[GIT PULL] ACPI IORT changes for v4.15

[GIT PULL] ACPI IORT changes for v4.15

[Lorenzo Pieralisi]

Hi Catalin, Will,

here are the ACPI IORT changes I have queued aimed at the v4.15 kernel
release.

Main changes:

- SMMUv3 MSI enablement work based on IORT issue C spec updates
  (Hanjun Guo)
- Clean-ups/rework in preparation for PMCG support (Lorenzo Pieralisi)

Patches have a compile time dependency on the ACPICA tree that we handled
through an ACPI_CA_VERSION guard; I will remove it at v4.15-rc1 when
dependencies have settled.

Reference discussion:

http://lkml.kernel.org/r/20171013130445.GA27895 at red-moon

I expect no merge conflict with the arm64 tree for-next/core branch.

Patches are based on v4.14-rc4 owing to an IORT dependency on a fix
(ie commit 37f6b42e9c ("ACPI/IORT: Fix PCI ACS enablement")) that
was merged in v4.14-rc4.

Please consider pulling, thank you.

Lorenzo

As discussed offline, given that this is a trivial one-line conflict as
opposed to a functional dependency, could you please send another pull
request based on -rc3? The arm64 for-next/core branch is already based on
that, and this doesn't seem like a good reason to pull in -rc4.

Cheers,

Will
