From 83b78bd2d31f12d7d9317d9802a1996a7bd8a6f2 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Wed, 6 Jul 2005 10:47:07 -0700 Subject: [PATCH] [PATCH] Fix broken kmalloc_node in rc1/rc2 This patch used to be in Andrew's tree before the NUMA slab allocator went in. Either this patch or the NUMA slab allocator is needed in order for kmalloc_node to work correctly. pcibus_to_node may be used to generate the node information passed to kmalloc_node. pcibus_to_node returns -1 if it was not able to determine on which node a pcibus is located. For that case kmalloc_node must work like kmalloc.
