Hi all, The goal of the series is to give a chance to the architecture to validate VIRTIO device features. in this respin: I use the original idea from Connie for an optional arch_has_restricted_memory_access. I renamed the callback accordingly, added the definition of ARCH_HAS_RESTRICTED_MEMORY_ACCESS inside the VIRTIO Kconfig and the selection in the PROTECTED_VIRTUALIZATION_GUEST config
