drm/vbl rework: rework how the drm deals with vblank.
Other Authors: Michel Dänzer <michel@tungstengraphics.com>
mga: Ian Romanick <idr@us.ibm.com>
via: Thomas Hellstrom <thomas-at-tungstengraphics-dot-com>
This re-works the DRM internals to provide a better interface for drivers
to expose vblank on multiple crtcs.
It also includes work done by Michel on making i915 triple buffering and pageflipping work properly.
