Hi Gavin,

This applies cleanup on the cross call functions, no functional
changes are introduced:
   * Refactor CROSSCALL_INIT to use "do { ... } while (0)" to be
     compatible with scripts/checkpatch.pl
What does this mean?

   * Use smp_call_func_t for @fn argument in sdei_do_cross_call()
   * Remove unnecessary space before @event in sdei_do_cross_call()

Huh, I'm surprised I didn't write it like that the first time!

+static inline int sdei_do_cross_call(smp_call_func_t fn,
+				     struct sdei_event *event)
 {
 	struct sdei_crosscall_args arg;

With some kind of motivation for the change, instead of "checkpatch made me do it":
