- corner-case fixes for runtime pm (Imre)
- tons of vblank improvements from Ville
- prep work for atomic plane/sprite updates (Ville)
- more chv code, now almost complete (tons of different people)
- refactoring and improvements for drm_irq.c merged through drm-intel-next
- g4x/ilk reset improvements (Ville)
- removal of encoder->mode_set
- moved audio state tracking into pipe_config
- shuffled fb pinning out of the platform crtc modeset callbacks into core code
- userptr support (Chris)
