From c3dd1995620cdcd65cf4944c4164b0dbc16e557c Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Thu, 16 Nov 2023 06:22:43 -0800 Subject: [PATCH] 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.
