| * The semid64_ds structure for x86 architecture. |
| * Note extra padding because this structure is passed back and forth |
| * between kernel and user space. |
| * semid64_ds was originally meant to be architecture specific, but |
| * everyone just ended up making identical copies without specific |
| * optimizations, so we may just as well all use the same one. |
| * 64 bit architectures typically define a 64 bit __kernel_time_t, |
| * so they do not need the first two padding words. |
| * On big-endian systems, the padding is in the wrong place. |
| * - 64-bit time_t to solve y2038 problem |
| * - 2 miscellaneous 32-bit values |
