Subject: [PATCH] ieee1394: first minimal NUMA awareness

Association of a host device with a node on NUMA machines optimizes
allocations of skbs given from the networking stack to eth1394.

Signed-off-by: Stefan Richter <stefanr@...6.in-berlin.de>

Note, in Linux 2.6.20 and earlier and 2.6.23 and later, eth1394 calls
or will call SET_NETDEV_DEV(eth1394_netdev, &h->device).
