Message-ID: <alpine.DEB.2.00.1003251618020.21038@chino.kir.corp.google.com> Date: Thu, 25 Mar 2010 16:19:06 -0700 (PDT) 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] x86: fix fake apicid to node mapping for numa emulation apicids must be mapped to the lowest node ids to maintain generic kernel use of functions such as cpu_to_node() that determine device affinity.
