Yes, true.

The reserve_ebda_region() has probably been like that for a while;
do you understand why it would be a problem conflicting with the
EFI memmap only now?

My other two concerns remain as well:

 2) Is what amounts to a change from calling reserve_bootmem()
    to calling reserve_early(), at the end of reserve_ebda_region()
    in the 32 bit case (now that it is merged with the 64 bit code)
    understood to be a desired and correct change?

 3) There has been quite a few patches restructuring this early
    memory reservation code over the last week.  What is the
    state of that work ... is it still "in progress" or is it
    thought to be complete?
