    Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
    
    Pull libnvdimm fixes from Dan Williams:
     "Several fixes to the DSM (ACPI device specific method) marshaling
      implementation.
    
      I consider these urgent enough to send for 4.9 consideration since
      they fix the kernel's handling of ARS (Address Range Scrub) commands.
      Especially for platforms without machine-check-recovery capabilities,
      successful execution of ARS commands enables the platform to
      potentially break out of an infinite reboot problem if a media error
      is present in the boot path. There is also a one line fix for a
      device-dax read-only mapping regression.
    
      Commits 9a901f5495e2 ("acpi, nfit: fix extended status translations
      for ACPI DSMs") and 325896ffdf90 ("device-dax: fix private mapping
      restriction, permit read-only") are true regression fixes for changes
      introduced this cycle.
    
      Commit efda1b5d87cb ("acpi, nfit, libnvdimm: fix / harden ars_status
      output length handling") fixes the kernel's handling of zero-length
      results, this never would have worked in the past, but we only just
      recently discovered a BIOS implementation that emits this arguably
      spec non-compliant result.
    
      The remaining two commits are additional fall out from thinking
      through the implications of a zero / truncated length result of the
      ARS Status command.
    
      In order to mitigate the risk that these changes introduce yet more
      regressions they are backstopped by a new unit test in commit
      a7de92dac9f0 ("tools/testing/nvdimm: unit test acpi_nfit_ctl()") that
      mocks up inputs to acpi_nfit_ctl()"
