It seems like an interface, similar to the one proposed by Ulrich, that
described the NUMA topology would have obsoleted numa_maps and you could
only rely on smaps to determine locality. There's existing userspace
dependencies on numa_maps already, though, so owell.

I had to fix numa_maps output when autonuma was merged for a much more
subtle difference at so I know some
people actually parse this and care quite a bit about its accuracy, it's a
shame it can't be deprecated in favor of adding the necessary information
to smaps.
