7 | * The semid64_ds structure for x86 architecture. | ||
8 | * Note extra padding because this structure is passed back and forth | ||
9 | * between kernel and user space. | ||
10 | * | ||
11 | * semid64_ds was originally meant to be architecture specific, but | ||
12 | * everyone just ended up making identical copies without specific | ||
13 | * optimizations, so we may just as well all use the same one. | ||
14 | * | ||
15 | * 64 bit architectures typically define a 64 bit __kernel_time_t, | ||
16 | * so they do not need the first two padding words. | ||
17 | * On big-endian systems, the padding is in the wrong place. | ||
18 | * | ||
19 | * Pad space is left for: | ||
20 | * - 64-bit time_t to solve y2038 problem | ||
21 | * - 2 miscellaneous 32-bit values | ||
