Subject: x86/smp: Export symbol cpu_clustergroup_mask()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c3dd1995620cdcd65cf4944c4164b0dbc16e557c;p=linux.git

x86/smp: Export symbol cpu_clustergroup_mask()

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.
