Subject: ACPI processor: Fix tick_broadcast_mask online/offline regression
From: Feng Tang <[email protected]>
commit b7db60f45d74497c723dc7ae1370cf0b37dfb0d8 upstream.
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:
