Merge tag 'docs-6.0' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"This was a moderately busy cycle for documentation, but nothing
all that earth-shaking:
- More Chinese translations, and an update to the Italian
translations.
The Japanese, Korean, and traditional Chinese translations
are more-or-less unmaintained at this point, instead.
- Some build-system performance improvements.
- The removal of the archaic submitting-drivers.rst document,
with the movement of what useful material that remained into
other docs.
- Improvements to sphinx-pre-install to, hopefully, give more
useful suggestions.
- A number of build-warning fixes
Plus the usual collection of typo fixes, updates, and more"
