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 -- v3 - v2: o Do not do fixups for root buses in pcibios_fixup_bus(). o Skip bus creation when bus resources cannot be allocated. o PCI domain/bus numbers added to the error info in controller_resources(). 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.
