Wasn't this patch reverted in Linus's tree for causing a regression on
some platforms? If so I'm not sure we should pull this in as a
candidate for stable should we, or am I missing something?

Good catch. It was reverted in commit 4aa9fc2a435a ("Revert "mm,
memory_hotplug: initialize struct pages for the full memory
section"").

We ended up with efad4e475c31 ("mm, memory_hotplug:
is_mem_section_removable do not pass the end of a zone") instead (and
possibly others - this was just from looking for commit messages that
mentioned that reverted commit).

I got it wrong then. I'll fix it up and get efad4e475c31 in instead.
Thanks!
