Will it be as bad as the generic implementation which does it byte per 
byte ?

I don't have any 64 bits target, can someone test it using the test app 
I have added in selftests ?

Or should I just leave it as is for 64 bits and just do the 
implementation for 32 bits until someone wants to try and do it for PPC64 ?
