Patch 1 is meant to be squashed into the following patch in mmotm: mm-compaction-more-reliably-increase-direct-compaction-priority.patch Patch 2 is a cleanup for consistency. Patches 3 and 4 deal with the last (hopefully) remaining heuristic in the reclaim/compaction-vs-OOM scenario, which is the fragmentation index.
