The cpufreq core is already validating the CPU frequency table after
calling the ->init() callback of the cpufreq drivers and the drivers
don't need to do the same anymore. Though they need to set the
policy->freq_table field directly from the ->init() callback now.

Stop validating the frequency table from SCMI driver.

When multiple CPUs are related in one cpufreq policy, the first online
CPU will be chosen by default to handle cpufreq operations. Let's take
cpu0 and cpu1 as an example.

When cpu0 is offline, policy->cpu will be shifted to cpu1. cpu1's perf
capabilities should be initialized. Otherwise, perf capabilities are 0s
and speed change can not take effect.

This patch copies perf capabilities of the first online CPU to other
shared CPUs when policy shared type is CPUFREQ_SHARED_TYPE_ANY.

Pull ARM SoC driver updates from Arnd Bergmann:
 "The main addition this time around is the new ARM "SCMI" framework,
  which is the latest in a series of standards coming from ARM to do
  power management in a platform independent way.

  This has been through many review cycles, and it relies on a rather
  interesting way of using the mailbox subsystem, but in the end I
  agreed that Sudeep's version was the best we could do after all.

  Other changes include:

   - the ARM CCN driver is moved out of drivers/bus into drivers/perf,
     which makes more sense. Similarly, the performance monitoring
     portion of the CCI driver are moved the same way and cleaned up a
     little more.

   - a series of updates to the SCPI framework

   - support for the Mediatek mt7623a SoC in drivers/soc

   - support for additional NVIDIA Tegra hardware in drivers/soc

   - a new reset driver for Socionext Uniphier

   - lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and
     drivers/firmware and drivers/reset across platforms"

Pull ARM SoC platform updates from Arnd Bergmann:
 "This release brings up a new platform based on the old ARM9 core: the
  Nuvoton NPCM is used as a baseboard management controller, competing
  with the better known ASpeed AST2xx series.

  Another important change is the addition of ARMv7-A based chips in
  mach-stm32. The older parts in this platform are ARMv7-M based
  microcontrollers, now they are expanding to general-purpose workloads.

  The other changes are the usual defconfig updates to enable additional
  drivers, lesser bugfixes. The largest updates as often are the ongoing
  OMAP cleanups, but we also have a number of changes for the older PXA
  and davinci platforms this time.

  For the Renesas shmobile/r-car platform, some new infrastructure is
  needed to make the watchdog work correctly.

  Supporting Multiprocessing on Allwinner A80 required a significant
  amount of new code, but is not doing anything unexpected"

Pull ARM SoC device tree updates from Arnd Bergmann:
 "This is the usual set of changes for device trees, with over 700
  non-merged changesets. There is an ongoing set of dtc warning fixes
  and the usual bugfixes, cleanups and added device support.

  The most interesting bit as usual is support for new machines listed
  below:

   - The Allwinner H6 makes its debut with the Pine-H64 board, and we
     get two new machines based on its older siblings: the H5 based
     OrangePi Zero+ and the A64 based Teres-I Laptop from Olimex. On the
     32-bit side, we add The Olimex som204 based on Allwinner A20, and
     the Banana Pi M2 Zero development board (based on H2).

   - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
     development board and p2888 CPU module.

   - The Nuvoton npcm750 is a BMC that was newly added, for now we only
     support running on the evaluation board.

   - STmicroelectronics stm32 gains support for the stm32mp157c and two
     evaluation boards.

   - The Toradex Colibri board family grows a few members based on the
     i.MX6ULL variant.

   - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6 family
     of chips.

   - The Phytec phyBOARD Mira is a family of industrial boards based on
     i.MX6. For now, four models get added.

   - TI am335x based PDU-001 is an industrial embedded machine used for
     traffic monitoring

   - The Aspeed platform now supports running on the BMC on the Qualcomm
     Centriq 2400 server

   - Samsung Exynos4 based Galaxy S3 is a family of mobile phones
     Qualcomm msm8974 based Galaxy S5 is a rather different phone made
     by the same company.

   - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
     for the various boards made by Xilinx themselves, as well as the
     Digilent Zybo Z7.

   - The ARM Versatile family now supports the "IB2" interface board.

   - The Renesas H2 based "Stout" and the H3 based Salvator-X are more
     evaluation boards named after a kind of beer, as most of them are.
     The r8a77980 (V3H) based "Condor" apparently doesn't follow that
     tradition. ;-)

   - ROC-RK3328-CC is a simple developement board from the Libre
     Computer Project, based on the Rockchips RK3328 SoC

   - Haiku is another development board plus Qseven module based on
     Rockchips RK3368 and made by Theobroma Systems"

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace

Pull siginfo updates from Eric Biederman:
 "The work on cleaning up and getting the bugs out of siginfo generation
  was largely stalled this round. The progress that was made was the
  definition of FPE_FLTUNK. Which is usable to fix many of the cases
  where siginfo generation is erroneously generating SI_USER by setting
  si_code to 0, that has recently been tagged as FPE_FIXME.

  You already have the change by way of the arm64 tree as that
  definition was pulled into the arm64 tree to allow fixing the problem
  there.

  What remains is the second round of fixing for what I thought was a
  trivial change to the struct siginfo when put the union in _sigfault
  where it belongs. Do to historical reasons 32bit m68k only ensures
  that pointers are 2 byte aligned. So I have added a m68k test case
  made of BUILD_BUG_ONs to verify I have this fix correct and possibly
  catch problems, and I have computed the number of bytes of padding
  needed for the _addr_bnd and _addr_pkey cases and just use an array of
  characters that size.

  For pure paranoia I have written the code so if there is an
  architecture out there that does not perform any alignment of
  structures it should still work.

  With the removal of all of the stale arechitectures this cycle future
  work on cleaning up struct siginfo should be much easier. Almost all
  of the conflicting si_code definitions have been removed with the
  removal of (blackfin, tile, and frv). Plus some of the most difficult
  to test cases have simply been removed from the tree.

  Which means that with a little luck copy_siginfo_to_user can become a
  light weight wrapper around copy_to_user in the next cycle"

 "In this round, we've mainly focused on performance tuning and critical
  bug fixes occurred in low-end devices. Sheng Yong introduced
  lost_found feature to keep missing files during recovery instead of
  thrashing them. We're preparing coming fsverity implementation. And,
  we've got more features to communicate with users for better
  performance. In low-end devices, some memory-related issues were
  fixed, and subtle race condtions and corner cases were addressed as
  well.

  Enhancements:
   - large nat bitmaps for more free node ids
   - add three block allocation policies to pass down write hints given by user
   - expose extension list to user and introduce hot file extension
   - tune small devices seamlessly for low-end devices
   - set readdir_ra by default
   - give more resources under gc_urgent mode regarding to discard and cleaning
   - introduce fsync_mode to enforce posix or not
   - nowait aio support
   - add lost_found feature to keep dangling inodes
   - reserve bits for future fsverity feature
   - add test_dummy_encryption for FBE

  Bug fixes:
   - don't use highmem for dentry pages
   - align memory boundary for bitops
   - truncate preallocated blocks in write errors
   - guarantee i_times on fsync call
   - clear CP_TRIMMED_FLAG correctly
   - prevent node chain loop during recovery
   - avoid data race between atomic write and background cleaning
   - avoid unnecessary selinux violation warnings on resgid option

In the effort to remove all VLAs from the kernel[1], it is desirable to
build with -Wvla.  However, this warning is overly pessimistic, in that
it is only happy with stack array sizes that are declared as constant
expressions, and not constant values.  One case of this is the
evaluation of the max() macro which, due to its construction, ends up
converting constant expression arguments into a constant value result.

All attempts to rewrite this macro with __builtin_constant_p() failed
with older compilers (e.g.  gcc 4.4)[2].  However, Martin Uecker,
constructed[3] a mind-shattering solution that works everywhere.
Cthulhu fhtagn!

This patch updates the min()/max() macros to evaluate to a constant
expression when called on constant expression arguments.  This removes
several false-positive stack VLA warnings from an x86 allmodconfig build
when -Wvla is added:

  $ diff -u before.txt after.txt | grep ^-
  -drivers/input/touchscreen/cyttsp4_core.c:871:2: warning: ISO C90 forbids variable length array ‘ids’ [-Wvla]
  -fs/btrfs/tree-checker.c:344:4: warning: ISO C90 forbids variable length array ‘namebuf’ [-Wvla]
  -lib/vsprintf.c:747:2: warning: ISO C90 forbids variable length array ‘sym’ [-Wvla]
  -net/ipv4/proc.c:403:2: warning: ISO C90 forbids variable length array ‘buff’ [-Wvla]
  -net/ipv6/proc.c:198:2: warning: ISO C90 forbids variable length array ‘buff’ [-Wvla]
  -net/ipv6/proc.c:218:2: warning: ISO C90 forbids variable length array ‘buff64’ [-Wvla]

This also updates two cases where different enums were being compared
and explicitly casts them to int (which matches the old side-effect of
the single-evaluation code): one in tpm/tpm_tis_core.h, and one in
drm/drm_color_mgmt.c.

Pull sound updates from Takashi Iwai:
 "This became a large update. The changes are scattered widely, and the
  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"

Pull GPIO updates from Linus Walleij:
 "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"
