Regardless of this patch, you might want to update your global git config

Thanks for doing this, that addresses my main concerns, and is probably
small enough to still get it into 4.4 if Bjorn agrees with the general
idea of putting more function pointers into struct pci_host_bridge.
As a follow-on to this, we can now try to get rid of pcibios_align_resource
by moving the existing per-architecture implementations in there as well,
with a reasonable default for the common case.
