It looks mostly good. I wouldn't use the high bit to differentiate the 64-bit operations, though. Since we do not allow to apply it to all operations the only effect will be that the compiler has a harder time generating the code for the switch statement. If you use continuous values a simple jump table can be used and no conditionals. Smaller and faster. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
