Having it available on Kconfig is indeed fine, but this still needs
some kind of configure checks AFAIK, as it's only available on Linux.
I'm certainly missing some context, but whether XEN_IGD_PASSTHROUGH
gets defined on Kconfig or not shouldn't really matter for this patch,
as we would still need to gate the code properly so it's not build
when PCI passthrough (or whatever name the option has) is not enabled?
Thanks, Roger.
