[PATCH v4 0/3] Workaround for bus/slot reset on Cavium cn8xxx root ports

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.

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 if bus reset is not possible
