[PATCH v2 0/4] doc: update Kernel documentation build system

[Heinrich Schuchardt]

Update the documentation build system according to Linux v5.11-rc1.

Deactive the automarkup.py extension module which on Gitlab CI is
incompatible with Unicode.

With this patch we can build the HTML documentation using either of
Sphinx 2 and Sphinx 3.

Fix two non-conformant documents.
