       "There's not a lot in this - the main addition is the CRC validation of
        the entire region of the log that the will be recovered, along with
        several log recovery fixes.  Most of the rest is small bug fixes and
        cleanups.
      
        I have three bug fixes still pending, all that address recently fixed
        regressions that I will send to next week after they've had some time
        in for-next.
      
        Summary:
         - extensive CRC validation during log recovery
         - several log recovery bug fixes
         - Various DAX support fixes
         - AGFL size calculation fix
         - various cleanups in preparation for new functionality

      Linus Torvalds authored
      Pull libnvdimm updates from Dan Williams:
       "The bulk of this has appeared in -next and independently received a
        build success notification from the kbuild robot.  The 'for-4.5/block-
        dax' topic branch was rebased over the weekend to drop the "block
        device end-of-life" rework that Al would like to see re-implemented
        with a notifier, and to address bug reports against the badblocks
        integration.
      
        There is pending feedback against "libnvdimm: Add a poison list and
        export badblocks" received last week.  Linda identified some localized
        fixups that we will handle incrementally.
      
        Summary:
      
         - Media error handling: The 'badblocks' implementation that
           originated in md-raid is up-levelled to a generic capability of a
           block device.  This initial implementation is limited to being
           consulted in the pmem block-i/o path.  Later, 'badblocks' will be
           consulted when creating dax mappings.
      
         - Raw block device dax: For virtualization and other cases that want
           large contiguous mappings of persistent memory, add the capability
           to dax-mmap a block device directly.
      
         - Increased /dev/mem restrictions: Add an option to treat all
           io-memory as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access
           while a driver is actively using an address range.  This behavior
           is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be
           overridden by the existing "iomem=relaxed" kernel command line
           option.
      
         - Miscellaneous fixes include a 'pfn'-device huge page alignment fix,
           block device shutdown crash fix, and other small libnvdimm fixes"

      Pull second batch of media updates from Mauro Carvalho Chehab:
       "This is the second part of the media patches.  It contains the media
        controller next generation patches, with is the result of one year of
        discussions and development.  It also contains patches to enable media
        controller support at the DVB subsystem.
      
        The goal is to improve the media controller to allow proper support
        for other types of Video4Linux devices (radio and TV ones) and to
        extend the media controller functionality to allow it to be used by
        other subsystems like DVB, ALSA and IIO.
      
        In order to use the new functionality, a new ioctl is needed
        (MEDIA_IOC_G_TOPOLOGY).  As we're still discussing how to pack the
        struct fields of this ioctl in order to avoid compat32 issues, I
        decided to add a patch at the end of this series commenting out the
        new ioctl, in order to postpone the addition of the new ioctl to the
        next Kernel version (4.6).
      
        With that, no userspace visible changes should happen at the media
        controller API, as the existing ioctls are untouched.  Yet, it helps
        DVB, ALSA and IIO developers to develop and test the patches adding
        media controller support there, as the core will contain all required
        internal changes to allow adding support for devices that belong to
        those subsystems"

      Pull MTD updates from Brian Norris:
       "Generic MTD:
      
         - populate the MTD device 'of_node' field (and get a proper 'of_node'
           symlink in sysfs)
      
           This yielded some new helper functions, and changes across a
           variety of drivers
      
         - partitioning cleanups, to prepare for better device-tree based
           partitioning in the future
      
           Eliminate a lot of boilerplate for drivers that want to use
           OF-based partition parsing
      
           The DT bindings for this didn't settle yet, so most non-cleanup
           portions are deferred for a future release
      
        NAND:
      
         - embed a struct mtd_info inside struct nand_chip
      
           This is really long overdue; too many drivers have to do the same
           silly boilerplate to allocate and link up two "independent"
           structs, when in fact, everyone is assuming there is an exact 1:1
           relationship between a NAND chips struct and its underlying MTD.
           This aids improved helpers and should make certain abstractions
           easier in the future.
      
           Also causes a lot of churn, helped along by some automated code
           transformations
      
         - add more core support for detecting (and "correcting") bitflips in
           erased pages; requires opt-in by drivers, but at least we kill a
           few bad implementations and hopefully stave off future ones
      
         - pxa3xx_nand: cleanups, a few fixes, and PM improvements
      
         - new JZ4780 NAND driver
      
        SPI NOR:
      
         - provide default erase function, for controllers that just want to
           send the SECTOR_ERASE command directly
      
         - fix some module auto-loading issues with device tree
           ("jedec,spi-nor")
      
         - error handling fixes
      
         - new Mediatek QSPI flash driver
      
        Other:
      
         - cfi: force valid geometry Kconfig (finally!)
      
           This one used to trip up randconfigs occasionally, since bots
           aren't deterred by big scary "advanced configuration" menus

      efi: include asm/early_ioremap.h not asm/efi.h to get early_memremap · 0f7f2f0c
      Ard Biesheuvel authored
      The code in efi.c uses early_memremap(), but relies on a transitive
      include rather than including asm/early_ioremap.h directly, since
      this header did not exist on ia64.
      
      Commit f7d92489 ("arm64/efi: refactor EFI init and runtime code
      for reuse by 32-bit ARM") attempted to work around this by including
      asm/efi.h, which transitively includes asm/early_ioremap.h on most
      architectures. However, since asm/efi.h does not exist on ia64 either,
      this is not much of an improvement.
      
      Now that we have created an asm/early_ioremap.h for ia64, we can just
      include it directly.

      ia64: split off early_ioremap() declarations into asm/early_ioremap.h · 80926770
      Ard Biesheuvel authored
      Unlike x86, arm64 and ARM, ia64 does not declare its implementations
      of early_ioremap/early_iounmap/early_memremap/early_memunmap in a header
      file called <asm/early_ioremap.h>
      
      This complicates the use of these functions in generic code, since the
      header cannot be included directly, and we have to rely on transitive
      includes, which is fragile.
      
      So create a <asm/early_ioremap.h> for ia64, and move the existing
      definitions into it.

      Linus Torvalds authored
      Pull oower management and ACPI updates from Rafael Wysocki:
       "As far as the number of commits goes, ACPICA takes the lead this time,
        followed by cpufreq and the device properties framework changes.
      
        The most significant new feature is the debugfs-based interface to the
        ACPICA's AML debugger added in the previous cycle and a new user space
        tool for accessing it.
      
        On the cpufreq front, the core is updated to handle governors more
        efficiently, particularly on systems where a single cpufreq policy
        object is shared between multiple CPUs, and there are quite a few
        changes in drivers (intel_pstate, cpufreq-dt etc).
      
        The device properties framework is updated to handle built-in (ie
        included in the kernel itself) device properties better, among other
        things by adding a fallback mechanism that will allow drivers to
        provide default properties to be used in case the plaform firmware
        doesn't provide the properties expected by them.
      
        The Operating Performance Points (OPP) framework gets new DT bindings
        and debugfs support.
      
        A new cpufreq driver for ST platforms is added and the ACPI driver for
        AMD SoCs will now support the APM X-Gene ACPI I2C device.
      
        The rest is mostly fixes and cleanups all over.
      
        Specifics:
      
         - Add a debugfs-based interface for interacting with the ACPICA's AML
           debugger introduced in the previous cycle and a new user space tool
           for that, fix some bugs related to the AML debugger and clean up
           the code in question (Lv Zheng, Dan Carpenter, Colin Ian King,
           Markus Elfring).
      
         - Update ACPICA to upstream revision 20151218 including a number of
           fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe
           Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael
           Wysocki).
      
           In particular, the previously added erroneous support for the _SUB
           object is dropped, the concatenate operator will support all ACPI
           objects now, the Debug Object handling is improved, the SuperName
           handling of parameters being control methods is fixed, the
           ObjectType operator handling is updated to follow ACPI 5.0A and the
           handling of CondRefOf and RefOf is updated accordingly, module-
           level code will be executed after loading each ACPI table now
           (instead of being run once after all tables containing AML have
           been loaded), the Operation Region handlers management is updated
           to fix some reported problems and a the ACPICA code in the kernel
           is more in line with the upstream now.
      
         - Update the ACPI backlight driver to provide information on whether
           or not it will generate key-presses for brightness change hotkeys
           and update some platform drivers (dell-wmi, thinkpad_acpi) to use
           that information to avoid sending double key-events to users pace
           for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu,
           Adrien Schildknecht).
      
         - Improve the ACPI handling of interrupt GPIOs (Christophe Ricard).
      
         - Fix the handling of the list of device IDs of device objects found
           in the ACPI namespace and add a helper for checking if there is a
           device object for a given device ID (Lukas Wunner).
      
         - Change the logic in the ACPI namespace scanning code to create
           struct acpi_device objects for all ACPI device objects found in the
           namespace even if _STA fails for them which helps to avoid device
           enumeration problems on Microsoft Surface 3 (Aaron Lu).
      
         - Add support for the APM X-Gene ACPI I2C device to the ACPI driver
           for AMD SoCs (Loc Ho).
      
         - Fix the long-standing issue with the DMA controller on Intel SoCs
           where ACPI tables have no power management support for the DMA
           controller itself, but it can be powered off automatically when the
           last (other) device on the SoC is powered off via ACPI and clean up
           the ACPI driver for Intel SoCs (acpi-lpss) after previous attempts
           to fix that problem (Andy Shevchenko).
      
         - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King,
           Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki,
           Sinan Kaya).
      
         - Update the device properties framework for better handling of
           built-in properties, add support for built-in properties to the
           platform bus type, update the MFD subsystem's handling of device
           properties and add support for passing default configuration data
           as device properties to the intel-lpss MFD drivers, convert the
           designware I2C driver to use the unified device properties API and
           add a fallback mechanism for using default built-in properties if
           the platform firmware fails to provide the properties as expected
           by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus,
           Andrew Morton).
      
         - Add new Device Tree bindings to the Operating Performance Points
           (OPP) framework and update the exynos4412 DT binding accordingly,
           introduce debugfs support for the OPP framework (Viresh Kumar,
           Bartlomiej Zolnierkiewicz).
      
         - Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng
           Chen).
      
         - Update the cpufreq core to make the handling of governors more
           efficient, especially on systems where policy objects are shared
           between multiple CPUs (Viresh Kumar, Rafael Wysocki).
      
         - Fix cpufreq governor handling on configurations with
           CONFIG_HZ_PERIODIC set (Chen Yu).
      
         - Clean up the cpufreq core code related to the boost sysfs knob
           support and update the ACPI cpufreq driver accordingly (Rafael
           Wysocki).
      
         - Add a new cpufreq driver for ST platforms and corresponding Device
           Tree bindings (Lee Jones).
      
         - Update the intel_pstate driver to allow the P-state selection
           algorithm used by it to depend on the CPU ID of the processor it is
           running on, make it use a special P-state selection algorithm (with
           an IO wait time compensation tweak) on Atom CPUs based on the
           Airmont and Silvermont cores so as to reduce their energy
           consumption and improve intel_pstate documentation (Philippe
           Longepe, Srinivas Pandruvada).
      
         - Update the cpufreq-dt driver to support registering cooling devices
           that use the (P * V^2 * f) dynamic power draw formula where V is
           the voltage, f is the frequency and P is a constant coefficient
           provided by Device Tree and update the arm_big_little cpufreq
           driver to use that support (Punit Agrawal).
      
         - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq,
           blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob
           Tanenbaum, Markus Elfring).
      
         - cpuidle core tweaks related to polling and measured_us calculation
           (Rik van Riel).
      
         - Removal of modularity from a few cpuidle drivers (clps711x, ux500,
           exynos) that cannot be built as modules in practice (Paul
           Gortmaker).
      
         - PM core update to prevent devices from being probed during system
           suspend/resume which is generally problematic and may lead to
           inconsistent behavior (Grygorii Strashko).
      
         - Assorted updates of the PM core and related code (Julia Lawall,
           Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki, Ulf
           Hansson).
      
         - PNP bus type updates (Christophe Le Roy, Heiner Kallweit).
      
         - PCI PM code cleanups (Jarkko Nikula, Julia Lawall).
      
         - cpupower tool updates (Jacob Tanenbaum, Thomas Renninger)"

      Pull cgroup updates from Tejun Heo:
      
       - cgroup v2 interface is now official.  It's no longer hidden behind a
         devel flag and can be mounted using the new cgroup2 fs type.
      
         Unfortunately, cpu v2 interface hasn't made it yet due to the
         discussion around in-process hierarchical resource distribution and
         only memory and io controllers can be used on the v2 interface at the
         moment.
      
       - The existing documentation which has always been a bit of mess is
         relocated under Documentation/cgroup-v1/. Documentation/cgroup-v2.txt
         is added as the authoritative documentation for the v2 interface.
      
       - Some features are added through for-4.5-ancestor-test branch to
         enable netfilter xt_cgroup match to use cgroup v2 paths.  The actual
         netfilter changes will be merged through the net tree which pulled in
         the said branch.
      
       - Various cleanups
      
      * 'for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
        cgroup: rename cgroup documentations
