By removing the requirement to add IPC_64 you remove the need for a
special wrapper, and the syscalls can be implemented by just adding it
to syscalls.list.  That should be the goal for every new syscall.  Also,
it doesn't make sense to offer obsolete interfaces (the non-IPC_64
variants) through such syscalls.

Andreas.
