Message-Id: <20110429001547.3D6C.A69D9226@jp.fujitsu.com>
Date: Fri, 29 Apr 2011 00:14:08 +0900 (JST)
From: KOSAKI Motohiro <kosaki.motohiro@...fujitsu.com>

Subject: [PATCH] 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.
