    y2038: x86: Extend sysvipc data structures · c039dbd5
    Arnd Bergmann authored
    This extends the x86 copy of the sysvipc data structures to deal with
    32-bit user space that has 64-bit time_t and wants to see timestamps
    beyond 2038.
    
    Fortunately, x86 has padding for this purpose in all the data structures,
    so we can just add extra fields. With msgid64_ds and shmid64_ds, the
    data structure is identical to the asm-generic version, which we have
    already extended.
    
    For some reason however, the 64-bit version of semid64_ds ended up with
    extra padding, so I'm implementing the same approach as the asm-generic
    version here, by using separate fields for the upper and lower halves
    of the two timestamps.
