Log message:
For AMD SEV-ES use GUEST_INTERRUPT_MASK in vmm(4).
Due to state encryption vmm(4) cannot determine the state of the
interrupt enable flag from the rflags register of the guest.
Therefore the VMCB provides at offset 0x68 bit 1 the current state
of this flag. However, use the SMV_GUEST_INTR_MASK bit only if
this is a SEV-ES enabled guest. Otherwise, use the regular FLAGS
register.
