Rather an having every pmu that needs a function that just returns 0 for
.event_idx define their own copy, reuse the one in kernel/events/core.c.

Rename from perf_swevent_event_idx() because we're no longer using it
for just software events. Naming is based on the perf_pmu_nop_*()
functions.

You could just use perf_pmu_nop_int() directly.

No, .event_idx needs something that takes a (struct perf_event *), 
perf_pmu_nop_int() takes a (struct pmu *).

Yeah, duh.

cheers
