Merge remote-tracking branch 'airlied/drm-next' into drm-intel-next

The conflict in intel_drv.h tripped me up a bit since a patch in dinq
moves all the functions around, but another one in drm-next removes a
single function. So I'ev figured backing this into a backmerge would
be good.

i915_dma.c is just adjacent lines changed, nothing nefarious there.

Conflicts:
	drivers/gpu/drm/i915/i915_dma.c
	drivers/gpu/drm/i915/intel_drv.h
