Cool stuff. On a related note, do we still want to keep the spu_acquire()/
spu_release() naming? It may be clearer to use mutex_lock_interruptible()
and a manual spu_deactivate() instead. The reason for which we originally
introduced separate functions has long disappeared, except for
spu_acquire_runnable, and we're about to get rid of that as well.
