Hi,

In the first patchset, my intension was to remove trace_probe_tmpl.h,
just keep a unified process_fetch_insn and process_fetch_insn_bottom
in trace_probe.c for all *probes. is_uprobe was the most important
move to approach. If it was not accepted, the whole patchset couldn't
stand.

Then I change my goal to at least no warnings or errors when impelenting
a new feature based on trace probe if it includes trace_probe_tmpl.h by
provideing default behaviors. What's more, it also removes redundant
code in kprobe and eprobe.

---
v2:
1, reorganize patchset.

v3:
1, mark nokprobe_inline for get_event_field.
2, remove warnings reported from kernel test robot.
3, fix errors reported from kernel test robot.

v4:
1, reset changes in v3(2) and v3(3), they are not reasonable fix.
2, fixed errors by adding "#ifdef CONFIG_HAVE_REGS_AND_STACK_ACCESS_API".

Song Chen (2):
  kernel/trace: Introduce trace_probe_print_args and use it in *probes
  kernel/trace: Provide default impelentations defined in
    trace_probe_tmpl.h
