[PATCH 0/4] perf: remove unused functions

[David Ahern]

Hi Arnaldo:

Going through my backlog of perf cleanup patches. These remove unused
functions and then makes a sole callee static.

David Ahern (4):
  perf: remove unused print_event function
  perf: remove unused print_trace_event function
  perf: remove unused perf_session__remove_thread
  perf: move machine__remove_thread and make static
