[PATCH] PCI: pci_assign_unassigned_resources() on x86
 
- Add sanity check for io[port,mem]_resource in setup-bus.c. These
  resources look like "free" as they have no parents, but obviously
  we must not touch them.
- In i386.c:pci_allocate_bus_resources(), if a bridge resource cannot be
  allocated for some reason, then clear its flags. This prevents any child
  allocations in this range, so the setup-bus code will work with a clean
  resource sub-tree.
- i386.c:pcibios_enable_resources() doesn't enable bridges, as it checks
  only resources 0-5, which looks like a clear bug to me. I suspect it
  might break hotplug as well in some cases.
