Merge tag 'trace-unused-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull tracepoint cleanup from Steven Rostedt:
 "Remove or hide unused tracepoints

  Tracepoints take up memory (around 5K per tracepoint) even when they
  are unused. Changes are being made to detect when a tracepoint is
  defined but unused and a warning is shown at build. But those changes
  are not yet ready for inclusion.

   - Fix some of the unused tracepoints that it detected

     Some tracepoints were removed and others were hidden by config
     settings to match the config settings of where they are
     instantiated. Some tracepoints were moved into architecture
     specific code as only one architecture used them.

   - Call the ftrace_test_filter tracepoint in an unreachable if
     statement

     The ftrace_test_filter tracepoint which is defined when ftrace
     selftests are configured and is used to test the filter logic, but
     the tracepoint is not actually called. It is put into an if
     statement to not have it get compiled out, but also not warn for
     not being used"
