The s390 kernel does not compile if virtio console is enabled, but guest
support is disabled:

  LD      .tmp_vmlinux1
arch/s390/kernel/built-in.o: In function `setup_arch':
/space/linux-2.5/arch/s390/kernel/setup.c:773: undefined reference to
`s390_virtio_console_init'

The fix is related to
commit 99e65c92f2bbf84f43766a8bf701e36817d62822

    KVM: s390: Fix guest kconfig

Which changed the build process to build kvm_virtio.c only if CONFIG_S390_GUEST
is set. We must ifdef the prototype in the header file accordingly.
