The problem is actually related to changes happening in Sphinx 3.0.0.
There is the followign issue filled upstream:
https://github.com/sphinx-doc/sphinx/issues/7421
'c_funcptr_sig_re' was removed upstream in sphinx v3.0.0b1 and so the
kernel documentation build fails. This is reproducible with a recent
sphinx version (in attached case it is 3.2.0):
$ make PYTHON=python3 xmldocs
SPHINX xmldocs --> file:///home/build/linux/Documentation/output/xml
make[2]: Nothing to be done for 'xml'.
Running Sphinx v3.2.0
Extension error:
Could not import extension cdomain (exception: cannot import name 'c_funcptr_sig_re' from 'sphinx.domains.c' (/usr/lib/python3/dist-packages/sphinx/domains/c.py))
make[1]: *** [Documentation/Makefile:115: xmldocs] Error 2
make: *** [Makefile:1655: xmldocs] Error 2
