ACPI core patches for ARM64 are now upstreamed in 4.1. The PCI support
patches for ARM64 ACPI are also in progress. I am sending out this RFC to
introduce ACPI support for GICv2m. This would allow MSI to work when
booting ACPI.

There are some modifications to the irq_domain and acpi/gsi code.

Due to a large number of prerequisite patches, I have put together a branch
on GitHub for review and testing:

	https://github.com/ssuthiku/linux.git acpi-pci-msi-rfc2

This branch has been tested on AMD Seattle Platform. Any feedback and
comments are appreciated.

Thank you in advance,

Suravee

Changes in RFC2:
    - Rebased to V3 of Introducing per-device MSI domain
      (from Marc Zyngier)
    - Rebased to V2 of Add seld-probe infrastructure and stacked
      irqdomain support for APCI based GICv2/3 init
      (from Hanjun Guo)
    - Introduce GIC MSI frame handle.

Suravee Suthikulpanit (8):
  irqdomain: Introduce irq_domain_ops.init_alloc_info
  gic: Introduce gic_init_irq_alloc_info()
  gicv2m: Convert to use GIC irq_domain_ops.init_alloc_info
  acpi: gsi: Adding acpi_init_irq_alloc_info() hook
  arm64: Adding arch-specific acpi_init_irq_alloc_info
  gic: acpi: Introduce GIC MSI frame handle and helper functions
  gicv2m: Introducing gicv2m_acpi_init()
  pci: acpi: Bind GICv2m MSI frame to PCI host bridge
