Subject[PATCH v2] ACPI processor: Fix a typo error in commit 99b725084
Date
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:
