I didn't say that - I said "any code (proprietary included) can link to

And yet, I don't want to be on the receiving end of the complaints when
those do change. But that's beside the point.

So I think we're on the same page: I'll make everything using x86_hyper*
depend on CONFIG_HYPERVISOR_GUEST and all are happy.

Thanks.
