Hi Vincent,
FYI, the error/warning was bisected to this commit, please ignore it if it's irrelevant.
tree: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched/core head: 97450eb909658573dcacc1063b06d3d08642c0c1 commit: d4dbc991714eefcbd8d54a3204bd77a0a52bd32d [26/27] sched/cpufreq: Rename arch_update_thermal_pressure() => arch_update_hw_pressure() config: arm64-randconfig-r132-20240425 (https://download.01.org/0day-ci/archive/20240425/202404250740.VhQQoD7N-lkp@intel.com/config) compiler: aarch64-linux-gcc (GCC) 13.2.0 reproduce: (https://download.01.org/0day-ci/archive/20240425/202404250740.VhQQoD7N-lkp@intel.com/reproduce)
