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.

Most of these patches are to reduce that divergence to reduce the risk of future bugs. Some cpuidle updates, mostly for non-Intel More will be coming, as they depend on this part.

When a cpu is set online, the acpi code call the intel idle init function. Unfortunately this code introduce a dependency between intel_idle and acpi. This patch is intended to remove this dependency by using the notifier of intel_idle. This patch has the benefit of encapsulating the intel_idle driver and remove some exported functions.

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.
