powerpc/smp: More generic support for "soft hotplug" This adds more generic support for doing CPU hotplug with a simple idle loop and no actual reset of the processors. The generic smp_generic_kick_cpu() does the hotplug bringup trick if the PACA shows that the CPU has already been started at boot and we provide an accessor for the CPU state.
