Merge tag 'drm-intel-next-2014-07-25-merged' of git://anongit.freedesktop.org/drm-intel into drm-next

Final feature pull for 3.17.

drm-intel-next-2014-07-25:
- Ditch UMS support (well just the config option for now)
- Prep work for future platforms (Sonika Jindal, Damien)
- runtime pm/soix fixes (Paulo, Jesse)
- psr tracking improvements, locking fixes, now enabled by default!
- rps fixes for chv (Deepak, Ville)
- drm core patches for rotation support (Ville, Sagar Kamble) - the i915 parts
  unfortunately didn't make it yet
- userptr fixes (Chris)
- minimum backlight brightness (Jani), acked long ago by Matthew Garret on irc -
  I've forgotten about this patch :(

QA is a bit unhappy about the DP MST stuff since it broke hpd testing a
bit, but otherwise looks sane. I've backmerged drm-next to resolve
conflicts with the mst stuff, which means the new tag itself doesn't
contain the overview as usual.
