Bug#535571: kernel unaligned access copy_to_user_state with IPSec

[ja nein <reg9009@yahoo.de>]

Hi Jonathan,

ok, it took a while, but finally I've tested wheezy with latest kernel 
(linux-image-3.1.0-1-sparc64-smp) and the error's gone. It seems that 
somewhere to 3.x kernel the error was fixed.

Regards,
Sebastian
