  [SRU][Artful] using vfio-pci on a combination of cn8xxx and some PCI
  devices results in a kernel panic.

  Fix Committed

Bug description:
  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 

  The following patches checks indicate that the reset is not possible
  preventing the kernel panic.
  357027786f35 PCI: Avoid bus reset if bridge itself is broken
  822155100e58 PCI: Mark Cavium CN8xxx to avoid bus reset
  33ba90aa4d44 PCI: Avoid slot reset if bridge itself is broken

  These patches are already in Bionic, we need these patches in Artful
  so that xenial linux-hwe also has the fix. The platforms of interest
  were certified with Xenial and linux-hwe, so we are interested in
  fixing this only in Artful.

  - Artful Host with Artful/bionic guests
  - Pass though PCI device (vfio-pci) from Artful to bionic and make sure its 
  - The device should pass through and not cause a kernel panic.

  A test kernel is available in ppa:manjo/lp1770254
