What prevented it to be accepted into 5.10-stable? 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@xxxxxxxxxxxxxxx" should be backported to stable trees, the
difference being that MANUALSEL requires an explicit Acked-by from the maintainer.

But as far as I understand it was not applied, and neither was "KVM: x86: nSVM: deal with L1 hypervisor that intercepts interrupts but lets L2 control them".
