Merge tag 'drm-intel-next-2014-05-23' of git://anongit.freedesktop.org/drm-intel into drm-next 

- prep refactoring for execlists (Oscar Mateo)
- 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)
- OOM handling improvements from Chris, with now have a neat oom notifier which
  jumps additional debug information.
- topdown allocation of ppgtt PDEs (Ben)
- fixes and small improvements all over

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.

* commands may hash to the same bucket due to not including opcode bits that
* make the command unique. For now, we will risk hashing to the same bucket.
*
* If we attempt to generate a perfect hash, we should be able to look at bits
