[Xen-devel] [PATCH 0/7] SMMUv3 driver

[Sameer Goel <sameer.goel@xxxxxxxxxx>]

This patch set adds support for the SMMUv3 driver. This is a continuation on
a RFCv4.[1]
The IORT support came from [2]. This RFC has some conflicting defines that
have to be addressed by introducing the linux_compat.h header in IORT patch
set. In any case the SMMU changes apply on top of IORT patches.

List of changes:
- Addition of a linux_compat header.
- Addition of a common header for arm smmu defines.
- Rebase of the SMMUv3 driver to the driver in linux kernel 4.14 rc7.
- New config defines for ARM SMMU drivers.
