(Resending the patch set to include more arch maintainers.)

Change the pci_create_bus() interface to pass in available resources to get them
settled down early. This is to avoid possible resource conflicts while doing
pci_scan_slot() in pci_scan_child_bus(). Note that pcibios_fixup_bus() can get
rid of such conflicts, but it's done AFTER scanning slots.

In addition, MIPS PCI resources are now fixed using this new interface.

Jesse, I assume these are headed for the 3.2 merge window, right?

Do you have a git tree anywhere where we could check without having to
bother you?
