Note, I still have more in my queue that need to go through testing.

Dan Carpenter (1):
      tracing: Have trace_stack nr_entries compare not be so subtle

Joe Lawrence (1):
      scripts/recordmcount.{c,pl}: support -ffunction-sections .text.* section names

Masami Hiramatsu (11):
      tracing/uprobes: Add busy check when cleanup all uprobes
      tracing: Lock event_mutex before synth_event_mutex
      tracing: Simplify creation and deletion of synthetic events
      tracing: Integrate similar probe argument parsers
      tracing: Add unified dynamic event framework
      tracing/kprobes: Use dyn_event framework for kprobe events
      tracing/uprobes: Use dyn_event framework for uprobe events
      tracing: Use dyn_event framework for synthetic events
      tracing: Remove unneeded synth_event_mutex
      tracing: Add generic event-name based remove event method
      selftests/ftrace: Add testcases for dynamic event

Steven Rostedt (VMware) (17):
      function_graph: Remove unused task_curr_ret_stack()
      tracing: Do not line wrap short line in function_graph_enter()
      fgraph: Create a fgraph.c file to store function graph infrastructure
      fgraph: Have set_graph_notrace only affect function_graph tracer
      arm64: function_graph: Remove use of FTRACE_NOTRACE_DEPTH
      function_graph: Remove the use of FTRACE_NOTRACE_DEPTH
      ftrace: Create new ftrace_internal.h header
      function_graph: Do not expose the graph_time option when profiler is not configured
      fgraph: Move function graph specific code into fgraph.c
      tracing: Rearrange functions in trace_sched_wakeup.c
      fgraph: Add new fgraph_ops structure to enable function graph hooks
      function_graph: Move ftrace_graph_ret_addr() to fgraph.c
      function_graph: Have profiler use new helper ftrace_graph_get_ret_stack()
      ring-buffer: Add percentage of ring buffer full to wake up reader
      tracing: Add tracefs file buffer_percentage
      tracing: Change default buffer_percent to 50
      tracing: Consolidate trace_add/remove_event_call back to the nolock functions
