摘要： Embodiments of the invention include a method of synchronizing translation changes in a processor including a translation lookaside buffer, the method including setting a control bit to enable blocking of all fetch requests that miss the translation lookaside buffer without changing a translation state of the current process; if there is at least one pending translation, then waiting for completion of the at least one pending translation; and resetting the control bit. A processor and a computer program product are provided.
