Subject: [PATCH -v12 00/15] PCI: allocate pci bus num range for unassigned bridge busn

busn_res already in next. and this patchset will
will try to allocate busn range from the tree

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

-v2: according to Jesse, split to more small patches.
-v3: address some request from Bjorn. like make use %pR for busn_res debug print
        out, and move the comment change with code change.
-v4: fixes the problem about rescan that Bjorn found.
-v5: add /proc/iobusn that is requested by Bjorn.
     remove old workaround from pciehp.
     add rescan_bridge for pci bridge in /sys
-v6: remove global iobusn_resource, and every root bus's busn_res will be root
     of children buses' busn_res.
     pc cardbus change is tested by pcmcia maintainter.
-v7: remove pci_scan_root_bus_max requested by Bjorn and Jesse.
-v8: rebase on top other patches with arch/x86/pci/bus_numa.c changes
     also only include busn_res related changes.
-v9: Add busn into pci_root_info, and add it to resources list and pass it
     to pci_create_root_bus.
-v11: convert busn_res probe to generic probe_resource with resource lock holding
     add more strict checking about not scaned peer bridges.
-v12: updated after busn_resource changes.

Yinghai Lu (15):
  resources: Split out __allocate_resource()
  resources: Add probe_resource()
  resources: Replace registered resource in tree.
  PCI: Add pci_bus_extend/shrink_top()
  PCI: Probe safe range that we can use for unassigned bridge.
  PCI: Add pci_bus_replace_busn_res()
  PCI: Allocate bus range instead of use max blindly
  PCI: Strict checking of valid range for bridge
  PCI: Kill pci_fixup_parent_subordinate_busnr()
  PCI: Seperate child bus scanning to two passes overall
  pcmcia: Remove workaround for fixing pci parent bus subordinate
  PCI: Double checking setting for bus register and bus struct.
  PCI, pciehp: Remove not needed bus number range checking
  PCI: More strict checking of valid range for bridge
  PCI: Don't shrink too much for hotplug bridge
