- * aligned_u64 should be used in defining kernel<->userspace ABIs to avoid
- * common 32/64-bit compat problems.
- * 64-bit values align to 4-byte boundaries on x86_32 (and possibly other
- * architectures) and to 8-byte boundaries on 64-bit architetures. The new
- * aligned_64 type enforces 8-byte alignment so that structs containing
- * aligned_64 values have the same alignment on 32-bit and 64-bit architectures.
- * No conversions are necessary between 32-bit user-space and a 64-bit kernel.
