One of the legit warnings 'make W=3 drivers/ide/ide-cd.c'
generates is:
drivers/ide/ide-cd.c: In function ide_cd_do_request
drivers/ide/ide-cd.c:828:2: warning: conversion to int from \
unsigned int may change the sign of the result
drivers/ide/ide-cd.c:833:2: warning: conversion to int from \
unsigned int may change the sign of the result
nsectors is declared int, should be unsigned int.
blk_rq_sectors() returns unsigned int, and ide_complete_rq
expects unsigned int as well. Fixes both warnings.

The mach-nomadik machine did not compile properly due to bad
ux500-specific functions being called. Introduce new state

Commit a197b59ae6e8 (mm: fail GFP_DMA allocations when ZONE_DMA is not

CONFIG_ZONE_DMA is disabled.

Since there is no restrictions for DMA on ep93xx, we can fix this by just
removing the GFP_DMA flag from the call.

We can use simply kmalloc() to allocate the buffers. This also simplifies the
code and allows us to perform DMA sync operations more easily.
Memory is allocated with only GFP_KERNEL since there are no DMA allocation
restrictions on this platform.

We use priv->mutex to avoid race conditions between chswitch_done()
and mac_channel_switch(), when marking channel switch in
progress. But chswitch_done() can be called in atomic context
from rx_csa() or with mutex already taken from commit_rxon().
To fix remove mutex from chswitch_done() and use atomic bitops
for marking channel switch pending.

Setting tx power can be deferred during scan or changing channel.
If after that correct tx power settings will not be sent to device,
we can observe transmission problems and timeouts. Force to send
tx power settings also after partial rxon change, to assure device
always be configured with up-to-date settings.

This patch fixes 802.11n stability and performance regression we have
since 2.6.35. It boost performance on my 5GHz N-only network from about
5MB/s to 8MB/s. Similar percentage boost can be observed on 2.4 GHz.
These are test results of 5x downloading of approximately 700MB iso
image:
vanilla: 5.27 5.22 4.94 4.47 5.31 ; avr 5.0420 std 0.35110
patched: 8.07 7.95 8.06 7.99 7.96 ; avr 8.0060 std 0.055946
This was achieved with NetworkManager configured to do not perform
periodical scans, by configuring constant BSSID. With periodical scans,
after some time, performance downgrade to unpatched driver level, like
in example below:
patched: 7.40 7.61 4.28 4.37 4.80 avr 5.6920 std 1.6683
However patch still make better here, since similar test on unpatched
driver make link disconnects with below messages after some time:
wlan1: authenticate with 00:23:69:35:d1:3f (try 1)
wlan1: authenticate with 00:23:69:35:d1:3f (try 2)
wlan1: authenticate with 00:23:69:35:d1:3f (try 3)
wlan1: authentication with 00:23:69:35:d1:3f timed out
On 2.6.35 kernel patch helps against connection hangs with messages:
iwlagn 0000:20:00.0: queue 10 stuck 3 time. Fw reload.
iwlagn 0000:20:00.0: On demand firmware reload

When SR-IOV is enabled, i350 devices fail to pass traffic. This is due to
the driver attempting to enable RSS on the PF device, which is not
supported by the i350.
When max_vfs is specified on an i350 adapter, set the number of RSS queues
to 1.
This issue affects 2.6.39 as well.

Commit 06e8935febe687e2a561707d4c7ca4245d261dbe adds an IRQ handling
optimization for single-function SDIO cards like this one, but at the
same time exposes a small hardware bug.
During hardware init, an interrupt is generated with (apparently) no
source. Previously, mmc threw this interrupt away, but now (due to the
optimization), the mmc layer passes this onto libertas, before it is ready
(and before it has enabled interrupts), causing a crash.
Work around this hardware bug by registering the IRQ handler later and
making it capable of handling interrupts with no cause. The change that
makes the IRQ handler registration happen later actually eliminates
the spurious interrupt as well.

Disable fast channel change by default on AR2413/AR5413 due to
some bug reports (it still works for me but it's better to be safe).
Add a module parameter "fastchanswitch" in case anyone wants to enable
it and play with it.

The bonding driver is multiqueue enabled, in which each queue represents a slave
to enable optional steering of output frames to given slaves against the default
output policy. However, it needs to reset the skb->queue_mapping prior to
queuing to the physical device or the physical slave (if it is multiqueue) could
wind up transmitting on an unintended tx queue
Change Notes:
v2) Based on first pass review, updated the patch to restore the origional queue
mapping that was found in bond_select_queue, rather than simply resetting to
zero. This preserves the value of queue_mapping when it was set on receive in
the forwarding case which is desireable.
v3) Fixed spelling an casting error in skb->cb
v4) fixed to store raw queue_mapping to avoid double decrement
v5) Eric D requested that ->cb access be wrapped in a macro.

To work around controllers which can't properly plug events while
reset, ata_eh_reset() clears error states and ATA_PFLAG_EH_PENDING
after reset but before RESET is marked done. As reset is the final
recovery action and full verification of devices including onlineness
and classfication match is done afterwards, this shouldn't lead to
lost devices or missed hotplug events.
Unfortunately, it forgot to thaw the port when clearing EH_PENDING, so
if the condition happens after resetting an empty port, the port could
be left frozen and EH will end without thawing it, making the port
unresponsive to further hotplug events.
Thaw if the port is frozen after clearing EH_PENDING. This problem is
reported by Bruce Stenning in the following thread.
http://thread.gmane.org/gmane.linux.kernel/1123265
stable: I think we should weather this patch a bit longer in -rcX

The cx23885 driver was including staging/altera.h, but that file has
moved back into the driver directory.
Why a non-staging driver was including a staging driver is beyond me,
but this fixes the build so everything is happy for now.
For the record, it's not ok for a non-staging driver to depend on a
staging one, as that implies that the non-staging one should also be in
the staging tree if that's needed.

The kernel panic happens when we try to complete a pending
scan request while going to suspend state. The cause for this
kernel panic is accessing a freed memory (ar->arWmin). This
is freed before ar6k_cfg80211_scanComplete_event() getting
called where it is dereferenced.

Many Linux distributions would enable vesafb in order to display
early stage boot splash. In this case, we will get garbled X
Window screen if running X fbdev on psbfb.
This is because fb0 is occupied by vesafb while psbfb is on fb1.
They tried to drive the same pieces of hardware at the same
time. With unmodified X start-up, it would try to use default
fb0 framebuffer device and unfortunately it is now broken
becaues fb1 supersedes it.
We should let psbfb takeover framebuffer control from vesafb
to get around this problem.

On the Fit-PC2 the VBT reports an invalid fixed panel mode for LVDS, this gets
in the way for SDVO. This patch makes VBT parsing skip the invalid mode. When
there is no LVDS output the backlight support crashes so the patch also checks
for this before enabling it.

Implemented pre_reset and post_reset methods of the driver to prevent the
driver from being unbound upon a device reset. Because of this also the
asynchronous reset introduced to prevent a race condition is no longer necessary
(and sometimes causes problems, because it comes later then expected).
