I think I caused the confusion here, as "this patch" refers to the
original fix which has been queued, rather than the patch to the
selftest, which I don't consider a candidate for backports.

"Someone" == we, the KVM/arm64 maintainers.

And that's on purpose. A selftest patch doesn't fix anything, and I
really don't want to use the "Fixes:" tag as a type of dependency.
Additionally, these tests are mostly pointless anyway, specially this
one, which really should be deleted.

Nothing, apart from applying the original fix, and blissfully ignoring
the selftest, unless someone really want to backport it (I don't).

Thanks, and sorry for the confusion.
