         that happened to also reflect a changing working set (which required
         old blocks be demoted before the new working set could be promoted)

      Merge tag 'libnvdimm-for-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm · 53ef7d0e
      Linus Torvalds authored
      Pull libnvdimm updates from Dan Williams:
       "The bulk of this has been in multiple -next releases. There were a few
        late breaking fixes and small features that got added in the last
        couple days, but the whole set has received a build success
        notification from the kbuild robot.
      
        Change summary:
      
         - Region media error reporting: A libnvdimm region device is the
           parent to one or more namespaces. To date, media errors have been
           reported via the "badblocks" attribute attached to pmem block
           devices for namespaces in "raw" or "memory" mode. Given that
           namespaces can be in "device-dax" or "btt-sector" mode this new
           interface reports media errors generically, i.e. independent of
           namespace modes or state.
      
           This subsequently allows userspace tooling to craft "ACPI 6.1
           Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error"
           requests and submit them via the ioctl path for NVDIMM root bus
           devices.
      
         - Introduce 'struct dax_device' and 'struct dax_operations': Prompted
           by a request from Linus and feedback from Christoph this allows for
           dax capable drivers to publish their own custom dax operations.
           This fixes the broken assumption that all dax operations are
           related to a persistent memory device, and makes it easier for
           other architectures and platforms to add customized persistent
           memory support.
      
         - 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is
           available for storage appliance applications to manually trigger
           memory controllers to drain write-pending buffers that would
           otherwise be flushed automatically by the platform ADR
           (asynchronous-DRAM-refresh) mechanism at a power loss event.
           Support for "locked" DIMMs is included to prevent namespaces from
           surfacing when the namespace label data area is locked. Finally,
           fixes for various reported deadlocks and crashes, also tagged for
           -stable.
      
         - ACPI / nfit driver updates: General updates of the nfit driver to
           add DSM command overrides, ACPI 6.1 health state flags support, DSM
           payload debug available by default, and various fixes.

      Pull staging/IIO updates from Greg KH:
       "Here is the big staging tree update for 4.12-rc1.
      
        It's a big one, adding about 350k new lines of crap^Wcode, mostly all
        in a big dump of media drivers from Intel. But there's other new
        drivers in here as well, yet-another-wifi driver, new IIO drivers, and
        a new crypto accelerator.
      
        We also deleted a bunch of stuff, mostly in patch cleanups, but also
        the Android ION code has shrunk a lot, and the Android low memory
        killer driver was finally deleted, much to the celebration of the -mm
        developers.
      
        All of these have been in linux-next with a few build issues that will
        show up when you merge to your tree"

      Linus Torvalds authored
      Pull GFS2 updates from Bob Peterson:
       "We've got ten GFS2 patches for this merge window.
      
         - Andreas Gruenbacher wrote a patch to replace the deprecated call to
           rhashtable_walk_init with rhashtable_walk_enter.
      
         - Andreas also wrote a patch to eliminate redundant code in two of
           our debugfs sequence files.
      
         - Andreas also cleaned up the rhashtable key ugliness Linus pointed
           out during this cycle, following Linus's suggestions.
      
         - Andreas also wrote a patch to take advantage of his new function
           rhashtable_lookup_get_insert_fast. This makes glock lookup faster
           and more bullet-proof.
      
         - Andreas also wrote a patch to revert a patch in the evict path that
           caused occasional deadlocks, and is no longer needed.
      
         - Andrew Price wrote a patch to re-enable fallocate for the rindex
           system file to enable gfs2_grow to grow properly on secondary file
           system grow operations.
      
         - I wrote a patch to initialize an inode number field to make certain
           kernel trace points more understandable.
      
         - I also wrote a patch that makes GFS2 file system "withdraw" work
           more like it should by ignoring operations after a withdraw that
           would formerly cause a BUG() and kernel panic.
      
         - I also reworked the entire truncate/delete algorithm, scrapping the
           old recursive algorithm in favor of a new non-recursive algorithm.
           This was done for performance: This way, GFS2 no longer needs to
           lock multiple resource groups while doing truncates and deletes of
           files that cross multiple resource group boundaries, allowing for
           better parallelism. It also solves a problem whereby deleting large
           files would request a large chunk of kernel memory, which resulted
           in a get_page_from_freelist warning.
      
         - Due to a regression found during testing, I added a new patch to
           correct 'GFS2: Prevent BUG from occurring when normal Withdraws
           occur'."

        New feature:
      
         - implement statx
      
        The new implementation of dir.c is kind of a big deal, all new code.
        It has been posted to fs-devel during the previous rc period, we
        didn't get much review or feedback from there, but it has been
        reviewed very heavily here, so much so that we have two entire
        versions of the reimplementation.
      
        Not only does the new implementation fix some xfstests, but it passes
        all the new tests we made here that involve seeking and rewinding and
        giant directories and long file names. The new dir code has three
        patches itself:
      
         - skip forward to the next directory entry if seek is short

      GFS2: Allow glocks to be unlocked after withdraw · ed17545d
      Bob Peterson authored
      This bug fixes a regression introduced by patch 0d1c7ae9.
      
      The intent of the patch was to stop promoting glocks after a
      file system is withdrawn due to a variety of errors, because doing
      so results in a BUG(). (You should be able to unmount after a
      withdraw rather than having the kernel panic.)
      
      Unfortunately, it also stopped demotions, so glocks could not be
      unlocked after withdraw, which means the unmount would hang.
      
      This patch allows function do_xmote to demote locks to an
      unlocked state after a withdraw, but not promote them.

      arm64: Fix the DMA mmap and get_sgtable API with DMA_ATTR_FORCE_CONTIGUOUS · 92f66f84
      Catalin Marinas authored
      While honouring the DMA_ATTR_FORCE_CONTIGUOUS on arm64 (commit
      44176bb3: "arm64: Add support for DMA_ATTR_FORCE_CONTIGUOUS to
      IOMMU"), the existing uses of dma_mmap_attrs() and dma_get_sgtable()
      have been broken by passing a physically contiguous vm_struct with an
      invalid pages pointer through the common iommu API.
      
      Since the coherent allocation with DMA_ATTR_FORCE_CONTIGUOUS uses CMA,
      this patch simply reuses the existing swiotlb logic for mmap and
      get_sgtable.
      
      Note that the current implementation of get_sgtable (both swiotlb and
      iommu) is broken if dma_declare_coherent_memory() is used since such
      memory does not have a corresponding struct page. To be addressed in a
      subsequent patch.

      initramfs: Always do fput() and load modules after rootfs populate · 17a9be31
      Stafford Horne authored
      In OpenRISC we do not have a bootloader passed initrd, but the built in
      initramfs does contain the /init and other binaries, including modules.
      The previous commit 08865514 ("initramfs: finish fput() before
      accessing any binary from initramfs") made a change to only call fput()
      if the bootloader initrd was available, this caused intermittent crashes
      for OpenRISC.
      
      This patch changes the fput() to happen unconditionally if any rootfs is
      loaded. Also, I added some comments to make it a bit more clear why we
      call unpack_to_rootfs() multiple times.

      we arranged for the capacity to be allocated, but failed to also update

      capacity reserved to hold all the allocated sections, but
      vmemmap_populate_hugepages() still encounters -ENOMEM from

      This fix is a stop-gap until we can teach the core memory hotplug

      drm/tegra: Changes for v4.12-rc1
      
      This contains various fixes to the host1x driver as well as a plug for a
      leak of kernel pointers to userspace.
      
      A fairly big addition this time around is the Video Image Composer (VIC)
      support that can be used to accelerate some 2D and image compositing
      operations.
      
      Furthermore the driver now supports FB modifiers, so we no longer rely
      on a custom IOCTL to set those.
      
      Finally this contains a few preparatory patches for Tegra186 support
      which unfortunately didn't quite make it this time, but will hopefully
      be ready for v4.13.

        Guenter and others who have taken the time to get this merged. It
        wasn't an easy path for them at all.
      
        There's also a staging driver that uses this new api, which is why
        it's coming in through this tree.
      
        Along with that, there's the usual huge number of changes for gadget
        drivers, xhci, and other stuff. Johan also finally refactored pretty
        much every driver that was looking at USB endpoints to do it in a
        common way, which will help prevent any "badly-formed" devices from
        causing problems in drivers. That too wasn't a simple task.

      libnvdimm: handle locked label storage areas · 9d62ed96
      Dan Williams authored
      Per the latest version of the "NVDIMM DSM Interface Example" [1], the
      label data retrieval routine can report a "locked" status. In this case
      all regions associated with that DIMM are disabled until the label area
      is unlocked. Provide generic libnvdimm enabling for NVDIMMs with label
      data area locking capabilities.

      libnvdimm: convert NDD_ flags to use bitops, introduce NDD_LOCKED · 8f078b38
      Dan Williams authored
      This is a preparation patch for handling locked nvdimm label regions, a
      new concept as introduced by the latest DSM document on pmem.io [1]. A
      future patch will leverage nvdimm_set_locked() at DIMM probe time to
      flag regions that can not be enabled. There should be no functional
      difference resulting from this change.

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.12 kernel cycle.
      
        Core changes:
      
         - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
           This was a much discussed change. It affects use cases where people
           write drivers that might or might not be using GPIO resources. I
           have decided that this is the lesser evil right now.
      
         - Make gpiod_count() behave consistently across different hardware
           descriptions.
      
         - Fix the syntax around open drain/open source to not infer active
           high/low semantics.
      
        New drivers:
      
         - A new single-register fixed-direction framework driver for hardware
           that have lines controlled by a single register that just work in
           one direction (out or in), including IRQ support.
      
         - Support the Fintek F71889A GPIO SuperIO controller.
      
         - Support the National NI 169445 MMIO GPIO.
      
         - Support for the X-Gene derivative of the DWC GPIO controller
      
         - Support for the Rohm BD9571MWV-M PMIC GPIO controller.
      
         - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
           and replace both the Gemini and the Moxa ART custom drivers with
           this driver.
      
        Driver improvements:
      
         - A whole slew of drivers have their spinlocks chaned to raw
           spinlocks as they provide irqchips, and thus we are progressing on
           realtime compliance.
      
         - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
           resources.
      
         - Support for the embedded PWM controller inside the MVEBU driver.
      
         - Debounce, open source and open drain support for the Aspeed driver.
      
         - Misc smaller fixes like spelling and syntax and whatnot"

      orangefs: count directory pieces correctly · 2f713b5c
      Martin Brandenburg authored
      A large directory full of differently sized file names triggered this.
      Most directories, even very large directories with shorter names, would
      be lucky enough to fit in one server response.

      orangefs: invalidate stored directory on seek · 942835d6
      Martin Brandenburg authored
      If an application seeks to a position before the point which has been
      read, it must want updates which have been made to the directory.  So
      delete the copy stored in the kernel so it will be fetched again.

      orangefs: skip forward to the next directory entry if seek is short · bf15ba7c
      Martin Brandenburg authored
      If userspace seeks to a position in the stream which is not correct, it
      would have returned EIO because the data in the buffer at that offset
      would be incorrect.  This and the userspace daemon returning a corrupt
      directory are indistinguishable.
      
      Now if the data does not look right, skip forward to the next chunk and
      try again.  The motivation is that if the directory changes, an
      application may seek to a position that was valid and no longer is valid.
      
      It is not yet possible for a directory to change.

      of: fix sparse warning in of_pci_range_parser_one · eb310036
      Rob Herring authored
      sparse gives the following warning for 'pci_space':
      
      ../drivers/of/address.c:266:26: warning: incorrect type in assignment (different base types)
      ../drivers/of/address.c:266:26:    expected unsigned int [unsigned] [usertype] pci_space
      ../drivers/of/address.c:266:26:    got restricted __be32 const [usertype] <noident>
      
      It appears that pci_space is only ever accessed on powerpc, so the endian
      swap is often not needed.
