Ok I've implemented this and added a new for-linux-next-fixes branch which
should only contain drm/i915 -fixes that apply on top of linus git and
nothing from Dave's drm tree. Please yell if this branch contains stuff
you don't want to see there. Atm it's just v3.11 since all the stuff on
tops of Dave's drm-next is in for-linux-next (and drm-next also isn't yet
merged).

Thanks, Daniel
