       "From a feature point of view, most of the code here comes from Miao
        Xie and others at Fujitsu to implement scrubbing and replacing devices
        on raid56.  This has been in development for a while, and it's a big
        improvement.
      
        Filipe and Josef have a great assortment of fixes, many of which solve
        problems corruptions either after a crash or in error conditions.  I
        still have a round two from Filipe for next week that solves
        corruptions with discard and block group removal"

      HID: rmi: The address of query8 must be calculated based on which query registers are present · cabd9b5f
      Andrew Duggan authored
      If a touchpad does not report relative data then query 6 will not be present and the address
      of query 8 will be one less. This patches calculates the location of query 8 instead of
      hardcoding the offset.

      HID: rmi: Check for additional ACM registers appended to F11 data report · 8414947a
      Andrew Duggan authored
      If a touchpad reports the F11 data40 register then this indicates that the touchpad reports
      additional ACM (Accidental Contact Mitigation) data after the F11 data in the HID attention
      report. These additional bytes shift the position of the F30 button data causing the driver
      to incorrectly report button state when this functionality is present. This patch accounts
      for the additional data in the report.

      HID: i2c-hid: prevent buffer overflow in early IRQ · d1c7e29e
      Gwendal Grignou authored
      Before ->start() is called, bufsize size is set to HID_MIN_BUFFER_SIZE,
      64 bytes. While processing the IRQ, we were asking to receive up to
      wMaxInputLength bytes, which can be bigger than 64 bytes.
      
      Later, when ->start is run, a proper bufsize will be calculated.
      
      Given wMaxInputLength is said to be unreliable in other part of the
      code, set to receive only what we can even if it results in truncated
      reports.

      Pull workqueue update from Tejun Heo:
       "Work items which may be involved in memory reclaim path may be
        executed by the rescuer under memory pressure.  When a rescuer gets
        activated, it processes whatever are on the pending list and then goes
        back to sleep until the manager kicks it again which involves 100ms
        delay.
      
        This is problematic for self-requeueing work items or the ones running
        on ordered workqueues as there always is only one work item on the
        pending list when the rescuer kicks in.  The execution of that work
        item produces more to execute but the rescuer won't see them until
        after the said 100ms has passed, so such workqueues would only execute
        one work item every 100ms under prolonged memory pressure, which BTW
        may be being prolonged due to the slow execution.
      
        Neil wrote up a patch which fixes this issue by keeping the rescuer
        working as long as the target workqueue is busy but doesn't have
        enough workers"

      HID: logitech-hidpp: disable io in probe error path · f486d9db

      Balance a hid_device_io_start() call with hid_device_io_stop() in the
      error path. This avoids processing of HID reports when the probe fails
      which possibly leads to invalid memory access in hid_device_probe() as
      report_enum->report_id_hash might already be freed via
      hid_close_report().
      
      hid_set_drvdata() is called before wtp_allocate, be consistent and clear
      drvdata too on the error path of wtp_allocate.

      pstore-ram: Allow optional mapping with pgprot_noncached · 027bc8b0
      Tony Lindgren authored
      On some ARMs the memory can be mapped pgprot_noncached() and still
      be working for atomic operations. As pointed out by Colin Cross
      <ccross@android.com>, in some cases you do want to use
      pgprot_noncached() if the SoC supports it to see a debug printk
      just before a write hanging the system.
      
      On ARMs, the atomic operations on strongly ordered memory are
      implementation defined. So let's provide an optional kernel parameter
      for configuring pgprot_noncached(), and use pgprot_writecombine() by
      default.

      pstore-ram: Fix hangs by using write-combine mappings · 7ae9cb81
      Rob Herring authored
      Currently trying to use pstore on at least ARMs can hang as we're
      mapping the peristent RAM with pgprot_noncached().
      
      On ARMs, pgprot_noncached() will actually make the memory strongly
      ordered, and as the atomic operations pstore uses are implementation
      defined for strongly ordered memory, they may not work. So basically
      atomic operations have undefined behavior on ARM for device or strongly
      ordered memory types.
      
      Let's fix the issue by using write-combine variants for mappings. This
      corresponds to normal, non-cacheable memory on ARM. For many other
      architectures, this change does not change the mapping type as by
      default we have:
      
      #define pgprot_writecombine pgprot_noncached
      
      The reason why pgprot_noncached() was originaly used for pstore
      is because Colin Cross <ccross@android.com> had observed lost
      debug prints right before a device hanging write operation on some
      systems. For the platforms supporting pgprot_noncached(), we can
      add a an optional configuration option to support that. But let's
      get pstore working first before adding new features.
