[RFC PATCH 0/3] PCI: allocate pci bus num range for bridge scan
From: Yinghai Lu
Date: Sat Jan 21 2012 - 05:24:51 EST
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.
