Gavin Shan 360aebd85a drivers/pci/hotplug: Support surprise hotplug in powernv driver ... This supports PCI surprise hotplug. The design is highlighted as below: * The PCI slot's surprise hotplug capability is exposed through device node property "ibm,slot-surprise-pluggable", meaning PCI surprise hotplug will be disabled if skiboot doesn't support it yet. * The interrupt because of presence or link state change is raised on surprise hotplug event. One event is allocated and queued to the PCI slot for workqueue to pick it up and process in serialized fashion. The code flow for surprise hotplug is same to that for managed hotplug except: the affected PEs are put into frozen state to avoid unexpected EEH error reporting in surprise hot remove path.
