Message-Id: <20171212123448.953877836@linuxfoundation.org> Date: Tue, 12 Dec 2017 13:44:49 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Madhavan Srinivasan <maddy@...ux.vnet.ibm.com>, Michael Ellerman <mpe@...erman.id.au>, Sasha Levin <alexander.levin@...izon.com> Subject: [PATCH 4.14 109/164] powerpc/perf: Fix pmu_count to count only nest imc pmus 4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Madhavan Srinivasan <maddy@...ux.vnet.ibm.com> [ Upstream commit de34787f1096cce38e2590be0013b44418d14546 ] "pmu_count" in opal_imc_counters_probe() is intended to hold the number of successful nest imc pmu registerations. But current code also counts other imc units like core_imc and thread_imc. Patch add a check to count only nest imc pmus.
