Subject: [git pull] drm fixes for 2.6.27-rc1


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.
