Hmmm... top_cpuset.cpus_allowed is filled using cpumask_setall(),
which may include more bits than cpu_possible_mask, which is kinda
weird.  We probably wanna initialize it with cpu_possible_mask and
also maybe using cpu_possible_mask in the above would be clearer?

Also, shouldn't this be dependent upon sane_behavior?

Thanks.
