From 3b899ea7d405dc7634ac629aa7b0e7639d506d9f Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Wed, 12 Mar 2014 13:06:01 +0000 Subject: [PATCH] linux-user: Don't return uninitialized value for atomic_barrier syscall 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.
