Oh, right, I got confused w/ u64.

Hmm... looking at the boot log, not really. [ ) ranges are more
common. memblock code is one of notable exceptions and I actually was
thinking about converting it. [ ) ranges are easier to recognize and
most of code we have can't deal with the full range (and it shouldn't
need to - chopping off one top and bottom is much saner approach
anyway).
Thanks.
