Subject: [PATCH 14/27] sched, numa, mm, arch: Add variable locality exception
Date: Mon, 19 Nov 2012 03:14:31 +0100 [thread overview]
Message-ID: <1353291284-2998-15-git-send-email-mingo@kernel.org> (raw)
In-Reply-To: <1353291284-2998-1-git-send-email-mingo@kernel.org>
From: Peter Zijlstra <a.p.zijlstra@chello.nl>
Some architectures (ab)use NUMA to represent different memory
regions all cpu-local but of different latencies, such as SuperH.
The naming comes from Mel Gorman.
