[PATCH] sparc: convert old cpumask API into new one
From: KOSAKI Motohiro
Date: Thu Apr 28 2011 - 11:14:19 EST
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.
