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.
