Sorry I've been trying to test this, but we had a network outage and then a
power outage .. it's been one of those weeks :)
With this applied on 3.16.7 I see the same arch as I do on mainline, which I
think is sufficient proof that it's working:
type=SYSCALL msg=audit(1423462405.202:23): arch=c0000015 syscall=39 success=yes ...
^
= 0x80000000 | 0x40000000 | 0x15
= 64bit | LE | EM_PPC64
So if you like you can add:
