Is that pull request already on the list and/or in drm-next? Chris' patch
fell a bit through the cracks, but since it's fairly big I'd like to get
it into 4.11 still if possible, instead of keeping it in drm-misc for a
few weeks to route around the merge window blackout ...

Otherwise I guess 4.12 it is, but I'll still push it into drm-misc-next
next week if possible (we have drm-misc-next-fixes for bugfixes for the
merge window, to be able to keep merging feature work).
