[GIT PULL] tracing: Remove or hide some unused tracepoints for 6.17

[Steven Rostedt]

Linus,

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.
