Merge remote branch 'origin/master' into drm-intel-next
Conflicts: drivers/gpu/drm/i915/i915_dma.c drivers/gpu/drm/i915/i915_drv.h drivers/gpu/drm/radeon/r300.c The BSD ringbuffer support that is landing in this branch significantly conflicts with the Ironlake PIPE_CONTROL fix on master, and requires it to be tested successfully anyway.
