Performance will probably be bad on K7 Athlons - those have a microcoded movnti which is quite slow. Also BTW I don't see any code anywhere that tests the CPUID bits, so your code will fail spectacularly on a PII that didn't do SSE (intel user copy used to be enabled on those) One way to solve this might be to use different code using alternative() -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
