The end address of memory region section isn't correctly calculated
which leads to overflowed mtree dump:

  Dispatch
    Physical sections
      ......
      #70 @0000000000002000..0000000000011fff io [ROOT]
      #71 @0000000000005000..0000000000005fff (noname)
      #72 @0000000000005000..0000000000014fff io [ROOT]
      #73 @0000000000005658..0000000000005658 vmport
      #74 @0000000000005659..0000000000015658 io [ROOT]
      #75 @0000000000006000..0000000000015fff io [ROOT]

After fix:
      #70 @0000000000002000..0000000000004fff io [ROOT]
      #71 @0000000000005000..0000000000005fff (noname)
      #72 @0000000000005000..0000000000005657 io [ROOT]
      #73 @0000000000005658..0000000000005658 vmport
      #74 @0000000000005659..0000000000005fff io [ROOT]
      #75 @0000000000006000..000000000000ffff io [ROOT]
