sparc: convert old cpumask API into new one
Adapt new API. Almost change is trivial, most important change are to remove following like =operator. cpumask_t cpu_mask = *mm_cpumask(mm); cpus_allowed = current->cpus_allowed; Because cpumask_var_t is =operator unsafe. These usage might prevent kernel core improvement. No functional change. Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
