  Canonical kernel team - please apply 1bc74f1ccd457832dc515fc1febe6655985fdcd2 from the powerpc-fixes tree.

  https://git.kernel.org/cgit/linux/kernel/git/powerpc/linux.git/commit/?h=fixes&id=1bc74f1ccd457832dc515fc1febe6655985fdcd2

  powerpc/powernv: Fix stale PE primary bus
  When PCI bus is unplugged during full hotplug for EEH recovery,
  the platform PE instance (struct pnv_ioda_pe) isn't released and
  it dereferences the stale PCI bus that has been released. It leads
  to kernel crash when referring to the stale PCI bus.

  This fixes the issue by correcting the PE's primary bus when it's
  oneline at plugging time, in pnv_pci_dma_bus_setup() which is to
  be called by pcibios_fixup_bus().
