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 v4:
- Remove domain->caps, use iommu capacity flags instead
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

vfio: introduce the VFIO_DMA_MAP_FLAG_NOEXEC flag
vfio: type1: replace vfio_domains_have_iommu_cache with generic
