Although the event of the uncore PMU can only be opened on a single CPU, some PMU does have the affinity on a range of CPUs. For example the L3C PMU is associated to the CPUs sharing the L3T it monitors. Users may infer this affinity by the PMU name which may have SCCL ID and CCL ID encoded (for L3C etc), but it's not that straightforward. So export this information by adding an "associated_cpus" sysfs attribute then user can get this directly.
