The conditional memory barrier not only looks strange but actually is wrong. On s390x, I can reproduce interrupts via cpu_interrupt() not leading to a proper kick out of emulation every now and then. cpu_interrupt() is especially used for inter CPU communication via SIGP (esp. external calls and emergency interrupts). With this patch, I was not able to reproduce. (esp. no stalls or hangs in the guest). My setup is s390x MTTCG with 16 VCPUs on 8 CPU host, running make -j16.
