What do you mean? What does VMPTRLD need to do with the launch status?
The VMCLEAR and VMLAUNCH/VMRESUME emulation need to clear and check the
emulated-VMX launch status (which we called vmcs12->launch_state), and indeed
they already do so (that code appears in other patches, not this specific one).
