Merge tag 'docs-6.6' of git://git.lwn.net/linux

Pull documentation updates from Jonathan Corbet:
"Documentation work keeps chugging along; this includes:

- Work from Carlos Bilbao to integrate rustdoc output into the
generated HTML documentation. This took some work to figure out how
to do it without slowing the docs build and without creating people
who don't have Rust installed, but Carlos got there

- Move the loongarch and mips architecture documentation under
Documentation/arch/

- Some more maintainer documentation from Jakub

... plus the usual assortment of updates, translations, and fixes"
