I don't want to give you more work than necessary.
If we can get it for utopic that'd be great...at least then we'd have
one formally released version of Ubuntu that supported it.

Looks like libnuma is not supported on arm. That complicates the

It looks like it is mainly disabled because it is in Debian, see
