3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: "zhangwei(Jovi)" <jovi.zhang...@huawei.com> commit f0160a5a2912267c02cfe692eac955c360de5fdf upstream. The TRACE_ITER_PRINTK check in __trace_puts/__trace_bputs is missing, so add it, to be consistent with __trace_printk/__trace_bprintk. Those functions are all called by the same function: trace_printk().
