Using vfio-pci on a combination of cn8xxx and some PCI devices results in a kernel panic. This is triggered by issuing a bus or a slot reset on the PCI device. The solution is to prevent the reset. I've dropped the vfio patch from the previous series as vfio-pci already checks in the reset path for pci_bus_resetable() and pci_slot_resetable(). With this series both checks indicate that the reset is not possible preventing the kernel panic.
