[PATCH 0/2] PCI: Don't enable realloc automatically when above 4g 64bit mmio is not supported

[Yinghai Lu <yinghai@kernel.org>]

On one system (Dell) realloc auto cause ixgbe does not work,
the system does not have enough range for sriov and rom.

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.

Thanks

Yinghai
