Merge commit '9e9a928eed8796a0a1aaed7e0b676db86ba84594' into drm-next
Merge drm-fixes into drm-next. Both i915 and radeon need this done for later patches. Conflicts: drivers/gpu/drm/drm_crtc_helper.c drivers/gpu/drm/i915/i915_drv.h drivers/gpu/drm/i915/i915_gem.c drivers/gpu/drm/i915/i915_gem_execbuffer.c drivers/gpu/drm/i915/i915_gem_gtt.c
