kick_all_cpus_sync - Force all cpus out of idle
Used to synchronize the update of pm_idle function pointer. It's called after the pointer is updated and returns after the dummy callback function has been executed on all cpus. The execution of the function can only happen on the remote cpus after they have left the idle function which had been called via pm_idle function pointer. So it's guaranteed that nothing uses the previous pointer anymore.

on_each_cpu_mask(): Run a function on processors specified by cpumask, which may include the local processor. : The set of cpus to run on (only runs on online subset). : The function to run. This must be fast and non-blocking. : An arbitrary pointer to pass to the function. : If true, wait (atomically) until function has completed on other CPUs.
If is true, then returns once has returned.
You must not call this function with disabled interrupts or from a hardware interrupt handler or from a bottom half handler.
