Pull tracing cleanups and bugfixes from Steven Rostedt:
"One bug fix that goes back to 3.10. Accessing a non existent buffer
if "possible cpus" is greater than actual CPUs (including offline
CPUs).
Namhyung Kim did some reviews of the patches I sent this merge window
and found a memory leak and had a few clean ups"
* tag 'trace-3.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
tracing: Fix check of ftrace_trace_arrays list_empty() check
tracing: Fix leak of per cpu max data in instances
tracing: Cleanup saved_cmdlines_size changes
ring-buffer: Check if buffer exists before polling
