         - Don't fail IOMMU driver initialization when the add_device

           not translated by the IOMMU.  This is pretty common on ARM.

           remove a redundant NULL check.

        Dave Sterba tested and integrated Anand Jain's sysfs improvements.
        Outside of exporting a symbol (ack'd by Greg) these are all internal

        of our sysfs objects to our internal device management structs instead
        of an object off the super block.  It will make device management
        easier overall and it's a better fit for how the sysfs files are used.

      iommu: Ignore -ENODEV errors from add_device call-back · 38667f18
      Joerg Roedel authored
      The -ENODEV error just means that the device is not
      translated by an IOMMU. We shouldn't bail out of iommu
      driver initialization when that happens, as this is a common
      scenario on ARM.
      
      Not returning -ENODEV in the drivers would be a bad idea, as
      the IOMMU core would have no indication whether a device is
      translated or not. This indication is not used at the
      moment, but will probably be in the future.

      cifs: Unset CIFS_MOUNT_POSIX_PATHS flag when following dfs mounts · 1dfd18d0
      Sachin Prabhu authored
      In a dfs setup where the client transitions from a server which supports
      posix paths to a server which doesn't support posix paths, the flag
      CIFS_MOUNT_POSIX_PATHS is not reset. This leads to the wrong directory
      separator being used causing smb commands to fail.
      
      Consider the following case where a dfs share on a samba server points
      to a share on windows smb server.
       # mount -t cifs -o .. //vm140-31/dfsroot/testwin/

      Linus Torvalds authored
      Pull libnvdimm subsystem from Dan Williams:
       "The libnvdimm sub-system introduces, in addition to the
        libnvdimm-core, 4 drivers / enabling modules:
      
        NFIT:
          Instantiates an "nvdimm bus" with the core and registers memory
          devices (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware
          Interface table).
      
          After registering NVDIMMs the NFIT driver then registers "region"
          devices.  A libnvdimm-region defines an access mode and the
          boundaries of persistent memory media.  A region may span multiple
          NVDIMMs that are interleaved by the hardware memory controller.  In
          turn, a libnvdimm-region can be carved into a "namespace" device and
          bound to the PMEM or BLK driver which will attach a Linux block
          device (disk) interface to the memory.
      
        PMEM:
          Initially merged in v4.1 this driver for contiguous spans of
          persistent memory address ranges is re-worked to drive
          PMEM-namespaces emitted by the libnvdimm-core.
      
          In this update the PMEM driver, on x86, gains the ability to assert
          that writes to persistent memory have been flushed all the way
          through the caches and buffers in the platform to persistent media.
          See memcpy_to_pmem() and wmb_pmem().
      
        BLK:
          This new driver enables access to persistent memory media through
          "Block Data Windows" as defined by the NFIT.  The primary difference
          of this driver to PMEM is that only a small window of persistent
          memory is mapped into system address space at any given point in
          time.
      
          Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access
          different portions of the media.  BLK-mode, by definition, does not
          support DAX.
      
        BTT:
          This is a library, optionally consumed by either PMEM or BLK, that
          converts a byte-accessible namespace into a disk with atomic sector
          update semantics (prevents sector tearing on crash or power loss).
      
          The sinister aspect of sector tearing is that most applications do
          not know they have a atomic sector dependency.  At least today's
          disk's rarely ever tear sectors and if they do one almost certainly
          gets a CRC error on access.  NVDIMMs will always tear and always
          silently.  Until an application is audited to be robust in the
          presence of sector-tearing the usage of BTT is recommended.

      sctp: Fix race between OOTB responce and route removal · 29c4afc4
      Alexander Sverdlin authored
      There is NULL pointer dereference possible during statistics update if the route
      used for OOTB responce is removed at unfortunate time. If the route exists when
      we receive OOTB packet and we finally jump into sctp_packet_transmit() to send
      ABORT, but in the meantime route is removed under our feet, we take "no_route"
      path and try to update stats with IP_INC_STATS(sock_net(asoc->base.sk), ...).
      
      But sctp_ootb_pkt_new() used to prepare responce packet doesn't call
      sctp_transport_set_owner() and therefore there is no asoc associated with this
      packet. Probably temporary asoc just for OOTB responces is overkill, so just
      introduce a check like in all other places in sctp_packet_transmit(), where
      "asoc" is dereferenced.
      
      To reproduce this, one needs to
      0. ensure that sctp module is loaded (otherwise ABORT is not generated)
      1. remove default route on the machine
      2. while true; do
           ip route del [interface-specific route]
           ip route add [interface-specific route]
         done
      3. send enough OOTB packets (i.e. HB REQs) from another host to trigger ABORT
         responce

      net-Liquidio: Delete unnecessary checks before the function call "vfree" · 9686f310
      Markus Elfring authored
      The vfree() function performs also input parameter validation.
      Thus the test around the call is not needed.
      
      This issue was detected by using the Coccinelle software.

      amd-xgbe: Add the __GFP_NOWARN flag to Rx buffer allocation · 472cfe71
      Tom Lendacky authored
      When allocating Rx related buffers, alloc_pages is called using an order
      number that is decreased until successful. A system under stress can
      experience failures during this allocation process resulting in a warning
      being issued. This message can be of concern to end users even though the
      failure is not fatal. Since the failure is not fatal and can occur
      multiple times, the driver should include the __GFP_NOWARN flag to
      suppress the warning message from being issued.
