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.
could be found at: git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-busn-alloc
Thanks
Yinghai
