Peilin, can you pls resend this together with all the other pending
patches from you? I think that's better than me trying to cherry-pick the
bits we decided to keep from random places.

Greg, ok if I just pull these in through drm-misc-next? It's a pretty bad
hairball anyway and that avoids the tree coordination issues. Only thing
that might get in the way is the vt font_copy removal, but that's in -rc3
so easy to backmerge.
