OpenRISC was not an SMP architecture last I looked... did the relevant spec updates get made? If not, NAK.
The issue is, the OpenRISC architecture shouldn't be a moving target defined by what the kernel supports... there's a spec that the kernel conforms to. This is important for the (few) real users of the architecture.
