Patch is correct and so I applied it. Not a big issue though. There is
only one system supported currently that supports a mix of different
processor types (IP27) and those are very similar so it doesn't cause
pain.

The patch is required on SMP systems as without it you get:
BUG: using smp_processor_id() in preemptible [00000000] code: cat/687
