Hi Bjorn,
I tested these patches in IA_64, and use acpiphp driver to do the hot-plug test.
The hotplug action was triggered via sysfs interface(/sys/bus/pci/slots/xxx/).
The target pcie devices were fibre channel card and Intel 82576 card.As bellow:
0000:40:07.0 root port supports hotplug by acpiphp.
hot plug 0000:46:00.0 and its child devices and buses.
