[Qemu-devel] [PULL 02/41] replay: improve interrupt handling |

From: Pavel Dovgalyuk <address@hidden>
This patch improves interrupt handling in record/replay mode.
Now "interrupt" event is saved only when cc->cpu_exec_interrupt returns true.
This patch also adds missing return to cpu_exec_interrupt function.
