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)? You repeated r226839 twice. What is the correct second revision? And both the ones above are just copyright updates, no functionality changes... > 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. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."Received on Fri Aug 23 2013 - 16:04:14 UTC
