For the reference, previous discussion of the problem: https://lore.kernel.org/kvm/87zgg6sza8.fsf@redhat.com/
The patch to fix this: https://lore.kernel.org/kvm/20221004123956.188909-19-vkuznets@redhat.com/
is part of "KVM: x86: hyper-v: Fine-grained TLB flush + L2 TLB flush features" series (v11: https://lore.kernel.org/kvm/20221004123956.188909-1-vkuznets@redhat.com/) which I hope to see in 6.2 (fingers crossed!), however, it is unlikely to go to stable@ unless we know that there's a real problem to fix. I'll backport it then.
