Well, it probably boots because it doesn't really seem to _change_ much of 
anything.

Things like this:

	-static inline void arch_send_call_function_ipi(cpumask_t mask)
	+static inline void arch_send_call_function_ipi(cpumask_t *mask)
	 {
	-       smp_ops.send_call_func_ipi(mask);
	+       smp_ops.send_call_func_ipi(*mask);
	 }

will still do that stack allocation at the time of the call. You'd have to 
pass the thing all the way down as a pointer..
