Merge tag 'topic/drm-misc-2016-06-01' of git://anongit.freedesktop.org/drm-intel into drm-next
Frist -misc pull for 4.8, with pretty much just random all over plus a few
more lockless gem BO patches acked/reviewed by driver maintainers.
I'm starting a bit earlier this time around because there's a few invasive
patch series to land (nonblocking atomic prep work, fence prep work,
rst/sphinx kerneldoc finally happening) and I need a baseline with all the
branches merged.
