[PATCH 0/6] Nouveau on ARM fixes
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.

[PATCH v5 0/4] drm: nouveau: memory coherency on ARM
It has been a couple of months since v4 - apologies for this. v4 has not
received many comments, but this version addresses them and makes a new
attempt at pushing the critical bit for GK20A and Nouveau on ARM in
general.
As a reminder, this series addresses the memory coherency issue that we
are seeing on ARM platforms. Contrary to x86 which invalidates the PCI
caches whenever a write is made by
