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

From: Yinghai Lu
Date: Tue Feb 28 2012 - 17:28:58 EST


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://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.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.

Thanks

Yinghai
