[PATCH 00/47] PCI, x86: pci root bus hotplug support

[Yinghai Lu]

will add pci_stop_and_remove_bus() to support remove bus in
/sys/devices/pci.../pci_bus/...

To rescan root, need to
echo 1 > /sys/bus/pci/rescan_root

It supports acpi path root bus and legacy root bus.

This patcheset include some IOMM and dmar and pnpacpi fix with device refcount leaking.
        also include some bus remove/rescan cleanup.

The patches need to apply to pci/for-linus and pci/linux-next
	[PATCH -v3] PCI: pci_host_bridge related cleanup
	[PATCH -v11] PCI: allocate pci bus num range for unassigned bridge busn

could get from
        git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-root-bus-hotplug

-v2: Address most of Bjorn's review, except still keeping .../pci_bus/.../remove
     Separate pci root hot add support from acpiphp to pci_root_hp
     add hot removal to pci_root_hp
-v3: Reordering the patches about /sys changes at last that Bjorn objects.
     Claim hw/fw allocated bus after root bus hot add.
     add two patches for Jiang Liu about removal.

Ashok Raj (1):
  ACPI: Enable SCI_EMULATE to manually simulate physical hotplug
    testing.

Jiang Liu (2):
  Correctly clean up pci root buses in function pci_remove_bus()
  Fix an access-after-free issue in function pci_stop_and_remove_bus()

  PCI: Claim hw/fw allocated resources in hot add path.
  PCI: Move pci_stop_and_remove_behind_bridge() down
  PCI: Add __pci_remove_bus_devices()
  PCI: Use list_for_each_entry_safe instead of list_for_each_safe
  PCI: Add pci_stop_and_remove_bus()
  PCI, ACPI: Make acpi_pci_root_remove remove pci root bus too
  PCI, acpiphp: Separate out hot-add support of pci host bridge
  PCI, ACPI: Add pci_root_hp hot removal notification support.
  PCI, ACPI: Add alloc_acpi_hp_work()
  PCI, acpiphp: Use acpi_hp_work
  PCI, pci_root_hp: Use acpi_hp_work
  PCI, ACPI: Make kacpi_hotplug_wq static
  PCI: Add debug print out for pci related dev release
  PCI, pciehp: Separate pci_hp_add_bridge()
  PCI, cphi_hotplug: Simplify configure_slot
  PCI, shpchp: Simplify configure_device
  PCI: Kill pci_is_reassignedev()
  PCI, sysfs: Prepare to kill pci device rescan
  PCI: Add pci bus removal through /sys/.../pci_bus/.../remove
  PCI, ACPI: Add acpi_pci_root_rescan()
  PCI: Add __pci_scan_root_bus() that can skip bus_add

  x86, PCI: Add pcibios_root_rescan()
  x86, PCI: Add arch version pci_root_rescan()
  PCI: Add /sys/bus/pci/rescan_root
