Linus Torvalds bb2407a721 There's been a fair amount of activity in Documentation/ this time around:
- Lots of work aligning Documentation/ABI with reality, done by Aishwarya
    Pant.
 
  - The trace documentation has been converted to RST by Changbin Du
 
  - I thrashed up kernel-doc to deal with a parsing issue and to try to make
    the code more readable.  It's still a 20+-year-old Perl hack, though.
 
  - Lots of other updates, typo fixes, and more.

Nicholas Piggin f49821ee32 kbuild: rename built-in.o to built-in.a
Incremental linking is gone, so rename built-in.o to built-in.a, which
is the usual extension for archive files.

This patch does two things, first is a simple search/replace:

git grep -l 'built-in\.o' | xargs sed -i 's/built-in\.o/built-in\.a/g'

The second is to invert nesting of nested text manipulations to avoid
filtering built-in.a out from libs-y2:

-libs-y2 := $(filter-out %.a, $(patsubst %/, %/built-in.a, $(libs-y)))
+libs-y2 := $(patsubst %/, %/built-in.a, $(filter-out %.a, $(libs-y)))

Dominik Brodowski 819671ff84 syscalls: define and explain goal to not call syscalls in the kernel
The syscall entry points to the kernel defined by SYSCALL_DEFINEx()
and COMPAT_SYSCALL_DEFINEx() should only be called from userspace
through kernel entry points, but not from the kernel itself. This
will allow cleanups and optimizations to the entry paths *and* to
the parts of the kernel code which currently need to pretend to be
userspace in order to make use of syscalls.

Mauro Carvalho Chehab 88de995ccf COPYING: create a new file with points to the Kernel license files
With the addition of SPDX patchset, the contents of COPYING file
is now duplicated at two other files under LICENSE:
	LICENSES/preferred/GPL-2.0
	LICENSES/exceptions/Linux-syscall-note

It is easy to check that the contents of the licence written on
those files are identical with COPYING using:

	$ diff -upr COPYING LICENSES/preferred/GPL-2.0
	$ diff -upr COPYING LICENSES/exceptions/Linux-syscall-note|less

Also, a new file was added, with describes how SPDX should work at
the Kernel source files:
	Documentation/process/license-rules.rst

Instead fo having it copying the contents of two files, and not
even mentioning the third one, replace it by a file whose content
points to the other tree files, preserving the Kernel's license.

Adjust license-rules.rst accordingly.

Please notice that this file preserves the Kernel license as
is, without any changes.

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.

Linus Torvalds 255442c938 Documentation updates for 4.16. New stuff includes refcount_t
documentation, errseq documentation, kernel-doc support for nested
 structure definitions, the removal of lots of crufty kernel-doc support for
 unused formats, SPDX tag documentation, the beginnings of a manual for
 subsystem maintainers, and lots of fixes and updates.
 
 As usual, some of the changesets reach outside of Documentation/ to effect
 kerneldoc comment fixes.  It also adds the new LICENSES directory, of which
 Thomas promises I do not need to be the maintainer.

Merge tag 'docs-4.16' of git://git.lwn.net/linux

Pull documentation updates from Jonathan Corbet:
 "Documentation updates for 4.16.

  New stuff includes refcount_t documentation, errseq documentation,
  kernel-doc support for nested structure definitions, the removal of
  lots of crufty kernel-doc support for unused formats, SPDX tag
  documentation, the beginnings of a manual for subsystem maintainers,
  and lots of fixes and updates.

  As usual, some of the changesets reach outside of Documentation/ to
  effect kerneldoc comment fixes. It also adds the new LICENSES
  directory, of which Thomas promises I do not need to be the
  maintainer"

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.

Junio C Hamano d4306db189 Documentation/process: phrasofix
Devils in the details are found only when the high level design is
refined and gets more detailed, and the appropriate phrase to use to
describe this is "problems are revealed", not "problems are
reviewed".

Reviews may reveal these problems, though ;-)

Junio C Hamano d19b3e3237 Documentation/process: fix the canonical patch format description
There shouldn't be a blank line at the beginning, if there is no
optional in-body "From" line.  There must be a blank line between
the body of the explanation and the beginning of the S-o-b lines.
