Subject: [PATCH 0/2] respin of PageWaiters patch

Seeing as Mel said he would test it (and maybe Dave could as well), I
will post my patches again. There was a couple of page flags bugs pointed
out last time, which should be fixed.

Thanks,
Nick

  mm: Use owner_priv bit for PageSwapCache, valid when PageSwapBacked
  mm: add PageWaiters bit to indicate waitqueue should be checked
