Merge tag 'drm-intel-next-2014-02-14' of ssh://git.freedesktop.org/git/drm-intel into drm-next

- Fix the execbuf rebind performance regression due to topic/ppgtt (Chris).
- Fix up the connector cleanup ordering for sdvod i2c and dp aux devices (Imre).
- Try to preserve the firmware modeset config on driver load. And a bit of prep
  work for smooth takeover of the fb contents (Jesse).
- Prep cleanup for larger gtt address spaces on bdw (Ben).
- Improve our vblank_wait code to make hsw modesets faster (Paulo).
- Display debugfs file (Jesse).
- DRRS prep work from Vandana Kannan.
- pipestat interrupt handler to fix a few races around vblank/pageflip handling
  on byt (Imre).
- Improve display fuse handling for display-less SKUs (Damien).
- Drop locks while stalling for the gpu when serving pagefaults to improve
  interactivity (Chris).
- And as usual piles of other improvements and small fixes all over.
