At the moment, intel_bts events get disabled from intel PMU's disable callback, which includes event scheduling transactions of said PMU, which have nothing to do with intel_bts events. We do want to keep intel_bts events off inside the PMI handler to avoid filling up their buffer too soon. This patch moves intel_bts enabling/disabling directly to the PMI handler.
