On certain processors, the uncore PMU boxes may only be msr-bsed or PCI-based. But in both cases, the cpumask, suggesting on which CPUs to monitor to get full coverage of the particular PMU, must be created. However with the current code base, the cpumask was only created on processor which had at least one MSR-based uncore PMU. This patch removes that restriction and ensures the cpumask is created even when there is no msr-based PMU. For instance, on SNB client where only a PCI-based memory controller PMU is supported.
