This series fixes couple issues or improves its reliability:

  * The PDC event is never detected inside the IRQ handler in surprise
    hot-add path.
  * The slot's initial state should be REGISTERED state if it's emtpy.
    Otherwise, the PCI devices behind the slot won't be populated properly
    in hot-add path.
  * PDC isn't reliable for hot-add on some machines. Introduce another
    device-tree property to disable it if required by (skiboot) firmware.

Gavin Shan (3):
 drivers/pci/hotplug: Handle presence detection change properly
 drivers/pci/hotplug: Fix initial state for empty slot
 drivers/pci/hotplug: Mask PDC interrupt if required

Michael, could you help to take a look when you have available time?
I hope those 3 patches can be merged in next merge window, which seems
to come pretty soon.

Thanks,
Gavin
