Merge tag 'drm-for-v4.14' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"This is the main drm pull request for 4.14 merge window.
I'm sending this early, as my continuing journey into fatherhood is
occurring really soon now, I'm going to be mostly useless for the next
couple of weeks, though I may be able to read email, I doubt I'll be
doing much patch applications or git sending. If anything urgent pops
up I've asked Daniel/Jani/Alex/Sean to try and direct stuff towards
you.
Outside drm changes:
Some rcar-du updates that touch the V4L tree, all acks should be in
place. It adds one export to the radix tree code for new i915 use
case. There are some minor AGP cleanups (don't see that too often).
Changes to the vbox driver in staging to avoid breaking compilation.
