Would you believe that this patch (which removes code) actually increases
drivers/scsi/ide-scsi.o .text by 75 bytes?
I didn't look to see why - probably that huge arg count is hurting,
possibly some additional strings being emitted?
Either way, perhaps a simple little front-end to print_hex_dump() is called
for.
