commit c8415a48fcb7a29889f4405d38c57db351e4b50a upstream.

As with the ThinkPad Models X230 Tablet and T530 the X230 needs a qurik to
correctly set up the pins for the dock port.

md/raid1: don't abort a resync on the first badblock.

commit b7219ccb33aa0df9949a60c68b5e9f712615e56f upstream.

If a resync of a RAID1 array with 2 devices finds a known bad block
one device it will neither read from, or write to, that device for
this block offset.
So there will be one read_target (The other device) and zero write
targets.
This condition causes md/raid1 to abort the resync assuming that it
has finished - without known bad blocks this would be true.

When there are no write targets because of the presence of bad blocks
we should only skip over the area covered by the bad block.
RAID10 already gets this right, raid1 doesn't.  Or didn't.

As this can cause a 'sync' to abort early and appear to have succeeded
it could lead to some data corruption, so it suitable for -stable.

video/smscufx: fix line counting in fb_write

commit 2fe2d9f47cfe1a3e66e7d087368b3d7155b04c15 upstream.

Line 0 and 1 were both written to line 0 (on the display) and all subsequent
lines had an offset of -1. The result was that the last line on the display
was never overwritten by writes to /dev/fbN.

The origin of this bug seems to have been udlfb.

ore: Fix out-of-bounds access in _ios_obj()

commit 9e62bb4458ad2cf28bd701aa5fab380b846db326 upstream.

_ios_obj() is accessed by group_index not device_table index.

The oc->comps array is only a group_full of devices at a time
it is not like ore_comp_dev() which is indexed by a global
device_table index.

This did not BUG until now because exofs only uses a single
COMP for all devices. But with other FSs like PanFS this is
not true.

This bug was only in the write_path, all other users were
using it correctly

[This is a bug since 3.2 Kernel]

ath9k: Add PID/VID support for AR1111

commit d4e5979c0da95791aa717c18e162540c7a596360 upstream.

AR1111 is same as AR9485. The h/w
difference between them is quite insignificant,
Felix suggests only very few baseband features
may not be available in AR1111. The h/w code for
AR9485 is already present, so AR1111 should
work fine with the addition of its PID/VID.

wireless: reg: restore previous behaviour of chan->max_power calculations

commit 5e31fc0815a4e2c72b1b495fe7a0d8f9bfb9e4b4 upstream.

commit eccc068e8e84c8fe997115629925e0422a98e4de
Author: Hong Wu <Hong.Wu@dspg.com>
Date:   Wed Jan 11 20:33:39 2012 +0200

    wireless: Save original maximum regulatory transmission power for the calucation of the local maximum transmit pow

changed the way we calculate chan->max_power as min(chan->max_power,
chan->max_reg_power). That broke rt2x00 (and perhaps some other
drivers) that do not set chan->max_power. It is not so easy to fix this
problem correctly in rt2x00.

According to commit eccc068e8 changelog, change claim only to save
maximum regulatory power - changing setting of chan->max_power was side
effect. This patch restore previous calculations of chan->max_power and
do not touch chan->max_reg_power.

x86, nops: Missing break resulting in incorrect selection on Intel

commit d6250a3f12edb3a86db9598ffeca3de8b4a219e9 upstream.

The Intel case falls through into the generic case which then changes
the values.  For cases like the P6 it doesn't do the right thing so
this seems to be a screwup.

commit 9dccf55f4cb011a7552a8a2749a580662f5ed8ed upstream.

The tamper evident features of the RTC include the "write counter" which
is a pseudo-random number regenerated whenever we set the RTC. Since this
value is unpredictable it should provide some useful seeding to the random
number generator.

Only do this on boot since the goal is to seed the pool rather than add
useful entropy.
