      Pull user namespaces work from Eric Biederman:
       "The work to convert the kernel to use kuid_t and kgid_t has been
        finished since 3.12 so it is time to remove the scaffolding that
        allowed the work to progress incrementally.
      
        The first patch on this branch just removes the scaffolding, ensuring
        we will always get compile errors if people accidentally try the
        userspace and the kernel uid and gid types.  The second patch an
        overlooked and unused chunk of mips code that that fails to build
        after the first patch.
      
        The code hasn't been in linux-next for long (as I was out of it and
        could not sheppared the cold properly) but the patch has been around
        for a long time just waiting for the day when I had finished the
        uid/gid conversions.  Putting the code in linux-next did find the
        compile failure on mips so I took the time to get that fix reviewed
        and included.  Beyond that I am not too worried about errors because
        all these two patches do is delete a modest amount of code"

      Pull thermal management updates from Zhang Rui:
       "This time, the biggest change is the work of representing hardware
        thermal properties in device tree infrastructure.
      
        This work includes the introduction of a device tree bindings for
        describing the hardware thermal behavior and limits, and also a parser
        to read and interpret the data, and build thermal zones and thermal
        binding parameters.  It also contains three examples on how to use the
        new representation on sensor devices, using three different drivers to
        accomplish it.  One driver is in thermal subsystem, the TI SoC
        thermal, and the other two drivers are in hwmon subsystem.
      
        Actually, this would be the first step of the complete work because we
        still need to check other potential drivers to be converted and then
        validate the proposed API.  But the reason why I include it in this
        pull request is that, first, this change does not hurt any others
        without using this approach, second, the principle and concept of this
        change would not break after converting the remaining drivers.  BTW,
        as you can see, there are several points in this change that do not
        belong to thermal subsystem.  Because it has been suggested by Guenter
        R that in such cases, it is recommended to send the complete series
        via one single subsystem.
      
        Specifics:
      
         - representing hardware thermal properties in device tree
           infrastructure
      
         - fix a regression that the imx thermal driver breaks system suspend.
      
         - introduce ACPI INT3403 thermal driver to retrieve temperature data
           from the INT3403 ACPI device object present on some systems.
      
         - introduce debug statement for thermal core and step_wise governor.
      
         - assorted fixes and cleanups for thermal core, cpu cooling, exynos
           thrmal, intel powerclamp and imx thermal driver"

      Merge tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm · 09da8dfa
      Linus Torvalds authored
      Pull ACPI and power management updates from Rafael Wysocki:
       "As far as the number of commits goes, the top spot belongs to ACPI
        this time with cpufreq in the second position and a handful of PM
        core, PNP and cpuidle updates.  They are fixes and cleanups mostly, as
        usual, with a couple of new features in the mix.
      
        The most visible change is probably that we will create struct
        acpi_device objects (visible in sysfs) for all devices represented in
        the ACPI tables regardless of their status and there will be a new
        sysfs attribute under those objects allowing user space to check that
        status via _STA.
      
        Consequently, ACPI device eject or generally hot-removal will not
        delete those objects, unless the table containing the corresponding
        namespace nodes is unloaded, which is extremely rare.  Also ACPI
        container hotplug will be handled quite a bit differently and cpufreq
        will support CPU boost ("turbo") generically and not only in the
        acpi-cpufreq driver.
      
        Specifics:
      
         - ACPI core changes to make it create a struct acpi_device object for
           every device represented in the ACPI tables during all namespace
           scans regardless of the current status of that device.  In
           accordance with this, ACPI hotplug operations will not delete those
           objects, unless the underlying ACPI tables go away.
      
         - On top of the above, new sysfs attribute for ACPI device objects
           allowing user space to check device status by triggering the
           execution of _STA for its ACPI object.  From Srinivas Pandruvada.
      
         - ACPI core hotplug changes reducing code duplication, integrating
           the PCI root hotplug with the core and reworking container hotplug.
      
         - ACPI core simplifications making it use ACPI_COMPANION() in the
           code "glueing" ACPI device objects to "physical" devices.
      
         - ACPICA update to upstream version 20131218.  This adds support for
           the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves
           debug facilities.  From Bob Moore, Lv Zheng and Betty Dall.
      
         - Init code change to carry out the early ACPI initialization
           earlier.  That should allow us to use ACPI during the timekeeping
           initialization and possibly to simplify the EFI initialization too.
           From Chun-Yi Lee.
      
         - Clenups of the inclusions of ACPI headers in many places all over
           from Lv Zheng and Rashika Kheria (work in progress).
      
         - New helper for ACPI _DSM execution and rework of the code in
           drivers that uses _DSM to execute it via the new helper.  From
           Jiang Liu.
      
         - New Win8 OSI blacklist entries from Takashi Iwai.
      
         - Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun
           Guo, Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava,
           Rashika Kheria, Tang Chen, Zhang Rui.
      
         - intel_pstate driver updates, including proper Baytrail support,
           from Dirk Brandewie and intel_pstate documentation from Ramkumar
           Ramachandra.
      
         - Generic CPU boost ("turbo") support for cpufreq from Lukasz
           Majewski.
      
         - powernow-k6 cpufreq driver fixes from Mikulas Patocka.
      
         - cpufreq core fixes and cleanups from Viresh Kumar, Jane Li, Mark
           Brown.
      
         - Assorted cpufreq drivers fixes and cleanups from Anson Huang, John
           Tobias, Paul Bolle, Paul Walmsley, Sachin Kamat, Shawn Guo, Viresh
           Kumar.
      
         - cpuidle cleanups from Bartlomiej Zolnierkiewicz.
      
         - Support for hibernation APM events from Bin Shi.
      
         - Hibernation fix to avoid bringing up nonboot CPUs with ACPI EC
           disabled during thaw transitions from Bjørn Mork.
      
         - PM core fixes and cleanups from Ben Dooks, Leonardo Potenza, Ulf

       "Updates of SoC-near drivers and other driver updates that makes more
        sense to take through our tree.
      
        The largest part of this is a conversion of device registration for
        some renesas shmobile/sh devices over to use resources.  This has
        required coordination with the corresponding arch/sh changes, and
        we've agreed to merge the arch/sh changes through our tree.
      
        Added in this branch is support for Trusted Foundations secure
        firmware, which is what is used on many of the commercial Nvidia Tegra
        products that are in the market, including the Nvidia Shield.  The
        code is local to arch/arm at this time since it's uncertain whether it
        will be shared with arm64 longer-term, if needed we will refactor
        later.

      drivers/memstick/host/rtsx_pci_ms.c: fix ms card data transfer bug · 63509bea
      Micky Ching authored
      This patch is used to add support for ms card. The main difference
      between ms card and mspro card is long data transfer mode. mspro card
      can use auto mode DMA for long data transfer, but ms can not use this
      mode, it should use normal mode DMA.
      
      The memstick core added support for ms card, but the original driver will
      make ms card fail at initialization, because it uses auto mode DMA.  This
      patch makes the ms card work properly.

      userns: relax the posix_acl_valid() checks · 949b9c3d
      Andreas Gruenbacher authored
      So far, POSIX ACLs are using a canonical representation that keeps all ACL
      entries in a strict order; the ACL_USER and ACL_GROUP entries for specific
      users and groups are ordered by user and group identifier, respectively.
      The user-space code provides ACL entries in this order; the kernel
      verifies that the ACL entry order is correct in posix_acl_valid().
      
      User namespaces allow to arbitrary map user and group identifiers which
      can cause the ACL_USER and ACL_GROUP entry order to differ between user
      space and the kernel; posix_acl_valid() would then fail.
      
      Work around this by allowing ACL_USER and ACL_GROUP entries to be in any
      order in the kernel.  The effect is only minor: file permission checks
      will pick the first matching ACL_USER entry, and check all matching
      ACL_GROUP entries.
      
      (The libacl user-space library and getfacl / setfacl tools will not create
      ACLs with duplicate user or group idenfifiers; they will handle ACLs with
      entries in an arbitrary order correctly.)

      kdump: fix exported size of vmcoreinfo note · 77019967
      Vivek Goyal authored
      Right now we seem to be exporting the max data size contained inside
      vmcoreinfo note.  But this does not include the size of meta data around
      vmcore info data.  Like name of the note and starting and ending elf_note.
      
      I think user space expects total size and that size is put in PT_NOTE elf
      header.  Things seem to be fine so far because we are not using vmcoreinfo
      note to the maximum capacity.  But as it starts filling up, to capacity,
      at some point of time, problem will be visible.
      
      I don't think user space will be broken with this change.  So there is no
      need to introduce vmcoreinfo2.  This change is safe and backward
      compatible.  More explanation on why this change is safe is below.
      
      vmcoreinfo contains information about kernel which user space needs to
      know to do things like filtering.  For example, various kernel config
      options or information about size or offset of some data structures etc.
      All this information is commmunicated to user space with an ELF note
      present in ELF /proc/vmcore file.
      
      Currently vmcoreinfo data size is 4096.  With some elf note meta data
      around it, actual size is 4132 bytes.  But we are using barely 25% of that
      size.  Rest is empty.  So even if we tell user space that size of ELf note
      is 4096 and not 4132, nothing will be broken becase after around 1000
      bytes, everything is zero anyway.
      
      But once we start filling up the note to the capacity, and not report the
      full size of note, bad things will start happening.  Either some data will
      be lost or tools will be confused that they did not fine the zero note at
      the end.
      
      So I think this change is safe and should not break existing tools.
