      Pull libnvdimm and dax updates from Dan Williams:
       "Save for a few late fixes, all of these commits have shipped in -next
        releases since before the merge window opened, and 0day has given a
        build success notification.
      
        The ext4 touches came from Jan, and the xfs touches have Darrick's
        reviewed-by. An xfstest for the MAP_SYNC feature has been through
        a few round of reviews and is on track to be merged.
      
         - Introduce MAP_SYNC and MAP_SHARED_VALIDATE, a mechanism to enable
           'userspace flush' of persistent memory updates via filesystem-dax
           mappings. It arranges for any filesystem metadata updates that may
           be required to satisfy a write fault to also be flushed ("on disk")
           before the kernel returns to userspace from the fault handler.
           Effectively every write-fault that dirties metadata completes an
           fsync() before returning from the fault handler. The new
           MAP_SHARED_VALIDATE mapping type guarantees that the MAP_SYNC flag
           is validated as supported by the filesystem's ->mmap() file
           operation.
      
         - Add support for the standard ACPI 6.2 label access methods that
           replace the NVDIMM_FAMILY_INTEL (vendor specific) label methods.
           This enables interoperability with environments that only implement
           the standardized methods.
      
         - Add support for the ACPI 6.2 NVDIMM media error injection methods.
      
         - Add support for the NVDIMM_FAMILY_INTEL v1.6 DIMM commands for
           latch last shutdown status, firmware update, SMART error injection,
           and SMART alarm threshold control.
      
         - Cleanup physical address information disclosures to be root-only.
      
         - Fix revalidation of the DIMM "locked label area" status to support
           dynamic unlock of the label area.
      
         - Expand unit test infrastructure to mock the ACPI 6.2 Translate SPA
           (system-physical-address) command and error injection commands.

      Pull rdma maintainership update from Doug Ledford:
       "Add Jason Gunthorpe as co-maintainer of the RDMA stack.
      
        The change is simply to add Jason Gunthorpe to the MAINTAINERS file
        for the RDMA stack (and update him in the .mailmap). Jason and I have
        talked offline, and Jason will be filing a ticket with the k.o
        helpdesk to get an account on k.o, and then we will likely move the
        rdma tree to an area where we can both access it and use a shared repo
        + individual topic branches + merged up for-next branch as the staging
        basis for each release.
      
        Timing here is nice because in the US we are headed into a holiday
        period whereas Jason will be around to keep the patch flow progressing

      Pull ARM SoC driver updates from Arnd Bergmann:
       "This branch contains platform-related driver updates for ARM and
        ARM64, these are the areas that bring the changes:

         - power management support for Amlogic GX

         - the usual updates for reset controller drivers from Philipp Zabel,
           with five added drivers for SoCs in the arc, meson, socfpa,
           uniphier and mediatek families
      
         - updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla,

         - the Freescale/NXP DPAA QBMan drivers from PowerPC can now work on
           ARM as well
      
         - several changes for power management on Broadcom SoCs
      
         - various improvements on Qualcomm, Broadcom, Amlogic, Atmel,

        because the R8A77970 driver is missing a header file that came from
        that pull.
      
        The fact that this got merged afterwards only fixes it at this point,

           chips meant for managed gigabit ethernet switches, based around a
           Cortex-A9 CPU.

      dm bufio: fix integer overflow when limiting maximum cache size · 74d4108d
      Eric Biggers authored
      The default max_cache_size_bytes for dm-bufio is meant to be the lesser
      of 25% of the size of the vmalloc area and 2% of the size of lowmem.
      However, on 32-bit systems the intermediate result in the expression
      
          (VMALLOC_END - VMALLOC_START) * DM_BUFIO_VMALLOC_PERCENT / 100
      
      overflows, causing the wrong result to be computed.  For example, on a
      32-bit system where the vmalloc area is 520093696 bytes, the result is
      1174405 rather than the expected 130023424, which makes the maximum
      cache size much too small (far less than 2% of lowmem).  This causes
      severe performance problems for dm-verity users on affected systems.
      
      Fix this by using mult_frac() to correctly multiply by a percentage.  Do
      this for all places in dm-bufio that multiply by a percentage.  Also
      replace (VMALLOC_END - VMALLOC_START) with VMALLOC_TOTAL, which contrary
      to the comment is now defined in include/linux/vmalloc.h.

      The DM target's 'discards_supported' flag is intended to act as an

      dm: discard support requires all targets in a table support discards · 8a74d29d
      Mike Snitzer authored
      
      
      A DM device with a mix of discard capabilities (due to some underlying
      devices not having discard support) _should_ just return -EOPNOTSUPP for
      the region of the device that doesn't support discards (even if only by
      way of the underlying driver formally not supporting discards).  BUT,
      that does ask the underlying driver to handle something that it never
      advertised support for.  In doing so we're exposing users to the
      potential for a underlying disk driver hanging if/when a discard is
      issued a the device that is incapable and never claimed to support
      discards.
      
      Fix this by requiring that each DM target in a DM table provide discard
      support as a prereq for a DM device to advertise support for discards.
      
      This may cause some configurations that were happily supporting discards
      (even in the face of a mix of discard support) to stop supporting
      discards -- but the risk of users hitting driver hangs, and forced
      reboots, outweighs supporting those fringe mixed discard
      configurations.

      dm mpath: remove annoying message of 'blk_get_request() returned -11' · 9dc112e2
      Ming Lei authored
      It is very normal to see allocation failure, especially with blk-mq
      request_queues, so it's unnecessary to report this error and annoy
      people.
      
      In practice this 'blk_get_request() returned -11' error gets logged
      quite frequently when a blk-mq DM multipath device sees heavy IO.
      
      This change is marked for stable@ because the annoying message in
      question was included in stable@ commit 7083abbb.
      
      Fixes: 7083abbb

      Pull powerpc updates from Michael Ellerman:
       "A bit of a small release, I suspect in part due to me travelling for
        KS. But my backlog of patches to review is smaller than usual, so I
        think in part folks just didn't send as much this cycle.
      
        Non-highlights:
      
         - Five fixes for the >128T address space handling, both to fix bugs
           in our implementation and to bring the semantics exactly into line
           with x86.
      
        Highlights:
      
         - Support for a new OPAL call on bare metal machines which gives us a
           true NMI (ie. is not masked by MSR[EE]=0) for debugging etc.
      
         - Support for Power9 DD2 in the CXL driver.
      
         - Improvements to machine check handling so that uncorrectable errors
           can be reported into the generic memory_failure() machinery.
      
         - Some fixes and improvements for VPHN, which is used under PowerVM
           to notify the Linux partition of topology changes.
      
         - Plumbing to enable TM (transactional memory) without suspend on
           some Power9 processors (PPC_FEATURE2_HTM_NO_SUSPEND).
      
         - Support for emulating vector loads form cache-inhibited memory, on
           some Power9 revisions.
      
         - Disable the fast-endian switch "syscall" by default (behind a
           CONFIG), we believe it has never had any users.
      
         - A major rework of the API drivers use when initiating and waiting
           for long running operations performed by OPAL firmware, and changes
           to the powernv_flash driver to use the new API.
      
         - Several fixes for the handling of FP/VMX/VSX while processes are
           using transactional memory.
      
         - Optimisations of TLB range flushes when using the radix MMU on
           Power9.
      
         - Improvements to the VAS facility used to access coprocessors on
           Power9, and related improvements to the way the NX crypto driver
           handles requests.
      
         - Implementation of PMEM_API and UACCESS_FLUSHCACHE for 64-bit.

      Pull AFS updates from David Howells:
       "kAFS filesystem driver overhaul.
      
        The major points of the overhaul are:
      
         (1) Preliminary groundwork is laid for supporting network-namespacing
             of kAFS. The remainder of the namespacing work requires some way
             to pass namespace information to submounts triggered by an
             automount. This requires something like the mount overhaul that's
             in progress.
      
         (2) sockaddr_rxrpc is used in preference to in_addr for holding
             addresses internally and add support for talking to the YFS VL
             server. With this, kAFS can do everything over IPv6 as well as
             IPv4 if it's talking to servers that support it.
      
         (3) Callback handling is overhauled to be generally passive rather
             than active. 'Callbacks' are promises by the server to tell us
             about data and metadata changes. Callbacks are now checked when
             we next touch an inode rather than actively going and looking for
             it where possible.
      
         (4) File access permit caching is overhauled to store the caching
             information per-inode rather than per-directory, shared over
             subordinate files. Whilst older AFS servers only allow ACLs on
             directories (shared to the files in that directory), newer AFS
             servers break that restriction.
      
             To improve memory usage and to make it easier to do mass-key
             removal, permit combinations are cached and shared.
      
         (5) Cell database management is overhauled to allow lighter locks to
             be used and to make cell records autonomous state machines that
             look after getting their own DNS records and cleaning themselves
             up, in particular preventing races in acquiring and relinquishing
             the fscache token for the cell.
      
         (6) Volume caching is overhauled. The afs_vlocation record is got rid
             of to simplify things and the superblock is now keyed on the cell
             and the numeric volume ID only. The volume record is tied to a
             superblock and normal superblock management is used to mediate
             the lifetime of the volume fscache token.
      
         (7) File server record caching is overhauled to make server records
             independent of cells and volumes. A server can be in multiple
             cells (in such a case, the administrator must make sure that the
             VL services for all cells correctly reflect the volumes shared
             between those cells).
      
             Server records are now indexed using the UUID of the server
             rather than the address since a server can have multiple
             addresses.
      
         (8) File server rotation is overhauled to handle VMOVED, VBUSY (and
             similar), VOFFLINE and VNOVOL indications and to handle rotation
             both of servers and addresses of those servers. The rotation will
             also wait and retry if the server says it is busy.
      
         (9) Data writeback is overhauled. Each inode no longer stores a list
             of modified sections tagged with the key that authorised it in
             favour of noting the modified region of a page in page->private
             and storing a list of keys that made modifications in the inode.
      
             This simplifies things and allows other keys to be used to
             actually write to the server if a key that made a modification
             becomes useless.
      
        (10) Writable mmap() is implemented. This allows a kernel to be build
             entirely on AFS.
      
        Note that Pre AFS-3.4 servers are no longer supported, though this can
        be added back if necessary (AFS-3.4 was released in 1998)"

      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control changes for the v4.15 kernel cycle:
      
        Core:
      
         - The pin control Kconfig entry PINCTRL is now turned into a
           menuconfig option. This obviously has the implication of making the
           subsystem menu visible in menuconfig. This is happening because of
           two things:
      
            (a) Intel have started to deploy and depend on pin controllers in
                a way that is affecting users directly. This happens on the
                highly integrated laptop chipsets named after geographical
                places: baytrail, broxton, cannonlake, cedarfork, cherryview,
                denverton, geminilake, lewisburg, merrifield, sunrisepoint...
                It started a while back and now it is ever more evident that
                this is crucial infrastructure for x86 laptops and not an
                embedded obscurity anymore. Users need to be aware.
      
            (b) Pin control expanders on I2C and SPI that are arch-agnostic.
                Currently Semtech SX150X and Microchip MCP28x08 but more are
                expected. Users will have to be able to configure these in
                directly for their set-up.
      
         - Just go and select GPIOLIB now that we made sure that GPIOLIB is a
           very vanilla subsystem. Do not depend on it, if we need it, select
           it.
      
         - Exposing the pin control subsystem in menuconfig uncovered a bunch
           of obscure bugs that are now hopefully fixed, all more or less
           pertaining to Blackfin.
      
         - Unified namespace for cross-calls between pin control and GPIO.
      
         - New support for clock skew/delay generic DT bindings and generic
           pin config options for this.
      
         - Minor documentation improvements.
      
        Various:
      
         - The Renesas SH-PFC pin controller has evolved a lot. It seems
           Renesas are churning out new SoCs by the minute.
      
         - A bunch of non-critical fixes for the Rockchip driver.
      
         - Improve the use of library functions instead of open coding.
      
         - Support the MCP28018 variant in the MCP28x08 driver.
      
         - Static constifying"
