We could try to tighten the condition about enabling realloc auto. Not enabling realloc auto when above 64bit mmio is not there for root bus. So the system does not need to take "pci=realloc=off" to have working network as old kernel. First patch is preparing for bus address converting with bus instead of dev. After those two patches get into pci-next or linus-tree, I will send other patches about 64bit resource allocation.
