    Subject[PATCH -v2 00/36] PCI: pci_host_bridge related cleanup and busn_alloc
    The first 13 patches are hostbridge clean up.
    will add struct device dev into host_bridge struct.
    also will add release support to make sure allocated resource get
    freed during root bus removal including hostbridge and pci_sysdata.

    others 23 patches are busn_alloc related.
    Set up iobusn_resource tree, and register bus number range to it.
    Later when need to find bus range, will try to allocate from the tree
    Need to test on arches other than x86. esp for ia64 and powerpc that support
    more than on peer root buses.

    The patches need to apply to pci/for-linus and pci/linux-next
    because one patch that is needed only is only in pci/for-linus

    could get from
    git:// for-pci-next

    please put them into pci/linux-next branch for more testing.

    -v2: dropped the patch that is with x86 pcibios_bus_to_resource that Bjorn objected.
    reorder the patchesset to mold one appended patch into previous patch.
