A better changelog:

  ~15 years ago kprobes grew the 'arch_deref_entry_point()' __weak function:

    3d7e33825d87: ("jprobes: make jprobes a little safer for users")

  But this is just open-coded dereference_symbol_descriptor() in essence, and
  its obscure nature was causing bugs.

  Just use the real thing.

Thanks,
