Subject: [PATCH] cpumask: let num_*_cpus() function always return unsigned
 values

Dependent on CONFIG_SMP the num_*_cpus() functions return unsigned or
signed values.  Let them always return unsigned values to avoid strange
casts.

Fixes at least one warning:

 kernel/kprobes.c: In function 'register_kretprobe':
 kernel/kprobes.c:1038: warning: comparison of distinct pointer types lacks a cast
