Maybe; I noticed that too but it's also missing in the old x86 unistd_32.h.
I thought Linux only provided the ipc(2) call - glibc sources seem to confirm that (sysdeps/unix/sysv/linux/semget.c).
sys_sem* and friends are present in include/asm-generic/unistd.h so maybe these values just need to be propagated to syscall_32.tbl?
Actually there's a bunch of SysV IPC calls defined in syscall_64.tbl that are not present in syscall_32.tbl:
$ egrep 'shm|sem|msg[a-z]' arch/x86/syscalls/syscall_32.tbl $ egrep 'shm|sem|msg[a-z]' arch/x86/syscalls/syscall_64.tbl 29 64 shmget sys_shmget 30 64 shmat sys_shmat 31 64 shmctl sys_shmctl 64 64 semget sys_semget 65 64 semop sys_semop 66 64 semctl sys_semctl 67 64 shmdt sys_shmdt 68 64 msgget sys_msgget 69 64 msgsnd sys_msgsnd 70 64 msgrcv sys_msgrcv 71 64 msgctl sys_msgctl 220 64 semtimedop sys_semtimedop But sys_ipc is there:
$ grep sys_ipc arch/x86/syscalls/syscall_32.tbl 117 i386 ipc sys_ipc sys32_ipc
