Wolfgang asked me that I add the numbers to the commit message. For the 
changelog I will investigate the git commands on how to do that best 
without manually editing the patch file before git send-email them.

Wolfgang didn't object on these names. If we use the OPTIMAL form it is 
still not clear what optimal mean. There may be a size optimized version 
and a speed optimized version. So we would need 
CONFIG_USE_ARCH_SPEED_OPTIMAL_MEMxxx which I personally dislike a lot as 
it is quite long. I also think that if there is an architecture specific 
function that it should be clear that this is optimal in some way.

Thanks for review
