Subject: [PATCH 0/2] PageWaiters again

I cleaned up the changelog a bit and made a few tweaks to patch 1 as
described in my reply to Hugh. Resending with SOBs.

Thanks,
Nick

  mm: Use owner_priv bit for PageSwapCache, valid when PageSwapBacked
  mm: add PageWaiters indicating tasks are waiting for a page bit
