I don't believe the module version is needed here. Otherwise I would
question the #if altogether. Which now I'm looking at it, why is it
needed?

What includes this header file that wouldn't have that set anyway? The
only place it is included is in:

 arch/x86/hyperv/mmu.c

Is that compiled without CONFIG_HYPERV?
