/*
* generic msqid64_ds structure.
*
* Note extra padding because this structure is passed back and forth
* between kernel and user space.
*
* msqid64_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 three padding words.
* On big-endian systems, the padding is in the wrong place.
*
* Pad space is left for:
* - 64-bit time_t to solve y2038 problem
* - 2 miscellaneous 32-bit values
