Hi Bjorn, Rafael,

Just kindly ping for this patchset, it has been reviewed and tested,
can it be merged in 4.3?

ARM64 ACPI PCI patches is based on this one, if this patchset is merged,
there will be less dependence for ARM64 ACPI PCI.

Thanks
Hanjun

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.

V4-V5:
1) As suggested by Lorenzo Pieralisi <lorenzo.pieralisi@xxxxxxx>, 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
