	  The main use of the event stream is wfe-based timeouts of userspace
	  locking implementations. It might also be useful for imposing timeout
	  on wfe to safeguard against any programming errors in case an expected
	  event is not generated.
	  This must be disabled for hardware validation purposes to detect any
