Shaohua Li 6fb332fabd memory hotplug: exclude isolated page from pco page alloc ... Pages marked as isolated should not be allocated again. If such pages reside in pcp list, they can be allocated too, so there is a ping-pong memory offline frees some pages to pcp list and the pages get allocated and then memory offline frees them again, this loop will happen again and again. This should have no impact in normal code path, because in normal code path, pages in pcp list aren't isolated, and below loop will break in the first entry.
