Dave just pulled in all outstanding pull requests, so just basing on top
of his drm-next should be good enough.

We atm don't have it :( drm-misc was kinda just a (very long running)
experiment, but I want to know make it official. Unfortunately the
scripting rework to split out a new drm-misc.git repo is taking a bit
longer. Atm things are still in flux, but I hope that'll settle soon-ish.

Yeah, that's the new location, but atm it's just under testing and it's
not the real drm-misc. That one is in drm-intel.git, in the topic/drm-misc
branch.

We need to flesh that out, and maybe feature it a bit more prominently.
