Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Tue, 21 Dec 2010 16:08:47 -0800 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).
