cpuidle: Use kick_all_cpus_sync()
kick_all_cpus_sync() is the core implementation of cpu_idle_wait() which is copied all over the arch code. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20120507175652.119842173@linutronix.de
