Guess what, you broke powerpc again!

olof@...d:~/work/linux/k.org $ git grep devices_subsys
arch/powerpc/kernel/vio.c:extern struct kset devices_subsys; /* needed for vio_find_name() */
arch/powerpc/kernel/vio.c:      found = kset_find_obj(&devices_subsys, kobj_name);

Obviously causes build failues, even of ppc64_defconfig.

(I can unfortunately not boot test, since I lack hardware that uses vio)
