[RFC PATCH 0/3] PCI: allocate pci bus num range for bridge scan

[Yinghai Lu <yinghai@kernel.org>]

2632ed3: PCI: kill pci_fixup_parent_subordinate_busnr()
5b951ec: PCI: Allocate bus range instead of use max blindly
b9459d8: PCI: Add iobusn_resource and insert root bus range to that tree.

set up iobusn_resource tree, and register bus number range it.
later when need to find bus range, will try to allocate from the tree

need to test on arches other than x86, to verify if root bus end finding
is right.
