Pull documentation updates from Jonathan Corbet:
 "It has been a moderately busy cycle for documentation; some of the
  highlights are:

   - Numerous PDF-generation improvements

   - Kees's new document with guidelines for researchers studying the
     development community.

   - The ongoing stream of Chinese translations

   - Thorsten's new document on regression handling

   - A major reworking of the internal documentation for the kernel-doc
     script.

  Plus the usual stream of typo fixes and such"
