PSW restart can be triggered on offline CPUs. If this happens, currently the PSW restart code fails, because functions like smp_processor_id() do not work on offline CPUs. This patch fixes this as follows: If PSW restart is triggered on an offline CPU, the PSW restart (sigp restart) is done a second time on another CPU that is online and the old CPU is stopped afterwards.
