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..
