From 318facbee05417fb432603a8309a10cdb942a87b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 6 Jun 2006 16:09:39 +0200 Subject: [PATCH] [PATCH] powerpc: implement pcibus_to_node and pcibus_to_cpumask On 64bit powerpc we can find out what node a pci bus hangs off, so implement the topology.h macros that export this information. For 32bit this seems a little more difficult, but I don't know of 32bit powerpc NUMA machines either, so let's leave it out for now.
