Zwane Mwaikambo 7d5f9c0f10 [IA64] reduce cacheline bouncing in cpu_idle_wait ... Andi noted that during normal runtime cpu_idle_map is bounced around a lot, and occassionally at a higher frequency than the timer interrupt wakeup which we normally exit pm_idle from. So switch to a percpu variable. I didn't move things to the slow path because it would involve adding scheduler code to wakeup the idle thread on the cpus we're waiting for.
