Well, core_siblings and cpu_node_sibling will only be different on
Magny-Cours anyway. So even if core_siblings becomes "all cores in
cpu_node" instead of "all cores in socket", it won't actually break any
existing setup. I personally prefer having the same kind of semantics
for all foo_siblings rather than having something with a different
meaning between core and thread.
