函数名称：MONITOR/MWAIT with no hints, used for default C1 state. This invokes MWAIT* with interrupts enabled and no flags, which is backwards compatible with the* original MWAIT implementation.

函数原型：static __cpuidle void mwait_idle(void)

返回类型：void

参数：无

805  如果非current_set_polling_and_test()则
806  trace_cpu_idle_rcuidle(1, 当前cpu ID())
807  如果this_cpu_has(AAI65, CLFLUSH required before MONITOR )则
808  Force strict CPU ordering.* And yes, this might be required on UP too when we're talking* to devices.()
809  clflush((void * ) & flags)
810  Force strict CPU ordering.* And yes, this might be required on UP too when we're talking* to devices.()
813  __monitor((void * ) & flags, 0, 0)
814  如果非need_resched()则__sti_mwait(0, 0)
816  否则开中断()
818  trace_cpu_idle_rcuidle(PWR_EVENT_EXIT, 当前cpu ID())
819  否则
820  开中断()
822  __current_clr_polling()
