 * Make sure that all structs defined in this file remain laid out so

 * avoid incompatibility between 32-bit userspace and 64-bit kernels).
 * Specifically:
 *  - Do not use pointer types -- pass pointers in __u64 instead.
 *  - Make sure that any structure larger than 4 bytes is padded to a
 *    multiple of 8 bytes.  Otherwise the structure size will be
 *    different between 32-bit and 64-bit architectures.
