The difference between for_each_cpu() and for_each_set_bit()
is that the latter uses cpumask_next() instead of find_next_bit(),
and so calls cpumask_check().
This check is useless because the iterator value is not provided by
user. It generates false-positives for the very last iteration
of for_each_cpu().
