Re: [RFC] padlock aes, unification of setkey()

[Stefan Hellermann <stefan@the2masters.de>]

Hello,

I'm got my Via Epia SN Board a few days ago and could test everything related to the
padlock engine, I'm especially interested in the aes-{lrw,xts} combo, this doesn't work at
the moment (last tested with 2.6.25-rc1).

Cheers,
Stefan
