For those cases we want it enabled. What *what* gets compiled ? You know our Makefile, it's crap :-) We enable built-in things when CONFIG_KVM=m (which means you cannot take a kernel build with CONFIG_KVM not set, enable CONFIG_KVM=m, and just build the module, it won't work). We could use KVM_BOOK3S_64 maybe ? > > I am trying to imagine a configuration where we really do not want > > IOMMU_API.

That's pretty much what the Makefile tells > you too :). Not really no. But that would do. You could have give a more useful answer in the first place though rather than stringing him along.
