drm/nouveau: Simplify tile region handling. Instead of emptying the caches to avoid a race with the PFIFO puller, go straight ahead and try to recover from it when it happens. Also, kill pfifo->cache_flush and tile->lock, we don't need them anymore. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
