Merge branch 'linux-4.1' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes

Regression fix for Fermi acceleration, and fixes important to bringing
up display-less Maxwell boards.

* 'linux-4.1' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
  drm/nouveau/gr/gm204: remove a stray printk
  drm/nouveau/devinit/gm100-: force devinit table execution on boards without PDISP
  drm/nouveau/devinit/gf100: make the force-post condition more obvious
  drm/nouveau/gr/gf100-: fix wrong constant definition
