Subject: [Patch v4 0/8] 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 this to support ACPI based
PCIe host bridge on ARM64 has been posted at:

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.

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

  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
  x86/PCI: Rename struct pci_sysdata as struct pci_controller
  PCI/ACPI: Consolidate common PCI host bridge code into ACPI core
