I posted this patch for the first time about 3/4 year ago. The first
response has been the same. Please have a look at
My first posting:
http://marc.theaimsgroup.com/?l=linux-kernel&m=106321924724484&w=2
My original claim:
http://www.kerneli.org/pipermail/cryptoapi-devel/2003-August/000607.html
Jari Ruusu's posting:
http://marc.theaimsgroup.com/?l=linux-kernel&m=106321682117697&w=2
I suspect the result to be similar for a P4 for example. I could do some P4

Ack. I'll try to get his opinion on this.
