[PATCH v2 0/1] s390: virtio: let's arch choose to accept devices without IOMMU feature
From: Pierre Morel
Date:  Mon Jun 15 2020 - 08:39:37 EST
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.
