It feels a little strange to see this here instead of an
implementation of stgi/clgi in x86_emulate. Any reason for not going
that route?
We already know the instruction is stgi, no need to go through the
guest page tables to fetch it. We do the same thing for all
instructions for which we have the length and all the information
necessary to execute it.
Fair enough.

GIF somehow needs exposure to userspace too, right? Otherwise, when
using -no-kernel-apic, userspace may try to inject an interrupt when
the guest cannot handle it, right?
Hmm, right, it needs to close the interrupt window.
