ACPI processor: Fix tick_broadcast_mask online/offline regression
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, fixing the tick_broadcast_mask regression: https://lkml.org/lkml/2012/7/30/169 Signed-off-by: Feng Tang <feng.tang@intel.com> Cc: Thomas Renninger <trenn@suse.de> Cc: <stable@vger.kernel.org> # 3.3+ Reviewed-by: Rafael J.
