[PATCH v4 0/5] vfio: type1: support for ARM SMMUS with VFIO_IOMMU_TYPE1

[Baptiste Reynal <b.reynal-lrHrjnjw1UfHK3s98zE1ajGjJy/sRE9J@public.gmane.org>]

This patch series makes the VFIO_IOMMU_TYPE1 driver buildable on ARM, so it
may be used with ARM SMMUs. It also adds support for the IOMMU_NOEXEC flag
supported by SMMUs adhering to the ARM SMMU specification so the VFIO user can
specify whether the target memory can be executed by the device behind the
SMMU.

Changes from v3:
 - Rebased on linux v4.0-rc1
 - Use bit shifting for domain->caps
 - Baptiste Reynal is the new maintainer of this serie
Changes from v2:
 - Rebased on latest iommu/next branch by Joerg Roedel
Changes from v1:
 - Bugfixes and corrected some typos
 - Use enum for VFIO IOMMU driver capabilities

Antonios Motakis (5):
  vfio: implement iommu driver capabilities with an enum
  vfio: introduce the VFIO_DMA_MAP_FLAG_NOEXEC flag
  vfio: type1: replace domain wide protection flags with supported
    capabilities
  vfio: type1: replace vfio_domains_have_iommu_cache with generic
    function
  vfio: type1: implement the VFIO_DMA_MAP_FLAG_NOEXEC flag
