Can we make a simple default of 1 per node, which is what 99%
of people want, and then make it more complicated later if people
complain? It's really pretty easy:

for (node = 0; node < numnodes; ++node) {
        kswapd = kick_off_kswapd_for_node(node);
        kswapd->cpus_allowed = node_to_cpus(node);
}

Seems sane.
 

Or whatever the current cpus_allowed method is. All we seem to need
is node_to_cpus ... I can give that to you tommorow with no problem,
it's trivial.

Tomorrow sounds too early - it'd be nice to get some before-n-after
performance testing to go along with that patch ;)
