In acpi_processor_add(), get_cpu_device() will return NULL sometimes, although the chances are small, I think it should be fixed.

This patch isn't necessary any more after the changes queued up for 3.11 in the acpi-hotplug branch of the linux-pm.git tree.
Ok, I noticed your patch set, just drop my patch.
But shouldn't this go to stable at least? I checked linux-3.9.4 and it applies fine. Whether this is relevant for other stable series I will leave up to somebody else. ;) Martin
Thanks Hanjun
Thanks, Rafael
