Hi all, The goal of the series is to give a chance to the architecture to validate VIRTIO device features. I changed VIRTIO_F_IOMMU_PLATFORM to VIRTIO_F_ACCESS_PLATFORM I forgot in drivers/virtio/Kconfig, and put back the inclusion of virtio_config.h for the definition of the callback in arch/s390/mm/init.c I wrongly removed in the last series. Regards, Pierre Pierre Morel (2): virtio: let

Hi all, The goal of the series is to give a chance to the architecture to validate VIRTIO device features. The tests are back to virtio_finalize_features. No more argument for the architecture callback which only reports if the architecture needs guest memory access restrictions for VIRTIO. I renamed the callback to arch_has_restricted_virtio_memory_access, the config option to
