Merge tag 'drm-intel-next-2013-12-13' of git://people.freedesktop.org/~danvet/drm-intel into drm-next
- fbc1 improvements from Ville (pre-gm45).
- vlv forcewake improvements from Deepak S.
- Some corner-cases fixes from Mika for the context hang stat code.
- pc8 improvements and prep work for runtime D3 from Paulo, almost ready for
primetime.
- gen2 dpll fixes from Ville.
- DSI improvements from Shobhit Kumar.
- A few smaller fixes and improvements all over.
[airlied: intel_ddi.c conflict fixed up]
