For the floppy driver it certainly is since it's so slow compared to the rest of the system that optimizing access to a single variable or two isn't going to make any real difference So let's just leave it to the compiler - it'll do a better job anyway. This patch does away with a few register keywords in the SuperH floppy driver.
