Subject: [Patch v6 0/7] Consolidate ACPI PCI root common code into ACPI core

This patch set consolidates common code to support ACPI PCI root on x86
and IA64 platforms into ACPI core, to reproduce duplicated code and
simplify maintenance. And a patch set based on previous version to support
ACPI based PCIe host bridge on ARM64 has been posted at:
https://lkml.org/lkml/2015/5/26/207

It's based on latest mainstream kernel. It passes Fengguang's 0day test
suite and has been tested on two IA64 platforms and one x86 platform.

V5->V6:
1) Patch 5 to reset domain number to 0 when pci_ignore_seg is set
2) Remove parameter segment and node from function acpi_pci_root_create(),
   as suggested by Lorenzo and Bjorn.
V4-V5:
1) As suggested by Lorenzo Pieralisi <lorenzo.pieralisi@....com>, do not
   introduce "struct pci_controller" into generic drivers/acpi/pci_root.c,
   so ARM64 doesn't need to define a useless structure. And it simplifies
   code a little too.

V3->V4:
1) Add patch[05/08] support solve building issue on ARM64
2) Solve an implicitly pointer cast issue.
3) Rebase to latest mainstream kernel

V2->V3:
1. Move memory allocation/free from ACPI core into arch
2. Kill the field 'segment' in struct pci_root_info on x86

Thanks!
Gerry

Jiang Liu (7):
  ACPI/PCI: Enhance ACPI core to support sparse IO space
  ia64/PCI/ACPI: Use common ACPI resource parsing interface for host
    bridge
  ia64/PCI: Use common struct resource_entry to replace struct
    iospace_resource
  PCI/ACPI: Consolidate common PCI host bridge code into ACPI core
  ACPI, PCI: Reset acpi_root_dev->domain to 0 when pci_ignore_seg is
    set
  x86/PCI/ACPI: Use common interface to support PCI host bridge
  ia64/PCI/ACPI: Use common interface to support PCI host bridge
