Michael, here are two virtio/s390 patches for 4.8. First, Jing Liu noticed that she could trigger panics while playing around with hvc0 as preferred console but no virtio console: This can be fixed by not discarding our early_put_chars after init (as the minimal fix). This made us wonder why we still have that code around when no current host code supports the old transport: We have no idea

Hi all, The goal of the series is to give a chance to the architecture to validate VIRTIO device features. in this respin: 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, and the config

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
