Description:	Discover cpuidle policy and mechanism



		Various CPUs today support multiple idle levels that are

		differentiated by varying exit latencies and power

		consumption during idle.



		Idle policy (governor) is differentiated from idle mechanism

		(driver)



		current_driver: displays current idle mechanism



		current_governor_ro: displays current idle policy



		See files in Documentation/cpuidle/ for more information.
