Hmm I just applied that series with b4 without local changes, on top of
kvm-x86/next at that time, which was kvm-x86-next-2025.09.30.

Maybe you had v2 or it was the patches that landed between
kvm-x86-next-2025.09.30 and the current tip of kvm-x86/next?

Yeah I can do that, although I think it wouldn't have helped in this
case as the same conflicts would apply. Perhaps mentioning that this is
based on kvm-x86-next-2025.09.30 would have helped?
