These patches have been part of:
[PATCH v4 00/10] ACPI GIC Self-probing, GICv2m and GICv3 support
https://lkml.org/lkml/2015/7/29/234

Patches base on Suravee's ACPI GICv2m support:

The following git branch contains submitted patches along with
the useful for test patches (mainly ACPI ARM64 PCI support).

Series has been tested on Cavium ThunderX 1 socket server.

v1 -> v2
- rebased on top of 4.4-rc4
- use pci_msi_domain_get_msi_rid for requester ID to device ID translation
