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).
