[git pull] drm fixes

[Dave Airlie]

Hi Linus,

3 fixes, one for an ongoing Intel VT-d/Ironlake GPU that I've been 
testing, and one kexec fix from Jerome for an issue reported on the list
where the gpu writeback engines need to be switched off, along with a 
trivial fix from Alex.

Due to the size of the kexec fix I've decided to keep this pull small.
(I have some kzalloc->kcalloc fixes to check on).

Dave.
