Linus Torvalds 562f36ed28 Kconfig updates for v4.16
A pretty big batch of Kconfig updates. I have to mention the lexer
 and parser of Kconfig are now built from real .l and .y sources.
 So, flex and bison are the requirement for building the kernel.
 Both of them (unlike gperf) have been stable for a long time. This
 change has been tested several weeks in linux-next, and I did not
 receive any problem report about this.
 
 Summary:
 
 - Add checks for mistakes, like the choice default is not in
   choice, help is doubled
 
 - Document data structure and complex code
 
 - Fix various memory leaks
 
 - Change Makefile to build lexer and parser instead of using
   pre-generated C files
 
 - Drop 'boolean' keyword, which is equivalent to 'bool'
 
 - Use default 'yy' prefix and remove unneeded Make variables
 
 - Fix gettext() check for xconfig
 
 - Announce that oldnoconfig will be finally removed
 
 - Make 'Selected by:' and 'Implied by' readable in help and
   search result
 
 - Hide silentoldconfig from 'make help' to stop confusing people
 
 - Fix misc things and cleanups

Konstantin Ryabitsev b72dde3869 Documentation/process: kernel maintainer PGP guide
This guide is an adapted version of the more general "Protecting Code
Integrity" guide written and maintained by The Linux Foundation IT for
use with open-source projects. It provides the oft-lacking guidance on
the following topics:

- how to properly protect one's PGP keys to minimize the risks of them
  being stolen and used maliciously to impersonate a kernel developer
- how to configure Git to properly use GnuPG
- when and how to use PGP with Git
- how to verify fellow Linux Kernel developer identities

I believe this document should live with the rest of the documentation
describing proper processes one should follow when participating in
kernel development. Placing it in a wiki on some place like kernel.org
would be insufficient for a number of reasons -- primarily, because only
a relatively small subset of maintainers have accounts on kernel.org,
but also because even those who do rarely remember that such wiki
exists. Keeping it with the rest of in-kernel docs should hopefully give
it more visibility, but also help keep it up-to-date as tools and
processes evolve.

Masahiro Yamada 033dba2ec0 kbuild: prepare to remove C files pre-generated by flex and bison
In Linux build system convention, pre-generated files are version-
controlled with a "_shipped" suffix.  During the kernel building,
they are simply shipped (copied) removing the suffix.

This approach can reduce external tool dependency for the kernel build,
but it is tedious to manually regenerate such artifacts from developers'
point of view.  (We need to do "make REGENERATE_PARSERS=1" every time
we touch real source files such as *.l, *.y)

Some months ago, I sent out RFC patches to run flex, bison, and gperf
during the build.

In the review and test, Linus noticed gperf-3.1 had changed the lookup
function prototype.  Then, the use of gperf in kernel was entirely
removed by commit bb3290d916 ("Remove gperf usage from toolchain").

This time, I tested several versions of flex and bison, and I was not
hit by any compatibility issue except a flaw in flex-2.6.3; if you
generate lexer for dtc and genksyms with flex-2.6.3, you will see
"yywrap redefined" warning.  This was not intentional, but a bug,
fixed by flex-2.6.4.  Otherwise, both flex and bison look fairly
stable for a long time.

This commit prepares some build rules to remove the _shipped files.
Also, document minimal requirement for flex and bison.

Rationale for the minimal version:
The -Wmissing-prototypes option of GCC warns "no previous prototype"
for lexers generated by flex-2.5.34 or older, so I chose 2.5.35 as the
required version for flex.  Flex-2.5.35 was released in 2008.  Bison
looks more stable.  I did not see any problem with bison-2.0, released
in 2004.  I did not test bison-1.x, but bison-2.0 should be old enough.

Tested flex versions:
  2.5.35
  2.5.36
  2.5.37
  2.5.39
  2.6.0
  2.6.1
  2.6.2
  2.6.3   (*)
  2.6.4

 (*) flex-2.6.3 causes "yywrap redefined" warning

Tested bison versions:
  2.0
  2.1
  2.2
  2.3
  2.4
  2.4.1
  2.5.1
  2.6

Sometimes a single patch is the result of multiple authors.  As git only
can have one "author" of a patch, it is still good to properly give
credit to the other developers of a commit.  To address this, document
the "Co-Developed-by:" tag which can be used to show other authors of
the patch.

Note, these other authors must also provide a Signed-off-by: tag as it
is their work that is being submitted here.

Greg Kroah-Hartman 13277782dd Documentation: add Kernel Driver Statement to the kernel
Way back in 2008 we didn't have "robust" in-kernel documentation system,
so the idea of putting something like the kernel driver statement in the
kernel tree wasn't even imagined.  But now that has changed, so add the
old document to the kernel source itself to allow for us to properly
reference it in one canonical place (as the LF wiki keeps moving things
around.)

This also will allow people to add their names to it, as I seem to have
lost the ability to do that by not knowing how to edit things on the
original document.

Linus Torvalds 98ced886dd Kbuild thin archives updates for v4.13
Thin archives migration by Nicholas Piggin.
 
 THIN_ARCHIVES has been available for a while as an optional feature
 only for PowerPC architecture, but we do not need two different
 intermediate-artifact schemes.
 
 Using thin archives instead of conventional incremental linking has
 various advantages:
  - save disk space for builds
  - speed-up building a little
  - fix some link issues (for example, allyesconfig on ARM) due to
    more flexibility for the final linking
  - work better with dead code elimination we are planning
 
 As discussed before, this migration has been done unconditionally
 so that any problems caused by this will show up with "git bisect".
 
 With testing with 0-day and linux-next, some architectures actually
 showed up problems, but they were trivial and all fixed now.

changes one entry of GNU make version in the changes.rst, there's still
one more entry saying that one need version 3.80.  Fix that.

Masahiro Yamada 37d69ee308 docs: bump minimal GNU Make version to 3.81
Since 2014, you can't successfully build kernels with GNU Make version
3.80. Example errors:

  $ git describe
  v4.11
  $ make --version | head -1
  GNU Make 3.80
  $ make defconfig
    HOSTCC  scripts/basic/fixdep
  scripts/Makefile.host:135: *** missing separator.  Stop.
  make: *** [defconfig] Error 2
  $ make ARCH=arm64 help
  arch/arm64/Makefile:43: *** unterminated call to function `warning': missing `)'.  Stop.
  $ make help >/dev/null
  ./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive
  ./Documentation/Makefile.sphinx:31: *** only one `else' per conditional.  Stop.
  make: *** [help] Error 2

The first breakage was introduced by commit c8589d1e9e ("kbuild:
handle multi-objs dependency appropriately").  Since then (i.e. v3.18),
GNU Make 3.80 has not been able to compile the kernel, but nobody has
ever complained aboutt (or noticed) it.

Even GNU Make 3.81 is more than 10 years old.  It would not hurt to
match the documentation with reality instead of fixing makefiles.

when the document was converted to reStructuredText. Re-flow the

This also adds the appropriate reStructuredText file heading to
kernel-parameters.rst as referenced by the kernel-parameters link in
this patch.

Markus Heiser db6ccf23e8 docs-rst: automatically convert Graphviz and SVG images
This patch brings scalable figure, image handling and a concept to
embed *render* markups:

* DOT (http://www.graphviz.org)
* SVG

For image handling use the 'image' replacement::

    .. kernel-image::  svg_image.svg
       :alt:    simple SVG image

For figure handling use the 'figure' replacement::

    .. kernel-figure::  svg_image.svg
       :alt:    simple SVG image

       SVG image example

Embed *render* markups (or languages) like Graphviz's **DOT** is
provided by the *render* directive.::

  .. kernel-render:: DOT
     :alt: foobar digraph
     :caption: Embedded **DOT** (Graphviz) code.

     digraph foo {
      "bar" -> "baz";
     }

The *render* directive is a concept to integrate *render* markups and
languages, yet supported markups:

* DOT: render embedded Graphviz's **DOT**
* SVG: render embedded Scalable Vector Graphics (**SVG**)
