Subject: [PATCH] metag: Inhibit NUMA balancing.
Date: Mon, 4 Mar 2013 10:12:35 +0900 [thread overview]
Message-ID: <20130304011231.GA26475@linux-sh.org> (raw)
The metag NUMA implementation follows the SH model, using different nodes for
memories with different latencies. As such, we ensure that automated balancing
between nodes is inhibited, by way of the new ARCH_WANT_VARIABLE_LOCALITY.

Some Meta systems have MMU-mappable on-chip memories with
lower latencies than main memory. This enables support for
