Merge tag 'topic/core-stuff-2014-05-05' of git://anongit.freedesktop.org/drm-intel into drm-next

Update pull request with drm core patches. Mostly some polish for the
primary plane stuff and a pile of patches all over from Thierry. Has
survived a few days in drm-intel-nightly without causing ill.

I've frobbed my scripts a bit to also tag my topic branches so that you
have something stable to pull - I've accidentally pushed a bunch more
patches onto this branch before you've taken the old pull request.
