[PATCH v8 0/2] s390: virtio: let arch validate VIRTIO features
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
