This is the first set of patches to make Nouveau work on Tegra. Those are only the obvious correctness fixes, a lot of optimization work remains to be done, but at least it's enough to get accel working and let the machine survive a piglit run.
A new BO flag is introduced to allow userspace to hint the kernel about possible optimizations.
