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.
-- Changes -- v2 - v1: o Merge [PATCH 1/3] to [PATCH 3/3], so now 2 patches in total. o Add more info to patch description. o Fix arch breaks in default resource setup discovered by Bjorn Helgaas.
