/*
* The semid64_ds structure for most architectures (though it came from x86_32
* originally). 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 use a 64-bit long time field here, while
* 32 bit architectures have a pair of unsigned long values.
*
* On big-endian systems, the padding is in the wrong place for
* historic reasons, so user space has to reconstruct a time_t
* value using
*
* user_semid_ds.sem_otime = kernel_semid64_ds.sem_otime +
* ((long long)kernel_semid64_ds.sem_otime_high << 32)
*
* Pad space is left for 2 miscellaneous 32-bit values
