d06221c061 nouveau/bios: Fix tracking of BIOS image data
The code tries various methods for retreiving the BIOS data. However
it doesn't clear the bios->data pointer between the iterations.

In some cases, the shadow() method will fail and not update bios->data
at all, which will cause us to "score" the old data and incorrectly
attribute that score to the new method. This can cause double frees
later when disposing of the unused data.

Additionally, we were not freeing the data for methods that fail the
score test (we only freed when a "best" is superseeded, not when the
new method has a lower score than the exising "best"). Fix that as well.

ea71f98d68 nouveau: Fix crash when pci_ram_rom() returns a size of 0
From b15b244d6e6e20964bd4b85306722cb60c3c0809 Mon Sep 17 00:00:00 2001
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Date: Mon, 2 Apr 2012 13:28:18 +1000
Subject:

Under some circumstances, pci_map_rom() can return a valid mapping
but a size of 0 (if it cannot find an image in the header).

This causes nouveau to try to kmalloc() a 0 sized pointer and
dereference it, which crashes.

72331bc0cd ipv6: Fix RTM_GETROUTE's interpretation of RTA_IIF to be consistent with ipv4
In IPv4, if an RTA_IIF attribute is specified within an RTM_GETROUTE
message, then a route is searched as if a packet was received on the
specified 'iif' interface.

However in IPv6, RTA_IIF is not interpreted in the same way:
'inet6_rtm_getroute()' always calls 'ip6_route_output()', regardless the
RTA_IIF attribute.

As a result, in IPv6 there's no way to use RTM_GETROUTE in order to look
for a route as if a packet was received on a specific interface.

Fix 'inet6_rtm_getroute()' so that RTA_IIF is interpreted as "lookup a
route as if a packet was received on the specified interface", similar
to IPv4's 'inet_rtm_getroute()' interpretation.

67378563df net/garp: avoid infinite loop if attribute already exists
An infinite loop occurred if garp_attr_create was called with the values
of an existing attribute. This might happen if a previous leave request
for the attribute has not yet been followed by a PDU transmission (or,
if the application previously issued a join request for the attribute
and is now issuing another one, without having issued a leave request).

If garp_attr_create finds an existing attribute having the same values,
return the address to it. Its state will then get updated (i.e., if it
was in a leaving state, it will move into a non-leaving state and not
get deleted during the next PDU transmission).

To accomplish this fix, collapse garp_attr_insert into garp_attr_create
(which is its only caller).

66189be74f CIFS: Fix VFS lock usage for oplocked files
We can deadlock if we have a write oplock and two processes
use the same file handle. In this case the first process can't
unlock its lock if the second process blocked on the lock in the
same time.

Fix it by using posix_lock_file rather than posix_lock_file_wait
under cinode->lock_mutex. If we request a blocking lock and
posix_lock_file indicates that there is another lock that prevents
us, wait untill that lock is released and restart our call.

31e354ee65 hwmon: (acpi_power_meter) fix lockdep spew due to non-static lock class
Similar to a30dcb4f which fixed asus_atk0110.ko, I recently received a
bug report from someone hitting the same issue in acpi_power_meter.

[   13.963168] power_meter ACPI000D:00: Found ACPI power meter.
[   13.963900] BUG: key ffff8802161f3920 not in .data!
[   13.963904] ------------[ cut here ]------------
[   13.963915] WARNING: at kernel/lockdep.c:2986
	lockdep_init_map+0x52f/0x560()

So let's fix that up for them by statically declaring the
lockdep_class_key.

ce15a81da3 hwmon: (adm1031) Fix compiler warning
Some configurations produce the following compile warning:

drivers/hwmon/adm1031.c: In function 'set_fan_auto_channel':
drivers/hwmon/adm1031.c:292: warning: 'reg' may be used uninitialized in this function

While this is a false positive, it can easily be fixed by overloading the return
value from get_fan_auto_nearest with both register value and error return code
(the register value is never negative). Coincidentially, that also reduces
module size by a few bytes.

6394011d65 hwmon: (f75375s) Fix warning message seen in some configurations
In some configurations, BUG() does not result in an endless loop but returns to
the caller. This results in the following compiler warning:

drivers/hwmon/f75375s.c: In function 'duty_mode_enabled':
drivers/hwmon/f75375s.c:280: warning: control reaches end of non-void function
drivers/hwmon/f75375s.c: In function 'auto_mode_enabled':
drivers/hwmon/f75375s.c:295: warning: control reaches end of non-void function

Fix the warning by returning something sensible after BUG().

4b4e9e43fd regmap: rbtree: Fix register default look-up in sync
The code currently passes the register offset in the current block to
regcache_lookup_reg. This works fine as long as there is only one block and with
base register of 0, but in all other cases it will look-up the default for a
wrong register, which can cause unnecessary register writes. This patch fixes
it by passing the actual register number to regcache_lookup_reg.

e77166b5a6 drm/i915: properly clear SSC1 bit in the pch refclock init code
Noticed by staring at intel_reg_dumper diffs. Unfortunately it does
not seem to completely fix the bug.

Still, it's good to get this right, and maybe it helps someplace else.

1c7eaac737 drm/i915: apply CS reg readback trick against missed IRQ on snb
Ben Widawsky reported missed IRQ issues and this patch here helps.

We have one other missed IRQ report still left on snb, reported by QA:

https://bugs.freedesktop.org/show_bug.cgi?id=46145

This is _not_ a regression due to the forcewake voodoo though, it
started showing up before that was applied and has been on-and-off for
the past few weeks. According to QA this patch does not help. But the
missed IRQ is always from the blt ring (despite running piglit, so
also render activity expected), so I'm hopefully that this is an issue
with the blt ring itself.
