  (Mark Santaniello)

- Support function filtering in 'perf ftrace' (Namhyung Kim)

- Allow specifying function call depth in 'perf ftrace' (Namhyumg Kim)

Infrastructure changes:

- Adopt __noreturn, __printf, __scanf, noinline, __packed and __aligned
  __alignment__(()) markers, to make the tools/ source code base to be
  more compact and look more like kernel code (Arnaldo Carvalho de Melo)

- Remove unnecessary check in annotate_browser_write() (Jin Yao)

- Return arch from symbol__disassemble() so that callers, such as
  the annotate TUI browser to use arch specific formattings, such

  Phillips)

- Remove unused SAMPLE_SIZE defines and BTS priv array (Kim Phillips)
