[SRU] [Karmic] fix volume hotkeys for Dell Studio 1557

Impact:
	On the Dell Studio 1557 if you press any of the volume keys they will
not give a release and press infinitely.
https://bugs.launchpad.net/bugs/465250

Fix:
	Patch attached adds quirk to fix hotkeys for 2.6.31. 

	Though for 2.6.32 & upstream this fix is expected to go into udev.
Though Lucid has not pulled in a recent version supporting this
functionality.

Testcase:
	Pressing volume keys will not infinitely generate key presses.

Fix volume hotkeys for Dell Studio 1157 generating infinite key presses.

Re: Likely Duplicate Bugs

Hi Brian,

This kernel message are dups of the same BIOS corruption message, but
occurs on a wide range of machines. I had a look at the first 15 or so
of the dups and saw that there was a wide spread of Aspire, HP Compaqs
and Pavilions and quite a number of unknown systems too.

Specifically, the kernel fills known regions of the low 64K of memory
with a known pattern and periodically monitors them.  Any buggy BIOS
that writes to these regions gets detected and the warning is issued.

BIOS corruption of these regions can occur when doing suspend/resume or
HDMI cable unplugging.

The error message is a warning - the system's stability is not
compromised as the pages being monitored are already reserved for the
purpose of being monitored for corruption in the first place.

This check can be disabled by setting the kernel boot parameter
memory_corruption_check=0

Since this is intended as a BIOS corruption detection tool perhaps it
should be disabled as a compile time option to stop getting these
messages. However, it does have some value in showing that the BIOS may
be dodgy. 

Colin

[PATCH 0/2] UBUNTU: [Config] Enable CONFIG_DEBUG_KERNEL for ARM branch and CONFIG_TIMER_STATS for fsl-imx51 branch

In bug #513241, CONFIG_TIMER_STATS needs to be turned on for supporting
powertop application on ARM hardware. Since CONFIG_TIMER_STATS depends on
CONFIG_DEBUG_KERNEL, we need to enable CONFIG_DEBUG_KERNEL firstly.

The first patch can be shared with all ARM branches, the second patch is
simply enabling it on fsl-imx51 kernel. Please git pull from:
 git://kernel.ubuntu.com/roc/ubuntu-lucid lp513241_config_timer_stats

[PATCH 1/2] UBUNTU: [Config] Enable CONFIG_DEBUG_KERNEL for ARM branch

BugLink: http://bugs.launchpad.net/bugs/513241

We need to enable CONFIG_TIMER_STATS to use powertop properly on ARM hardware.
But CONFIG_TIMER_STATS depends on CONFIG_DEBUG_KERNEL. So we turn on this
option here as well as x86 branches.

This patch can share with all ARM branches

[PATCH 2/2] UBUNTU: [Config] Enable CONFIG_TIMER_STATS for fsl-imx51 kernel

BugLink: http://bugs.launchpad.net/bugs/513241

For using powertop on armel hardware (at least for the bits and pieces where
it can gather data on non x86 HW), it needs to enable CONFIG_TIMER_STATS.

Ok, won't have impact on the main tree and looks sane.
