Merge tag 'topic/drm-misc-2015-05-19' of git://anongit.freedesktop.org/drm-intel into drm-next

Scattering of random drm core patches. Bunch of atomic prep work too, but
the final bits for blob properties, atomic modesets and lifting the
experimental tag on the atomic ioctl are still blocked on Daniel Stone
finalizing and testing the weston support for it. I hope that we can get
it all ready for 4.2 though.
