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.
David Daney (2): PCI: Allow PCI_DEV_FLAGS_NO_BUS_RESET to be used on bus device PCI: Avoid bus reset for Cavium cn8xxx root ports
Jan Glauber (1): PCI: Avoid slot reset for Cavium cn8xxx root ports
