Steven Rostedt (Red Hat) 3132e107d6 tracing: Check if tracing is enabled in trace_puts() 
If trace_puts() is used very early in boot up, it can crash the machine
if it is called before the ring buffer is allocated. If a trace_printk()
is used with no arguments, then it will be converted into a trace_puts()
and suffer the same fate.

Cc: stable@vger.kernel.org # 3.10+
Fixes: 09ae72348e "tracing: Add trace_puts() for even faster trace_printk() tracing"
