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 entry.


Regards,
Pierre
