Gah, that's actually breakage from b0a873ebbf8 (perf: Register PMU
implementations), which has the below fudge:


+static struct pmu pmu = {
+       .event_init     = sh_pmu_event_init,
+       .enable         = sh_pmu_enable,
+       .disable        = sh_pmu_disable,
+       .read           = sh_pmu_read,
+};
+
 static void sh_pmu_setup(int cpu)
-{
+
        struct cpu_hw_events *cpuhw = &per_cpu(cpu_hw_events, cpu);
 
        memset(cpuhw, 0, sizeof(struct cpu_hw_events));


Ingo, could you back-merge this?
