struct acpi_processor_cx *cx
185  cpu = smp_processor_id()
188  percpu_entry = per_cpu_ptr(per CPU ptr , cpu)
189  This uses new MONITOR/MWAIT instructions on P4 processors with PNI,* which can obviate IPI to trigger checking of need_resched.* We execute MONITOR against need_resched and enter optimized wait state* through MWAIT
