For whatever reason on ARM/arm64 machines kvmtool greets us with quite some elaborate messages: Info: Loaded kernel to 0x80080000 (18704896 bytes) Info: Placing fdt at 0x8fe00000 - 0x8fffffff Info: virtio-mmio.devices=0x200@0x10000:36 Info: virtio-mmio.devices=0x200@0x10200:37 Info: virtio-mmio.devices=0x200@0x10400:38 This is not really useful information for the casual user, so change those lines to use pr_debug(). This also fixes the long standing line ending issue for the mmio output.
