There is a dependency of numa_alloc_distance() on
numa_nodemask_from_meminfo() that relies on numa_memblk but I agree that
they are not really related.

However, I'd prefer to keep this code in mm/numa_memblks.c because
node_distance() definitions and related code are different between
architecures and having this code outside numa_memblks in e.g
mm/numa.c would be way more involved.
