The interrupt shadow created by STI or MOV-SS-like operations is part of

STI and MOV-SS interrupt shadow are both treated differently by
hardware. Any attempt to unify them into a single field is wrong,
especially so in a hardware virtualization context, where they are
actually represented by different fields in the undocumented but
nevertheless extant format that can be inferred from the hardware
virtualization context used by specific vendors.
