Chris Wilson 54895010a8 drm/i915: Add an rcu_barrier option to i915_drop_caches 
Sometimes a test has to wait for RCU to complete a grace period and
perform its callbacks, for example waiting for a close(fd) to actually
perform the fput(filp) and so trigger all the callbacks such as closing
GEM contexts. There is no trivial means of triggering an RCU barrier
from userspace, so add one for our convenience in
debugfs/i915_drop_caches
