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.
This applies on top of the branch 'next' by Joerg Roedel available at
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git
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
