Merge tag 'drm-for-v4.8' of git://people.freedesktop.org/~airlied/linux
Merge drm updates from Dave Airlie:
"This is the main drm pull request for 4.8.
I'm down with a cold at the moment so hopefully this isn't in too bad
a state, I finished pulling stuff last week mostly (nouveau fixes just
went in today), so only this message should be influenced by illness.
Apologies to anyone who's major feature I missed :-)
