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!
