commit: 17d9af0e32bdc4f263e23daefea699ed463bb87c [83/362] mm, compaction: simplify deferred compaction
config: x86_64-allnoconfig (attached as .config)
reproduce:
  git checkout 17d9af0e32bdc4f263e23daefea699ed463bb87c
  # save the attached .config to linux build tree
  make ARCH=x86_64 

Note: the balancenuma/mm-numa-protnone-v3r3 HEAD e5d6f2e502e06020eeb0f852a5ed853802799eb3 builds fine.
      It only hurts bisectibility.
