Merge remote-tracking branch 'airlied/drm-next' into topic/vblank-rework
Dave asked me to do the backmerge before sending him the revised pull request, so here we go. Nothing fancy in the conflicts, just a few things changed right next to each another. Conflicts: drivers/gpu/drm/drm_irq.c Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
