      Pull MD updates from Shaohua Li:
      
       - a raid5 writeback cache feature.
      
         The goal is to aggregate writes to make full stripe write and reduce
         read-modify-write. It's helpful for workload which does sequential
         write and follows fsync for example. This feature is experimental and
         off by default right now.
      
       - FAILFAST support.
      
         This fails IOs to broken raid disks quickly, so can improve latency.
         It's mainly for DASD storage, but some patches help normal raid array
         too.
      
       - support bad block for raid array with external metadata
      
       - AVX2 instruction support for raid6 parity calculation
      
       - normalize MD info output
      
       - add missing blktrace
      
       - other bug fixes

       "This update includes the usual round of major driver updates (ncr5380,
        lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).
      
        There's also an assortment of minor fixes, mostly in error legs or
        other not very user visible stuff. The major change is the
        pci_alloc_irq_vectors replacement for the old pci_msix_.. calls; this
        effectively makes IRQ mapping generic for the drivers and allows
        blk_mq to use the information"

      Revert "nvme: add support for the Write Zeroes command" · cdb98c26
      Linus Torvalds authored
      This reverts commit 6d31e3ba.
      
      This causes bootup problems for me both on my laptop and my desktop.
      What they have in common is that they have NVMe disks with dm-crypt, but
      it's not the same controller, so it's not controller-specific.
      
      Jens does not see it on his machine (also NVMe), so it's presumably
      something that triggers just on bootup.  Possibly related to dm-crypt
      and the fact that I mark my luks volume with "allow-discards" in
      /etc/crypttab.
      
      It's 100% repeatable for me, which made it fairly straightforward to
      bisect the problem to this commit. Small mercies.
      
      So we don't know what the reason is yet, but the revert is needed to get
      things going again.

       "The main bulk of the s390 patches for the 4.10 merge window:
      
         - Add support for the contiguous memory allocator.
      
         - The recovery for I/O errors in the dasd device driver is improved,
           the driver will now remove channel paths that are not working
           properly.
      
         - Additional fields are added to /proc/sysinfo, the extended
           partition name and the partition UUID.
      
         - New naming for PCI devices with system defined UIDs.
      
         - The last few remaining alloc_bootmem calls are converted to
           memblock.
      
         - The thread_info structure is stripped down and moved to the
           task_struct. The only field left in thread_info is the flags field.
      
         - Rework of the arch topology code to fix a fake numa issue.
      
         - Refactoring of the atomic primitives and add a new preempt_count
           implementation.
      
         - Clocksource steering for the STP sync check offsets.

      ata: avoid probing NCQ Prio Support if not explicitly requested · 9f56eca3
      Adam Manzanares authored
      Previously, when the ata device was being initialized we were
      probing for NCQ prio support by checking the identify information
      and also checking the log page that holds information about ncq prio
      support.
      
      This caused an error on an Intel HBA so the code is now updated to
      only probe for NCQ prio support when the sysfs variable controlling
      NCQ prio support is enabled.
      
      tj: Update formatting, switch to spin_[un]lock_irq() and update
          locking a bit, use REVALIDATE instead of RESET, and return -EIO
          instead of -EINVAL on config failure.

        implement it as a virtual PCIe root bridge, similar to Intels other
        'innovation' VMD that we work around that way.
      
        But Intel management has apparently decided that they don't want to
        spend more cycles on this now that Lenovo has an optional BIOS that
        doesn't force this broken mode anymore, and no one outside of Intel
        has enough information to implement something like this.

      dm flakey: introduce "error_writes" feature · ef548c55
      Mike Snitzer authored
      Recent dm-flakey fixes, to have reads error out during the "down"
      interval, made it so that the previous read behaviour is no longer
      available.
      
      It is useful to have reads complete like normal but have writes error
      out, so make it possible again with a new "error_writes" feature.

       "Here's the new driver core patches for 4.10-rc1.
      
        Big thing here is the nice addition of "functional dependencies" to
        the driver core. The idea has been talked about for a very long time,
        great job to Rafael for stepping up and implementing it. It's been
        tested for longer than the 4.9-rc1 date, we held off on merging it
        earlier in order to feel more comfortable about it.
      
        Other than that, it's just a handful of small other patches, some good
        cleanups to the mess that is the firmware class code, and we have a
        test driver for the deferred probe logic.

        Not as big as 4.9 was, but still just over a thousand changes. We
        almost broke even of lines added vs. removed, as the slicoss driver
        was removed (got a "clean" driver for the same hardware through the
        netdev tree), and some iio drivers were also dropped, but I think we
        ended up adding a few thousand lines to the source tree in the end.
        Other than that it's a lot of minor fixes all over the place, nothing
        major stands out at all.

      Pull block layer updates from Jens Axboe:
       "This is the main block pull request this series. Contrary to previous
        release, I've kept the core and driver changes in the same branch. We
        always ended up having dependencies between the two for obvious
        reasons, so makes more sense to keep them together. That said, I'll
        probably try and keep more topical branches going forward, especially
        for cycles that end up being as busy as this one.
      
        The major parts of this pull request is:
      
         - Improved support for O_DIRECT on block devices, with a small
           private implementation instead of using the pig that is
           fs/direct-io.c. From Christoph.
      
         - Request completion tracking in a scalable fashion. This is utilized
           by two components in this pull, the new hybrid polling and the
           writeback queue throttling code.
      
         - Improved support for polling with O_DIRECT, adding a hybrid mode
           that combines pure polling with an initial sleep. From me.
      
         - Support for automatic throttling of writeback queues on the block
           side. This uses feedback from the device completion latencies to
           scale the queue on the block side up or down. From me.
      
         - Support from SMR drives in the block layer and for SD. From Hannes
           and Shaun.
      
         - Multi-connection support for nbd. From Josef.
      
         - Cleanup of request and bio flags, so we have a clear split between
           which are bio (or rq) private, and which ones are shared. From
           Christoph.
      
         - A set of patches from Bart, that improve how we handle queue
           stopping and starting in blk-mq.
      
         - Support for WRITE_ZEROES from Chaitanya.
      
         - Lightnvm updates from Javier/Matias.
      
         - Supoort for FC for the nvme-over-fabrics code. From James Smart.
      
         - A bunch of fixes from a whole slew of people, too many to name
           here"

      Pull VFIO updates from Alex Williamson:
      
       - VFIO updates for v4.10 primarily include a new Mediated Device
         interface, which essentially allows software defined devices to be
         exposed to users through VFIO. The host vendor driver providing this
         virtual device polices, or mediates user access to the device.
      
         These devices often incorporate portions of real devices, for
         instance the primary initial users of this interface expose vGPUs
         which allow the user to map mediated devices, or mdevs, to a portion
         of a physical GPU. QEMU composes these mdevs into PCI representations
         using the existing VFIO user API. This enables both Intel KVM-GT
         support, which is also expected to arrive into Linux mainline during
         the v4.10 merge window, as well as NVIDIA vGPU, and also Channel I/O
         devices (aka CCW devices) for s390 virtualization support. (Kirti
