Linus Torvalds d2a6fd45c5 Probes updates for v6.5:
- fprobe: Pass return address to the fprobe entry/exit callbacks so that
   the callbacks don't need to analyze pt_regs/stack to find the function
   return address.
 
 - kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN
   flags so that those are not set at once.
 
 - fprobe events:
  . Add a new fprobe events for tracing arbitrary function entry and
    exit as a trace event.
  . Add a new tracepoint events for tracing raw tracepoint as a trace
    event. This allows user to trace non user-exposed tracepoints.
  . Move eprobe's event parser code into probe event common file.
  . Introduce BTF (BPF type format) support to kernel probe (kprobe,
    fprobe and tracepoint probe) events so that user can specify traced
    function arguments by name. This also applies the type of argument
    when fetching the argument.
  . Introduce '$arg*' wildcard support if BTF is available. This expands
    the '$arg*' meta argument to all function argument automatically.
  . Check the return value types by BTF. If the function returns 'void',
    '$retval' is rejected.
  . Add some selftest script for fprobe events, tracepoint events and
    BTF support.
  . Update documentation about the fprobe events.
  . Some fixes for above features, document and selftests.
 
 - selftests for ftrace (except for new fprobe events):
  . Add a test case for multiple consecutive probes in a function which
    checks if ftrace based kprobe, optimized kprobe and normal kprobe
    can be defined in the same target function.
  . Add a test case for optimized probe, which checks whether kprobe
    can be optimized or not.

Pull probes updates from Masami Hiramatsu:

 - fprobe: Pass return address to the fprobe entry/exit callbacks so
   that the callbacks don't need to analyze pt_regs/stack to find the
   function return address.

 - kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN
   flags so that those are not set at once.

 - fprobe events:
      - Add a new fprobe events for tracing arbitrary function entry and
        exit as a trace event.
      - Add a new tracepoint events for tracing raw tracepoint as a
        trace event. This allows user to trace non user-exposed
        tracepoints.
      - Move eprobe's event parser code into probe event common file.
      - Introduce BTF (BPF type format) support to kernel probe (kprobe,
        fprobe and tracepoint probe) events so that user can specify
        traced function arguments by name. This also applies the type of
        argument when fetching the argument.
      - Introduce '$arg*' wildcard support if BTF is available. This
        expands the '$arg*' meta argument to all function argument
        automatically.

        and BTF support.
      - Update documentation about the fprobe events.
      - Some fixes for above features, document and selftests.

 - selftests for ftrace (in addition to the new fprobe events):
      - Add a test case for multiple consecutive probes in a function
        which checks if ftrace based kprobe, optimized kprobe and normal
        kprobe can be defined in the same target function.
      - Add a test case for optimized probe, which checks whether kprobe
        can be optimized or not.
