The stable team requires a reference to the sha1 of the upstream
commit, which your patches seem to lack. git cherry-pick -x
automatically adds that for you.

Also please don't send out backports to stable if we still want to do
some testing on them. Adding Greg and stable so he knows that he can
bin this series for now. Of course all the patches in here which
already have cc: stable in upstream should still go through the normal
process (presuming they don't conflict ofc). But since most of these
patches are from drm-intel-next we must wait anyway until drm-next has
been merged into Linus' tree.

Thanks, Daniel
