Before you add memory_map.nr_map, you should be able to iterate
from 0 to (not inclusive) nr. At least as far as I recall the original
patch.
Sorry, I really don't understand what you want.
Before we add memory_map.nr_map, e820[0, nr) don't include low/high
memory, right?
Why? memory_map is representing the reserved areas only, isn't it?

Am I wrong with your expectation?
Thanks

If that's not the case, then of course everything is fine.
