[PATCH] PPC32: Fix copy prefetch on non coherent PPCs

From: Matt Porter <mporter@kernel.crashing.org>

This patch fixes the condition where prefetching cache lines beyond a
buffer can cause data corruption on non cache coherent PPCs.  It is a port
of the version that went into 2.4.  From Eugene Surovegin
<ebs@ebshome.net>.
