Merge branch 'bpf-formatting-fixes-helpers'

Quentin Monnet says:

====================
Here is a follow-up set for eBPF helper documentation, with two patches
to fix formatting issues:

- One to fix an error I introduced with the initial set for the doc.
- One for the newly added bpf_get_stack(), that is currently not parsed
  correctly with the Python script (function signature is fine, but
  description and return value appear as empty).

There is no change to text contents in this set.
