I choose dump level 32 for free page filtering looking up mem_map
array. But I don't mean this is the final version now, I mean
experimental use for RFC, only. I prefer the setting that this logic
looking up mem_map array is automatically used if dump level 16 and
--cyclic option are specified at the same time.
