Subject: [PATCH v3 0/2] Support ACPI 6.1 update in NFIT Control Region Structure

ACPI 6.1, Table 5-133, updates NVDIMM Control Region Structure as
follows.
 - Valid Fields, Manufacturing Location, and Manufacturing Date
   are added from reserved range.  No change in the structure size.
 - IDs (SPD values) are stored as arrays of bytes (i.e. big-endian
   format).  The spec clarifies that they need to be represented
   as arrays of bytes as well.

Patch 1 changes the NFIT driver to comply with ACPI 6.1.
Patch 2 adds a new sysfs file "id" to show NVDIMM ID defined in ACPI 6.1.

The patch-set applies on linux-pm.git acpica.

 - Need to coordinate with ACPICA update (Bob Moore, Dan Williams)
 - Integrate with ACPICA changes in struct acpi_nfit_control_region.
   (commit 138a95547ab0)

v2:
 - Remove 'mfg_location' and 'mfg_date'. (Dan Williams)
 - Rename 'unique_id' to 'id' and make this change as a separate patch.
