I've merged v10 of "Memory poison recovery in khugepaged collapsing" so
let's base on that please?

"Memory poison recovery in khugepaged collapsing" shows no sign of
review, which is worrisome for a series at version 10.  Hopefully
people will step up soon.  So there's presently a risk that "Memory
poison recovery in khugepaged collapsing" will go away again, so don't
lose the pre-rebase series :(
