Merge branch 'linux-4.3' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into...

Nothing too crazy here, a couple of regression fixes + runpm/fbcon
race fix.

* 'linux-4.3' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
  drm/nouveau/bios: fix OF loading
  drm/nouveau/fbcon: take runpm reference when userspace has an open fd
  drm/nouveau/nouveau: Disable AGP for SiS 761
  drm/nouveau/display: allow up to 16k width/height for fermi+
  drm/nouveau/bios: translate devinit pri/sec i2c bus to internal identifiers
