on_each_cpu() returns an int. For consistency reasons, would it make sense to
make on_each_cpu_maks() to return and int? I know that the difference is that
smp_call_function() returns and int and smp_call_function_many() returns void,
but to me it actually seems strange and either I'm missing something important
(which is likely) or this needs to get cleaned up at one point as well.
