[PATCH 0/4] PCI: allocate pci bus num range for unassigned bridge busn

[Yinghai Lu <yinghai@kernel.org>]

5cb2147: PCI: Seperate child bus scanning to two passes overall
0cfebdb: PCI: kill pci_fixup_parent_subordinate_busnr()
cd03e86: PCI: Allocate bus range instead of use max blindly
e3edd5b: PCI: Add iobusn_resource and insert root bus range to that tree.

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.

Thanks
