      Pull ARM SoC DT updates from Kevin Hilman:
       "As usual, quite a few device-tree updates in ARM land.  There was one
        minor churn in DTs due to relicensing under a dual-license, and lots
        of little additions of new peripherals, features etc, but nothing
        really exciting to call to your attention.  Some higlights, focsuing
        on support for new SoCs and boards:

      Pull sound updates from Takashi Iwai:
       "It was a busy development cycle at this time, as you can see a wide
        range of changes in diffstat.  There are no big changes but many
        refactoring and improvements.  Here we go some highlights:
      
        ALSA core:
         - Procfs codes were cleaned up to use seq_file
         - Procfs can be opt out via Kconfig (only for EXPERT)
         - Two types of jack API were unified finally; now both kctl and input
           jack devs are handled via a single function call.
      
        HD-audio:
         - Continued code restructuring for the future ASoC driver; now HDA
           controller driver is split to a core helper module.
         - Preliminary codes for Skylake audio support in HDA core.
         - Proper i915 gfx power well management for SKL & co
         - Enabled runtime PM as default for Intel HDMI/DP codecs
         - Newer Tegra chip supports
         - More quirks for Dell headsets, Alienware (with CA0132), etc.
         - A couple of DRM ELD helper API functions
      
        ASoC:
         - Support for loading ASoC topology maps from firmware, intended to
           be used to allow self-describing DSP firmware images to be built
           which can map controls added by the DSP to userspace without the
           kernel needing to know about individual DSP firmwares
         - Lots of refactoring to avoid direct access to snd_soc_codec where
           it's not needed supporting future refactoring
         - Big refactoring, cleanup and enhancement for the Wolfson ADSP
           driver
         - Cleanup series for TI TAS2552 and R-CAR drivers
         - Fixes and improvements on RT56xx codecs
         - Support for TI TAS571x power amplifiers
         - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs
         - Support for x86 systems with RT5650 and Qualcomm Storm
         - Support for Mediatek AFE (Audio Front End) unit
         - Other various small fixes to ASoC codec drivers
      
        Firewire:
         - Enhanced to allow non-blocking streams to use timestamp
           synchronization
         - Improve support for DM1500 and BeBoBv3
      
        Misc:
         - Cleanup of old pci API functions over all PCI sound drivers
         - Fix long-standing regression of the old powermac i2c setup"

      coredump: add __printf attribute to cn_*printf functions · b4176b7c

      coredump: use from_kuid/kgid when formatting corename · 5202efe5
      Nicolas Iooss authored
      When adding __printf attribute to cn_printf, gcc reports some issues:
      
        fs/coredump.c:213:5: warning: format '%d' expects argument of type
        'int', but argument 3 has type 'kuid_t' [-Wformat=]
             err = cn_printf(cn, "%d", cred->uid);
             ^
        fs/coredump.c:217:5: warning: format '%d' expects argument of type
        'int', but argument 3 has type 'kgid_t' [-Wformat=]
             err = cn_printf(cn, "%d", cred->gid);
             ^
      
      These warnings come from the fact that the value of uid/gid needs to be
      extracted from the kuid_t/kgid_t structure before being used as an
      integer.  More precisely, cred->uid and cred->gid need to be converted to
      either user-namespace uid/gid or to init_user_ns uid/gid.
      
      Use init_user_ns in order not to break existing ABI, and document this in
      Documentation/sysctl/kernel.txt.
      
      While at it, format uid and gid values with %u instead of %d because
      uid_t/__kernel_uid32_t and gid_t/__kernel_gid32_t are unsigned int.

      NILFS2: support NFSv2 export · f73c2f1f
      NeilBrown authored
      The "fh_len" passed to ->fh_to_* is not guaranteed to be that same as that
      returned by encode_fh - it may be larger.
      
      With NFSv2, the filehandle is fixed length, so it may appear longer than
      expected and be zero-padded.
      
      So we must test that fh_len is at least some value, not exactly equal to
      it.

      only once.
      
      Standardize the NOTE: <...> form to always emit a blank
      line before the NOTE and always use print << "EOM" style.

      checkpatch: categorize some long line length checks · 47e0c88b
      Joe Perches authored
      Many lines of code extend beyond the maximum line length.  Some of these
      are possibly justified by use type.
      
      For instance:
      
      structure definitions where comments are added per member like:
      struct foo {
      	type member;		/* some long description */
      
      And lines that don't fit the typical logging message style
      where a string constant is used like:
      
              SOME_MACRO(args, "Some long string");
      
      Categorize these long line types so that checkpatch can use a command-line
      --ignore=<type> option to avoid emitting some long line warnings.
      
      One of the existing checkpatch exclusions allowed kernel-doc argument
      documentation to exceed 80 columns because old versions of kernel-doc
      required single line documentation.  The requirement was removed in 2009
      so remove that exclusion.
      
      Add documentation to make the test a bit clearer.

      checkpatch: use $String consistently · 33acb54a
      Joe Perches authored
      String detection where a source line with a string constant is converted
      can either have an X or a space.
      
      Some of the string detection regexes do not allow the space character, but
      there is a handy $String variable that does.
      
      Convert the remaining uses of string detection regexes to use the $String
      variable to reduce possible false negatives.

      checkpatch: make types found in a source file/patch local · 485ff23e
      Alex Dowad authored
      checkpatch uses various cues in its input patches and files to discover
      the names of user-defined types and modifiers.  It then uses that
      information when processing expressions to discover potential style
      issues.
      
      Unfortunately, in rare cases, this means that checkpatch may give
      different results if you run it on several input files in one execution,
      or one by one!
      
      The reason is that it may identify a type (or something that looks like a
      type) in one file, and then carry this information over when processing a
      different file.
      
      For example, drivers/staging/media/bcm2048/radio-bcm2048.c contains this
      line (in a macro):
      
      	size value;
      
      and drivers/staging/media/davinci_vpfe/vpfe_video.c has this line:
      
      	while (size * *nbuffers > vpfe_dev->video_limit)
      
      If checkpatch processes these 2 files in a single command like:
      	./scripts/checkpatch.pl -f $file1 $file2
      the (spurious) "size" type detected in the first file will cause it to flag
      the second file for improper use of the pointer dereference operator.
      
      To fix this, store types and modifiers found in a file in separate arrays
      from built-in ones, and reset the arrays of types and modifiers found in
      files at the beginning of each new source file.

      checkpatch: add --strict warning for c99 fixed size typedefs : int<size>_t · e6176fa4
      Joe Perches authored
      Using declarations like u_int16_t in kernel code is not preferred.
      
      Suggest the kernel sized types instead of the c99 types when not in the
      uapi directory.
      
      Add a $typeC99Typedefs variable for the types to check and neaten the
      other typedef variables.

      checkpatch: check for uncommented waitqueue_active() · cb426e99
      Joe Perches authored
      Linus sayeth:
      
      : Pretty much every single time people use this "if
      : (waitqueue_active())" model, it tends to be a bug, because it means
      : that there is zero serialization with people who are just about to go
      : to sleep. It's fundamentally racy against all the "wait_event()" loops
      : that carefully do memory barriers between testing conditions and going
      : to sleep, because the memory barriers now don't exist on the waking
      : side.
      :
      : So I'm making a new rule: if you use waitqueue_active(), I want an
      : explanation for why it's not racy with the waiter. A big comment about
      : the memory ordering, or about higher-level locks that are held by the
      : caller, or something.
