Pull Kconfig updates from Masahiro Yamada:
"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"

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

file licenses
Add a file to the Documentation directory to describe how file licenses
should be described in all kernel files, using the SPDX identifier, as well
as where all licenses should be in the kernel source tree for people to
refer to (LICENSES/).
Thanks to Kate and Greg for review and editing and Jonas for the
suggestions concerning the meta tags in the licenses files.

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 bb3290d91695 ("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

"A few late-arriving docs updates that have no real reason to wait.
There's a new "Co-Developed-by" tag described by Greg, and a build
enhancement from Willy to generate docs warnings during a kernel build
(but only when additional warnings have been requested in general)"

authors
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.

Pull documentation updates from Jonathan Corbet:
"A relatively calm cycle for the docs tree again.
- The old driver statement has been added to the kernel docs.
- We have a couple of new helper scripts. find-unused-docs.sh from
Sayli Karnic will point out kerneldoc comments that are not actually
used in the documentation. Jani Nikula's
documentation-file-ref-check finds references to non-existing files.
- A new ftrace document from Steve Rostedt.
- Vinod Koul converted the dmaengine docs to RST
Beyond that, it's mostly simple fixes.
This set reaches outside of Documentation/ a bit more than most. In
all cases, the changes are to comment docs, mostly from Randy, in
places where there didn't seem to be anybody better to take them"

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.

Pull Kbuild thin archives updates from Masahiro Yamada:
"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"

IBM Verse is a web UI around Lotus Domino mail servers (much like
the Lotus Notes client talks to Domino servers).
For various reasons, it is not at all suitable for kernel development,
all of which have been raised (repeatedly) internally.

Commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81")
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.

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 c8589d1e9e01 ("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.

Pull drm u pdates from Dave Airlie:
"This is the main drm pull request for v4.12. Apart from two fixes
pulls, everything should have been in drm-next for at least 2 weeks.
The biggest thing in here is AMD released the public headers for their
upcoming VEGA GPUs. These as always are quite a sizeable chunk of
header files. They've also added initial non-display support for those
GPUs, though they aren't available in production yet.
Otherwise it's pretty much normal.
New bridge drivers:
- megachips-stdpxxxx-ge-b850v3-fw LVDS->DP++
- generic LVDS bridge support.
Core:
- Displayport link train failure reporting to userspace
- debugfs interface cleaned up
- subsystem TODO in kerneldoc now
- Extended fbdev support (flipping and vblank wait)
- drm_platform removed
- EDP CRC support in helper
- HF-VSDB SCDC support in EDID parser
- Lots of code cleanups and header extraction

In Documentation/process/4.Coding.rst there were a couple of paragraphs
that spilled over the 80 character line length. This was likely caused
when the document was converted to reStructuredText. Re-flow the
paragraphs and make the document references proper reStructuredText
:ref: links.
This also adds the appropriate reStructuredText file heading to
kernel-parameters.rst as referenced by the kernel-parameters link in
this patch.

A patch documenting how to specify which kernels a particular fix should
be backported to (seemingly) inadvertently added a minus sign after the
kernel version. This particular stable-tag format had never been used
prior to this patch, and was neither present when the patch in question
was first submitted (it was added in v2 without any comment).
Drop the minus sign to avoid any confusion.
Fixes: fdc81b7910ad ("stable_kernel_rules: Add clause about specification of kernel versions to patch.")
