Excuse me, I can't find these patches in:
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
git://git.kernel.org/pub/scm/linux/kernel/git/mhocko/mm.git
git://git.cmpxchg.org/linux-mmots.git

Could you point at the tree which I can rebase onto?
Should I cherry-pick Quentin's patches manually?

Best regards,
Alexander
