This is definitely a kernel bug.  Essentially, we're reporting out NUMA
information in cpuinfo when we should be reporting out information about
the CPU itself.  I'm working on an upstream kernel patch.  I have a
patch available for testing that I can attach to this bug, although I'm
unsure this particular version will be accepted upstream.
