It does not make much sense to have KVM in book3s-64bit and not to have IOMMU bits for PCI pass through support as it costs little and allows VFIO to function on book3s-kvm. Having IOMMU_API enabled will make it unnecessary to have a lot of IOMMU_API enabled, those files only accelerate user space emulated devices which do not seem to be in use very often.
