Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
This is a major rework of the nouveau driver core, to reflect more closely
how the hw is used and to make it easier to implement newer features now
that the GPUs are more clearly understood than when nouveau started.
It also contains a few other bits:
thermal patches
nv41/44 pcie gart fixes
i2c unregistering fixes.
