Thread-topic: [Xen-devel] [PATCH] Add cpu hotplug support for 2.6.32 branch
In .32 both the hotplug through container/processor will all go-through the 
acpi_bus_add =>acpi_processor_driver.add, so we only need change the .add 
function to achive the purpose.

After checking the code, I think in .31 kernel, the changes to the 
acpi_processor_hotplug_notify() code path is not needed.
