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.
