From: David Rientjes Date: Thu, 23 Dec 2010 01:23:40 +0000 (-0800) Subject: x86, numa: Reduce minimum fake node size to 32M X-Git-Tag: v2.6.38-rc1~415^2~6^2~6 X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=34dc9e74968ef4b582c3815b0124d88a68dfabef x86, numa: Reduce minimum fake node size to 32M This patch changes the minimum fake node size from 64MB to 32MB so it is possible to test NUMA code at a greater scale on smaller machines (64 nodes on a 2G machine, 1024 nodes on 32G machine with CONFIG_NODES_SHIFT=10).
