If we're going to change the way we print E820 ranges, I think
we should make them consistent with the way we handle %pR, e.g.,
use something like this:

"%s: [mem %#018Lx-%#018Lx]"

This is a little different because %pR wouldn't make the field
so wide, but when we discussed this earlier, keeping the table
alignment was thought to be important. That discussion starts
here: https://lkml.org/lkml/2010/9/22/248

Same comment applies to the update, remove, PCI gap (which
your patch currently doesn't touch), and EFI output.

I know this kind of derails the whole "remove characters" point
of your patch (and I support that in principle), but I do think
consistency is important, too. We have too many different ways
of printing the same information.
