Next time please tell the x86 maintainers too ;-)

The thing that was blocking this commit is really the insufficient
sched-domains integration of said NUMA bits. I think the NUMA bits
look good and if the EDAC tree makes use of it we can merge it in
.32.

Mind preparing a separate branch for it (.31-rc5 based) and send me
a pull request so that we can share the commit between the EDAC tree
and the x86 tree?

Thanks,

Ingo
