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.
