Merge tag 'docs-6.7' of git://git.lwn.net/linux

Pull documentation updates from Jonathan Corbet:
 "The number of commits for documentation is not huge this time around,
  but there are some significant changes nonetheless:

   - Some more Spanish-language and Chinese translations

   - The much-discussed documentation of the confidential-computing
     threat model

   - Powerpc and RISCV documentation move under Documentation/arch -
     these complete this particular bit of documentation churn

   - A large traditional-Chinese documentation update

   - A new document on backporting and conflict resolution

   - Some kernel-doc and Sphinx fixes

  Plus the usual smattering of smaller updates and typo fixes"
