This already happened as part of the 32-bit UID merge in Linux 2.3.39.
Check include/asm-{arch}/{ipcbuf,msgbuf,sembuf,shmbuf}.h for the new IPC
interface.

We now have: 32 bits for uid,gid
                64 bits for time_t
                machine word size (32 or 64) for sizes
                32 bits for pid

in all the IPC structures passed to/from user programs.

Thanks,
