Subject[GIT PULL] libnvdimm for 4.7
Date
Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm tags/libnvdimm-for-4.7

...to receive the device driver related nvdimm topic branches for 4.7.

The bulk of this update was stabilized before the merge window and
appeared in -next.  The "device dax" implementation was revised this
week in response to review feedback, and to address failures detected
by the recently expanded ndctl unit test suite.

Not included in this pull request are two dax topic branches (dax error
handling, and dax radix-tree locking).  These topics were deferred to
get a few more days of -next integration testing, and to coordinate a
branch baseline with Ted and the ext4 tree.  Vishal and Ross will send
the error handling and locking topics respectively in the next few
days.

This branch has received a positive build result from the kbuild robot
across 226 configs.

The following changes since commit 1b8d2afde54fade94339f573c4e05644f9ae9866:

  libnvdimm, pfn: fix ARCH=alpha allmodconfig build failure (2016-05-06 10:20:10 -0700)

----------------------------------------------------------------
libnvdimm for 4.7

1/ Device DAX for persistent memory:
   Device DAX is the device-centric analogue of Filesystem DAX
   (CONFIG_FS_DAX).  It allows memory ranges to be allocated and mapped
   without need of an intervening file system.  Device DAX is strict,
   precise and predictable.  Specifically this interface:

   a) Guarantees fault granularity with respect to a given page size
      (pte, pmd, or pud) set at configuration time.

   b) Enforces deterministic behavior by being strict about what fault
      scenarios are supported.

   Persistent memory is the first target, but the mechanism is also
   targeted for exclusive allocations of performance/feature differentiated
   memory ranges.

2/ Support for the HPE DSM (device specific method) command formats.
   This enables management of these first generation devices until a
   unified DSM specification materializes.

3/ Further ACPI 6.1 compliance with support for the common dimm
   identifier format.

4/ Various fixes and cleanups across the subsystem.
