[Qemu-devel] [PULL for-2.0 2/7] linux-user: Don't return uninitialized value for atomic_barrier syscall

[riku . voipio]

From: Peter Maydell <address@hidden>

QEMU's implementation of the m68k atomic_barrier syscall, like the kernel's,
is just a no-op. However we still need to return a result code from it.
