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!
