This is a backport of LBR virtualization fixes that recently landed in Linus's tree to 6.12.y.
Patch 1 is not a backport, it's introducing a helper that exists in Linus's tree to make the following backports more straightforward to apply.
Why not include the actual commit that adds that helper?
It was introduced as part of a much larger commit, 160f143cc131 ("KVM: SVM: Manually recalc all MSR intercepts on userspace MSR filter change"), which was a part of a 30+ patch series. The effort and risk to backport all of that for the helper is not justifiable.
Patch 2 should already be in queue-6.12, but it's included here as the remaining patches depend on it.
So this series will not apply?
It applies on 6.12.y today, but if it gets merged to 6.12.y first [1], then we may need to drop patch 2 from the to apply. There's a change that git drops it though because it should be identical ot the patch [1].
