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()" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: device-dax: fix private mapping restriction, permit read-only tools/testing/nvdimm: unit test acpi_nfit_ctl() acpi, nfit: fix bus vs dimm confusion in xlat_status acpi, nfit: validate ars_status output buffer size acpi, nfit, libnvdimm: fix / harden ars_status output length handling acpi, nfit: fix extended status translations for ACPI DSMs
