Subject: [GIT PULL] kgdb,kdb,kms for 2.6.36 (2 of 2)

Linus please pull the kms-merge branch which merges the atomic kernel
mode setting hooks into the kernel debugger.

git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/linux-2.6-kgdb.git kms-merge

--- Notes for Linus ---

All the code patches are acked or signed off by Jesse Barnes as this
patch set was co-developed and tested by each of us.  These patches
are not in the drm git tree due to the dependence to kgdb/kdb patches.

--- End Notes for Linus ---

This patch set stacks on top of the kgdb / kdb patches and focuses on
further extending kdb to accommodate atomic kernel mode setting (kms).
The idea is that simply setting "kgdboc=kms,kbd" as a kernel argument
will allow you to catch a panic, kernel fault, or jump into the kernel
debugger shell from a graphics console session.

At the moment only the Intel i915 class video devices are supported,
but the API is generic and allows for other kms based drivers to
enable atomic mode setting.

Thanks,
Jason.
