it's one of these recent commits:

fa7c7f6: tracing/core: remove unused parameter in tracing_fill_pipe_page()
6eaaa5d: tracing/core: use appropriate waiting on trace_pipe
35ebf1c: ftrace: show unlimited when traceon or traceoff has no counter
73d8b8b: tracing: fix typing mistake in hint message and comments
d2ef7c2: tracing: fix the return value of trace selftest
af51309: tracing: use the more proper parameter
b6887d7: ftrace: rename _hook to _probe
6a24a24: ftrace: clean up coding style

Have not bisected it any further, excluded them from tip:master
for the time being.
