6 * The msqid64_ds structure for the MIPS architecture.
7 * Note extra padding because this structure is passed back and forth
8 * between kernel and user space.
10 * Pad space is left for:
11 * - extension of time_t to 64-bit on 32-bitsystem to solve the y2038 problem
12 * - 2 miscellaneous unsigned long values
