4.6-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jean-Philippe Brucker <[email protected]> commit 9aeb26cfc2abc96be42b9df2d0f2dc5d805084ff upstream. The map_sg callback is missing from arm_smmu_ops, but is required by iommu.h. Similarly to most other IOMMU drivers, connect it to default_iommu_map_sg.
