An element in scatterlist may not be aligned by 4K but I think IOMMU driver must round it up to 4K if IOMMU API support iommu_map_range(). The first element in scatterlist is often not aligned by 4K if the pages are provided from userspace. Length + offset of the element must be aligned by 4K, though.
