Thanks for doing this - when this gets queued up for 4.19, I can then
resubmit my 4.14 series.

Daniel mentioned the CVE-2021-33200 fixes that were just added. If you add
them to this series, I'll add them to the 4.14 series as well. They should
be clean cherry-picks on top of this.

The failing selftest is a little odd - why would it need allowing bounded
loops to succeed if it was written before those were allowed? In any case,
it was already failing, so that shouldn't stop this series from being
applied.
