It fixes an ARM regression in v4.0 that causes many boxes to crash on boot, including cns3xxx, dove, footbridge, iopl13xx, ip32x, iop33x, ixp4xx, ks8695, mv78xx0, orion5x, pxa, sa1100, etc. The change is in code that's only built for ARM and ARM64. Summary: Enumeration: Allow generic PCI domains without bridge "parent" pointer (Krzysztof Hałasa)" * tag 'pci-v4.5-fixes-5' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: PCI: Allow a NULL "parent" pointer in pci_bus_assign_domain_nr()
