[PATCH] numa_maps: Fix potential crash on non IA64 platforms

numa_maps should not scan over huge vmas in order not to cause problems for
non IA64 platforms that may have pte entries pointing to huge pages in a
variety of ways in their page tables.  Add a simple check to ignore vmas
containing huge pages.
