[PATCH v2 0/1] s390: virtio: let's arch choose to accept devices without IOMMU feature
An architecture protecting the guest memory against unauthorized host access may want to enforce VIRTIO I/O device protection through the use of VIRTIO_F_IOMMU_PLATFORM. Let's give a chance to the architecture to accept or not devices without VIRTIO_F_IOMMU_PLATFORM.
