Subject: [PATCH 0/2] oom rework: high order enahncements

The first two patches are cleanups for the compaction and the second
patch is updated as per Vlastimil's feedback. I didn't add his Acked-by
because I have added COMPACT_SHOULD_RETRY to make the retry logic in
the page allocator more robust for future changes.

Hugh has still reported this is not sufficient but I would prefer to
handle the issue he is seeing in a separate patch once we understand
what is going on there. The second patch sounds like a reasonable
starting point to me.
