drm-intel-next-2014-11-21:
- infoframe tracking (for fastboot) from Jesse
- start of the dri1/ums support removal
- vlv forcewake timeout fixes (Imre)
- bunch of patches to polish the rps code (Imre) and improve it on bdw (Tom
O'Rourke)
- on-demand pinning for execlist contexts
- vlv/chv backlight improvements (Ville)
- gen8+ render ctx w/a work from various people
- skl edp programming (Satheeshakrishna et al.)
- psr docbook (Rodrigo)
- piles of little fixes and improvements all over, as usual
