that works as well and produces the same debug output.

Important line of diff -u max_numnodes broken:

- memory size = 0x00000000b0000000 reserved size = 0x0000000004d1a360
+ memory size = 0x00000000b0000000 reserved size = 0x0000000004d12360

- reserved.cnt = 0xe
+ reserved.cnt = 0xd

- reserved[0xd] [0x000000035bff8000-0x000000035bffffff], 0x0000000000008000 bytes flags: 0x0

I have no idea which reservation this is, but it's not from one of the node data.
