Subject: kernel-doc: move kernel-doc tools to scripts/

tools/kernel-doc/docproc.c and tools/kernel-doc/kernel-doc are
files imported from Linux Kernel.

They originally resided under scripts/ directory in Linux Kernel.

This commit moves them to the original location.

+ *
+ *	documentation-frontend

+ *		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

+# 18/01/2001 - 	Cleanups
+# 		Functions prototyped as foo(void) same as foo()
+# 		Stop eval'ing where we don't need to.
+# -- huggie@earth.li
+
+# 27/06/2001 -  Allowed whitespace after initial "/**" and
+#               allowed comments before function declarations.
+# -- Christian Kreibich <ck@whoop.org>
+
+# Still to do:
+# 	- add perldoc documentation
+# 	- Look more closely at some of the scarier bits :)
+
+# 26/05/2001 - 	Support for separate source and object trees.
+#		Return error code.
+# 		Keith Owens <kaos@ocs.com.au>
+
+# 23/09/2001 - Added support for typedefs, structs, enums and unions
+#              Support for Context section; can be terminated using empty line
+#              Small fixes (like spaces vs. \s in regex)
+# -- Tim Jansen <tim@tjansen.de>
+
+# 25/07/2012 - Added support for HTML5
+# -- Dan Luedtke <mail@danrl.de>
+
+#
+# This will read a 'c' file and scan for embedded comments in the
+# style of gnome comments (+minor extensions - see below).
+#
+
+# Note: This only supports 'c'.
+
+# usage:
+# kernel-doc [ -docbook | -html | -html5 | -text | -man | -list ]
+#            [ -no-doc-sections ]
+#            [ -function funcname [ -function funcname ...] ]
+#            c file(s)s > outputfile
+# or
+#            [ -nofunction funcname [ -function funcname ...] ]
+#            c file(s)s > outputfile
+#
+#  Set output format using one of -docbook -html -html5 -text or -man.
+#  Default is man.
+#  The -list format is for internal use by docproc.
+#
+#  -no-doc-sections
+#	Do not output DOC: sections
+#
+#  -function funcname
+#	If set, then only generate documentation for the given function(s) or
+#	DOC: section titles.  All other functions and DOC: sections are ignored.
+#
+#  -nofunction funcname
+#	If set, then only generate documentation for the other function(s)/DOC:
+#	sections. Cannot be used together with -function (yes, that's a bug --
+#	perl hackers can fix it 8))
+#
+#  c files - list of 'c' files to process
+#
+#  All output goes to stdout, with errors to stderr.
+
+#
+# format of comments.
+# In the following table, (...)? signifies optional structure.
+#                         (...)* signifies 0 or more structure elements
+# /**
+#  * function_name(:)? (- short description)?
+# (* @parameterx: (description of parameter x)?)*
+# (* a blank line)?
+#  * (Description:)? (Description of function)?
+#  * (section header: (section description)? )*
+#  (*)?*/
+#
+# So .. the trivial example would be:
+#
+# /**
+#  * my_function
+#  */
+#
+# If the Description: header tag is omitted, then there must be a blank line
+# after the last parameter specification.
+# e.g.
+# /**
+#  * my_function - does my stuff
+#  * @my_arg: its mine damnit
+#  *
+#  * Does my stuff explained.
+#  */
+#
+#  or, could also use:
+# /**
+#  * my_function - does my stuff
+#  * @my_arg: its mine damnit
+#  * Description: Does my stuff explained.
+#  */
+# etc.
+#
+# Besides functions you can also write documentation for structs, unions,
+# enums and typedefs. Instead of the function name you must write the name
+# of the declaration;  the struct/union/enum/typedef must always precede
+# the name. Nesting of declarations is not supported.
+# Use the argument mechanism to document members or constants.
+# e.g.
+# /**
+#  * struct my_struct - short description
+#  * @a: first member
+#  * @b: second member
+#  *
+#  * Longer description
+#  */
+# struct my_struct {
+#     int a;
+#     int b;
+# /* private: */
+#     int c;
+# };
+#
+# All descriptions can be multiline, except the short function description.
+#
+# You can also add additional sections. When documenting kernel functions you
+# should document the "Context:" of the function, e.g. whether the functions
+# can be called form interrupts. Unlike other sections you can end it with an
+# empty line.
+# Example-sections should contain the string EXAMPLE so that they are marked
+# appropriately in DocBook.
+#
+# Example:
+# /**
+#  * user_function - function that can only be called in user context
+#  * @a: some argument
+#  * Context: !in_interrupt()
+#  *
+#  * Some description
+#  * Example:
+#  *    user_function(22);
+#  */
+# ...
+#
+#
+# All descriptive text is further processed, scanning for the following special
+# patterns, which are highlighted appropriately.
+#
+# 'funcname()' - function
+# '$ENVVAR' - environmental variable
+# '&struct_name' - name of a structure (up to two words including 'struct')
+# '@parameter' - name of a parameter
+# '%CONST' - name of a constant.

- *	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

-# 18/01/2001 - 	Cleanups
-# 		Functions prototyped as foo(void) same as foo()
-# 		Stop eval'ing where we don't need to.
-# -- huggie@earth.li
-
-# 27/06/2001 -  Allowed whitespace after initial "/**" and
-#               allowed comments before function declarations.
-# -- Christian Kreibich <ck@whoop.org>
-
-# Still to do:
-# 	- add perldoc documentation
-# 	- Look more closely at some of the scarier bits :)
-
-# 26/05/2001 - 	Support for separate source and object trees.
-#		Return error code.
-# 		Keith Owens <kaos@ocs.com.au>
-
-# 23/09/2001 - Added support for typedefs, structs, enums and unions
-#              Support for Context section; can be terminated using empty line
-#              Small fixes (like spaces vs. \s in regex)
-# -- Tim Jansen <tim@tjansen.de>
-
-# 25/07/2012 - Added support for HTML5
-# -- Dan Luedtke <mail@danrl.de>
-
-#
-# This will read a 'c' file and scan for embedded comments in the
-# style of gnome comments (+minor extensions - see below).
-#
-
-# Note: This only supports 'c'.
-
-# usage:
-# kernel-doc [ -docbook | -html | -html5 | -text | -man | -list ]
-#            [ -no-doc-sections ]
-#            [ -function funcname [ -function funcname ...] ]
-#            c file(s)s > outputfile
-# or
-#            [ -nofunction funcname [ -function funcname ...] ]
-#            c file(s)s > outputfile
-#
-#  Set output format using one of -docbook -html -html5 -text or -man.
-#  Default is man.
-#  The -list format is for internal use by docproc.
-#
-#  -no-doc-sections
-#	Do not output DOC: sections
-#
-#  -function funcname
-#	If set, then only generate documentation for the given function(s) or
-#	DOC: section titles.  All other functions and DOC: sections are ignored.
-#
-#  -nofunction funcname
-#	If set, then only generate documentation for the other function(s)/DOC:
-#	sections. Cannot be used together with -function (yes, that's a bug --
-#	perl hackers can fix it 8))
-#
-#  c files - list of 'c' files to process
-#
-#  All output goes to stdout, with errors to stderr.
-
-#
-# format of comments.
-# In the following table, (...)? signifies optional structure.
-#                         (...)* signifies 0 or more structure elements
-# /**
-#  * function_name(:)? (- short description)?
-# (* @parameterx: (description of parameter x)?)*
-# (* a blank line)?
-#  * (Description:)? (Description of function)?
-#  * (section header: (section description)? )*
-#  (*)?*/
-#
-# So .. the trivial example would be:
-#
-# /**
-#  * my_function
-#  */
-#
-# If the Description: header tag is omitted, then there must be a blank line
-# after the last parameter specification.
-# e.g.
-# /**
-#  * my_function - does my stuff
-#  * @my_arg: its mine damnit
-#  *
-#  * Does my stuff explained.
-#  */
-#
-#  or, could also use:
-# /**
-#  * my_function - does my stuff
-#  * @my_arg: its mine damnit
-#  * Description: Does my stuff explained.
-#  */
-# etc.
-#
-# Besides functions you can also write documentation for structs, unions,
-# enums and typedefs. Instead of the function name you must write the name
-# of the declaration;  the struct/union/enum/typedef must always precede
-# the name. Nesting of declarations is not supported.
-# Use the argument mechanism to document members or constants.
-# e.g.
-# /**
-#  * struct my_struct - short description
-#  * @a: first member
-#  * @b: second member
-#  *
-#  * Longer description
-#  */
-# struct my_struct {
-#     int a;
-#     int b;
-# /* private: */
-#     int c;
-# };
-#
-# All descriptions can be multiline, except the short function description.
-#
-# You can also add additional sections. When documenting kernel functions you
-# should document the "Context:" of the function, e.g. whether the functions
-# can be called form interrupts. Unlike other sections you can end it with an
-# empty line.
-# Example-sections should contain the string EXAMPLE so that they are marked
-# appropriately in DocBook.
-#
-# Example:
-# /**
-#  * user_function - function that can only be called in user context
-#  * @a: some argument
-#  * Context: !in_interrupt()
-#  *
-#  * Some description
-#  * Example:
-#  *    user_function(22);
-#  */
-# ...
-#
-#
-# All descriptive text is further processed, scanning for the following special
-# patterns, which are highlighted appropriately.
-#
-# 'funcname()' - function
-# '$ENVVAR' - environmental variable
-# '&struct_name' - name of a structure (up to two words including 'struct')
-# '@parameter' - name of a parameter
-# '%CONST' - name of a constant.
