powerpc: Convert old cpumask API into new one
Adapt new API. Almost change is trivial. Most important change is the below line because we plan to change task->cpus_allowed implementation. - ctx->cpus_allowed = current->cpus_allowed; Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
