Change smp_call_function_mask() callers to smp_call_function_many().
I chose to make on_each_cpu_mask() take a cpumask pointer; for the smallcpumasks on arm this is probably a slight pessimization, but it setsa good example for generic code which is being weaned off on-stackcpumasks.  I can simplify this patch further if you wish.
Compile-tested only.
