Subject: [PATCH 2/3] arm,integrator: replace old cpumask functions with new one.
Date: Thu, 23 Jun 2011 17:30:26 +0900	[thread overview]
Message-ID: <4E02F9A2.4040204@jp.fujitsu.com> (raw)
In-Reply-To: <4E02F92C.7070203@jp.fujitsu.com>

We plant to change task->cpus_allowed implementation in future.
Therefore this patch replace it with tsk_cpus_allowed() helper
macro.
