Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this. No code changes here whatsoever, aside from fixing up a couple of include file pathnames. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
