More power management updates for 4.17-rc1

 - Rework the idle loop in order to prevent CPUs from spending too
   much time in shallow idle states by making it stop the scheduler
   tick before putting the CPU into an idle state only if the idle
   duration predicted by the idle governor is long enough.  That
   required the code to be reordered to invoke the idle governor
   before stopping the tick, among other things (Rafael Wysocki,
   Frederic Weisbecker, Arnd Bergmann).

 - Add the missing description of the residency sysfs attribute to
   the cpuidle documentation (Prashanth Prakash).

 - Finalize the cpufreq cleanup moving frequency table validation
   from drivers to the core (Viresh Kumar).

 - Fix a clock leak regression in the armada-37xx cpufreq driver
   (Gregory Clement).

 - Fix the initialization of the CPU performance data structures
   for shared policies in the CPPC cpufreq driver (Shunyong Yang).

 - Clean up the ti-cpufreq, intel_pstate and CPPC cpufreq drivers
   a bit (Viresh Kumar, Rafael Wysocki).

 - Mark the expected switch fall-throughs in the PM QoS core (Gustavo
   Silva).

This is the 3.18.104 stable release

sound fixes for 4.17-rc1

The main purpose of this pull request is a fix for a regression
in the recent PCM OSS emulation code that may lead to RCU stall.
Since syzkaller hits this too often, I send the pull request now
with a minimal collection.  Possibly another pull request may
follow before RC1.

The other fixes here are for USB-audio class 2 and 3 to improve
the parser for the clock descriptors.  These are rather cleanups
but good for security, too.

Last but not least, another included fix is the trivial one to
remove superfluous WARN_ON() that annoyed syzbot.

media updates for v4.17-rc1

This is the 4.16.1 stable release

This is the 4.15.16 stable release

This is the 4.14.33 stable release

This is the 4.9.93 stable release

This is the 4.4.127 stable release

This is the 3.18.103 stable release

DeviceTree updates for 4.17:

- Sync dtc to upstream version v1.4.6-9-gaadd0b65c987. This adds a bunch
  more warnings (hidden behind W=1).

- Build dtc lexer and parser files instead of using shipped versions.

- Rework overlay apply API to take an FDT as input and apply overlays in
  a single step.

- Add a phandle lookup cache. This improves boot time by hundreds of
  msec on systems with large DT.

- Add trivial mcp4017/18/19 potentiometers bindings.

- Remove VLA stack usage in DT code.

sound updates for 4.17-rc1

This became a large update.  The changes are scattered widely,
and majority of them are attributed to ASoC componentization.
The gitk output made me dizzy, but it's slightly better than
London tube.

OK, below are some highlights:

- Continued hardening works in ALSA PCM core; most of the
  existing syzkaller reports should have been covered.

- USB-audio got the initial USB Audio Class 3 support, as well
  as UAC2 jack detection support and more DSD-device support.

- ASoC componentization: finally each individual driver was
  converted to components framework, which is more future-proof
  for further works.  Most of conversations were systematic.

- Lots of fixes for Intel Baytrail / Cherrytrail devices with
  Realtek codecs, typically tablets and small PCs.

- Fixes / cleanups for Samsung Odroid systems

- Cleanups in Freescale SSI driver

- New ASoC drivers:
  * AKM AK4458 and AK5558 codecs
  * A few AMD based machine drivers
  * Intel Kabylake machine drivers
  * Maxim MAX9759 codec
  * Motorola CPCAP codec
  * Socionext Uniphier SoCs
  * TI PCM1789 and TDA7419 codecs

- Retirement of Blackfin drivers along with architecture removal.

This is the bulk of GPIO changes for the v4.17 kernel cycle:

New drivers:

- Nintendo Wii GameCube GPIO, known as "Hollywood"

- Raspberry Pi mailbox service GPIO expander

- Spreadtrum main SC9860 SoC and IEC GPIO controllers.

Improvements:

- Implemented .get_multiple() callback for most of the
  high-performance industrial GPIO cards for the ISA bus.

- ISA GPIO drivers now select the ISA_BUS_API instead of
  depending on it. This is merged with the same pattern
  for all the ISA drivers and some other Kconfig cleanups
  related to this.

Cleanup:

- Delete the TZ1090 GPIO drivers following the deletion of
  this SoC from the ARM tree.

- Move the documentation over to driver-api to conform with
  the rest of the kernel documentation build.

- Continue to make the GPIO drivers include only
  <linux/gpio/driver.h> and not the too broad <linux/gpio.h>
  that we want to get rid of.

- Managed to remove VLA allocation from two drivers pending
  more fixes in this area for the next merge window.

- Misc janitorial fixes.
