drm-intel-next-2014-04-16:
- vlv infoframe fixes from Jesse
- dsi/mipi fixes from Shobhit
- gen8 pageflip fixes for LRI/SRM from Damien
- cmd parser fixes from Brad Volkin
- some prep patches for CHV, DRRS, ...
- and tons of little things all over
drm-intel-next-2014-04-04:
- cmd parser for gen7 but only in enforcing and not yet granting mode - the
  batch copying stuff is still missing. Also performance is a bit ... rough
  (Brad Volkin + OACONTROL fix from Ken).
- deprecate UMS harder (i.e. CONFIG_BROKEN)
- interrupt rework from Paulo Zanoni
- runtime PM support for bdw and snb, again from Paulo
- a pile of refactorings from various people all over the place to prep for new
  stuff (irq reworks, power domain polish, ...)
