Merge tag 'topic/drm-misc-2016-11-10' of git://anongit.freedesktop.org/drm-intel into drm-next

- better atomic state debugging from Rob
- fence prep from gustavo
- sumits flushed out his backlog of pending dma-buf/fence patches from
  various people
- drm_mm leak debugging plus trying to appease Kconfig (Chris)
- a few misc things all over
