      Pull power management updates from Rafael Wysocki:
       "These add sysadmin documentation for cpuidle, extend the cpuidle
        subsystem somewhat, improve the handling of performance states in the
        generic power domains (genpd) and operating performance points (OPP)
        frameworks, add a new cpufreq driver for Qualcomm SoCs, update some
        other cpufreq drivers, switch over the runtime PM framework to using
        high-res timers for device autosuspend, fix a problem with
        suspend-to-idle on ACPI-based platforms, add system-wide suspend and
        resume handling to the devfreq framework, do some janitorial cleanups
        all over and update some utilities.
      
        Specifics:
      
         - Add sysadmin documentation for cpuidle (Rafael Wysocki).
      
         - Make it possible to specify a cpuidle governor from kernel command
           line, add new cpuidle state sysfs attributes for governor
           evaluation, and improve the "polling" idle state handling (Rafael
           Wysocki).
      
         - Fix the handling of the "required-opps" DT property in the
           operating performance points (OPP) framework, improve the
           integration of it with the generic power domains (genpd) framework,
           improve the handling of performance states in them and clean up the
           idle states vs performance states separation in genpd (Viresh
           Kumar, Ulf Hansson).
      
         - Add a cpufreq driver called "qcom-hw" for Qualcomm SoCs using a
           hardware engine to control CPU frequency transitions along with DT
           bindings for it (Taniya Das).
      
         - Fix an intel_pstate driver issue related to CPU offline and update
           the documentation of it (Srinivas Pandruvada).
      
         - Clean up the imx6q cpufreq driver (Anson Huang).
      
         - Add SPDX license IDs to cpufreq schedutil governor files (Daniel
           Lezcano).
      
         - Switch over the runtime PM framework to using high-res timers for
           device autosuspend to allow the control of it to be more precise
           (Vincent Guittot).
      
         - Disable non-wakeup ACPI GPEs during suspend-to-idle so that they
           don't prevent the system from reaching the target low-power state
           and simplify the suspend-to-idle handling on ACPI platforms without
           full Low-Power S0 Idle (LPS0) support (Rafael Wysocki).
      
         - Add system-wide suspend and resume support to the devfreq framework
           (Lukasz Luba).
      
         - Clean up the SmartReflex adaptive voltage scaling (AVS) driver and
           add an SPDX license ID to it (Nishanth Menon, Uwe Kleine-König,
           Thomas Meyer).
      
         - Get rid of code duplication by using the DEFINE_SHOW_ATTRIBUTE
           macro in some places, fix some DT node refcount leaks, and do some
           other janitorial cleanups (Yangtao Li).
      
         - Update the cpupower, intel_pstate_tracer and turbosat utilities
           (Abhishek Goel, Doug Smythies, Len Brown)"

      Pull sound updates from Takashi Iwai:
       "There are no intensive changes in both ALSA and ASoC core parts while
        rather most of changes are a bunch of driver fixes and updates. A
        large diff pattern appears in ASoC TI part which now merges both OMAP
        and DaVinci stuff, but the rest spreads allover the places.
      
        Note that this pull request includes also some updates for LED trigger
        and platform drivers for mute LEDs, appearing in the diffstat as well.
      
        Some highlights:

         - Preparatory work for merging the audio-graph and audio-graph-scu
           cards
         - A merge of TI OMAP and DaVinci directories, as both product lines
           get merged together. Also including a few architecture changes as
           well.
         - Major cleanups of the Maxim MAX9867 driver
         - Small fixes for tablets & co with Intel BYT/CHT chips
         - Lots of rsnd updates as usual
         - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
           RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx
           I2S controllers
      
        HD-audio:
         - Introduce audio-mute LED trigger for replacing the former hackish
           dynamic binding
         - Huawei WMI hotkey and mute LED support
         - Refactoring of PM code and display power controls
         - Headset button support in the generic jack code
         - A few updates for Tegra
         - Fixups for HP EliteBook and ASUS UX391UA
         - Lots of updates for Intel ASoC HD-audio, including the improved DSP
           detection and the fallback binding from ASoC SST to legacy HD-audio
           controller drivers
      
        Others:
         - Updates for FireWire TASCAM and Fireface devices, some other fixes

      Revert "vfs: Allow userns root to call mknod on owned filesystems." · 94f82008
      Christian Brauner authored
      This reverts commit 55956b59.
      
      commit 55956b59 ("vfs: Allow userns root to call mknod on owned filesystems.")
      enabled mknod() in user namespaces for userns root if CAP_MKNOD is
      available. However, these device nodes are useless since any filesystem
      mounted from a non-initial user namespace will set the SB_I_NODEV flag on
      the filesystem. Now, when a device node s created in a non-initial user
      namespace a call to open() on said device node will fail due to:
      
      bool may_open_dev(const struct path *path)
      {
              return !(path->mnt->mnt_flags & MNT_NODEV) &&
                      !(path->mnt->mnt_sb->s_iflags & SB_I_NODEV);
      }
      
      The problem with this is that as of the aforementioned commit mknod()
      creates partially functional device nodes in non-initial user namespaces.
      In particular, it has the consequence that as of the aforementioned commit
      open() will be more privileged with respect to device nodes than mknod().
      Before it was the other way around. Specifically, if mknod() succeeded
      then it was transparent for any userspace application that a fatal error
      must have occured when open() failed.
      
      All of this breaks multiple userspace workloads and a widespread assumption
      about how to handle mknod(). Basically, all container runtimes and systemd
      live by the slogan "ask for forgiveness not permission" when running user
      namespace workloads. For mknod() the assumption is that if the syscall
      succeeds the device nodes are useable irrespective of whether it succeeds
      in a non-initial user namespace or not. This logic was chosen explicitly
      to allow for the glorious day when mknod() will actually be able to create
      fully functional device nodes in user namespaces.
      A specific problem people are already running into when running 4.18 rc
      kernels are failing systemd services. For any distro that is run in a
      container systemd services started with the PrivateDevices= property set
      will fail to start since the device nodes in question cannot be
      opened (cf. the arguments in [1]).
      
      Full disclosure, Seth made the very sound argument that it is already
      possible to end up with partially functional device nodes. Any filesystem
      mounted with MS_NODEV set will allow mknod() to succeed but will not allow
      open() to succeed. The difference to the case here is that the MS_NODEV
      case is transparent to userspace since it is an explicitly set mount option
      while the SB_I_NODEV case is an implicit property enforced by the kernel
      and hence opaque to userspace.

      The reason is we do not pass the Head to page_hstate(), and so, the call
      to compound_order() in page_hstate() returns 0, so we end up checking
      all hstates's size to match PAGE_SIZE.
      
      Obviously, we do not find any hstate matching that size, and we return
      NULL.  Then, we dereference that NULL pointer in
      hugepage_migration_supported() and we got the #PF from above.
      
      Fix that by getting the head page before calling page_hstate().
      
      Also, since gigantic pages span several pageblocks, re-adjust the logic
      for skipping pages.  While are it, we can also get rid of the
      round_up().

      fork,memcg: fix crash in free_thread_stack on memcg charge fail · 5eed6f1d
      Rik van Riel authored
      Commit 9b6f7e16 ("mm: rework memcg kernel stack accounting") will
      result in fork failing if allocating a kernel stack for a task in
      dup_task_struct exceeds the kernel memory allowance for that cgroup.
      
      Unfortunately, it also results in a crash.
      
      This is due to the code jumping to free_stack and calling
      free_thread_stack when the memcg kernel stack charge fails, but without
      tsk->stack pointing at the freshly allocated stack.
      
      This in turn results in the vfree_atomic in free_thread_stack oopsing

      mm: thp: fix flags for pmd migration when split · 2e83ee1d
      Peter Xu authored
      When splitting a huge migrating PMD, we'll transfer all the existing PMD
      bits and apply them again onto the small PTEs.  However we are fetching
      the bits unconditionally via pmd_soft_dirty(), pmd_write() or
      pmd_yound() while actually they don't make sense at all when it's a
      migration entry.  Fix them up.  Since at it, drop the ifdef together as
      not needed.
      
      Note that if my understanding is correct about the problem then if
      without the patch there is chance to lose some of the dirty bits in the
      migrating pmd pages (on x86_64 we're fetching bit 11 which is part of
      swap offset instead of bit 2) and it could potentially corrupt the
      memory of an userspace program which depends on the dirty bit.

      mm, memory_hotplug: initialize struct pages for the full memory section · 2830bf6f
      Mikhail Zaslonko authored
      If memory end is not aligned with the sparse memory section boundary,
      the mapping of such a section is only partly initialized.  This may lead
      to VM_BUG_ON due to uninitialized struct page access from
      is_mem_section_removable() or test_pages_in_a_zone() function triggered

      auxdisplay: charlcd: fix x/y command parsing · 9bc30ab8
      Mans Rullgard authored
      The x/y command parsing has been broken since commit 12995706
      ("staging: panel: Fixed checkpatch warning about simple_strtoul()").
      
      Commit b34050fa
      
       ("auxdisplay: charlcd: Fix and clean up handling of
      x/y commands") fixed some problems by rewriting the parsing code,
      but also broke things further by removing the check for a complete
      command before attempting to parse it.  As a result, parsing is
      terminated at the first x or y character.
      
      This reinstates the check for a final semicolon.  Whereas the original
      code use strchr(), this is wasteful seeing as the semicolon is always
      at the end of the buffer.  Thus check this character directly instead.

      serial/sunsu: fix refcount leak · d430aff8
      Yangtao Li authored
      
      
      The function of_find_node_by_path() acquires a reference to the node
      returned by it and that reference needs to be dropped by its caller.
      
      su_get_type() doesn't do that. The match node are used as an identifier
      to compare against the current node, so we can directly drop the refcount
      after getting the node from the path as it is not used as pointer.
      
      Fix this by use a single variable and drop the refcount right after
      of_find_node_by_path().

      Prevent overflow of sk_msg in sk_msg_clone() · 5c1e7e94
      Vakul Garg authored
      Fixed function sk_msg_clone() to prevent overflow of 'dst' while adding
      pages in scatterlist entries. The overflow of 'dst' causes crash in kernel
      tls module while doing record encryption.
      
      Crash fixed by this patch.

      packet: validate address length · 99137b78
      Willem de Bruijn authored
      
      
      Packet sockets with SOCK_DGRAM may pass an address for use in
      dev_hard_header. Ensure that it is of sufficient length.

      Linus Torvalds authored
      Pull GPIO fixes from Linus Walleij:
       "Hopefully last round of GPIO fixes.
      
        The ACPI patch is pretty important for some laptop users, the rest is
        driver-specific for embedded (mostly ARM) systems.
      
        I took out one ACPI patch that wasn't critical enough because I
        couldn't justify sending it at this point, and that is why the commit
        date is today, but the patches have been in linux-next.
      
        Sorry for not sending some of them earlier :(
      
        Notice that we have a co-maintainer for GPIO now, Bartosz Golaszewski,
        and he might jump in and make some pull requests at times when I am
        off.
      
        Summary:
      
         - ACPI IRQ request deferral
      
         - OMAP: revert deferred wakeup quirk
      
         - MAX7301: fix DMA safe memory handling
      
         - MVEBU: selective probe failure on missing clk"
