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.
