Now, looking at it in the stable/9 context, I can see that pjd did not merge (as he said at the time of commit) r226839 & r226839. Is there any objection to merge these two (and possibly 247061 as well -- copyright update)? I ask that for two reasons, these two revisions are speeding up AES-NI quite a bit and they are required for using jmg's patch. I'll be testing all this in the next few days on my new AES-NI enabled machine. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto_at_keltia.net In memoriam to Ondine, our 2nd child: http://ondine.keltia.net/Received on Fri Aug 23 2013 - 13:16:22 UTC
