Well, as the patch is only slightly related to my original one I thought 
it is better to start a new patch as I had to change the subject also. 
The only relation between them would be the reference in the mail 
header. Maybe Wolfgang can bring some light into this situation.

What would be the right way to post this patch? And what would be the 
right way to post a patch doing exactly the same to the ARM optimized 
version of memcpy?

Sorry for all that administrative questions.

Regards,
Matthias
