

But if interrupts are not masked, the processor can wake up while in
Suspend-to-RAM state by an external interrupt. For example, if an
OMAP3 board is connected to Host PC by USB and entered to Suspend-to-RAM
state, it wake up automatically by M_IRQ_92. The disable_irq() function
can't disable the interrupt in H/W level, So I modified
arch/arm/mach-omap2/irq.c

In omap24xx_cpu_suspend assembly routine, the r2 register which holds
the address of the SDRC_POWER reg is set to zero before the value is
written back triggering a fault due to writing to address zero.

It's hard to tell where this change was introduced since this file
has been moved and merged.

While this fix prevents a crash, suspend on my n810 is broken with
current kernels.  I never come out of suspend.

Subject: [PATCH 0641/1079] firewire: sbp2: add workarounds for 2nd and 3rd
 generation iPods

According to https://bugs.launchpad.net/bugs/294391
  - 3rd generation iPods need the "fix capacity" workaround after all
    (apparently they crash after the last sector was accessed),
  - 2nd generation iPods need the "128 kB maximum request size"
    workaround.

Alas both iPod generations feature the same model ID in the config ROM,
hence we can only define a shared quirks list entry for them.  Luckily
the fix capacity workaround did not show a negative effect in Jarod's
tests with 2nd gen. iPod.

A side note:  Apple computers in target mode (or at least an x86 Mac
mini) don't have firmware_version and model_id, hence none of the iPod
quirks list entries is active for them.

Subject: [PATCH 0644/1079] rtl8187: Fix error in setting OFDM power settings
 for RTL8187L
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After reports of poor performance, a review of the latest vendor driver
(rtl8187_linux_26.1025.0328.2007) for RTL8187L devices was undertaken.

A difference was found in the code used to index the OFDM power tables. When
the Linux driver was changed, my unit works at a much greater range than
before. I think this fixes Bugzilla #12380 and has been tested by at least
two other users.

Subject: [PATCH 0646/1079] cfg80211: Fix sanity check on 5 GHz when processing
 country IE

This fixes two issues with the sanity check loop when processing
the country IE:

1. Do not use frequency for the current subband channel check,
   this was a big fat typo.
2. Apply the 5 GHz 4-channel steps when considering max channel
   on each subband as was done with a recent patch.

Subject: [PATCH 0649/1079] netxen: revert jumbo ringsize

Reducing jumbo ring size below 1024 reduces throughput for old
firmwares (3.4.216 and older) running on older (NX2031) chip,
so restore it back to 1024.

This was reduced in commit 32ec803348b4d5f1353e1d7feae30880b8b3e342
("netxen: reduce memory footprint").

Raising jumbo ring size from 512 to 1024, adds ~4MB per port, but
there's still big saving because of original patch (~20MB per port).

Subject: [PATCH 0650/1079] net: Fix frag_list handling in skb_seq_read

The frag_list handling was broken in skb_seq_read:

1) We didn't add the stepped offset when looking at the head
are of fragments other than the first.

2) We didn't take the stepped offset away when setting the data
pointer in the head area.

3) The frag index wasn't reset.

This patch fixes both issues.

Subject: [PATCH 0652/1079] powerpc/5200: Bugfix for PCI mapping of memory and
 IMMR

This patch ensures that memory gets properly mapped into the PCI
address space.  Without this patch, the memory window BAR is left
at whatever value happened to be loaded into the BAR when Linux
was booted.  Without this patch, memory could end up getting mapped
at any of the 1G address boundaries instead of at '0' where Linux
expects it.

Similarly, this patch also ensures that the internally memory mapped
registers (IMMR) are mapped to the correct PCI address range.

Without this patch, PCI appears to work correctly until a PCI
device is inserted which DMAs into memory.

Subject: [PATCH 0653/1079] net: Fix OOPS in skb_seq_read().

It oopsd for me in skb_seq_read. addr2line said it was
linux-2.6/net/core/skbuff.c:2228, which is this line:


	while (st->frag_idx < skb_shinfo(st->cur_skb)->nr_frags) {


I added some printks in there and it looks like we hit this:

        } else if (st->root_skb == st->cur_skb &&
                   skb_shinfo(st->root_skb)->frag_list) {
                 st->cur_skb = skb_shinfo(st->root_skb)->frag_list;
                 st->frag_idx = 0;
                 goto next_skb;
        }



Actually I did some testing and added a few printks and found that the
st->cur_skb->data was 0 and hence the ptr used by iscsi_tcp was null.
This caused the kernel panic.

 	if (abs_offset < block_limit) {
-		*data = st->cur_skb->data + abs_offset;
+		*data = st->cur_skb->data + (abs_offset - st->stepped_offset);

I enabled the debug_tcp and with a few printks found that the code did
not go to the next_skb label and could find that the sequence being
followed was this -

It hit this if condition -

        if (st->cur_skb->next) {
                st->cur_skb = st->cur_skb->next;
                st->frag_idx = 0;
                goto next_skb;

And so, now the st pointer is shifted to the next skb whereas actually
it should have hit the second else if first since the data is in the
frag_list.

        else if (st->root_skb == st->cur_skb &&
                 skb_shinfo(st->root_skb)->frag_list) {
                st->cur_skb = skb_shinfo(st->root_skb)->frag_list;
                goto next_skb;
        }

Reversing the two conditions the attached patch fixes the issue for me
on top of Herbert's patches.

Subject: [PATCH 0661/1079] wimax: fix build issue when debugfs is disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As reported by Toralf Förster and Randy Dunlap.

- http://linuxwimax.org/pipermail/wimax/2009-January/000460.html

- http://lkml.org/lkml/2009/1/29/279

The definitions needed for the wimax stack and i2400m driver debug
infrastructure was, by mistake, compiled depending on CONFIG_DEBUG_FS
(by them being placed in the debugfs.c files); thus the build broke in
2.6.29-rc3 when debugging was enabled (CONFIG_WIMAX_DEBUG) and
DEBUG_FS was disabled.

These definitions are always needed if debug is enabled at compile
time (independently of DEBUG_FS being or not enabled), so moving them
to a file that is always compiled fixes the issue.

Subject: [PATCH 0662/1079] ucc_geth: Change uec phy id to the same format as
 gianfar's

The commit b31a1d8b41513b96e9c7ec2f68c5734cef0b26a4 ("gianfar: Convert
gianfar to an of_platform_driver") changes the gianfar's phy id to the
format like "mdio@xxxx:xx", but uec still uses the old format like
"xxxxxxxx:xx".  For the board whose UEC uses gianfar-mdio like
MPC8568MDS, the phy can not be attached because of the incompatible
phy id format. This patch changes uec's phy id to the same format as
gianfar's.

Subject: [PATCH 0663/1079] smsc9420: fix interrupt signalling test failures

smsc9420 performs an interrupt signalling test when the interface is
brought up.  The current code mistakenly sets its test flag to false
AFTER enabling the software interrupt source, making failure quite
likely.

This patch changes the code to set the test flag BEFORE enabling
interrupts. I've also removed an smp_wmb because the following spinlock
provides an implicit memory barrier.

Subject: [PATCH 0665/1079] gianfar: Fix Wake-on-LAN support

commit 0f0ca340e57bd7446855fefd07a64249acf81223 ("phy: power
management support") caused a regression in the gianfar driver.

Now phylib turns off PHY power during suspend, and thus WOL
doesn't work anymore.

This patch workarounds the issue by enabling wakeup in the MDIO
device, i.e. just restores the old behaviour for the gianfar
driver. Note that this way all PHYs on a given MDIO bus won't
be turned off during suspend, which isn't good from the power
saving point of view.

A proper, per netdevice wakeup management support will need
a bit reworked phylib suspend/resume logic.

Subject: [PATCH 0668/1079] Fix OOPS in mmap_region() when merging adjacent
 VM_LOCKED file segments

As of commit ba470de43188cdbff795b5da43a1474523c6c2fb ("map: handle
mlocked pages during map, remap, unmap") we now use the 'vma' variable
at the end of mmap_region() to handle the page-in of newly mapped
mlocked pages.

However, if we merged adjacent vma's together, the vma we're using may
be stale.  We historically consciously avoided using it after the merge
operation, but that got overlooked when redoing the locked page
handling.

This commit simplifies mmap_region() by doing any vma merges early,
avoiding the issue entirely, and 'vma' will always be valid.  As pointed
out by Hugh Dickins, this depends on any drivers that change the page
offset of flags to have set one of the VM_SPECIAL bits (so that they
cannot trigger the early merge logic), but that's true in general.

Subject: [PATCH 0675/1079] memcg: get/put parents at create/free

The lifetime of struct cgroup and struct mem_cgroup is different and
mem_cgroup has its own reference count for handling references from
swap_cgroup.

This causes strange problem that the parent mem_cgroup dies while child
mem_cgroup alive, and this problem causes a bug in case of
use_hierarchy==1 because res_counter_uncharge climbs up the tree.

This patch is for avoiding it by getting the parent at create, and putting
it at freeing.

Now, at swapoff, even while try_charge() fails, commit is executed.  This
is a bug which turns the refcnt of cgroup_subsys_state negative.

  and undefined virt_to_phys();

- SMP: arch/alpha/kernel/smp.c:124: warning: passing argument 2
       of '__cpu_test_and_set' discards qualifiers from pointer target type
  Interestingly, this only happens with gcc-4.2; gcc <= 4.1 and gcc-4.3
  are OK. Fixed with extra assignment.

Subject: [PATCH 0684/1079] alpha: fix the BUG() macro

The commit "alpha: teach the compiler that BUG doesn't return"
(ed6b9b97f42c091630335bfb71a2931e6f86388b) moved the asm code into inline
function which takes __FILE__ and __LINE__ as arguments.  This violates
asm constrains there ("i" - an immediate operand with constant value), so
that compile may result in warning or error, depending on compiler
version.

Just adding an infinite loop to the BUG() is sufficient.

Subject: [PATCH 0685/1079] cgroups: fix lock inconsistency in cgroup_clone()

I fixed a bug in cgroup_clone() in Linus' tree in commit 7b574b7
("cgroups: fix a race between cgroup_clone and umount") without noticing
there was a cleanup patch in -mm tree that should be rebased (now commit
104cbd5, "cgroups: use task_lock() for access tsk->cgroups safe in
cgroup_clone()"), thus resulted in lock inconsistency.

Subject: [PATCH 0687/1079] cgroup: fix root_count when mount fails due to busy
 subsystem

root_count was being incremented in cgroup_get_sb() after all error
checking was complete, but decremented in cgroup_kill_sb(), which can be
called on a superblock that we gave up on due to an error.  This patch
changes cgroup_kill_sb() to only decrement root_count if the root was
previously linked into the list of roots.

Subject: [PATCH 0691/1079] epoll: drop max_user_instances and rely only on
 max_user_watches

Linus suggested to put limits where the money is, and max_user_watches
already does that w/out the need of max_user_instances.  That has the
advantage to mitigate the potential DoS while allowing pretty generous
default behavior.

Allowing top 4% of low memory (per user) to be allocated in epoll watches,
we have:

LOMEM    MAX_WATCHES (per user)
512MB    ~178000
1GB      ~356000
2GB      ~712000

A box with 512MB of lomem, will meet some challenge in hitting 180K
watches, socket buffers math teaches us.  No more max_user_instances
limits then.

Subject: [PATCH 0694/1079] Documentation: update CodingStyle tips for Emacs
 users

With the previous Emacs tips example the kernel style was made available
for files in the kernel-tree only. This patch updates the tip to add a
separate cc-mode indent style ("linux-tabs-only"). This makes it easy to
switch between different indent styles and also makes the kernel style
easily available for any filetype mode (c++, awk, ...) that is managed
by the Emacs cc-mode.

Subject: [PATCH 0698/1079] ext4: Remove bogus BUG() check in ext4_bmap()

The code to support journal-less ext4 operation added a BUG to
ext4_bmap() which fired if there was no journal and the
EXT4_STATE_JDATA bit was set in the i_state field.  This caused
running the filefrag program (which uses the FIMBAP ioctl) to trigger
a BUG().

The EXT4_STATE_JDATA bit is only used for ext4_bmap(), and it's
harmless for the bit to be set.  We could add a check in
__ext4_journalled_writepage() and ext4_journalled_write_end() to only
set the EXT4_STATE_JDATA bit if the journal is present, but that adds
an extra test and jump instruction.  It's easier to simply remove the
BUG check.

From 7b24fc4d7eb611da367dea3aad45473050aacd6c Mon Sep 17 00:00:00 2001
From: "Martin K. Petersen" <martin.petersen@oracle.com>
Date: Sun, 4 Jan 2009 02:43:38 -0500
Subject: [PATCH 0700/1079] block: Don't verify integrity metadata on read
 error

If we get an I/O error on a read request there is no point in doing a
verify pass on the integrity buffer.  Adjust the completion path
accordingly.

Subject: [PATCH 0705/1079] block: export SSD/non-rotational queue flag through
 sysfs

For some devices (i.e. CFA ATA) we can't reliably detect whether
the device is of rotational or non-rotational type so we need to
leave the final decision about this setting to the user-space.

As a bonus do a minor CodingStyle fixup in queue_nomerges_store().

Subject: [PATCH 0707/1079] block: add bio_rw_flagged() for testing bio->bi_rw

The existing functions for checking bio->bi_rw are badly named. So lets
mirror what we do for bio->bi_flags testing, use a properly named
function so that it's immediately obvious what is being tested.

Maintain compatability names for the old macros, eventually we'll get
rid of these.

Subject: [PATCH 0709/1079] block: silently error an unsupported barrier bio

This fixes a "regression" from 2.6.28, where the barrier probes that file
systems may do would trigger additional end request warnings in dmesg.

Subject: [PATCH 0710/1079] include/linux: Add bsg.h to the Kernel exported
 headers

bsg.h in current form is perfectly suitable for user-mode
consumption. It is needed together with scsi/sg.h for applications
that want to interface with the bsg driver.

Currently the few projects that use it would copy it over into
the projects. But that is not acceptable for projects that need
to provide source and devel packages for distros.

This should also be submitted to stable 2.6.28 and 2.6.27 since bsg had
a stable API since these Kernels and distro users will need the header
for these kernels a swell

Subject: [PATCH 0713/1079] cfq-iosched: Allow RT requests to pre-empt ongoing
 BE timeslice

This patch adds the ability to pre-empt an ongoing BE timeslice when a RT
request is waiting for the current timeslice to complete. This reduces the
wait time to disk for RT requests from an upper bound of 4 (current value
of cfq_quantum) to 1 disk request.

Applied Jens' suggeested changes to avoid the rb lookup and use !cfq_class_rt()
and retested.

Latency(secs) for the RT task when doing sequential reads from 10G file.
                       | only RT | RT + BE | RT + BE + this patch

large (1Mb) reads      | 142     | 158     | 146

Subject: [PATCH 0723/1079] cpumask: convert lib/smp_processor_id to new
 cpumask ops

Impact: fix debug_smp_processor_id() for CONFIG_CPUMASK_OFFSTACK=y

The scheduler now uses the new cpumask API, which deals up to
nr_cpumask_bits, whereas the API used NR_CPUS bits.

If CONFIG_CPUMASK_OFFSTACK=y these two are not equal, so the top bits
are undefined.  Leading to bug 12518 "BUG: using smp_processor_id() in
preemptible [00000000] code: dellWirelessCtl/..."

The fix is simple: use the modern API in the check.

+MPC5200 Device Tree Bindings
+----------------------------
+
+(c) 2006-2009 Secret Lab Technologies Ltd
+Grant Likely <grant.likely@secretlab.ca>
+
+Naming conventions
+------------------
+For mpc5200 on-chip devices, the format for each compatible value is
+<chip>-<device>[-<mode>].  The OS should be able to match a device driver
+to the device based solely on the compatible value.  If two drivers
+match on the compatible list; the 'most compatible' driver should be
+selected.
+
+The split between the MPC5200 and the MPC5200B leaves a bit of a
+conundrum.  How should the compatible property be set up to provide
+maximum compatibility information; but still accurately describe the
+chip?  For the MPC5200; the answer is easy.  Most of the SoC devices
+originally appeared on the MPC5200.  Since they didn't exist anywhere
+else; the 5200 compatible properties will contain only one item;
+"fsl,mpc5200-<device>".
+
+The 5200B is almost the same as the 5200, but not quite.  It fixes
+silicon bugs and it adds a small number of enhancements.  Most of the
+devices either provide exactly the same interface as on the 5200.  A few
+devices have extra functions but still have a backwards compatible mode.
+To express this information as completely as possible, 5200B device trees
+should have two items in the compatible list:
+	compatible = "fsl,mpc5200b-<device>","fsl,mpc5200-<device>";
+
+It is *strongly* recommended that 5200B device trees follow this convention
+(instead of only listing the base mpc5200 item).
+
+ie. ethernet on mpc5200: compatible = "fsl,mpc5200-fec";
+    ethernet on mpc5200b: compatible = "fsl,mpc5200b-fec", "fsl,mpc5200-fec";
+
+Modal devices, like PSCs, also append the configured function to the
+end of the compatible field.  ie. A PSC in i2s mode would specify
+"fsl,mpc5200-psc-i2s", not "fsl,mpc5200-i2s".  This convention is chosen to
+avoid naming conflicts with non-psc devices providing the same
+function.  For example, "fsl,mpc5200-spi" and "fsl,mpc5200-psc-spi" describe
+the mpc5200 simple spi device and a PSC spi mode respectively.
+
+At the time of writing, exact chip may be either 'fsl,mpc5200' or
+'fsl,mpc5200b'.
+
+The soc node
+------------
+This node describes the on chip SOC peripherals.  Every mpc5200 based
+board will have this node, and as such there is a common naming
+convention for SOC devices.
+
+Required properties:
+name			description
+----			-----------
+ranges			Memory range of the internal memory mapped registers.
+			Should be <0 [baseaddr] 0xc000>
+reg			Should be <[baseaddr] 0x100>
+compatible		mpc5200: "fsl,mpc5200-immr"
+			mpc5200b: "fsl,mpc5200b-immr"
+system-frequency	'fsystem' frequency in Hz; XLB, IPB, USB and PCI
+			clocks are derived from the fsystem clock.
+bus-frequency		IPB bus frequency in Hz.  Clock rate
+			used by most of the soc devices.
+
+soc child nodes
+---------------
+Any on chip SOC devices available to Linux must appear as soc5200 child nodes.
+
+Note: The tables below show the value for the mpc5200.  A mpc5200b device
+tree should use the "fsl,mpc5200b-<device>","fsl,mpc5200-<device>" form.
+

+
+fsl,mpc5200-gpt nodes
+---------------------
+On the mpc5200 and 5200b, GPT0 has a watchdog timer function.  If the board
+design supports the internal wdt, then the device node for GPT0 should
+include the empty property 'fsl,has-wdt'.
+
+An mpc5200-gpt can be used as a single line GPIO controller.  To do so,
+add the following properties to the gpt node:
+	gpio-controller;
+	#gpio-cells = <2>;
+When referencing the GPIO line from another node, the first cell must always
+be zero and the second cell represents the gpio flags and described in the
+gpio device tree binding.
+
+An mpc5200-gpt can be used as a single line edge sensitive interrupt
+controller.  To do so, add the following properties to the gpt node:
+	interrupt-controller;
+	#interrupt-cells = <1>;
+When referencing the IRQ line from another node, the cell represents the
+sense mode; 1 for edge rising, 2 for edge falling.
+
+fsl,mpc5200-psc nodes
+---------------------
+The PSCs should include a cell-index which is the index of the PSC in
+hardware.  cell-index is used to determine which shared SoC registers to
+use when setting up PSC clocking.  cell-index number starts at '0'.  ie:
+	PSC1 has 'cell-index = <0>'
+	PSC4 has 'cell-index = <3>'
+
+PSC in i2s mode:  The mpc5200 and mpc5200b PSCs are not compatible when in
+i2s mode.  An 'mpc5200b-psc-i2s' node cannot include 'mpc5200-psc-i2s' in the
+compatible field.
+
+
+fsl,mpc5200-gpio and fsl,mpc5200-gpio-wkup nodes
+------------------------------------------------
+Each GPIO controller node should have the empty property gpio-controller and
+#gpio-cells set to 2. First cell is the GPIO number which is interpreted
+according to the bit numbers in the GPIO control registers. The second cell
+is for flags which is currently unused.
+
+fsl,mpc5200-fec nodes
+---------------------
+The FEC node can specify one of the following properties to configure
+the MII link:
+- fsl,7-wire-mode - An empty property that specifies the link uses 7-wire
+                    mode instead of MII
+- current-speed   - Specifies that the MII should be configured for a fixed
+                    speed.  This property should contain two cells.  The
+                    first cell specifies the speed in Mbps and the second
+                    should be '0' for half duplex and '1' for full duplex
+- phy-handle      - Contains a phandle to an Ethernet PHY.
+
+Interrupt controller (fsl,mpc5200-pic) node
+-------------------------------------------
+The mpc5200 pic binding splits hardware IRQ numbers into two levels.  The
+split reflects the layout of the PIC hardware itself, which groups
+interrupts into one of three groups; CRIT, MAIN or PERP.  Also, the
+Bestcomm dma engine has it's own set of interrupt sources which are
+cascaded off of peripheral interrupt 0, which the driver interprets as a
+fourth group, SDMA.
+
+The interrupts property for device nodes using the mpc5200 pic consists
+of three cells; <L1 L2 level>
+
+    L1 := [CRIT=0, MAIN=1, PERP=2, SDMA=3]
+    L2 := interrupt number; directly mapped from the value in the
+          "ICTL PerStat, MainStat, CritStat Encoded Register"
+    level := [LEVEL_HIGH=0, EDGE_RISING=1, EDGE_FALLING=2, LEVEL_LOW=3]
+
+For external IRQs, use the following interrupt property values (how to
+specify external interrupts is a frequently asked question):
+External interrupts:
+	external irq0:	interrupts = <0 0 n>;
+	external irq1:	interrupts = <1 1 n>;
+	external irq2:	interrupts = <1 2 n>;
+	external irq3:	interrupts = <1 3 n>;
+'n' is sense (0: level high, 1: edge rising, 2: edge falling 3: level low)

-This document specifies the requirements on the device-tree for mpc5200
-based boards.  These requirements are above and beyond the details
-specified in either the Open Firmware spec or booting-without-of.txt
-
-All new mpc5200-based boards are expected to match this document.  In
-cases where this document is not sufficient to support a new board port,
-this document should be updated as part of adding the new board support.
-
-II - Philosophy
-===============
-The core of this document is naming convention.  The whole point of
-defining this convention is to reduce or eliminate the number of
-special cases required to support a 5200 board.  If all 5200 boards
-follow the same convention, then generic 5200 support code will work
-rather than coding special cases for each new board.
-
-This section tries to capture the thought process behind why the naming
-convention is what it is.
-
-1.  names
----------
-There is strong convention/requirements already established for children
-of the root node.  'cpus' describes the processor cores, 'memory'
-describes memory, and 'chosen' provides boot configuration.  Other nodes
-are added to describe devices attached to the processor local bus.
-
-Following convention already established with other system-on-chip
-processors, 5200 device trees should use the name 'soc5200' for the
-parent node of on chip devices, and the root node should be its parent.
-
-Child nodes are typically named after the configured function.  ie.
-the FEC node is named 'ethernet', and a PSC in uart mode is named 'serial'.
-
-2. device_type property
------------------------
-similar to the node name convention above; the device_type reflects the
-configured function of a device.  ie. 'serial' for a uart and 'spi' for
-an spi controller.  However, while node names *should* reflect the
-configured function, device_type *must* match the configured function
-exactly.
-
-3. compatible property
-----------------------
-Since device_type isn't enough to match devices to drivers, there also
-needs to be a naming convention for the compatible property.  Compatible
-is an list of device descriptions sorted from specific to generic.  For
-the mpc5200, the required format for each compatible value is
-<chip>-<device>[-<mode>].  The OS should be able to match a device driver
-to the device based solely on the compatible value.  If two drivers
-match on the compatible list; the 'most compatible' driver should be
-selected.
-
-The split between the MPC5200 and the MPC5200B leaves a bit of a
-conundrum.  How should the compatible property be set up to provide
-maximum compatibility information; but still accurately describe the
-chip?  For the MPC5200; the answer is easy.  Most of the SoC devices
-originally appeared on the MPC5200.  Since they didn't exist anywhere
-else; the 5200 compatible properties will contain only one item;
-"mpc5200-<device>".
-
-The 5200B is almost the same as the 5200, but not quite.  It fixes
-silicon bugs and it adds a small number of enhancements.  Most of the
-devices either provide exactly the same interface as on the 5200.  A few
-devices have extra functions but still have a backwards compatible mode.
-To express this information as completely as possible, 5200B device trees
-should have two items in the compatible list;
-"mpc5200b-<device>\0mpc5200-<device>".  It is *strongly* recommended
-that 5200B device trees follow this convention (instead of only listing
-the base mpc5200 item).
-
-If another chip appear on the market with one of the mpc5200 SoC
-devices, then the compatible list should include mpc5200-<device>.
-
-ie. ethernet on mpc5200: compatible = "mpc5200-ethernet"
-    ethernet on mpc5200b: compatible = "mpc5200b-ethernet\0mpc5200-ethernet"
-
-Modal devices, like PSCs, also append the configured function to the
-end of the compatible field.  ie. A PSC in i2s mode would specify
-"mpc5200-psc-i2s", not "mpc5200-i2s".  This convention is chosen to
-avoid naming conflicts with non-psc devices providing the same
-function.  For example, "mpc5200-spi" and "mpc5200-psc-spi" describe
-the mpc5200 simple spi device and a PSC spi mode respectively.
-
-If the soc device is more generic and present on other SOCs, the
-compatible property can specify the more generic device type also.
-
-ie. mscan: compatible = "mpc5200-mscan\0fsl,mscan";
-
-At the time of writing, exact chip may be either 'mpc5200' or
-'mpc5200b'.
-
-Device drivers should always try to match as generically as possible.
-
-III - Structure
-===============
-The device tree for an mpc5200 board follows the structure defined in
-booting-without-of.txt with the following additional notes:
-
-0) the root node
-----------------
-Typical root description node; see booting-without-of
-
-1) The cpus node
-----------------
-The cpus node follows the basic layout described in booting-without-of.
-The bus-frequency property holds the XLB bus frequency
-The clock-frequency property holds the core frequency
-
-2) The memory node
-------------------
-Typical memory description node; see booting-without-of.
-
-3) The soc5200 node
--------------------
-This node describes the on chip SOC peripherals.  Every mpc5200 based
-board will have this node, and as such there is a common naming
-convention for SOC devices.
-
-Required properties:
-name			type		description
-----			----		-----------
-device_type		string		must be "soc"
-ranges			int		should be <0 baseaddr baseaddr+10000>
-reg			int		must be <baseaddr 10000>
-compatible		string		mpc5200: "mpc5200-soc"
-					mpc5200b: "mpc5200b-soc\0mpc5200-soc"
-system-frequency	int		Fsystem frequency; source of all
-					other clocks.
-bus-frequency		int		IPB bus frequency in HZ.  Clock rate
-					used by most of the soc devices.
-#interrupt-cells	int		must be <3>.
-
-Recommended properties:
-name			type		description
-----			----		-----------
-model			string		Exact model of the chip;
-					ie: model="fsl,mpc5200"
-revision		string		Silicon revision of chip
-					ie: revision="M08A"
-
-The 'model' and 'revision' properties are *strongly* recommended.  Having
-them presence acts as a bit of a safety net for working around as yet
-undiscovered bugs on one version of silicon.  For example, device drivers
-can use the model and revision properties to decide if a bug fix should
-be turned on.
-
-4) soc5200 child nodes
-----------------------
-Any on chip SOC devices available to Linux must appear as soc5200 child nodes.
-
-Note: The tables below show the value for the mpc5200.  A mpc5200b device
-tree should use the "mpc5200b-<device>\0mpc5200-<device> form.
-
-Required soc5200 child nodes:
-name		device_type		compatible	Description
-----		-----------		----------	-----------
-cdm@<addr>	cdm			mpc5200-cmd	Clock Distribution
-pic@<addr>	interrupt-controller	mpc5200-pic	need an interrupt
-							controller to boot
-bestcomm@<addr>	dma-controller		mpc5200-bestcomm 5200 pic also requires
-							 the bestcomm device
-
-Recommended soc5200 child nodes; populate as needed for your board
-name		device_type	compatible	  Description
-----		-----------	----------	  -----------
-gpt@<addr>	gpt		fsl,mpc5200-gpt	  General purpose timers
-gpt@<addr>	gpt		fsl,mpc5200-gpt-gpio	General purpose
-							timers in GPIO mode
-gpio@<addr>			fsl,mpc5200-gpio	MPC5200 simple gpio
-							controller
-gpio@<addr>			fsl,mpc5200-gpio-wkup	MPC5200 wakeup gpio
-							controller
-rtc@<addr>	rtc		mpc5200-rtc	  Real time clock
-mscan@<addr>	mscan		mpc5200-mscan	  CAN bus controller
-pci@<addr>	pci		mpc5200-pci	  PCI bridge
-serial@<addr>	serial		mpc5200-psc-uart  PSC in serial mode
-i2s@<addr>	sound		mpc5200-psc-i2s	  PSC in i2s mode
-ac97@<addr>	sound		mpc5200-psc-ac97  PSC in ac97 mode
-spi@<addr>	spi		mpc5200-psc-spi	  PSC in spi mode
-irda@<addr>	irda		mpc5200-psc-irda  PSC in IrDA mode
-spi@<addr>	spi		mpc5200-spi	  MPC5200 spi device
-ethernet@<addr>	network		mpc5200-fec	  MPC5200 ethernet device
-ata@<addr>	ata		mpc5200-ata	  IDE ATA interface
-i2c@<addr>	i2c		mpc5200-i2c	  I2C controller
-usb@<addr>	usb-ohci-be	mpc5200-ohci,ohci-be	USB controller
-xlb@<addr>	xlb		mpc5200-xlb	  XLB arbitrator
-
-Important child node properties
-name		type		description
-----		----		-----------
-cell-index	int		When multiple devices are present, is the
-				index of the device in the hardware (ie. There
-				are 6 PSC on the 5200 numbered PSC1 to PSC6)
-				    PSC1 has 'cell-index = <0>'
-				    PSC4 has 'cell-index = <3>'
-
-5) General Purpose Timer nodes (child of soc5200 node)
-On the mpc5200 and 5200b, GPT0 has a watchdog timer function.  If the board
-design supports the internal wdt, then the device node for GPT0 should
-include the empty property 'fsl,has-wdt'.
-
-6) PSC nodes (child of soc5200 node)
-PSC nodes can define the optional 'port-number' property to force assignment
-order of serial ports.  For example, PSC5 might be physically connected to
-the port labeled 'COM1' and PSC1 wired to 'COM1'.  In this case, PSC5 would
-have a "port-number = <0>" property, and PSC1 would have "port-number = <1>".
-
-PSC in i2s mode:  The mpc5200 and mpc5200b PSCs are not compatible when in
-i2s mode.  An 'mpc5200b-psc-i2s' node cannot include 'mpc5200-psc-i2s' in the
-compatible field.
-
-7) GPIO controller nodes
-Each GPIO controller node should have the empty property gpio-controller and
-#gpio-cells set to 2. First cell is the GPIO number which is interpreted
-according to the bit numbers in the GPIO control registers. The second cell
-is for flags which is currently unsused.
-
-8) FEC nodes
-The FEC node can specify one of the following properties to configure
-the MII link:
-"fsl,7-wire-mode" - An empty property that specifies the link uses 7-wire
-                    mode instead of MII
-"current-speed"   - Specifies that the MII should be configured for a fixed
-                    speed.  This property should contain two cells.  The
-                    first cell specifies the speed in Mbps and the second
-                    should be '0' for half duplex and '1' for full duplex
-"phy-handle"      - Contains a phandle to an Ethernet PHY.
-
-IV - Extra Notes
-================
-
-1. Interrupt mapping
---------------------
-The mpc5200 pic driver splits hardware IRQ numbers into two levels.  The
-split reflects the layout of the PIC hardware itself, which groups
-interrupts into one of three groups; CRIT, MAIN or PERP.  Also, the
-Bestcomm dma engine has it's own set of interrupt sources which are
-cascaded off of peripheral interrupt 0, which the driver interprets as a
-fourth group, SDMA.
-
-The interrupts property for device nodes using the mpc5200 pic consists
-of three cells; <L1 L2 level>
-
-    L1 := [CRIT=0, MAIN=1, PERP=2, SDMA=3]
-    L2 := interrupt number; directly mapped from the value in the
-          "ICTL PerStat, MainStat, CritStat Encoded Register"
-    level := [LEVEL_HIGH=0, EDGE_RISING=1, EDGE_FALLING=2, LEVEL_LOW=3]
-
-2. Shared registers
--------------------
-Some SoC devices share registers between them.  ie. the i2c devices use
-a single clock control register, and almost all device are affected by
-the port_config register.  Devices which need to manipulate shared regs
-should look to the parent SoC node.  The soc node is responsible
-for arbitrating all shared register access.

Subject: [PATCH 0727/1079] generic-ipi: use per cpu data for single cpu ipi
 calls

The smp_call_function can be passed a wait parameter telling it to
wait for all the functions running on other CPUs to complete before
returning, or to return without waiting. Unfortunately, this is
currently just a suggestion and not manditory. That is, the
smp_call_function can decide not to return and wait instead.

The reason for this is because it uses kmalloc to allocate storage
to send to the called CPU and that CPU will free it when it is done.
But if we fail to allocate the storage, the stack is used instead.
This means we must wait for the called CPU to finish before
continuing.

Unfortunatly, some callers do no abide by this hint and act as if
the non-wait option is mandatory. The MTRR code for instance will
deadlock if the smp_call_function is set to wait. This is because
the smp_call_function will wait for the other CPUs to finish their
called functions, but those functions are waiting on the caller to
continue.

This patch changes the generic smp_call_function code to use per cpu
variables if the allocation of the data fails for a single CPU call. The
smp_call_function_many will fall back to the smp_call_function_single
if it fails its alloc. The smp_call_function_single is modified
to not force the wait state.

Since we now are using a single data per cpu we must synchronize the
callers to prevent a second caller modifying the data before the
first called IPI functions complete. To do so, I added a flag to
the call_single_data called CSD_FLAG_LOCK. When the single CPU is
called (which can be called when a many call fails an alloc), we
set the LOCK bit on this per cpu data. When the caller finishes
it clears the LOCK bit.

The caller must wait till the LOCK bit is cleared before setting
it. When it is cleared, there is no IPI function using it.

Subject: [PATCH 0809/1079] Allow opportunistic merging of VM_CAN_NONLINEAR
 areas

Commit de33c8db5910cda599899dd431cc30d7c1018cbf ("Fix OOPS in
mmap_region() when merging adjacent VM_LOCKED file segments") unified
the vma merging of anonymous and file maps to just one place, which
simplified the code and fixed a use-after-free bug that could cause an
oops.

But by doing the merge opportunistically before even having called
->mmap() on the file method, it now compares two different 'vm_flags'
values: the pre-mmap() value of the new not-yet-formed vma, and previous
mappings of the same file around it.

And in doing so, it refused to merge the common file case, which adds a
marker to say "I can be made non-linear".

This fixes it by just adding a set of flags that don't have to match,
because we know they are ok to merge.  Currently it's only that single
VM_CAN_NONLINEAR flag, but at least conceptually there could be others
in the future.

And while at it, convert all functions from macros to inline functions
for sanity.

Subject: [PATCH 0816/1079] MIPS: IP27: Switch from DMA_IP27 to DMA_COHERENT

The special IP27 DMA code selected by DMA_IP27 has been removed a while
ago turning DMA_IP27 into almost a nop.  Also fixup the broken logic of
its last users memcpy.S and memcpy-inatomic.s.

If a context switch occurred between the watch exception and reading the
watch registers, it would be possible for the new process to corrupt their

this race.

The algorithm works unconditionally. If bitval is one, the first line is
a no op and the second line sets the bit at offset position. Vice versa,
if bitval is zero, the first line clears the bit at offset position and
the second line is a no op.

Subject: [PATCH 0824/1079] MIPS: RB532: Add set_type() function to IRQ struct.

Interrupt Group 4 mapps the GPIO pins enabled as interrupt sources;
add defines to make this clear when addressing them later in code.

The mapped GPIOs support triggering on either level high or low. To
achieve this, the set_type() function calls rb532_gpio_set_ilevel() for
interrupts of the above mentioned group.

As there is no way to alter the triggering characteristics of the other
interrupts, accept level triggering on status high only. (This is just a
guess; but as the system boots fine and interrupt-driven devices (e.g.
serial console) work with no implications, it seems to be right.)

To clear a GPIO mapped IRQ, the source has to be cleared (i.e., the
interrupt status bit of the corresponding GPIO pin). This is done inside
rb532_disable_irq().

After applying these changes I could undo most of my former "fixes" to
pata-rb532-cf. Particularly all interrupt handling can be done
generically via set_irq_type() as it was before.

Subject: [PATCH 0825/1079] MIPS: RB532: Auto disable GPIO alternate function

When a driver calls gpio_set_direction_{input,output}(), it obviously
doesn't want the alternate function for that pin to be active (as the
direction would not matter in that case). This patch ensures alternate
function is disabled when the direction is being changed.

Subject: [PATCH 0826/1079] MIPS: RB532: remove useless CF GPIO initialisation

As the pata-rb532-cf driver calls gpio_direction_input(), the calls to
rb532_gpio_set_func() and rb532_gpio_direction_input() are not needed since
the alternate function is automatically being disabled when changing the
GPIO pin direction.
The later two calls to rb532_gpio_set_{ilevel,istat}() are implicitly being
done by the IRQ initialisation of pata-rb532-cf.

These kernel symbols are unused. Also, since dev3 init has been moved to
devices.c, set_434_reg() breaks compiling as it uses dev3.

Subject: [PATCH 0833/1079] MIPS: RB532: Simplify dev3 init

As rb532_dev3_ctl_res is not used by any platform device, it can be dropped
when not used for holding the physical address of the device 3 controller.

Also a size of one byte should suffice when ioremapping the physical
address mentioned above, as only a single byte is being read from and
written to it.

Subject: [PATCH 0837/1079] hrtimers: increase clock min delta threshold while
 interrupt hanging

Impact: avoid timer IRQ hanging slow systems

While using the function graph tracer on a virtualized system, the
hrtimer_interrupt can hang the system on an infinite loop.

This can be caused in several situations:

 - the hardware is very slow and HZ is set too high

 - something intrusive is slowing the system down (tracing under emulation)

... and the next clock events to program are always before the current time.

This patch implements a reasonable compromise: if such a situation is
detected, we share the CPUs time in 1/4 to process the hrtimer interrupts.
This is enough to let the system running without serious starvation.

It has been successfully tested under VirtualBox with 1000 HZ and 100 HZ
with function graph tracer launched. On both cases, the clock events were
increased until about 25 ms periodic ticks, which means 40 HZ.

So we change a hard to debug hang into a warning message and a system that
still manages to limp along.

Subject: [PATCH 0838/1079] hrtimers: allow the hot-unplugging of all cpus

Impact: fix CPU hotplug hang on Power6 testbox

On architectures that support offlining all cpus (at least powerpc/pseries),
hot-unpluging the tick_do_timer_cpu can result in a system hang.

This comes from the fact that if the cpu going down happens to be the
cpu doing the tick, then as the tick_do_timer_cpu handover happens after the
cpu is dead (via the CPU_DEAD notification), we're left without ticks,
jiffies are frozen and any task relying on timers (msleep, ...) is stuck.
That's particularly the case for the cpu looping in __cpu_die() waiting
for the dying cpu to be dead.

This patch addresses this by having the tick_do_timer_cpu handover happen
earlier during the CPU_DYING notification. For this, a new clockevent
notification type is introduced (CLOCK_EVT_NOTIFY_CPU_DYING) which is triggered
in hrtimer_cpu_notify().

Subject: [PATCH 0839/1079] hrtimer: prevent negative expiry value after
 clock_was_set()

Impact: prevent false positive WARN_ON() in clockevents_program_event()

clock_was_set() changes the base->offset of CLOCK_REALTIME and
enforces the reprogramming of the clockevent device to expire timers
which are based on CLOCK_REALTIME. If the clock change is large enough
then the subtraction of the timer expiry value and base->offset can
become negative which triggers the warning in
clockevents_program_event().

Check the subtraction result and set a negative value to 0.

Subject: [PATCH 0844/1079] sfc: SFX7101: Remove workaround for bad link
 training

Early versions of the SFX7101 firmware could complete link training in
a state where it would not adequately cancel noise (Solarflare bug
10750).  We previously worked around this by resetting the PHY after
seeing many Ethernet CRC errors.  This workaround is unsafe since it
takes no account of the interval between errors; it also appears to
be unnecessary with production firmware.  Therefore remove it.

Change sfn4111t_reset() to change only GPIO output enables so that it
doesn't break subsequent I2C operations.

Update comments to explain exactly what we're doing.

Add a short sleep to make sure the FLASH_CFG_1 value is latched before
any subsequent I2C operations.

Subject: [PATCH 0849/1079] sfc: Test for PHYXS faults whenever we cannot test
 link state bits

Depending on the loopback mode, there may be no pertinent link state
bits.  In this case we test the PHYXS RX fault bit instead.  Make
sure to do this in all cases where there are no link state bits.

Subject: [PATCH 0852/1079] sfc: SFX7101/SFT9001: Fix AN advertisements

All 10Xpress PHYs require autonegotiation all the time; enforce this
in the set_settings() method and do not treat it as a workaround.

Remove claimed support for 100M HD mode since it is not supported by
current firmware.

Do not set speed override bits when AN is enabled, and do not use
register 1.49192 for AN configuration as it can override what we set
elsewhere.

Always set the AN selector bits to 1 (802.3).

Fix confusion between Next Page and Extended Next Page.

From 1974cc205e63cec4a17a6b3fca31fa4240ded77e Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Thu, 29 Jan 2009 18:00:07 +0000
Subject: [PATCH 0853/1079] sfc: Replace stats_enabled flag with a disable
 count

Currently we use a spin-lock to serialise statistics fetches and also
to inhibit them for short periods of time, plus a flag to
enable/disable statistics fetches for longer periods of time, during
online reset.  This was apparently insufficient to deal with the several
reasons for stats being disabled.

Subject: [PATCH 0854/1079] packet: Avoid lock_sock in mmap handler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As the mmap handler gets called under mmap_sem, and we may grab
mmap_sem elsewhere under the socket lock to access user data, we
should avoid grabbing the socket lock in the mmap handler.

Since the only thing we care about in the mmap handler is for
pg_vec* to be invariant, i.e., to exclude packet_set_ring, we
can achieve this by simply using a new mutex.

Subject: [PATCH 0862/1079] igb: prevent skb_over panic w/ mtu smaller than 1K

A panic has been observed with frame sizes smaller than 1K.  This has been
root caused to the hardware spanning larger frames across multiple buffers
and then reporting the original frame size in the first descriptor.  To
prevent this we can enable set the LPE bit which in turn will restrict
packet sizes to those set in the RLPML register.

Subject: [PATCH 0866/1079] x86/Voyager: make it build and boot

[
  mingo@elte.hu: these fixes are a subset of changes cherry-picked from:

     git://git.kernel.org:/pub/scm/linux/kernel/git/jejb/voyager-2.6.git

  They fix various problems that recent x86 changes caused in the Voyager
  subarchitecture: both APIC changes and cpumask changes and certain
  cleanups caused subarch assumptions to break.

  Most of these changes are obsolete as the subarch code has been removed
  from the x86 development tree - but we merge them upstream to make Voyager
  build and boot.

Subject: [PATCH 0867/1079] Stop playing silly games with the VM_ACCOUNT flag

The mmap_region() code would temporarily set the VM_ACCOUNT flag for
anonymous shared mappings just to inform shmem_zero_setup() that it
should enable accounting for the resulting shm object.  It would then
clear the flag after calling ->mmap (for the /dev/zero case) or doing
shmem_zero_setup() (for the MAP_ANON case).

This just resulted in vma merge issues, but also made for just
unnecessary confusion.  Use the already-existing VM_NORESERVE flag for
this instead, and let shmem_{zero|file}_setup() just figure it out from
that.

This also happens to make it obvious that the new DRI2 GEM layer uses a
non-reserving backing store for its object allocation - which is quite
possibly not intentional.  But since I didn't want to change semantics
in this patch, I left it alone, and just updated the caller to use the
new flag semantics.

Subject: [PATCH 0868/1079] Fix memory corruption in console selection

Fix an off-by-two memory error in console selection.

The loop below goes from sel_start to sel_end (inclusive), so it writes
one more character.  This one more character was added to the allocated
size (+1), but it was not multiplied by an UTF-8 multiplier.

This patch fixes a memory corruption when UTF-8 console is used and the
user selects a few characters, all of them 3-byte in UTF-8 (for example
a frame line).

When memory redzones are enabled, a redzone corruption is reported.
When they are not enabled, trashing of random memory occurs.

Subject: [PATCH 0869/1079] sched: fix sync wakeups

Pawel Dziekonski reported that the openssl benchmark and his
quantum chemistry application both show slowdowns due to the
scheduler under-parallelizing execution.

The reason are pipe wakeups still doing 'sync' wakeups which
overrides the normal buddy wakeup logic - even if waker and
wakee are loosely coupled.

Fix an inversion of logic in the buddy wakeup code.

 - when we select a buddy to run

Similar to the previous patch, by not clearing buddies we can select entities
past their run quota, which can increase latency. This means we have to clear
group buddies as well.

Do not use the group clear for pick_next_task(), otherwise that'll get O(n^2).

Subject: [PATCH 0878/1079] V4L/DVB (10403): saa7134-alsa: saa7130 doesn't
 support digital audio

According with saa7130 public datasheet, saa7130 doesn't support
digital audio. This is also confirmed by experimental tests. So, it
doesn't make sense to let saa7134-alsa register for those chipsets.

Subject: [PATCH 0879/1079] V4L/DVB (10411): s5h1409: Perform s5h1409 soft
 reset after tuning

Just like with the s5h1411, the s5h1409 needs a soft-reset in order for it
to know that the tuner has been told to change frequencies.  This change
changes the behavior from "random tuning times between 500ms to complete
tuning lock failures" to "tuning lock consistently within 700ms".

Thanks to Robert Krakora <rob.krakora@messagenetsystems.com> for doing
initial testing of the patch on the KWorld 330U.

Subject: [PATCH 0880/1079] Manually revert "mlock: downgrade mmap sem while
 populating mlocked regions"

This essentially reverts commit 8edb08caf68184fb170f4f69c7445929e199eaea.

It downgraded our mmap semaphore to a read-lock while mlocking pages, in
order to allow other threads (and external accesses like "ps" et al) to
walk the vma lists and take page faults etc.  Which is a nice idea, but
the implementation does not work.

Because we cannot upgrade the lock back to a write lock without
releasing the mmap semaphore, the code had to release the lock entirely
and then re-take it as a writelock.  However, that meant that the caller
possibly lost the vma chain that it was following, since now another
thread could come in and mmap/munmap the range.

The code tried to work around that by just looking up the vma again and
erroring out if that happened, but quite frankly, that was just a buggy
hack that doesn't actually protect against anything (the other thread
could just have replaced the vma with another one instead of totally
unmapping it).

The only way to downgrade to a read map _reliably_ is to do it at the
end, which is likely the right thing to do: do all the 'vma' operations
with the write-lock held, then downgrade to a read after completing them
all, and then do the "populate the newly mlocked regions" while holding
just the read lock.  And then just drop the read-lock and return to user
space.

The (perhaps somewhat simpler) alternative is to just make all the
callers of mlock_vma_pages_range() know that the mmap lock got dropped,
and just re-grab the mmap semaphore if it needs to mlock more than one
vma region.

So we can do this "downgrade mmap sem while populating mlocked regions"
thing right, but the way it was done here was absolutely not correct.
Thus the revert, in the expectation that we will do it all correctly
some day.

 pr_debug()

Recently, a patch left DEBUG enabled in the powerpc common PCI code,
resulting in an old bug in a pr_debug() statement to show up and cause
a NULL dereference on some machines.

This fixes the pr_debug() statement and reverts to DEBUG not being
force-enabled in that file.

Subject: [PATCH 0883/1079] fbdev/atyfb: Fix DSP config on some PowerMacs &
 PowerBooks

Since the complete re-write in 2.6.10, some PowerMacs (At least PowerMac 5500
and PowerMac G3 Beige rev A) with ATI Mach64 chip have suffered from unstable
columns in their framebuffer image. This seems to depend on a value (4) read
from PLL_EXT_CNTL register, which leads to incorrect DSP config parameters to
be written to the chip. This patch uses a value calculated by aty_init_pll_ct
instead, as a starting point.

There are questions as to whether this should be extended to other platforms
or maybe made dependent on specific chip types, but in the meantime, this has
been tested on various powermacs and works for them so let's commit it.

 __always_inline

bvec_kmap_irq() and bvec_kunmap_irq() comments say they MUST be inlined,

+Queue sysfs files
+=================
+
+This text file will detail the queue files that are located in the sysfs tree
+for each block device. Note that stacked devices typically do not export
+any settings, since their queue merely functions are a remapping target.
+These files are the ones found in the /sys/block/xxx/queue/ directory.
+
+Files denoted with a RO postfix are readonly and the RW postfix means
+read-write.
+
+hw_sector_size (RO)
+-------------------
+This is the hardware sector size of the device, in bytes.
+
+max_hw_sectors_kb (RO)
+----------------------
+This is the maximum number of kilobytes supported in a single data transfer.
+
+max_sectors_kb (RW)
+-------------------
+This is the maximum number of kilobytes that the block layer will allow
+for a filesystem request. Must be smaller than or equal to the maximum
+size allowed by the hardware.
+
+nomerges (RW)
+-------------
+This enables the user to disable the lookup logic involved with IO merging
+requests in the block layer. Merging may still occur through a direct
+1-hit cache, since that comes for (almost) free. The IO scheduler will not
+waste cycles doing tree/hash lookups for merges if nomerges is 1. Defaults
+to 0, enabling all merges.
+
+nr_requests (RW)
+----------------
+This controls how many requests may be allocated in the block layer for
+read or write requests. Note that the total allocated number may be twice
+this amount, since it applies only to reads or writes (not the accumulated
+sum).
+
+read_ahead_kb (RW)
+------------------
+Maximum number of kilobytes to read-ahead for filesystems on this block
+device.
+
+rq_affinity (RW)
+----------------
+If this option is enabled, the block layer will migrate request completions
+to the CPU that originally submitted the request. For some workloads
+this provides a significant reduction in CPU cycles due to caching effects.
+
+scheduler (RW)
+--------------
+When read, this file will display the current and available IO schedulers
+for this block device. The currently active IO scheduler will be enclosed
+in [] brackets. Writing an IO scheduler name to this file will switch
+control of this block device to that new IO scheduler. Note that writing
+an IO scheduler name to this file will attempt to load that IO scheduler
+module, if it isn't already present in the system.

Subject: [PATCH 0896/1079] ide: add CS5536 host driver (v3)

This is a port of libata's pata_cs5536.c (written by Martin K. Petersen)
to IDE subsystem.

Changes done while at it:

* Reprogram PIO/MWDMA timings if needed before and after DMA transfer
  (chipset uses shared PIO/MWDMA timings).

* Fix cable detection to report 80-wires cable if BIOS set it for any
  device on a port (IDE core will do drive-side cable detection later).

* Don't disable UDMA while programming PIO timings.

* Simplify PCI/MSR support.

Pros of having IDE host driver in addition to libata's one:

* IDE is much lighter than SCSI+libata, the host driver itself is also
  a bit smaller:

   text    data     bss     dec     hex filename
   1261     496       4    1761     6e1 drivers/ata/pata_cs5536.o
   1242     128       4    1374     55e drivers/ide/cs5536.o

* This allows use of IDE features which are unavailable under libata.

v2:
* Fixes per review from Sergei:
  - simplify dependency check in Kconfig
  - use IDE_DRV_MASK also for ->drive_data
  - disable UDMA when programming MWDMA
  - program new DTC timings only when necessary
  - fix printk() level in cs5536_init_one()

* Fix patch description according to comments from Alan and Sergei.

v3:
* Smarter masking of UDMA bits per Sergei's suggestion.

Subject: [PATCH 0897/1079] tx4939ide: typo fix and minor cleanup

The bcount is greater than 0 and less than or equal to 0x10000.
Thus '(bcount & 0xffff) == 0x0000' can be simplified as 'bcount == 0x10000'.

Subject: [PATCH 0899/1079] mmc: Add a MX2/MX3 specific SDHC driver

This patch adds a MX2/MX3 specific SDHC driver. The hardware is basically
the same as in the MX1, but unlike the MX1 controller the MX2
controller just works as expected. Since the MX1 driver has more
workarounds for bugs than anything else I had no success with supporting
MX1 and MX2 in a sane way in one driver.

Subject: [PATCH 0900/1079] mmci: Add support for ST Micro derivate

This patch adds support for the ST Microelectronics version of
the PL180 PrimeCell. They use designer ID 0x80 and have a few
alterations/bugfixes related to open drain and HW flow control.
They also add some SDIO registers, I am unsure if these are
in ST HW only or if this is things also added in later ARM
revisions, but they are included in the mmci.h file for
completeness.

Subject: [PATCH 0901/1079] ricoh_mmc: Use suspend_late/resume_early

If ricoh_mmc suspends before sdhci_pci, it will pull the card
out from under the controller, which could leave the system in
a very confused state.

Using suspend_late/resume_early ensures that sdhci_pci suspends first
and resumes second.

Subject: [PATCH 0903/1079] pxamci: enable DMA for write ops after CMD/RESP

With the PXA270 MMC hardware, there seems to be an issue of
data corruption on writes where a 4KB data block is offset
by one byte.

If we delay enabling the DMA for writes until after the CMD/RESP
has finished, the problem seems to be fixed.

related to PXA270 Erratum #91

Subject: [PATCH 0904/1079] net: Fix userland breakage wrt. linux/if_tunnel.h

Reported by Andrew Walrond <andrew@walrond.org>

Changeset c19e654ddbe3831252f61e76a74d661e1a755530
("gre: Add netlink interface") added an include
of linux/ip.h to linux/if_tunnel.h

We can't really let that get exposed to userspace
because this conflicts with types defined in netinet/ip.h
which userland is almost certainly going to have included
either explicitly or implicitly.

So guard this include with a __KERNEL__ ifdef.

Subject: [PATCH 0909/1079] ocfs2: Push out dropping of dentry lock to ocfs2_wq

Dropping of last reference to dentry lock is a complicated operation involving
dropping of reference to inode. This can get complicated and quota code in
particular needs to obtain some quota locks which leads to potential deadlock.
Thus we defer dropping of inode reference to ocfs2_wq.

It could happen that some limit has been set via quotactl() and in parallel
->mark_dirty() is called from another thread doing e.g. dquot_alloc_space(). In
such case ocfs2_write_dquot() must not try to sync the dquot because that needs
global quota lock but that ranks above transaction start.

Subject: [PATCH 0911/1079] configfs: Silence lockdep on mkdir(), rmdir() and
 configfs_depend_item()

When attaching default groups (subdirs) of a new group (in mkdir() or
in configfs_register()), configfs recursively takes inode's mutexes
along the path from the parent of the new group to the default
subdirs. This is needed to ensure that the VFS will not race with
operations on these sub-dirs. This is safe for the following reasons:

- the VFS allows one to lock first an inode and second one of its
  children (The lock subclasses for this pattern are respectively
  I_MUTEX_PARENT and I_MUTEX_CHILD);
- from this rule any inode path can be recursively locked in
  descending order as long as it stays under a single mountpoint and
  does not follow symlinks.

Unfortunately lockdep does not know (yet?) how to handle such
recursion.

I've tried to use Peter Zijlstra's lock_set_subclass() helper to
upgrade i_mutexes from I_MUTEX_CHILD to I_MUTEX_PARENT when we know
that we might recursively lock some of their descendant, but this
usage does not seem to fit the purpose of lock_set_subclass() because
it leads to several i_mutex locked with subclass I_MUTEX_PARENT by
the same task.

>From inside configfs it is not possible to serialize those recursive
locking with a top-level one, because mkdir() and rmdir() are already
called with inodes locked by the VFS. So using some
mutex_lock_nest_lock() is not an option.

I am proposing two solutions:
1) one that wraps recursive mutex_lock()s with
   lockdep_off()/lockdep_on().
2) (as suggested earlier by Peter Zijlstra) one that puts the
   i_mutexes recursively locked in different classes based on their
   depth from the top-level config_group created. This
   induces an arbitrary limit (MAX_LOCK_DEPTH - 2 == 46) on the
   nesting of configfs default groups whenever lockdep is activated
   but this limit looks reasonably high. Unfortunately, this alos
   isolates VFS operations on configfs default groups from the others
   and thus lowers the chances to detect locking issues.

This patch implements solution 1).

Solution 2) looks better from lockdep's point of view, but fails with
configfs_depend_item(). This needs to rework the locking
scheme of configfs_depend_item() by removing the variable lock recursion
depth, and I think that it's doable thanks to the configfs_dirent_lock.
For now, let's stick to solution 1).

Subject: [PATCH 0912/1079] ocfs2: Access the xattr bucket only before
 modifying it.

In ocfs2_xattr_value_truncate, we may call b-tree codes which will
extend the journal transaction. It has a potential problem that it
may let the already-accessed-but-not-dirtied buffers gone. So we'd
better access the bucket after we call ocfs2_xattr_value_truncate.
And as for the root buffer for the xattr value, b-tree code will
acess and dirty it, so we don't need to worry about it.

Subject: [PATCH 0913/1079] ocfs2: Wakeup the downconvert thread after a
 successful cancel convert

When two nodes holding PR locks on a resource concurrently attempt to
upconvert the locks to EX, the master sends a BAST to one of the nodes. This
message tells that node to first cancel convert the upconvert request,
followed by downconvert to a NL. Only when this lock is downconverted to NL,
can the master upconvert the first node's lock to EX.

While the fs was doing the cancel convert, it was forgetting to wake up the
dc thread after a successful cancel, leading to a deadlock.

Subject: [PATCH 0914/1079] ocfs2: add quota call to ocfs2_remove_btree_range()

We weren't reclaiming the clusters which get free'd from this function,
so any user punching holes in a file would still have those bytes accounted
against him/her. Add the call to vfs_dq_free_space_nodirty() to fix this.
Interestingly enough, the journal credits calculation already took this into
account.

Subject: [PATCH 0915/1079] modules: Use a better scheme for refcounting

Current refcounting for modules (done if CONFIG_MODULE_UNLOAD=y) is
using a lot of memory.

Each 'struct module' contains an [NR_CPUS] array of full cache lines.

This patch uses existing infrastructure (percpu_modalloc() &
percpu_modfree()) to allocate percpu space for the refcount storage.

Instead of wasting NR_CPUS*128 bytes (on i386), we now use
nr_cpu_ids*sizeof(local_t) bytes.

On a typical distro, where NR_CPUS=8, shiping 2000 modules, we reduce
size of module files by about 2 Mbytes. (1Kb per module)

Instead of having all refcounters in the same memory node - with TLB misses
because of vmalloc() - this new implementation permits to have better
NUMA properties, since each  CPU will use storage on its preferred node,
thanks to percpu storage.

Subject: [PATCH 0916/1079] virtio-pci: do not oops on config change if driver
 not loaded

The host really shouldn't be notifying us of config changes
before the device status is VIRTIO_CONFIG_S_DRIVER or
VIRTIO_CONFIG_S_DRIVER_OK.

However, if we do happen to be interrupted while we're not
attached to a driver, we really shouldn't oops. Prevent
this simply by checking that device->driver is non-NULL
before trying to notify the driver of config changes.

Problem observed by doing a "set_link virtio.0 down" with
QEMU before the net driver had been loaded.

Subject: [PATCH 0917/1079] ACPI: Skip the first two elements in the _BCL
 package

According to the Spec the first two elements in the _BCL package won't be

regarded as the available brightness level. The first is the brightness when
full power is connected to the box(It means that the AC adapter is plugged).
The second is the brightness level when the box is on battery.
    If the first two elements are still used while finding the next brightness
level, it will fall back to the lowest level when keeping on pressing
hotkey. (On some boxes the brightness will be changed twice when hotkey is
pressed once. One is in the ACPI video driver. The other is changed by sys I/F.
In the ACPI video driver the first two elements will be used while changing
the brightness. But the first two elements is skipped while using sys I/F.
In such case there exists the inconsistency).
    So he first two elements had better be skipped while showing the available
brightness or finding the next brightness level.

 flags for async scanning

The SSS flag, which directs the OS to spin up one disk at a time
to not have the PSU blow out, sometimes gets set even when not needed.
The effect of this is a longer-than-needed boot time.

This patch adds a module parameter that makes the driver ignore SSS
at least as far as the parallel scan during boot is concerned...

Subject: [PATCH 0924/1079] sata_nv: ck804 has borked hardreset too

While playing with nvraid, I found out that rmmoding and insmoding
often trigger hardreset failure on the first port (the second one was
always okay).  Seriously, how diverse can you get with hardreset
behaviors?  Anyways, make ck804 use noclassify variant too.

Subject: [PATCH 0925/1079] libata: fix EH device failure handling

The dev->pio_mode > XFER_PIO_0 test is there to avoid unnecessary
speed down warning messages but it accidentally disabled SATA link spd
down during configuration phase after reset where PIO mode is always
zero.

This patch fixes the problem by moving the test where it belongs.
This makes libata probing sequence behave better when the connection
is flaky at higher link speeds which isn't too uncommon for eSATA
devices.

Subject: [PATCH 0928/1079] libata: clear dev->ering in smarter way

dev->ering used to be cleared together with the rest of ata_device in
ata_dev_init() which is called whenever a probing event occurs.
dev->ering is about to be used to track probing failures so it needs
to remain persistent over multiple porbing events.  This patch
achieves this by doing the following.

* Instead of CLEAR_OFFSET, define CLEAR_BEGIN and CLEAR_END and only
  clear between BEGIN and END.  ering is moved after END.  The split
  of persistent area is to allow hotter items remain at the head.

* ering is explicitly cleared on ata_dev_disable() and when device
  attach succeeds.  So, ering is persistent throug a device's life
  time (unless explicitly cleared of course) and also through periods
  inbetween disablement of an attached device and successful detection
  of the next one.

Subject: [PATCH 0930/1079] libata: improve probe failure handling

When link is flaky at high speed, it isn't uncommon for a device to
repeatedly fail probing sequence early after successfully negotiating
high link speed.  This often leads to consecutive hotplug events
without successful probing.

This patch improves libata EH such that it remembers probing trials
and if there have been more than two unsuccessful trials in the past
60 seconds, slows down link speed to 1.5Gbps.

As link speed negotiation is the duty of the PHY layer proper, the
goal of this fallback mechanism is to provide the last resort when
everything else fails, which unfortunately happens not too
infrequently, so no fancy 6->3->1.5 speeding down or highest
successful transmission speed seen kind of logics (yet).

 handling routines

Let -EAGAIN from EH device handling routines trigger EH retry without
consuming its tries count.  This will be used to implement link SPD
horkage which requires hardreset to adjust SPD without affecting other
EH decisions.  As it bypasses the forward progress guarantee provided
by the tries count, the requester is responsible for ensuring forward
progress.

Subject: [PATCH 0932/1079] libata: implement HORKAGE_1_5_GBPS and apply it to
 WD My Book

3Gbps is often much more prone to transmission failures.  It's usually
okay to let EH handle speed down after transmission failures but some
WD My Book drives completely shutdown after certain transmission
failures and after it only power cycling can revive them.  Combined
with the fact that external drives often end up with cable assembly
which is longer than usual and more likely to have intervening gender,
this makes these drives very likely to shutdown under certain
configurations virtually rendering them unusable.

This patch implements HOARKGE_1_5_GBPS and applies it to WD My Book
such that 1.5Gbps is forced once the device is identified.

Please take a look at the following bz for related reports.

 unwinder

Impact: Fixes dumpstack and KDB on 64 bits

This re-adds the old stack pointer to the top of the irqstack to help
with unwinding.  It was removed in commit d99015b1abbad743aa049b439c1e1dede6d0fa49
as part of the save_args out-of-line work.

Both dumpstack and KDB require this information.

Subject: [PATCH 0936/1079] sparc64: On non-Niagara, need to touch NMI watchdog
 in NOHZ mode.

When we're idling in NOHZ mode, timer interrupts are not running.

Evidence of processing timer interrupts is what the NMI watchdog
uses to determine if the CPU is stuck.

On Niagara, we'll yield the cpu.  This will make the cpu, at
worst, hang out in the hypervisor until an interrupt arrives.
This will prevent the NMI watchdog timer from firing.

However on non-Niagara we just loop executing instructions
which will cause the NMI watchdog to keep firing.  It won't
see timer interrupts happening so it will think the cpu is
stuck.

Fix this by touching the NMI watchdog in the cpu idle loop
on non-Niagara machines.

Subject: [PATCH 0939/1079] sparc64: Validate kernel generated fault addresses
 on sparc64.

In order to handle all of the cases of address calculation overflow
properly, we run sparc 32-bit processes in "address masking" mode
when running on a 64-bit kernel.

Address masking mode zeros out the top 32-bits of the address
calculated for every load and store instruction.

However, when we're in privileged mode we have to run with that
address masking mode disabled even when accessing userspace from
the kernel.

To "simulate" the address masking mode we clear the top-bits by
hand for 32-bit processes in the fault handler.

It is the responsibility of code in the compat layer to properly
zero extend addresses used to access userspace.  If this isn't
followed properly we can get into a fault loop.

Say that the user address is 0xf0000000 but for whatever reason
the kernel code sign extends this to 64-bit, and then the kernel
tries to access the result.

In such a case we'll fault on address 0xfffffffff0000000 but the fault
handler will process that fault as if it were to address 0xf0000000.
We'll loop faulting forever because the fault never gets satisfied.

So add a check specifically for this case, when the kernel is faulting
on a user address access and the addresses don't match up.

This code path is sufficiently slow path, and this bug is sufficiently
painful to diagnose, that this kind of bug check is warranted.

If just thereafter test() succeeds and a break occurs, the goto
still occurs because limit is 0.

Subject: [PATCH 0945/1079] ftrace: do_each_pid_task() needs rcu lock

"ftrace: use struct pid" commit 978f3a45d9499c7a447ca7615455cefb63d44165
converted ftrace_pid_trace to "struct pid*".

But we can't use do_each_pid_task() without rcu_read_lock() even if
we know the pid itself can't go away (it was pinned in ftrace_pid_write).
The exiting task can detach itself from this pid at any moment.

Subject: [PATCH 0947/1079] hso: add new device id's

This patch adds a few device ID's. It also removes an ID that was used
in an internal engineering version of a device and will never see
commercial light. Even if this ID will be 'recycled' in the future,
which is very unlikely, we don't know what kind of device will be
behind it. Therefore it's safer to remove it.

Subject: [PATCH 0952/1079] sparc64: Kill bogus TPC/address truncation during
 32-bit faults.

This builds upon eeabac7386ca13bfe1a58afeb04326a9e1a3a20e
("sparc64: Validate kernel generated fault addresses on sparc64.")

Upon further consideration, we actually should never see any
fault addresses for 32-bit tasks with the upper 32-bits set.

If it does every happen, by definition it's a bug.  Whatever
context created that fault would only have that fault satisfied
if we used the full 64-bit address.  If we truncate it, we'll
always fault the wrong address and we'll always loop faulting
forever.

So catch such conditions and mark them as errors always.  Log
the error and fail the fault.

 2. Decrement wbc->nr_to_write _only_ if wbc->sync_mode == WB_SYNC_NONE
 3. If synced nr_to_write pages, stop only if if wbc->sync_mode ==
    WB_SYNC_NONE, otherwise keep going.

However, according to the commit message, the intention was to only make
change 3.  Change 1 is a bug.  Change 2 does not seem to be necessary,
and it breaks UBIFS expectations, so if needed, it should be done
separately later.  And change 2 does not seem to be documented in the
commit message.

This patch does the following:
 1. Undo changes 1 and 2
 2. Add a comment explaining change 3 (it very useful to have comments
    in _code_, not only in the commit).

Subject: [PATCH 0955/1079] xen: disable interrupts before saving in percpu

Impact: Fix race condition

xen_mc_batch has a small preempt race where it takes the address of a
percpu variable immediately before disabling interrupts, thereby
leaving a small window in which we may migrate to another cpu and save
the flags in the wrong percpu variable.  Disable interrupts before
saving the old flags in a percpu.

Impact: fix to enable APIC for AMD Fam10h on chipsets with a missing/b0rked
	ACPI MP table (MADT)

Booting a 32bit kernel on an AMD Fam10h CPU running on chipsets with
missing/b0rked MP table leads to a hang pretty early in the boot process
due to the APIC not being initialized. Fix that by falling back to the
default APIC base address in 32bit code, as it is done in the 64bit
codepath.

Subject: [PATCH 0957/1079] ACPI: make some IO ports off-limits to AML

ACPICA exports acpi_os_validate_address() so the OS
can prevent BIOS AML from accessing specified addresses.

Start using this interface to prevent AML from accessing
some well known IO addresses that the OS "owns".

Subject: [PATCH 0964/1079] Blackfin arch: Fix Bug - Kernel does not boot if
 re-program clocks

On BF561 EBIU_SDGCTL bit 31 controls the SDRAM external data
path width, typically set 0 for a 32-bit bus width. On other
Blackfin derivatives this bit should be set by default.

Subject: [PATCH 0966/1079] Blackfin arch: reset POLAR setting when acquiring a
 gpio for the first time

when requesting a GPIO for the first time, the POLAR setting is not
set to a sane state.  this can lead to indeterminate behavior that
cannot be resolved without an explicit write to the Blackfin port POLAR
register.

when requesting a GPIO for the first time via gpio_request(), the POLAR
setting for the GPIO in question should be set to sane state.  this
should occur if the GPIO has not been allocated in any other way.

some examples:
 - when doing something like "request_irq(); gpio_request();" on the
   same GPIO, the POLAR setting should not be reset.
 - when doing "gpio_request(); gpio_request();" on the same GPIO, the
   POLAR setting should be reset only the first time and not the second.

Subject: [PATCH 0969/1079] Blackfin arch: explicit add a might sleep to
 gpio_free

According to the documentation gpio_free should only be called from task
context only.  To make this more explicit add a might sleep to all
implementations.

This patch changes the gpio_free implementations for the blackfin
architecture.

Subject: [PATCH 0991/1079] Blackfin arch: fix bug - traps test case 19 for
 exception 0x2d fails

Enable null pointer checking for ICPLBs. The code was there but for
some reason I had commented it out at some stage during development.

Should restrict this to 1K since atomic ops start there.

Subject: [PATCH 0992/1079] Blackfin arch: cplb mananger: use a do...while loop
 rather than a for loop

use a do...while loop rather than a for loop to get slightly better
optimization and to avoid gcc "may be used uninitialized" warnings ...
we know that the [id]cplb_nr_bounds variables will never be 0, so this
is OK

Subject: [PATCH 0998/1079] Blackfin arch: Remove outdated code

The removed version with the loop registers saved on the stack was
originally intended to workaround the missing toolchain support for
LoopReg Clobbers.

Since our toolchain now supports these there is no point in keeping this
workaround. And since we don't touch LoopRegs anymore we're no longer
subject for ANOMALY_05000312.

Subject: [PATCH 1002/1079] Btrfs: async threads should try harder to find work

Tracing shows the delay between when an async thread goes to sleep
and when more work is added is often very short.  This commit adds
a little bit of delay and extra checking to the code right before
we schedule out.

It allows more work to be added to the worker
without requiring notifications from other procs.

Subject: [PATCH 1003/1079] Btrfs: sort references by byte number during
 btrfs_inc_ref

When a block goes through cow, we update the reference counts of
everything that block points to.  The internal pointers of the block
can be in just about any order, and it is likely to have clusters of
things that are close together and clusters of things that are not.

To help reduce the seeks that come with updating all of these reference
counts, sort them by byte number before actual updates are done.

Subject: [PATCH 1004/1079] Btrfs: disable leak debugging checks in extent_io.c

extent_io.c has debugging code to report and free leaked extent_state
and extent_buffer objects at rmmod time.  This helps track down
leaks and it saves you from rebooting just to properly remove the
kmem_cache object.

But, the code runs under a fairly expensive spinlock and the checks to
see if it is currently enabled are not entirely consistent.  Some use
#ifdef and some #if.

This changes everything to #if and disables the leak checking.

Subject: [PATCH 1005/1079] Btrfs: hash_lock is no longer needed

Before metadata is written to disk, it is updated to reflect that writeout
has begun.  Once this update is done, the block must be cow'd before it
can be modified again.

This update was originally synchronized by using a per-fs spinlock.  Today
the buffers for the metadata blocks are locked before writeout begins,
and everyone that tests the flag has the buffer locked as well.

So, the per-fs spinlock (called hash_lock for no good reason) is no
longer required.

Subject: [PATCH 1006/1079] Btrfs: Change btree locking to use explicit
 blocking points

Most of the btrfs metadata operations can be protected by a spinlock,
but some operations still need to schedule.

So far, btrfs has been using a mutex along with a trylock loop,
most of the time it is able to avoid going for the full mutex, so
the trylock loop is a big performance gain.

This commit is step one for getting rid of the blocking locks entirely.
btrfs_tree_lock takes a spinlock, and the code explicitly switches
to a blocking lock when it starts an operation that can schedule.

We'll be able get rid of the blocking locks in smaller pieces over time.
Tracing allows us to find the most common cause of blocking, so we
can start with the hot spots first.

The basic idea is:

btrfs_tree_lock() returns with the spin lock held

btrfs_set_lock_blocking() sets the EXTENT_BUFFER_BLOCKING bit in
the extent buffer flags, and then drops the spin lock.  The buffer is
still considered locked by all of the btrfs code.

If btrfs_tree_lock gets the spinlock but finds the blocking bit set, it drops
the spin lock and waits on a wait queue for the blocking bit to go away.

Much of the code that needs to set the blocking bit finishes without actually
blocking a good percentage of the time.  So, an adaptive spin is still
used against the blocking bit to avoid very high context switch rates.

btrfs_clear_lock_blocking() clears the blocking bit and returns
with the spinlock held again.

btrfs_tree_unlock() can be called on either blocking or spinning locks,
it does the right thing based on the blocking bit.

ctree.c has a helper function to set/clear all the locked buffers in a
path as blocking.

From bd56b30205bc09da0beb80d4ba3d4c7309792da5 Mon Sep 17 00:00:00 2001
From: Chris Mason <chris.mason@oracle.com>
Date: Wed, 4 Feb 2009 09:27:02 -0500
Subject: [PATCH 1007/1079] Btrfs: Make btrfs_drop_snapshot work in larger and
 more efficient chunks

Every transaction in btrfs creates a new snapshot, and then schedules the
snapshot from the last transaction for deletion.  Snapshot deletion
works by walking down the btree and dropping the reference counts
on each btree block during the walk.

If if a given leaf or node has a reference count greater than one,
the reference count is decremented and the subtree pointed to by that
node is ignored.

If the reference count is one, walking continues down into that node
or leaf, and the references of everything it points to are decremented.

The old code would try to work in small pieces, walking down the tree
until it found the lowest leaf or node to free and then returning.  This
was very friendly to the rest of the FS because it didn't have a huge
impact on other operations.

But it wouldn't always keep up with the rate that new commits added new
snapshots for deletion, and it wasn't very optimal for the extent
allocation tree because it wasn't finding leaves that were close together
on disk and processing them at the same time.

This changes things to walk down to a level 1 node and then process it
in bulk.  All the leaf pointers are sorted and the leaves are dropped
in order based on their extent number.

The extent allocation tree and commit code are now fast enough for
this kind of bulk processing to work without slowing the rest of the FS
down.  Overall it does less IO and is better able to keep up with
snapshot deletions under high load.

Subject: [PATCH 1009/1079] Btrfs: join the transaction in __btrfs_setxattr

With selinux on we end up calling __btrfs_setxattr when we create an inode,
which calls btrfs_start_transaction().  The problem is we've already called
that in btrfs_new_inode, and in btrfs_start_transaction we end up doing a
wait_current_trans().  If btrfs-transaction has started committing it will wait
for all handles to finish, while the other process is waiting for the
transaction to commit.  This is fixed by using btrfs_join_transaction, which
won't wait for the transaction to commit.  Thanks,

Subject: [PATCH 1010/1079] Btrfs: Don't try to compress pages past i_size

The compression code had some checks to make sure we were only
compressing bytes inside of i_size, but it wasn't catching every
case.  To make things worse, some incorrect math about the number
of bytes remaining would make it try to compress more pages than the
file really had.

The fix used here is to fall back to the non-compression code in this
case, which does all the proper cleanup of delalloc and other accounting.

Subject: [PATCH 1011/1079] Btrfs: Change btrfs_truncate_inode_items to stop
 when it hits the inode

btrfs_truncate_inode_items is setup to stop doing btree searches when
it has finished removing the items for the inode.  It used to detect the
end of the inode by looking for an objectid that didn't match the
one we were searching for.

But, this would result in an extra search through the btree, which
adds extra balancing and cow costs to the operation.

This commit adds a check to see if we found the inode item, which means
we can stop searching early.

btrfs_del_leaf does two things.  First it removes the pointer in the
parent, and then it frees the block that has the leaf.  It has the
parent node locked for both operations.

But, it only needs the parent locked while it is deleting the pointer.
After that it can safely free the block without the parent locked.

Subject: [PATCH 1014/1079] Btrfs: Only prep for btree deletion balances when
 nodes are mostly empty

Whenever an item deletion is done, we need to balance all the nodes
in the tree to make sure we don't end up with an empty node if a pointer
is deleted.  This balance prep happens from the root of the tree down
so we can drop our locks as we go.

reada_for_balance was triggering read-ahead on neighboring nodes even
when no balancing was required.  This adds an extra check to avoid
calling balance_level() and avoid reada_for_balance() when a balance
won't be required.

On fast devices that go from congested to uncongested very quickly, pdflush
is waiting too often in congestion_wait, and the FS is backing off to
easily in write_cache_pages.

For now, fix this on the btrfs side by only checking congestion after
some bios have already gone down.  Longer term a real fix is needed
for pdflush, but that is a larger project.

Subject: [PATCH 1017/1079] Revert "configfs: Silence lockdep on mkdir(),
 rmdir() and configfs_depend_item()"

This reverts commit 0e0333429a6280e6eb3c98845e4eed90d5f8078a.

I committed this by accident - Joel and Louis are working with the lockdep
maintainer to provide a better solution than just turning lockdep off.

Cleans uCode key table bit map iwl_clear_stations_table
since all stations are cleared also the key table must be.

Since the keys are not removed properly on suspend by mac80211
this may result in exhausting key table on resume leading
to memory corruption during removal

Subject: [PATCH 1027/1079] hpilo: open/close fix

The device can take a while to respond to an open/close request, so
increase the time kernel will wait for response (1 ms to 10ms).

Also, properly clean up a channel on a failed open, by calling the channel
close routine.  Just freeing the memory isn't sufficient, the device needs
to be informed that the channel is no longer open, and the device memory
cleared of references to freed dma buffer.

Subject: [PATCH 1031/1079] fbmem: don't call copy_from/to_user() with mutex
 held

Avoid calling copy_from/to_user() with fb_info->lock mutex held in fbmem
ioctl().

fb_mmap() is called under mm->mmap_sem (A) held, that also acquires
fb_info->lock (B); fb_ioctl() takes fb_info->lock (B) and does
copy_from/to_user() that might acquire mm->mmap_sem (A), causing a
deadlock.

NOTE: it doesn't push down the fb_info->lock in each own driver's
fb_ioctl(), so there are still potential deadlocks elsewhere.

Subject: [PATCH 1032/1079] shm: fix shmctl(SHM_INFO) lockup with !CONFIG_SHMEM

shm_get_stat() assumes that the inode is a "struct shmem_inode_info",
which is incorrect for !CONFIG_SHMEM (see fs/ramfs/inode.c:
ramfs_get_inode() vs.  mm/shmem.c: shmem_get_inode()).

This bad assumption can cause shmctl(SHM_INFO) to lockup when
shm_get_stat() tries to spin_lock(&info->lock).  Users of !CONFIG_SHMEM
may encounter this lockup simply by invoking the 'ipcs' command.

Subject: [PATCH 1033/1079] revert "rlimit: permit setting RLIMIT_NOFILE to
 RLIM_INFINITY"

Revert commit 0c2d64fb6cae9aae480f6a46cfe79f8d7d48b59f because it causes
(arguably poorly designed) existing userspace to spend interminable
periods closing billions of not-open file descriptors.

We could bring this back, with some sort of opt-in tunable in /proc, which
defaults to "off".

Peter's alanysis follows:

: I spent several hours trying to get to the bottom of a serious
: performance issue that appeared on one of our servers after upgrading to
: 2.6.28.  In the end it's what could be considered a userspace bug that
: was triggered by a change in 2.6.28.  Since this might also affect other
: people I figured I'd at least document what I found here, and maybe we
: can even do something about it:
:
:
: So, I upgraded some of debian.org's machines to 2.6.28.1 and immediately
: the team maintaining our ftp archive complained that one of their
: scripts that previously ran in a few minutes still hadn't even come
: close to being done after an hour or so.  Downgrading to 2.6.27 fixed
: that.
:
: Turns out that script is forking a lot and something in it or python or
: whereever closes all the file descriptors it doesn't want to pass on.
: That is, it starts at zero and goes up to ulimit -n/RLIMIT_NOFILE and
: closes them all with a few exceptions.
:
: Turns out that takes a long time when your limit -n is now 2^20 (1048576).
:
: With 2.6.27.* the ulimit -n was the standard 1024, but with 2.6.28 it is
: now a thousand times that.
:
: 2.6.28 included a patch titled "rlimit: permit setting RLIMIT_NOFILE to
: RLIM_INFINITY" (0c2d64fb6cae9aae480f6a46cfe79f8d7d48b59f)[1] that
: allows, as the title implies, to set the limit for number of files to
: infinity.
:
: Closer investigation showed that the broken default ulimit did not apply
: to "system" processes (like stuff started from init).  In the end I
: could establish that all processes that passed through pam_limit at one
: point had the bad resource limit.
:
: Apparently the pam library in Debian etch (4.0) initializes the limits
: to some default values when it doesn't have any settings in limit.conf
: to override them.  Turns out that for nofiles this is RLIM_INFINITY.
: Commenting out "case RLIMIT_NOFILE" in pam_limit.c:267 of our pam
: package version 0.79-5 fixes that - tho I'm not sure what side effects
: that has.
:
: Debian lenny (the upcoming 5.0 version) doesn't have this issue as it
: uses a different pam (version).

Subject: [PATCH 1040/1079] wait: prevent exclusive waiter starvation

With exclusive waiters, every process woken up through the wait queue must
ensure that the next waiter down the line is woken when it has finished.

Interruptible waiters don't do that when aborting due to a signal.  And if
an aborting waiter is concurrently woken up through the waitqueue, noone
will ever wake up the next waiter.

This has been observed with __wait_on_bit_lock() used by
lock_page_killable(): the first contender on the queue was aborting when
the actual lock holder woke it up concurrently.  The aborted contender
didn't acquire the lock and therefor never did an unlock followed by
waking up the next waiter.

Add abort_exclusive_wait() which removes the process' wait descriptor from
the waitqueue, iff still queued, or wakes up the next waiter otherwise.
It does so under the waitqueue lock.  Racing with a wake up means the
aborting process is either already woken (removed from the queue) and will
wake up the next waiter, or it will remove itself from the queue and the
concurrent wake up will apply to the next waiter after it.

Use abort_exclusive_wait() in __wait_event_interruptible_exclusive() and
__wait_on_bit_lock() when they were interrupted by other means than a wake
up through the queue.

Subject: [PATCH 1041/1079] do_wp_page: fix regression with execute in place

Fix do_wp_page for VM_MIXEDMAP mappings.

In the case where pfn_valid returns 0 for a pfn at the beginning of
do_wp_page and the mapping is not shared writable, the code branches to
label `gotten:' with old_page == NULL.

In case the vma is locked (vma->vm_flags & VM_LOCKED), lock_page,
clear_page_mlock, and unlock_page try to access the old_page.

This patch checks whether old_page is valid before it is dereferenced.

The regression was introduced by "mlock: mlocked pages are unevictable"
(commit b291f000393f5a0b679012b39d79fbc85c018233).

 sx_fw_ioctl()

If we return directly with -EPERM then lock_kernel() is still held.

This was found with a code checker (http://repo.or.cz/w/smatch.git/).

Subject: [PATCH 1048/1079] sgi-xp: fix writing past the end of kzalloc()'d
 space

A missing type cast results in writing way beyond the end of a kzalloc()'d
memory segment resulting in slab corruption. But it seems like the better
solution is to define ->recv_msg_slots as a 'void *' rather than a
'struct xpc_notify_mq_msg_uv *' and add the type cast.

Subject: [PATCH 1049/1079] seq_file: move traverse so it can be used from
 seq_read

In 2.6.25 some /proc files were converted to use the seq_file
infrastructure.  But seq_files do not correctly support pread(), which
broke some usersapce applications.

To handle pread correctly we can't assume that f_pos is where we left it
in seq_read.  So move traverse() so that we can eventually use it in
seq_read and do thus some day support pread().

Subject: [PATCH 1050/1079] seq_file: fix big-enough lseek() + read()

lseek() further than length of the file will leave stale ->index
(second-to-last during iteration). Next seq_read() will not notice
that ->f_pos is big enough to return 0, but will print last item
as if ->f_pos is pointing to it.

Introduced in commit cb510b8172602a66467f3551b4be1911f5a7c8c2
aka "seq_file: more atomicity in traverse()".

The UDP header pointer assignment must happen after calling
pskb_may_pull().  As pskb_may_pull() can potentially alter the SKB
buffer.

This was exposted by running multicast traffic through the NIU driver,
as it won't prepull the protocol headers into the linear area on
receive.

Subject: [PATCH 1056/1079] md: Allow read error in a single drive raid1 to be
 passed up.

If a raid1 only has a single working device and gets a read error,
we choose to simply return that error up to the filesystem (or whatever)
rather than failing the whole array.

However the codes doesn't quite do that.  We attempt a readbalance
which allocates the same drive, so we retry the read - indefinitely.

Instead:  If read_balance in the error case chooses the same drive that just
failed, treat it as a failure and don't retry.

Subject: [PATCH 1057/1079] md: Fix a bug in linear.c causing which_dev() to
 return the wrong device.

ab5bd5cbc8d4b868378d062eed3d4240930fbb86 introduced the following
bug in linear software raid for large arrays on 32 bit machines:

which_dev() computes the device holding a given sector by shifting
down the sector number to a 32 bit range, dividing by the array
spacing and looking up the resulting index in the hash table of
the array.

Because the computed index might be slightly too small, a loop at
the end of which_dev() increases the index until the given sector
actually falls into the range of the device associated with that index.

The changes of the above mentioned commit caused this loop to check
whether the _index_ rather than the sector number is small enough,
effectively bypassing the loop and thus possibly returning the wrong
device.

As reported by Simon Kirby, this leads to errors such as

	linear_make_request: Sector 2340486136 out of bounds on dev sdi: 156301312 sectors, offset 2109870464

Fix this bug by introducing a local variable for the index so that
the variable containing the passed sector is left unchanged.

Subject: [PATCH 1058/1079] md: Ensure an md array never has too many devices.

Each different metadata format supported by md supports a
different maximum number of devices.
We really should be enforcing this maximum in the kernel, but
we aren't quite doing that properly.

We currently only enforce it at the 'hot_add' point, which is an
older interface which is not used by current userspace.

We need to also enforce it at 'add_new_disk' time for active arrays
and at 'do_md_run' time when starting a new array.

So move the test from 'hot_add' into 'bind_rdev_to_array' which is
called from both 'hot_add' and 'add_new_disk, and add a new
test in 'analyse_sbs' which is called from 'do_md_run'.

This bug (or missing feature) has been around "forever" and so
the patch is suitable for any -stable that is currently maintained.

However, we must still read the maximum packet size from the standard

and therefore rejected by the USB core.

Subject: [PATCH 1067/1079] ACPI: delete CPU_IDLE=n code

CPU_IDLE=y has been default for ACPI=y since Nov-2007,
and has shipped in many distributions since then.

Here we delete the CPU_IDLE=n ACPI idle code, since
nobody should be using it, and we don't want to
maintain two versions.

Subject: [PATCH 1068/1079] ACPI: disable ACPI cleanly when bad RSDP found

When ACPI is disabled in the BIOS of this VIA C3 box,
it invalidates the RSDP, which Linux notices:

ACPI Error (tbxfroot-0218): A valid RSDP was not found [20080926]

Bug Linux neglected to disable ACPI at that stage,
and later scribbled on smp_found_config:

ACPI: No APIC-table, disabling MPS

But this box doesn't run well in legacy PIC mode,
it needed IOAPIC mode to perform correctly:

http://lkml.org/lkml/2009/2/5/39

So exit ACPI mode cleanly when we first detect
that it is hopeless.

Subject: [PATCH 1069/1079] vfs: Don't call attach_nobh_buffers() with an empty
 list

This is a modification of a patch by Bill Pemberton <wfp5p@virginia.edu>

nobh_write_end() could call attach_nobh_buffers() with head == NULL.
This would result in a trap when attach_nobh_buffers() attempted to
access bh->b_this_page.

This can be illustrated by running the writev01 testcase from LTP on jfs.

This error was introduced by commit 5b41e74a "vfs: fix data leak in
nobh_write_end()".  That patch did not take into account that if
PageMappedToDisk() is true upon entry to nobh_write_begin(), then no
buffers will be allocated for the page.  In that case, we won't have to
worry about a failed write leaving unitialized data in the page.

Of course, head != NULL implies !page_has_buffers(page), so no need to
test both.

Subject: [PATCH 1070/1079] elf core dump: fix get_user use

The elf_core_dump() code does its work with set_fs(KERNEL_DS) in force,
so vma_dump_size() needs to switch back with set_fs(USER_DS) to safely
use get_user() for a normal user-space address.

Checking for VM_READ optimizes out the case where get_user() would fail
anyway.  The vm_file check here was already superfluous given the control
flow earlier in the function, so that is a cleanup/optimization unrelated
to other changes but an obvious and trivial one.

Subject: [PATCH 1071/1079] x86-64: fix int $0x80 -ENOSYS return

One of my past fixes to this code introduced a different new bug.
When using 32-bit "int $0x80" entry for a bogus syscall number,
the return value is not correctly set to -ENOSYS.  This only happens
when neither syscall-audit nor syscall tracing is enabled (i.e., never
seen if auditd ever started).  Test program:

	/* gcc -o int80-badsys -m32 -g int80-badsys.c
	   Run on x86-64 kernel.
	   Note to reproduce the bug you need auditd never to have started.  */

	#include <errno.h>
	#include <stdio.h>

	int
	main (void)
	{
	  long res;
	  asm ("int $0x80" : "=a" (res) : "0" (99999));
	  printf ("bad syscall returns %ld\n", res);
	  return res != -ENOSYS;
	}

The fix makes the int $0x80 path match the sysenter and syscall paths.

Subject: [PATCH 1072/1079] eCryptfs: Regression in unencrypted filename
 symlinks

The addition of filename encryption caused a regression in unencrypted
filename symlink support.  ecryptfs_copy_filename() is used when dealing
with unencrypted filenames and it reported that the new, copied filename
was a character longer than it should have been.

This caused the return value of readlink() to count the NULL byte of the
symlink target.  Most applications don't care about the extra NULL byte,
but a version control system (bzr) helped in discovering the bug.

Subject: [PATCH 1073/1079] ACPI: dock: Don't eval _STA on every show_docked
 sysfs read

Some devices trigger a DEVICE_CHECK on every evalutation of _STA. This
can also be seen in commit 8b59560a3baf2e7c24e0fb92ea5d09eca92805db
(ACPI: dock: avoid check _STA method).  If an undock is processed, the
dock driver sends a uevent and userspace might read the show_docked
property in sysfs. This causes an evaluation of _STA of the particular
device which causes the dock driver to immediately dock again.

In any case, evaluation of _STA (show_docked) does not necessarily mean
that we are docked, so check with the internal device structure.

Subject: [PATCH 1076/1079] ACPI: Enable bit 11 in _PDC to advertise hw coord

Bit 11 in intel PDC definitions is meant for OS capability to handle
hardware coordination of P-states. In Linux we have always supported
hwardware coordination of P-states. Just let the BIOSes know that we
support it, by setting this bit.

Some BIOSes use this bit to choose between hardware or software coordination
and without this change below, BIOSes switch to software coordination, which
is not very optimal in terms of power consumption and extra wakeups from idle.

Subject: [PATCH 1077/1079] ACPICA: Fix table entry truncation calculation

During early boot, ACPI RSDT/XSDT table entries are gathered into the
'initial_tables[]' array.  This array is currently statically defined (see
./drivers/acpi/tables.c).  When there are more table entries than can be
held in the 'initial_tables[]' array, the message "Truncating N table
entries!" is output.  As currently implemented, this message will always
erroneously calculate N as 0.

This patch fixes the calculation that determines how many table entries
will be missing (truncated).

This modification may be used under either the GPL or the BSD-style
license used for Intel ACPI CA code.

Subject: [PATCH 1078/1079] eeepc-laptop: fix oops when changing backlight
 brightness during eeepc-laptop init

I got the following oops while changing the backlight brightness during
startup.  When it happens, it prevents use of the hotkeys, Fn-Fx, and the
lid button.

It's a clear use-before-init, as I verified by testing with an
appropriately-placed "else printk".
