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. > Speeding up userland AES is very interesting to me for a couple of apps. If there is a proper way I should test on RELENG_9, please let me know as I am few boxes that I would be happy to test/deploy on. ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
