The virtio_ccw errors are caused by '[PATCH 6.1 033/167] s390/virtio_ccw: fix virtual vs physical address confusion' Picking the following 2 dependencies would resolve the build error: 1bcf7f48b7d4 s390/cio: use bitwise types to allow for type checking 8b19e145e82f s390/cio: introduce bitwise dma types and helper functions
