[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.
