For the page allocator, __GFP_NORETRY implies that no OOM should be triggered, whereas memcg has an explicit parameter to disable OOM. The only callsites that want OOM disabled are THP charges and charge moving. THP already uses __GFP_NORETRY and charge moving can use it as well - one full reclaim cycle should be plenty. Switch it over, then remove the OOM parameter.
