Linus Torvalds f20730efbd SMP cross-CPU function-call updates for v6.4:
- Remove diagnostics and adjust config for CSD lock diagnostics
 
  - Add a generic IPI-sending tracepoint, as currently there's no easy
    way to instrument IPI origins: it's arch dependent and for some
    major architectures it's not even consistently available.
