As this does not work for most of the other combinations, we just handle it in the common manner though. * semid64_ds has no padding for 64-bit time_t, but has two reserved 'long' fields, which are sufficient to extend the sem_otime and sem_ctime fields to 64 bit. In order to do this, the libc implementation will have to copy the data into another structure that has the fields in a different order. MIPS is the only architecture with this problem, so this is best done in MIPS specific libc code. * shmid64_ds is slightly worse than that, because it has three time_t fields but only two unused 32-bit words. As a workaround, we extend each field only by 16 bits, ending up with 48-bit timestamps that user space again has to work around by itself. The compat versions of the data structures are changed in the same way.
