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. The common code should also used to support PCI host bridge on ARM64 too, but I'm lacking of knowledge about PCIe host bridge implementation details on ARM64, so please help to review whether this is suitable for ARM64 too. It's based on latest mainstream kernel plus the patch to fix a regression at: http://lkml.org/lkml/2015/4/30/13 It passes Fengguang's 0day test suite and has been tested on two IA64 platforms and one x86 platform. The patch set is available at: https://github.com/jiangliu/linux.git acpi_pci_root_v2 Thanks!
