Careful. That one had a bug too, and we have 891cb2a72d82 ("mm,
memory_hotplug: fix off-by-one in is_pageblock_removable").

All of these were *horribly* and subtly buggy, and might be
intertwined with other issues. And only trigger on a few specific
machines where the memory map layout is just right to trigger some
special case or other, and you have just the right config.

It might be best to verify with Michal Hocko. Michal?
