[S390] smp_call_function cleanup

Browse source

Introduce __smp_call_function_map which calls a function on all cpus
given with a cpumask_t. Use it to implement smp_call_function and
smp_call_function_on. Replace smp_ext_bitcall_others with smp_ext_bitcall
and a for_each_cpu_mask loop. Use a cpumask_t instead of an atomic_t for
cpu counting and print a warning if preempt is on in
__smp_call_function_map().
