But we need the module device table to allow module auto loading. --- drivers/thermal/intel_powerclamp.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/drivers/thermal/intel_powerclamp.c b/drivers/thermal/intel_powerclamp.c index f0bad48..c82b41f 100644 --- a/drivers/thermal/intel_powerclamp.c +++ b/drivers/thermal/intel_powerclamp.c @@ -694,9 +694,16 @@ static int powerclamp_set_cur_state(struct thermal_cooling_device *cdev, .set_cur_state = powerclamp_set_cur_state, }; +static const struct x86_cpu_id __initconst intel_powerclamp_ids[] = { + { X86_VENDOR_INTEL, X86_FAMILY_ANY, X86_MODEL_ANY, X86_FEATURE_MWAIT }, + {} +}; +MODULE_DEVICE_TABLE(x86cpu, intel_powerclamp_ids); + static int __init powerclamp_probe(void) { - if (!boot_cpu_has(X86_FEATURE_MWAIT)) { + + if (!x86_match_cpu(intel_powerclamp_ids)) { pr_err("CPU does not support MWAIT"); return -ENODEV; } -- 1.9.1
