No, it's not really about optimisation. In the case of this driver, my preference would be more directed to using common code (either in the form of these changes, or __builtin_parity) rather than any performance considerations. The implementation details I gave was more a note about the platforms that are applicable for the driver. Cheers, Jeremy
