Merge tag 'docs-4.13' of git://git.lwn.net/linux

Pull documentation updates from Jonathan Corbet:
 "There has been a fair amount of activity in the docs tree this time
  around. Highlights include:

   - Conversion of a bunch of security documentation into RST

   - The conversion of the remaining DocBook templates by The Amazing
     Mauro Machine. We can now drop the entire DocBook build chain.

   - The usual collection of fixes and minor updates"

-/*
- *	docproc is a simple preprocessor for the template files
- *      used as placeholders for the kernel internal documentation.
- *	docproc is used for documentation-frontend and
- *      dependency-generator.
- *	The two usages have in common that they require
- *	some knowledge of the .tmpl syntax, therefore they
- *	are kept together.
- *
- *	documentation-frontend
- *		Scans the template file and call kernel-doc for
- *		all occurrences of ![EIF]file
- *		Beforehand each referenced file is scanned for
- *		any symbols that are exported via these macros:
- *			EXPORT_SYMBOL(), EXPORT_SYMBOL_GPL(), &
- *			EXPORT_SYMBOL_GPL_FUTURE()
- *		This is used to create proper -function and
- *		-nofunction arguments in calls to kernel-doc.
- *		Usage: docproc doc file.tmpl
- *
- *	dependency-generator:
- *		Scans the template file and list all files
- *		referenced in a format recognized by make.
- *		Usage:	docproc depend file.tmpl
- *		Writes dependency information to stdout
- *		in the following format:
- *		file.tmpl src.c	src2.c
- *		The filenames are obtained from the following constructs:
- *		!Efilename
- *		!Ifilename
- *		!Dfilename
- *		!Ffilename
- *		!Pfilename
