[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.
