      Pull xfs fix from Darrick Wong:
       "Clear out i_mapping error state when we're reinitializing inodes.
      
        This last minute fix prevents writeback error state from persisting
        past the end of the in-core inode lifecycle and causing EIO errors to
        be reported to userspace when no error has occurred.
      
        This fix for the behavioral regression has been soaking in for-next
        for a while, but various fs developers persuaded me to try to get it
        upstream for 4.17 because the patch that broke things was introduced
        in 4.17-rc4"

      Pull x86 platform driver fix from Andy Shevchenko:
       "Fix NULL pointer dereference in asus-wmi on rfkill cleanup.
      
        The effective change is just one new condition - two lines of code.
        But it required moving one static helper function, which is why the
        diff looks a bit bigger"

      João Paulo Rechi Vita authored
      Do not perform the rfkill cleanup routine when
      (asus->driver->wlan_ctrl_by_user && ashs_present()) is true, since
      nothing is registered with the rfkill subsystem in that case. Doing so
      leads to the following kernel NULL pointer dereference:

      fs: clear writeback errors in inode_init_always · 829bc787
      Darrick J. Wong authored
      In inode_init_always(), we clear the inode mapping flags, which clears
      any retained error (AS_EIO, AS_ENOSPC) bits.  Unfortunately, we do not
      also clear wb_err, which means that old mapping errors can leak through
      to new inodes.
      
      This is crucial for the XFS inode allocation path because we recycle old
      in-core inodes and we do not want error state from an old file to leak
      into the new file.  This bug was discovered by running generic/036 and
      generic/047 in a loop and noticing that the EIOs generated by the
      collision of direct and buffered writes in generic/036 would survive the
      remount between 036 and 047, and get reported to the fsyncs (on
      different files!) in generic/047.

      tracing: Make the snapshot trigger work with instances · 2824f503
      Steven Rostedt (VMware) authored
      The snapshot trigger currently only affects the main ring buffer, even when
      it is used by the instances. This can be confusing as the snapshot trigger
      is listed in the instance.

      IB: Revert "remove redundant INFINIBAND kconfig dependencies" · 533d1dae
      Arnd Bergmann authored
      Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends
      on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a
      link error when another driver using it is built-in. The
      INFINIBAND_ADDR_TRANS dependency is insufficient here as this is
      a 'bool' symbol that does not force anything to be a module in turn.

      ARM: Fix i2c-gpio GPIO descriptor tables · f59c303b
      Linus Walleij authored
      I used bad names in my clumsiness when rewriting many board
      files to use GPIO descriptors instead of platform data. A few
      had the platform_device ID set to -1 which would indeed give
      the device name "i2c-gpio".
      
      But several had it set to >=0 which gives the names
      "i2c-gpio.0", "i2c-gpio.1" ...
      
      Fix the offending instances in the ARM tree. Sorry for the
      mess.

      which has been causing eMMC corruption on my HiKey board.

      And quite often this would result in a disk that wouldn't properly
      boot even with older kernels.
      
      It seems the max-frequency property added by the above patch is
      causing the problem, so remove it.

      crypto: inside-secure - do not use memset on MMIO · bf4407f0
      Antoine Tenart authored
      This patch fixes the Inside Secure driver which uses a memtset() call to
      set an MMIO area from the cryptographic engine to 0. This is wrong as
      memset() isn't guaranteed to work on MMIO for many reasons. This led to
      kernel paging request panics in certain cases. Use memset_io() instead.

      kasan: fix memory hotplug during boot · 3f195972
      David Hildenbrand authored
      Using module_init() is wrong.  E.g.  ACPI adds and onlines memory before
      our memory notifier gets registered.
      
      This makes sure that ACPI memory detected during boot up will not result
      in a kernel crash.
      
      Easily reproducible with QEMU, just specify a DIMM when starting up.
