Hi Linus,
Please pull the 'drm-next' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-next
This contains a lot of stability fixes from Intel for the GEM work along
with fixing some general drm issues.
Keith is working on a patchset to implement the new IO stuff, which we can
discuss later if it needs to hit 2.6.27 or if .28 is good enough.
Dave.

drm/i915: use pipes, not planes to label vblank data
vblank in the kernel is far simpler if it deals with pipes instead of
planes, so we're changing both user and kernel side.

drm/i915: hold dev->struct_mutex and DRM lock during vblank ring operations
To synchronize clip lists with the X server, the DRM lock must be held while
looking at drawable clip lists. To synchronize with other ring access, the
ring mutex must be held while inserting commands into the ring. Failure to
do the first resulted in easy visual corruption when moving windows, and the
second could have corrupted the ring with DRI2.
Grabbing the DRM lock involves using the DRM tasklet mechanism, grabbing the
ring mutex means potentially sleeping. Deal with both of these by always
running the tasklet from a work handler.
Also, protect from clip list changes since the vblank request was queued by
making sure the window has at least one rectangle while looking inside,
preventing oopses .

i915: Enable IMR passthrough of vblank events before enabling it in pipestat.
Otherwise, if we lost the race, the pipestat bit would be set without being
reflected in IIR, and we would never clear the pipestat bit so the pipe
event would never be generated again, and all vblank waits would time out.
