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 :-) Core: Lockless GEM BO freeing Non-blocking atomic work Documentation changes (rst/sphinx) Prep for new fencing changes Simple display helpers Master/auth changes Register/unregister rework Loads of trivial patches/fixes.
