Subject: [PATCH 2/4] x86/smp: Export symbol cpu_clustergroup_mask

From: Kan Liang <kan.liang@...ux.intel.com>

Intel cstate PMU driver will invoke the topology_cluster_cpumask() to
retrieve the CPU mask of a cluster. A modpost error is triggered since
the symbol cpu_clustergroup_mask is not exported.
