+ * "Optimize" a list of dependencies as spit out by gcc -MD
+ * for the kernel build
+ * ===========================================================================
+ *
+ * Author Kai Germaschewski
+ * Copyright 2002 by Kai Germaschewski <kai.germaschewski@gmx.de>
+ *
+ * This software may be used and distributed according to the terms
+ * of the GNU General Public License, incorporated herein by reference.
+ *
+ *
+ * Introduction:
+ *
+ * gcc produces a very nice and correct list of dependencies which
+ * tells make when to remake a file.
+ *
+ * To use this list as-is however has the drawback that virtually
+ * every file in the kernel includes autoconf.h.
+ *
+ * If the user re-runs make *config, autoconf.h will be
+ * regenerated. make notices that and will rebuild every file which
+ * includes autoconf.h, i.e. basically all files. This is extremely
+ * annoying if the user just changed CONFIG_HIS_DRIVER from n to m.
+ *
+ * So we play the same trick that "mkdep" played before. We replace
+ * the dependency on autoconf.h by a dependency on every config
+ * option which is mentioned in any of the listed prequisites.
+ *
+ * kconfig populates a tree in include/config/ with an empty file
+ * for each config symbol and when the configuration is updated
+ * the files representing changed config options are touched
+ * which then let make pick up the changes and the files that use
+ * the config symbols are rebuilt.
+ *
+ * So if the user changes his CONFIG_HIS_DRIVER option, only the objects
+ * which depend on "include/linux/config/his/driver.h" will be rebuilt,
+ * so most likely only his driver ;-)
+ *
+ * The idea above dates, by the way, back to Michael E Chastain, AFAIK.
+ *
+ * So to get dependencies right, there are two issues:
+ * o if any of the files the compiler read changed, we need to rebuild
+ * o if the command line given to the compile the file changed, we
+ * better rebuild as well.
+ *
+ * The former is handled by using the -MD output, the later by saving
+ * the command line used to compile the old object and comparing it
+ * to the one we would now use.
+ *
+ * Again, also this idea is pretty old and has been discussed on
+ * kbuild-devel a long time ago. I don't have a sensibly working
+ * internet connection right now, so I rather don't mention names
+ * without double checking.
+ *
+ * This code here has been based partially based on mkdep.c, which
+ * says the following about its history:
+ *
+ * Copyright abandoned, Michael Chastain, <mailto:mec@shout.net>.
+ * This is a C version of syncdep.pl by Werner Almesberger.
+ *
+ *
+ * It is invoked as
+ *
+ * fixdep <depfile> <target> <cmdline>
+ *
+ * and will read the dependency file <depfile>
+ *
+ * The transformed dependency snipped is written to stdout.
+ *
+ * It first generates a line
+ *
+ * cmd_<target> = <cmdline>
+ *
+ * and then basically copies the .<target>.d file to stdout, in the
+ * process filtering out the dependency on autoconf.h and adding
+ * dependencies on include/config/my/option.h for every
+ * CONFIG_MY_OPTION encountered in any of the prequisites.
+ *
+ * It will also filter out all the dependencies on *.ver. We need
+ * to make sure that the generated version checksum are globally up
+ * to date before even starting the recursive build, so it's too late
+ * at this point anyway.
+ *
+ * The algorithm to grep for "CONFIG_..." is bit unusual, but should
+ * be fast ;-) We don't even try to really parse the header files, but
+ * merely grep, i.e. if CONFIG_FOO is mentioned in a comment, it will
+ * be picked up as well. It's not a problem with respect to
+ * correctness, since that can only give too many dependencies, thus
+ * we cannot miss a rebuild. Since people tend to not mention totally
+ * unrelated CONFIG_ options all over the place, it's not an
+ * efficiency problem either.
+ *
+ * (Note: it'd be easy to port over the complete mkdep state machine,
+ * but I don't think the added complexity is worth it)
+ */
+/*
+ * Note 2: if somebody writes HELLO_CONFIG_BOOM in a file, it will depend onto
+ * CONFIG_BOOM. This could seem a bug (not too hard to fix), but please do not
+ * fix it! Some UserModeLinux files (look at arch/um/) call CONFIG_BOOM as
+ * UML_CONFIG_BOOM, to avoid conflicts with /usr/include/linux/autoconf.h,
+ * through arch/um/include/uml-config.h; this fixdep "bug" makes sure that
+ * those files will have correct dependencies.

+ * EXPORT_SYMBOL_GPL_FUTURE()
+ * This is used to create proper -function and

+ * 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

+# 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.
+# A non-void function should have a "Return:" section describing the return
+# value(s).
+# 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.
