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> Reviewed-by: Rafael J.

This function is then called in acpi_bus_driver_init. On failure, this function clears the field device->driver_data, but does not free its contents. Thus the free has to be done by the add function. In acpi_processor_add, the corresponding value is pr. This value is currently freed on failure before storing it in device->driver_data, but not after. This free is added in the error handling code at the end of the function. The per_cpu variable processors is also cleared so that it does not refer to a dangling pointer.
