+struct iommu_hw_info {

• __u32 size;
• __u32 flags;
• __u32 dev_id;
• __u32 data_len;
• __aligned_u64 data_ptr;
• __u32 out_data_type;
• __u32 __reserved;

it's unusual to have reserved field in the end. It makes more sense to move data_ptr to the end to make it meaningful.

Please ignore this comment. typed too fast...
