It can still be > applied cleanly on top of linux-5.10.y. KVM opts out of the AUTOSEL logic and instead uses MANUALSEL. The basic idea is the same, use scripts/magic to determine what commits that _aren't_ tagged with an explicit "Cc: stable@vger.kernel.org" should be backported to stable trees, the difference being that MANUALSEL requires an explicit Acked-by from the maintainer. Many (most?) of the automatically selected patches for KVM are good stable candidates, but there are enough selected patches that we _don't_ want backported that the "apply unless there's an objection" model of AUTOSEL is a bit too risky for us.
