Yes, it seems that only HOTREMOVE needs MEMORY_ISOLATION but that should
be done in a separate patch as this change is already upstream and
should be merged separately. It would also be nice to mention which
functions are we talking about. AFAICS:
alloc_migrate_target, test_pages_isolated, start_isolate_page_range and
undo_isolate_page_range.
