This patch set adds support for the SMMUv3 driver. This is a

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.
The SMMUv3 series looks in good state and I would like to see this
merged for Xen 4.11. Manish, do we have an update on the IORT side?
Started merging this series with my code.
Cheers,
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.
