[ ) ranges: e820, init_memory_mapping, NUMA nodes, Zone PFN ranges, PM
nosave memory

[ ] ranges: MTRR, NODE_DATA, early_node_map, [mm]io ranges

Hmm... I was only looking at the early boot messages which didn't
include the io ranges. It ultimately is a cosmetic issue so my
opinions aren't very strong but I think we can leave [mm]io ranges
alone and converge the rest into [ ) ranges sans the brackets?

Thanks.
