One change which I'm currently making is to use kmalloc_node() instead
of kmalloc() for the per-NUMA node, and I suspect *that* is going
to make a quite a lot of different on those systems where the ratio of
remote to local memory access times is larger (as I assume it probably
would be on really big systems).
