Masami Hiramatsu (1):
      ftrace/kprobe: Show the maxactive number on kprobe_events

Nathan Chancellor (1):
      tracing: Use address-of operator on section symbols

Steven Rostedt (VMware) (19):
      selftest/ftrace: Fix function trigger test to handle trace not disabling the tracer
      tracing: Save off entry when peeking at next entry
      ring-buffer: Have ring_buffer_empty() not depend on tracing stopped
      ring-buffer: Rename ring_buffer_read() to read_buffer_iter_advance()
      ring-buffer: Add page_stamp to iterator for synchronization
      ring-buffer: Have rb_iter_head_event() handle concurrent writer
      ring-buffer: Do not die if rb_iter_peek() fails more than thrice
      ring-buffer: Optimize rb_iter_head_event()
      ring-buffer: Make resize disable per cpu buffer instead of total buffer
      ring-buffer: Do not disable recording when there is an iterator
      tracing: Do not disable tracing when reading the trace file
      ring-buffer/tracing: Have iterator acknowledge dropped events
      tracing: Have the document reflect that the trace file keeps tracing enabled
      ftrace: Make function trace pid filtering a bit more exact
      ftrace: Create set_ftrace_notrace_pid to not trace tasks
      tracing: Create set_event_notrace_pid to not trace tasks
      selftests/ftrace: Add test to test new set_ftrace_notrace_pid file
      selftests/ftrace: Add test to test new set_event_notrace_pid file
      tracing: Add documentation on set_ftrace_notrace_pid and set_event_notrace_pid
