What is next:

handle c1e_idle() vs default_idle()
	run-time check for AMD workaround enable as part of default_idle?
give xen_arch_setup default_idle() w/o having it touch pm_idle
	perhaps it can simply set a flag to disable cpuidle...
		which is what would run if the xen kernel were
		booted on raw iron.  Or can we handle this
		at compile time?
delete pm_idle
	x86 will then use default_idle or cpuidle
allow cpuidle to use default_idle to handle the period
	where it polls because cpus have not yet registered
