Very nice cleanups!

Magny-Cours indeed will need one more sched-domains level,
something like:

[smt thread]
internal numa node
cpu socket
external numa node

... which is certainly interesting, especially since the hierarchy
possibly 'crosses', i.e. we might have the two internal numa nodes
share a L2 or L3 cache, right?

I'd also not be surprised if the load-balancer needed some care to
properly handle such a setup.

It's all welcome work in any case, and for .32.
