Just for the record, couple of points:

- as we will be expanding the PSCI operations with cpu_suspend, it makes
  more sense to decouple it from SMP and rename smp_operations to
  cpu_operations (or something else without 'smp').
- migrate_irqs() is pretty generic. You can look at arm and other
  architectures and maybe (later) move the code somewhere in
  kernel/irq/.

Otherwise the patches look good.

Thanks.
