From 8c5a09082f4e61a176382e96a831a0636b918602 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Thu, 23 Jun 2005 00:08:18 -0700 Subject: [PATCH] x86/x86_64: pcibus_to_node Define pcibus_to_node to be able to figure out which NUMA node contains a given PCI device. This defines pcibus_to_node(bus) in include/linux/topology.h and adjusts the macros for i386 and x86_64 that already provided a way to determine the cpumask of a pci device. x86_64 was changed to not build an array of cpumasks anymore. Instead an array of nodes is build which can be used to generate the cpumask via node_to_cpumask.
