Merge tag 'probes-v6.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace...

Pull kprobes cleanup updates from Masami Hiramatsu:
 "These are probe events cleanups, no new features but improve
  readability:

   - Rename print_probe_args() to trace_probe_print_args() and
     un-inline it

   - Introduce a set of default data fetch functions for dynamic
     probe events

   - Extract common code of data fetch process of dynamic probe events"

* tag 'probes-v6.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace:
  kernel/trace: extract common part in process_fetch_insn
  kernel/trace: Provide default impelentations defined in trace_probe_tmpl.h
  kernel/trace: Introduce trace_probe_print_args and use it in *probes
