This patch moves the percpu_pmu pointers into pmu_hw_events (which is itself allocated per cpu), which will allow for easier dynamic allocation. Both percpu and regular irqs are requested using percpu_pmu pointers as tokens, freeing us from having to know whether an irq is percpu within the handler, and thus avoiding a radix tree lookup on the handler path.
