The quirk to irq_period unearthed an unrobustness we had in the hw_counter initialization sequence: we left irq_period at 0, which was then quirked up to 2 ... which then generated a _lot_ of interrupts during 'perf stat' runs, slowed them down and skewed the counter results in general. Initialize irq_period to the maximum instead.
