I am not so sure about this.
vmfunc is reachable in the instruction emulator on hardware which
doesn't support vmfunc, and there is explicit provision for using vmfunc
0 via hypercall on hardware lacking vmfunc support.
Given that the #VE part of altp2m is always emulated architecturally, I
think there is an argument to be made for also emulating EPTP switching
architecturally as well.
