Fix a call by tunables_write() to smp_processor_id() within a preemptable region. Call get_cpu()/put_cpu() around the region where the returned cpu number is actually used, which makes it non-preemptable. A DEBUG_PREEMPT warning is prevented. UV does not support cpu hotplug yet, but this is a step toward that ability as well.
