Impact: Qemu mach-virt requires VIRTIO_CONSOLE=y as is the only available console option there, and having it as =m doesn't lt you see the bootup messages until initrd is mounted
Fix: apply the attached config patch and recompile a kernel with it
Testcase:
try booting a qemu mach-virt instance with and without a patched kernel
