[GIT PULL] libnvdimm fixes for 4.17-rc2

[Williams, Dan J]

Hi Linus, please pull from

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm libnvdimm-fixes

...to receive, a regression fix, new unit test infrastructure and a
build fix.

+ACo- The regression fix addresses support for the new NVDIMM label storage
area access commands (+AF8-LSI, +AF8-LSR, and +AF8-LSW). The Intel specific version
of these commands communicated the +ACI-Device Locked+ACI- status on the label-
storage-information command. However, these new commands (standardized
in ACPI 6.2) communicate the +ACI-Device Locked+ACI- status on the label-
storage-read command, and the driver was missing the indication.
Reading from locked persistent memory is similar to reading unmapped
PCI memory space, returns all 1's.

+ACo- Unit test infrastructure is added to regression test the +ACI-Device
Locked+ACI- detection failure.

+ACo- A build fix is included to allow the +ACI-of+AF8-pmem+ACI- driver to be built as
a module and translate an Open Firmware described device to its local
numa node.
