      Pull SCSI fixes from James Bottomley:
       "This is two driver fixes (megaraid_sas and hisi_sas).
      
        The megaraid one is a revert of a previous revert of a cpu hotplug fix
        which exposed a bug in the block layer which has been fixed in this
        merge window.
      
        The hisi_sas performance enhancement comes from switching to interrupt
        managed completion queues, which depended on the addition of
        devm_platform_get_irqs_affinity() which is now upstream via the irq
        tree in the last merge window"

           syscalls which take 64-bit arguments to the compat handlers due to
           former having a general compat handler. (Brian Gerst)

           where a pmd page is freed. (Dan Williams)
      
         - Make IN/OUT insns with an u8 immediate port operand handling for
           SEV-ES guests more precise by using only the single port byte and
           not the whole s32 value of the insn decoder. (Peter Gonda)
      
         - Correct a straddling end range check before returning the proper
           MTRR type, when the end address is the same as top of memory.
           (Ying-Tsun Huang)
      
         - Change PQR_ASSOC MSR update scheme when moving a task to a resctrl
           resource group to avoid significant performance overhead with some
           resctrl workloads. (Fenghua Yu)

      its internals like ->files and ->mm to be poked by the SQPOLL task, it
      have never been nice and recently got racy. That can happen when the
      owner undergoes destruction and SQPOLL tasks tries to submit new
      requests in parallel, and so calls io_sq_thread_acquire*().
      
      That patch halts SQPOLL submissions when sqo_task dies by introducing
      sqo_dead flag. Once set, the SQPOLL task must not do any submission,
      which is synchronised by uring_lock as well as the new flag.
      
      The tricky part is to make sure that disabling always happens, that
      means either the ring is discovered by creator's do_exit() -> cancel,
      or if the final close() happens before it's done by the creator. The
      last is guaranteed by the fact that for SQPOLL the creator task and only
      it holds exactly one file note, so either it pins up to do_exit() or
      removed by the creator on the final put in flush. (see comments in
      uring_flush() around file->f_count == 2).
      
      One more place that can trigger io_sq_thread_acquire_*() is
      __io_req_task_submit(). Shoot off requests on sqo_dead there, even
      though actually we don't need to. That's because cancellation of
      sqo_task should wait for the request before going any further.
      
      note 1: io_disable_sqo_submit() does io_ring_set_wakeup_flag() so the
      caller would enter the ring to get an error, but it still doesn't
      guarantee that the flag won't be cleared.
      
      note 2: if final __userspace__ close happens not from the creator
      task, the file note will pin the ring until the task dies.

      bcache: set bcache device into read-only mode for BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET · 5342fd42
      Coly Li authored
      If BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET is set in incompat feature
      set, it means the cache device is created with obsoleted layout with
      obso_bucket_site_hi. Now bcache does not support this feature bit, a new
      BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE incompat feature bit is added
      for a better layout to support large bucket size.
      
      For the legacy compatibility purpose, if a cache device created with
      obsoleted BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET feature bit, all bcache
      devices attached to this cache set should be set to read-only. Then the
      dirty data can be written back to backing device before re-create the
      cache device with BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE feature bit
      by the latest bcache-tools.
      
      This patch checks BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET feature bit
      when running a cache set and attach a bcache device to the cache set. If
      this bit is set,
      - When run a cache set, print an error kernel message to indicate all
        following attached bcache device will be read-only.
      - When attach a bcache device, print an error kernel message to indicate
        the attached bcache device will be read-only, and ask users to update
        to latest bcache-tools.
      
      Such change is only for cache device whose bucket size >= 32MB, this is
      for the zoned SSD and almost nobody uses such large bucket size at this
      moment. If you don't explicit set a large bucket size for a zoned SSD,
      such change is totally transparent to your bcache device.

      bcache: introduce BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE for large bucket · b16671e8
      Coly Li authored
      When large bucket feature was added, BCH_FEATURE_INCOMPAT_LARGE_BUCKET
      was introduced into the incompat feature set. It used bucket_size_hi
      (which was added at the tail of struct cache_sb_disk) to extend current
      16bit bucket size to 32bit with existing bucket_size in struct
      cache_sb_disk.
      
      This is not a good idea, there are two obvious problems,
      - Bucket size is always value power of 2, if store log2(bucket size) in
        existing bucket_size of struct cache_sb_disk, it is unnecessary to add
        bucket_size_hi.
      - Macro csum_set() assumes d[SB_JOURNAL_BUCKETS] is the last member in
        struct cache_sb_disk, bucket_size_hi was added after d[] which makes
        csum_set calculate an unexpected super block checksum.
      
      To fix the above problems, this patch introduces a new incompat feature
      bit BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE, when this bit is set, it
      means bucket_size in struct cache_sb_disk stores the order of power-of-2
      bucket size value. When user specifies a bucket size larger than 32768
      sectors, BCH_FEATURE_INCOMPAT_LOG_LARGE_BUCKET_SIZE will be set to
      incompat feature set, and bucket_size stores log2(bucket size) more
      than store the real bucket size value.
      
      The obsoleted BCH_FEATURE_INCOMPAT_LARGE_BUCKET won't be used anymore,
      it is renamed to BCH_FEATURE_INCOMPAT_OBSO_LARGE_BUCKET and still only
      recognized by kernel driver for legacy compatible purpose. The previous
      bucket_size_hi is renmaed to obso_bucket_size_hi in struct cache_sb_disk
      and not used in bcache-tools anymore.
      
      For cache device created with BCH_FEATURE_INCOMPAT_LARGE_BUCKET feature,
      bcache-tools and kernel driver still recognize the feature string and
      display it as "obso_large_bucket".
      
      With this change, the unnecessary extra space extend of bcache on-disk
      super block can be avoided, and csum_set() may generate expected check
      sum as well.

      Now if the bcache device created by bcache-tools has features that

      Pull iommu fixes from Will Deacon:
       "This is mainly all Intel VT-D stuff, but there are some fixes for AMD
        and ARM as well.
      
        We've also got the revert I promised during the merge window, which
        removes a temporary hack to accomodate i915 while we transitioned the
        Intel IOMMU driver over to the common DMA-IOMMU API.
      
        Finally, there are still a couple of other VT-D fixes floating around,
        so I expect to send you another batch of fixes next week.
      
        Summary:
      
         - Fix VT-D TLB invalidation for subdevices
      
         - Fix VT-D use-after-free on subdevice detach
      
         - Fix VT-D locking so that IRQs are disabled during SVA bind/unbind
      
         - Fix VT-D address alignment when flushing IOTLB
      
         - Fix memory leak in VT-D IRQ remapping failure path
      
         - Revert temporary i915 sglist hack now that it is no longer required
      
         - Fix sporadic boot failure with Arm SMMU on Qualcomm SM8150
      
         - Fix NULL dereference in AMD IRQ remapping code with remapping disabled
      
         - Fix accidental enabling of irqs on AMD resume-from-suspend path
      
         - Fix some typos in comments"

      Pull ARM SoC fixes from Arnd Bergmann:
       "These are a small number of bug fixes that all came in before or
        during the merge window, most for the omap platform:
      
         - One boot regression fix for Nokia N9 (OMAP3).
      
         - Two small defconfig changes for omap2, to reflect changes in
           drivers
      
         - Warning fixes for DT issues on omap2, picoxcell and bitmap SoCs.
      
           The picoxcell platform will be removed in v5.12, but fixing it
           first makes it easier to backport to the fix to stable kernels and
           get a clean build with new dtc versions"

      HSDK has hardware floating point and the common use case is with
      glibc+hf so enable that as default.
