[Xen-devel] [RFC v3 0/4] SMMUv3 Driver

[Sameer Goel <sgoel@xxxxxxxxxxxxxx>]

This RFC addresses the review comments from the last RFC [1].

All the IORT realted changes have been droped in this version as these will be
covered by [2]. The IORT implementation had to provide a Linux like API to the
SMMUv3 driver.

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.
