Unfortunately, this results in a conflict with mainline since the arm64 -next branches are based on -rc3 and there was a fix merged after that (feee6b298916 ("mm/memory_hotplug: shrink zones when offlining memory")) which changes the type of __remove_pages(). So I think I'll leave this for 5.7. Will
