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:

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.

1) As suggested by Lorenzo Pieralisi <lorenzo.pieralisi at arm.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.

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

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


Jiang Liu (6):
  ACPI/PCI: Enhance ACPI core to support sparse IO space
  ia64/PCI/ACPI: Use common ACPI resource parsing interface for host
  ia64/PCI: Use common struct resource_entry to replace struct
  PCI/ACPI: Consolidate common PCI host bridge code into ACPI core
  x86/PCI/ACPI: Use common interface to support PCI host bridge
  ia64/PCI/ACPI: Use common interface to support PCI host bridge
