Changes since v2 [1]:
1/ Rebase on the ACPICA enabling for the NFIT data structures. The
ACPICA project owns the definition of ACPI data structures in
include/acpi/. This release incorporates the NFIT and UUID definitions
from ACPICA release R05_15_15 [2]. (Rafael, Bob)
2/ Move the ACPI NFIT driver to drivers/acpi/ (Rafael)
3/ Include documentation of the overall subsystem (Rafael)
4/ Arrange for stable block device names in the case where the platform
configuration has not changed (Toshi and Robert)
5/ Move test infrastructure to the end of the series (Jeff)
6/ Fix up the Kconfig text for CONFIG_ND_BLK to be more descriptive
(Andy)
7/ Report and continue upon detecting unknown NFIT tables rather than
failing (Jeff)
8/ Rename the namespace 'type' attribute to 'nstype' so that lsblk does
not mistake libnd block devices for scsi disks. (Robert and Christoph)
9/ Convert nd_region_{acquire|release}_lane() to user percpu variable
infrastructure (Ross)
Thanks for all of the review!
Note, there are incremental changes to address caching, persistent
flushing, queue flags, and expanded sector size support that are
deferred until this base support is cleared to merge.

The libndctl changes for these updates are available in ndctl.git:
https://github.com/pmem/ndctl
For this set to move forward it needs acks from ACPI and BLOCK layer
developers. I am assuming this will ultimately go upstream via the
block tree. A branch in nvdimm.git will be prepared at the end of the
week to give the pending acks some time to land. Additional feedback
welcome, and hopefully it can be addressed incrementally from this
baseline going forward, i.e. aiming for inclusion in -next and no more
rebases before the 4.2 merge window opens.
