Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ * "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 <linux/config.h> which then again
+ * includes <linux/autoconf.h>
+ *
+ * If the user re-runs make *config, linux/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 linux/autoconf.h by a dependency on every config
+ * option which is mentioned in any of the listed prequisites.
+ *
+ * To be exact, split-include populates a tree in include/config/,
+ * e.g. include/config/his/driver.h, which contains the #define/#undef
+ * for the CONFIG_HIS_DRIVER option.
+ *
+ * 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 linux/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.

+ * Changed the compression method from stem compression to "table lookup"
+ * compression
+ *
+ * Table compression uses all the unused char codes on the symbols and
+ * maps these to the most used substrings (tokens). For instance, it might
+ * map char code 0xF7 to represent "write_" and then in every symbol where
+ * "write_" appears it can be replaced by 0xF7, saving 5 bytes.
+ * The used codes themselves are also placed in the table so that the
+ * decompresion can work without "special cases".
+ * Applied to kernel symbols, this usually produces a compression ratio
+ * of about 50%.

+"Menus\n"
+"----------\n"
+"o Use the Up/Down arrow keys (cursor keys) to highlight the item\n"

+"$TERM variable set to point to a xterm definition which supports color.\n"
+"Otherwise, Menuconfig will look rather bad. Menuconfig will not\n"
+"display correctly in a RXVT window because rxvt displays only one\n"
+"intensity of color, bright.\n"
+"\n"
+"Menuconfig will display larger menus on screens or xterms which are\n"
+"set to display more than the standard 25 row by 80 column geometry.\n"
+"In order for this to work, the \"stty size\" command must be able to\n"

+"RECOMMEND that you make sure you do NOT have the shell variables\n"
+"LINES and COLUMNS exported into your environment. Some distributions\n"

+# 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>
+
+
+#
+# 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:
+# kerneldoc [ -docbook | -html | -text | -man ]
+# [ -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 -text or -man. Default is man.
+#
+# -function funcname
+# If set, then only generate documentation for the given function(s). All
+# other functions are ignored.
+#
+# -nofunction funcname
+# If set, then only generate documentation for the other function(s). All
+# other functions are ignored. Cannot be used with -function together
+# (yes thats 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 ommitted, 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.
+#
+# Beside 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;
+# };
+#
+# 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

+/*
+ * Changes by Clifford Wolf (god@clifford.at)
+ *
+ * [ 1998-06-13 ]
+ *
+ * *) A bugfix for the Page-Down problem
+ *
+ * *) Formerly when I used Page Down and Page Up, the cursor would be set
+ * to the first position in the menu box. Now lxdialog is a bit
+ * smarter and works more like other menu systems (just have a look at
+ * it).
+ *
+ * *) Formerly if I selected something my scrolling would be broken because
+ * lxdialog is re-invoked by the Menuconfig shell script, can't
+ * remember the last scrolling position, and just sets it so that the
+ * cursor is at the bottom of the box. Now it writes the temporary file
+ * lxdialog.scrltmp which contains this information. The file is
+ * deleted by lxdialog if the user leaves a submenu or enters a new
+ * one, but it would be nice if Menuconfig could make another "rm -f"
+ * just to be sure. Just try it out - you will recognise a difference!
+ *
+ * [ 1998-06-14 ]
+ *
+ * *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
+ * and menus change their size on the fly.
+ *
+ * *) If for some reason the last scrolling position is not saved by
+ * lxdialog, it sets the scrolling so that the selected item is in the
+ * middle of the menu box, not at the bottom.
+ *
+ * 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
+ * Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
+ * This fixes a bug in Menuconfig where using ' ' to descend into menus
+ * would leave mis-synchronized lxdialog.scrltmp files lying around,
+ * fscanf would read in 'scroll', and eventually that value would get used.

+# so the symbols are defined as static unless a particular
+# CONFIG_... requires it to be external.
+#
+# A symbol that is suffixed with '(export only)' has these properties
+#
+# * It is global.
+# * It is marked EXPORT_SYMBOL or EXPORT_SYMBOL_GPL, either in the same
+# source file or a different source file.
+# * Given the current .config, nothing uses the symbol.
+#
+# The symbol is a candidate for conversion to static, plus removal of the
+# export. But be careful that a different .config might use the symbol.

+# Name space analysis and cleanup is an iterative process. You cannot
+# expect to find all the problems in a single pass.
+#
+# * Identify possibly unnecessary global declarations, verify that they
+# really are unnecessary and change them to static.
+# * Compile and fix up gcc warnings about static, removing dead symbols
+# as necessary.
+# * make clean and rebuild with different configs (especially
+# CONFIG_MODULES=n) to see which symbols are being defined when the
+# config does not require them. These symbols bloat the kernel object
+# for no good reason, which is frustrating for embedded systems.
+# * Wrap config sensitive symbols in #ifdef CONFIG_foo, as long as the
+# code does not get too ugly.

+# scripts/patch-kernel . .. -ac
+# Get the latest Linux kernel and patch it with the latest ac patch

+# This is applied using "patch -p1 -s" from within the kernel directory.
+# A check is then made for "*.rej" files to see if the patch was
+# successful. If it is, then all of the "*.orig" files are removed.
