3) the next CPU entry will call kvm_arch_put_registers:

         if (cpu->kvm_vcpu_dirty) {
             kvm_arch_put_registers(cpu, KVM_PUT_RUNTIME_STATE);
             cpu->kvm_vcpu_dirty = false;
         }


But, I don't set cpu->kvm_vcpu_dirty anywhere (?).
Yeah, the next CPU entry will *not* call kvm_arch_put_registers with your change. It will call it with vanilla cpu_synchronize_all_states().
