Merge branch 'topic/drm-vblank-rework' into drm-intel-next-queued 

Pull in the drm vblank rework from Ville and me. drm core parts acked
by Dave Airlie

Conflicts:
	drivers/gpu/drm/i915/intel_display.c

Just a bit of fun around the placement of drm_vblank_on. This merge
resolution has been tested in drm-intel-nightly for a while already.

This should be called by application level drivers before and
after mode setting, since on many devices the vertical blank
counter is reset at that time. Internally, the DRM snapshots
the last vblank count when the ioctl is called with the
_DRM_PRE_MODESET command, so that the counter won't go backwards
(which is dealt with when _DRM_POST_MODESET is used).
This was only used for user-mode-settind drivers around
modesetting changes to allow the kernel to update the vblank
interrupt after mode setting, since on many devices the vertical
blank counter is reset to 0 at some point during modeset. Modern
drivers should not call this any more since with kernel mode
setting it is a no-op.
