If anyone has any objections, please let me know. ------------------ From: Antonio Borneo [ Upstream commit 1feb0377b9b816f89a04fc381eb19fc6bac9f4a4 ] When changes [1] and [2] have been applied to the driver etm4x, the same modifications have been also collapsed in [3] and applied in one shot to the driver etm3x. While doing this, the driver etm3x has not been aligned to etm4x on the use of non cpuslocked version of cpuhp callback setup APIs. The current code triggers two run-time warnings when the kernel is compiled with CONFIG_PROVE_LOCKING=y. Use non cpuslocked version of cpuhp callback setup APIs in driver etm3x, aligning it to the driver etm4x. [1] commit 2d1a8bfb61ec ("coresight: etm4x: Fix etm4_count race by moving cpuhp callbacks to init") [2] commit 22a550a306ad ("coresight: etm4x: Allow etm4x to be built as a module") [3] commit 97fe626ce64c ("coresight: etm3x: Allow etm3x to be built as a module") Fixes: 97fe626ce64c ("coresight: etm3x: Allow etm3x to be built as a module") Signed-off-by: Antonio Borneo Signed-off-by: Suzuki K Poulose Link: https://lore.kernel.org/r/20260108152427.357379-1-antonio.borneo@foss.st.com Signed-off-by: Sasha Levin --- drivers/hwtracing/coresight/coresight-etm3x-core.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/drivers/hwtracing/coresight/coresight-etm3x-core.c b/drivers/hwtracing/coresight/coresight-etm3x-core.c index a5e809589d3e3..0c011b7041696 100644 --- a/drivers/hwtracing/coresight/coresight-etm3x-core.c +++ b/drivers/hwtracing/coresight/coresight-etm3x-core.c @@ -795,16 +795,16 @@ static int __init etm_hp_setup(void) { int ret; - ret = cpuhp_setup_state_nocalls_cpuslocked(CPUHP_AP_ARM_CORESIGHT_STARTING, - "arm/coresight:starting", - etm_starting_cpu, etm_dying_cpu); + ret = cpuhp_setup_state_nocalls(CPUHP_AP_ARM_CORESIGHT_STARTING, + "arm/coresight:starting", + etm_starting_cpu, etm_dying_cpu); if (ret) return ret; - ret = cpuhp_setup_state_nocalls_cpuslocked(CPUHP_AP_ONLINE_DYN, - "arm/coresight:online", - etm_online_cpu, NULL); + ret = cpuhp_setup_state_nocalls(CPUHP_AP_ONLINE_DYN, + "arm/coresight:online", + etm_online_cpu, NULL); /* HP dyn state ID returned in ret on success */ if (ret > 0) { -- 2.51.0
