Pull memblock fix from Mike Rapoport:
 "A call to memblock_free() or memblock_phys_free() issued after
  memblock data is discarded will result in use after free in
  memblock_isolate_range().

  Avoid those issues by making sure that memblock_discard points
  memblock.reserved.regions back at the static buffer"
