Subject: [S390] smp_call_function/smp_call_function_on locking.

[S390] smp_call_function/smp_call_function_on locking.

smp_call_function and smp_call_function_on share the same lock and
smp_call_function_on disables softirq's so it can be called from
softirq context as well. Hence smp_call_function muss disable
softirqs as well to avoid deadlocks.
