      Make System.map and System.dump_map drastically more useful by adding:
      - the actual memory used per mapping (RSS)
      - the actual page size of the mapping
      - THP state (used, advised, eligible, forbidden)
      - the commit state
      - swap state

      Also, provide a summary for:
      - total RSS
      - total size of hugetlb memory
      - how much memory uses THPs
      - how much memory had been swapped out
      - how much memory was committed
