Merge branch 'drm-nouveau-fixes' of git://people.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes
This covers all known nouveau regressions at the moment, along with a fix to not steal the console on headless GPUs. * 'drm-nouveau-fixes' of git://people.freedesktop.org/git/nouveau/linux-2.6: drm/nouveau: headless mode by default if pci class != vga display drm/nouveau: resurrect headless mode since rework drm/nv50/fb: prevent oops on chipsets without compression tags drm/nouveau: allow creation of zero-sized mm drm/nouveau/i2c: fix typo when checking nvio i2c port validity drm/nouveau: silence modesetting spam on pre-gf8 chipsets
