+ * @cs: CPUState (must be valid, but treated as anonymous pointer)

+ * Used to flush all the translation blocks in the system. Sometimes
+ * it is simpler to flush everything than work out which individual
+ * translations are now invalid and ensure they are not called
+ * anymore.
+ *
+ * tb_flush() takes care of running the flush in an exclusive context
+ * if it is not already running in one. This means no guest code will
+ * run until this complete.
