Date: Wed, 1 Dec 2010 17:36:14 -0800 (PST) From: David Rientjes <rientjes@...gle.com> To: Ingo Molnar <mingo@...e.hu>, "H. Peter Anvin" <hpa@...or.com>, Thomas Gleixner <tglx@...utronix.de> cc: x86@...nel.org, linux-kernel@...r.kernel.org Subject: [patch 1/5] x86: 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).
