We might still double-initialize PFNs when two zones overlap within a section, correct?
You mean that a section crosses zones boundary? I don't think it's that important.
What if there was a memory allocation in between that could allocate the once-initialized page?
Maybe it can't happen, or is not an issue for some other reason, but this code has been fragile and had a ton of subtle issues, so maybe worth documenting (or explaining here why it's just not relevant)
