memblock/memory only shows ranges put in "memory".
memblock/reserved shows ranges put in "reserved".

If we just put them in "reserved", it will not displayed in "memory".

I guess those ranges are only put into "reserved"? Have those ranges put in
"memory"? Would you mind point the code where those messages are printed?
