[RFC PATCH 5/8] nouveau: Add methods preparing for prime fencing

From: Maarten Lankhorst
Date: Tue Jul 10 2012 - 06:59:22 EST

From: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxx>

This can be used by nv84 and nvc0 to implement hardware fencing,
earlier systems will require more thought but can fall back to
software for now.
