12  * tb_flush() - flush all translation blocks
13  * @cs: CPUState (must be valid, but treated as anonymous pointer)
14  *
15  * Used to flush all the translation blocks in the system. Sometimes
16  * it is simpler to flush everything than work out which individual
17  * translations are now invalid and ensure they are not called
18  * anymore.
19  *
20  * tb_flush() takes care of running the flush in an exclusive context
21  * if it is not already running in one. This means no guest code will
22  * run until this complete.
