	199	This option enables support for event stream generation based on
	200	the ARM architected timer. It is used for waking up CPUs executing
	201	the wfe instruction at a frequency represented as a power-of-2
	202	divisor of the clock rate.
	203	The main use of the event stream is wfe-based timeouts of userspace
	204	locking implementations. It might also be useful for imposing timeout
	205	on wfe to safeguard against any programming errors in case an expected
	206	event is not generated.
	207	This must be disabled for hardware validation purposes to detect any
	208	hardware anomalies of missing events.
