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

This patch series introduces a backend for kvm to run on IBM System z machines that uses the mainframe's sie virtualization capability. This work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with a 64bit linux host. Userspace will follow once we're done brushing it over. The patch queue consists of the following patches, which can be applied in sequence on top of kvm.git
