Subject[PATCH -v9 00/24] PCI: allocate pci bus num range for unassigned bridge busn
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.

could be found at:
git:// for-pci-busn-alloc

need to apply to top of pci/for-linus plus pci/linux-next plus
[PATCH -v2] PCI: pci_host_bridge related cleanup

-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.



Yinghai Lu (24):
x86, PCI: add print all root info for nocrs path
x86, PCI: Merge pcibios_scan_root and pci_scan_bus_on_node
PCI: Add busn_res into struct pci_bus.
PCI: Add busn_res operation functions
PCI: release busn when removing bus
PCI: insert busn_res in pci_create_root_bus
PCI: checking busn_res in pci_scan_root_bus
PCI: default busn_resource
PCI: add default res for pci_scan_bus
x86, PCI: put busn resource in pci_root_info for acpi path
x86, PCI: put busn resource in pci_root_info for no_crs path
PCI, ia64: Register busn_res for root buses
PCI, sparc: Register busn_res for root buses
PCI, powerpc: Register busn_res for root buses
PCI, parisc: Register busn_res for root buses
PCI: Add pci_bus_extend/shrink_top()
PCI: Probe safe range that we can use for unassigned bridge.
PCI: Strict checking of valid range for bridge
PCI: Allocate bus range instead of use max blindly
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
