* smp_call_function(): Run a function on all other CPUs.
* @func: The function to run. This must be fast and non-blocking.

* @wait: If true, wait (atomically) until function has completed on other CPUs.
*
* Returns 0 on success, else a negative status code. Does not return until
* You must not call this function with disabled interrupts or from a
* hardware interrupt handler or from a bottom half handler.
