Hi Arnd,
The following commit breaks the semctl/shmctl/msgctl syscalls on
64-bit sparc userland (but not on 32-bit sparc userland)

ipc: rename old-style shmctl/semctl/msgctl syscalls
The LTP test case semctl01 can quickly reproduce the failure, but I
initially noticed this failure in the Perl test suite. Looks like the
syscalls always return EINVAL now. Funny, the commit doesn't even
touch arch/sparc :)
arch/sparc/include/uapi/asm/unistd.h
Defines __32bit_syscall_numbers__ if __arch64__
arch/sparc/include/asm/unistd.h
Includes arch/sparc/include/uapi/asm/unistd.h
Defines __ARCH_WANT_SYS_IPC if __32bit_syscall_numbers__
ipc/syscall.c
Looks like it defines different paths for __ARCH_WANT_SYS_IPC vs not
I get lost at this point, but I'm guessing that's where the difference
between 32-bit and 64-bit comes from.
Any ideas? I'm happy to test patches.
Thanks,
Matt
