In commit 99b725084 "ACPI processor hotplug: Delay acpi_processor_start() call for hotplugged cores", acpi_processor_hotplug(pr) was wrongly replaced by acpi_processor_cst_has_changed() inside the acpi_cpu_soft_notify(). This patch will restore it back, which also fixes a tick_broadcast_mask regression: https://lkml.org/lkml/2012/7/30/169 [Resend to ACPI mail list and Cc stable kernel] Signed-off-by: Feng Tang <feng.tang@xxxxxxxxx> Cc: Thomas Renninger <trenn@xxxxxxx> Cc: Deepthi Dharwar <deepthi@xxxxxxxxxxxxxxxxxx> Cc: <stable@xxxxxxxxxxxxxxx> # 3.3+ --- drivers/acpi/processor_driver.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/acpi/processor_driver.c b/drivers/acpi/processor_driver.c index ff8e04f..bfc31cb 100644 --- a/drivers/acpi/processor_driver.c +++ b/drivers/acpi/processor_driver.c @@ -437,7 +437,7 @@ static int acpi_cpu_soft_notify(struct notifier_block *nfb, /* Normal CPU soft online event */ } else { acpi_processor_ppc_has_changed(pr, 0); - acpi_processor_cst_has_changed(pr); + acpi_processor_hotplug(pr); acpi_processor_reevaluate_tstate(pr, action); acpi_processor_tstate_has_changed(pr); } -- 1.7.1 -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
