Pull media documentation updates from Mauro Carvalho Chehab:
"This patch series does the conversion of all media documentation stuff
to Restrutured Text markup format and add them to the
Documentation/index.rst file.The media documentation was grouped into 4 books:
- media uAPI
- media kAPI
- V4L driver-specific documentation
- DVB driver-specific documentationIt also contains several documentation improvements and one fixup
patch for a core issue with cropcap.PS. After this patch series, the media DocBook is deprecated and
should be removed. I'll add such patch on a future pull request"* tag 'media/v4.8-4' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (322 commits)

Several build configurations had already disabled this warning because
it generates a lot of false positives. But some had not, and it was
still enabled for "allmodconfig" builds, for example.Looking at the warnings produced, every single one I looked at was a
false positive, and the warnings are frequent enough (and big enough)
that they can easily hide real problems that you don't notice in the
noise generated by -Wmaybe-uninitialized.The warning is good in theory, but this is a classic case of a warning
that causes more problems than the warning can solve.If gcc gets better at avoiding false positives, we may be able to
re-enable this warning. But as is, we're better off without it, and I
want to be able to see the *real* warnings.Signed-off-by: Linus Torvalds

Pull power management updates from Rafael Wysocki:
"Again, the majority of changes go into the cpufreq subsystem, but
there are no big features this time. The cpufreq changes that stand
out somewhat are the governor interface rework and improvements
related to the handling of frequency tables. Apart from those, there
are fixes and new device/CPU IDs in drivers, cleanups and an
improvement of the new schedutil governor.Next, there are some changes in the hibernation core, including a fix
for a nasty problem related to the MONITOR/MWAIT usage by CPU offline
during resume from hibernation, a few core improvements related to
memory management during resume, a couple of additional debug features
and cleanups.Finally, we have some fixes and cleanups in the devfreq subsystem,
generic power domains framework improvements related to system
suspend/resume, support for some new chips in intel_idle and in the
power capping RAPL driver, a new version of the AnalyzeSuspend utility
and some assorted fixes and cleanups.Specifics:
- Rework the cpufreq governor interface to make it more
straightforward and modify the conservative governor to avoid using
transition notifications (Rafael Wysocki).- Rework the handling of frequency tables by the cpufreq core to make
it more efficient (Viresh Kumar).- Modify the schedutil governor to reduce the number of wakeups it
causes to occur in cases when the CPU frequency doesn't need to be
changed (Steve Muckle, Viresh Kumar).- Fix some minor issues and clean up code in the cpufreq core and
governors (Rafael Wysocki, Viresh Kumar).- Add Intel Broxton support to the intel_pstate driver (Srinivas
Pandruvada).- Fix problems related to the config TDP feature and to the validity
of the MSR_HWP_INTERRUPT register in intel_pstate (Jan Kiszka,
Srinivas Pandruvada).- Make intel_pstate update the cpu_frequency tracepoint even if the
frequency doesn't change to avoid confusing powertop (Rafael
Wysocki).- Clean up the usage of __init/__initdata in intel_pstate, mark some
of its internal variables as __read_mostly and drop an unused
structure element from it (Jisheng Zhang, Carsten Emde).- Clean up the usage of some duplicate MSR symbols in intel_pstate
and turbostat (Srinivas Pandruvada).- Update/fix the powernv, s3c24xx and mvebu cpufreq drivers (Akshay
Adiga, Viresh Kumar, Ben Dooks).- Fix a regression (introduced during the 4.5 cycle) in the
pcc-cpufreq driver by reverting the problematic commit (Andreas
Herrmann).- Add support for Intel Denverton to intel_idle, clean up Broxton
support in it and make it explicitly non-modular (Jacob Pan, Jan
Beulich, Paul Gortmaker).- Add support for Denverton and Ivy Bridge server to the Intel RAPL
power capping driver and make it more careful about the handing of
MSRs that may not be present (Jacob Pan, Xiaolong Wang).- Fix resume from hibernation on x86-64 by making the CPU offline
during resume avoid using MONITOR/MWAIT in the "play dead" loop
which may lead to an inadvertent "revival" of a "dead" CPU and a
page fault leading to a kernel crash from it (Rafael Wysocki).- Make memory management during resume from hibernation more
straightforward (Rafael Wysocki).- Add debug features that should help to detect problems related to
hibernation and resume from it (Rafael Wysocki, Chen Yu).- Clean up hibernation core somewhat (Rafael Wysocki).
- Prevent KASAN from instrumenting the hibernation core which leads
to large numbers of false-positives from it (James Morse).- Prevent PM (hibernate and suspend) notifiers from being called
during the cleanup phase if they have not been called during the
corresponding preparation phase which is possible if one of the
other notifiers returns an error at that time (Lianwei Wang).- Improve suspend-related debug printout in the tasks freezer and
clean up suspend-related console handling (Roger Lu, Borislav
Petkov).- Update the AnalyzeSuspend script in the kernel sources to version
4.2 (Todd Brandt).- Modify the generic power domains framework to make it handle system
suspend/resume better (Ulf Hansson).- Make the runtime PM framework avoid resuming devices synchronously
when user space changes the runtime PM settings for them and
improve its error reporting (Rafael Wysocki, Linus Walleij).- Fix error paths in devfreq drivers (exynos, exynos-ppmu,
exynos-bus) and in the core, make some devfreq code explicitly
non-modular and change some of it into tristate (Bartlomiej
Zolnierkiewicz, Peter Chen, Paul Gortmaker).- Add DT support to the generic PM clocks management code and make it
export some more symbols (Jon Hunter, Paul Gortmaker).- Make the PCI PM core code slightly more robust against possible
driver errors (Andy Shevchenko).- Make it possible to change DESTDIR and PREFIX in turbostat (Andy
Shevchenko)"* tag 'pm-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (89 commits)

Pull documentation updates from Jonathan Corbet:
"Some big changes this month, headlined by the addition of a new
formatted documentation mechanism based on the Sphinx system.The objectives here are to make it easier to create better-integrated
(and more attractive) documents while (eventually) dumping our
one-of-a-kind, cobbled-together system for something that is widely
used and maintained by others. There's a fair amount of information
what's being done, why, and how to use it in:https://lwn.net/Articles/692704/
https://lwn.net/Articles/692705/Closer to home, Documentation/kernel-documentation.rst describes how
it works.For now, the new system exists alongside the old one; you should soon
see the GPU documentation converted over in the DRM pull and some
significant media conversion work as well. Once all the docs have
been moved over and we're convinced that the rough edges (of which are
are a few) have been smoothed over, the DocBook-based stuff should go
away.Primary credit is to Jani Nikula for doing the heavy lifting to make
this stuff actually work; there has also been notable effort from
Markus Heiser, Daniel Vetter, and Mauro Carvalho Chehab.Expect a couple of conflicts on the new index.rst file over the course
of the merge window; they are trivially resolvable. That file may be
a bit of a conflict magnet in the short term, but I don't expect that
situation to last for any real length of time.Beyond that, of course, we have the usual collection of tweaks,
updates, and typo fixes"* tag 'docs-for-linus' of git://git.lwn.net/linux: (77 commits)

When a header file is removed from generic-y (often accompanied by the
addition of an arch specific header), the generated wrapper file will
persist, and in some cases may still take precedence over the new arch
header.For example commit f1fe2d21f4e1 ("MIPS: Add definitions for extended
context") removed ucontext.h from generic-y in arch/mips/include/asm/,
and added an arch/mips/include/uapi/asm/ucontext.h. The continued use of
the wrapper when reusing a dirty build tree resulted in build failures
in arch/mips/kernel/signal.c:arch/mips/kernel/signal.c: In function ‘sc_to_extcontext’:
arch/mips/kernel/signal.c:142:12: error: ‘struct ucontext’ has no member named ‘uc_extcontext’
return &uc->uc_extcontext;
^
Fix by detecting and removing wrapper headers in generated header
directories that do not correspond to a filename in generic-y, genhdr-y,

Scan all input files for EXPORT_SYMBOLs along with the explicitly
specified export files before actually parsing anything.Signed-off-by: Jani Nikula
-
If the kernel-doc comments for functions are not in the same file as the
EXPORT_SYMBOL statements, the -export and -internal output selections do
not work as expected. This is typically the case when the kernel-doc
comments are in header files next to the function declarations and the
EXPORT_SYMBOL statements are next to the function definitions in the
source files.Let the user specify additional source files in which to look for the
EXPORT_SYMBOLs using the new -export-file FILE option, which may be
given multiple times.The pathological example for this is include/net/mac80211.h, which has
all the kernel-doc documentation for the exported functions defined in a
plethora of source files net/mac80211/*.c.Signed-off-by: Jani Nikula

commit 32217761ee9db0215350dfe1ca4e66f312fb8c54
Author: Jani Nikula
Date: Sun May 29 09:40:44 2016 +0300kernel-doc: concatenate contents of colliding sections
we started getting (more) errors on duplicate section names, especially
on the default section name "Description":include/net/mac80211.h:3174: warning: duplicate section name 'Description'
This is usually caused by a slightly unorthodox placement of parameter
descriptions, like in the above case, and kernel-doc resetting back to
the default section more than once within a kernel-doc comment.Ignore warnings on the duplicate section name automatically assigned by
kernel-doc, and only consider explicitly user assigned duplicate section
names an issue.Signed-off-by: Jani Nikula

Lots of kerneldoc entries use "example:" or "note:" as section headers.
Until such a time as we can make them use proper markup, make them work as
intended.Signed-off-by: Jonathan Corbet

Because of an improper dereference, a stray 'C' character was output to
the modalias when no 'compatible' was specified. This is the case for
some old PowerMac drivers which only set the 'name' property. Fix it to
let them match again.Reported-by: Mathieu Malaterre

Opt-in since this wreaks the rst output and must be removed
by consumers again. This is useful to adjust the linenumbers
for included kernel-doc snippets in shinx. With that sphinx
error message will be accurate when there's issues with the
rst-ness of the kernel-doc comments.Especially when transitioning a new docbook .tmpl to .rst this
is extremely useful, since you can just use your editors compilation
quickfix list to accurately jump from error to error.v2:
- Also make sure that we filter the LINENO for purpose/at declaration
start so it only shows for selected blocks, not all of them (Jani).
While at it make it a notch more accurate.
- Avoid undefined $lineno issues. I tried filtering these out at the
callsite, but Jani spotted more when linting the entire kernel.
Unamed unions and similar things aren't stored consistently and end
up with an undefined line number (but also no kernel-doc text, just
the parameter type). Simplify things and filter undefined line
numbers in print_lineno() to catch them all.v3: Fix LINENO 0 issue for kernel-doc comments without @param: lines
or any other special sections that directly jump to the description
after the "name - purpose" line. Only really possible for functions
without parameters. Noticed by Jani.Cc: Jani Nikula
