Again and again, WHY? dev_t's have been 32 bit opaque values for the
longest time -- we just didn't use the top bits. There is no reason to
do this sort of thing. The *only* thing we need COMPAT_ for is to
instruct the kernel to honor old device numbers for a while. It is
true that an old mknod binary will lose on a new machine. "So what?"
