Subject: [PATCH 0/7] kms + kgdb & kdb proposed merge for 2.6.34

Patch set 2 of 3 - The kdb / kgdb merge

This patch set stacks on top of the kgdb / kdb patches and focuses on
further extending kdb to accommodate atomic kernel mode setting (kms).

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

The final patch in the series would be omitted from any pull request
as it is still a work in progress, showing the remaining points that do
not have a safe mechanism to work atomically to change the display
context in order to view the kernel debugger shell.  At least it
provides a nice proof of concept.

You can find the development branch for this here:

Thanks,
Jason.
