Subject: [PATCH] Fix broken kmalloc_node in rc1/rc2
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=83b78bd2d31f12d7d9317d9802a1996a7bd8a6f2;p=deliverable%2Flinux.git

[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.
