[GIT PULL] libnvdimm updates for 5.1

[Dan Williams]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-for-5.1

...to receive the general libnvdimm update for 5.1, while I track down
a response on the issue highlighted "PMEM as RAM" pull request.

The bulk of this has been in -next since before the merge window
opened, with no known collisions / issues reported. The only detail
worth noting, outside the tag message, is that the
"libnvdimm-start-pad" topic has been truncated to just cleanups and
small fixes. The full topic branch would have doubled down on hacks
around the "section alignment" limitation of the core-mm, instead
effort is now being spent to address that root issue in the memory
hotplug implementation for v5.2. I'll note, since I messed this up in
the past, the topic-branch merges have summary messages as to why the
merge was made.

  Merge branch 'for-5.1/nfit/ars' into libnvdimm-for-next (2019-03-11
12:37:55 -0700)

----------------------------------------------------------------
libnvdimm for v5.1

* Fix nfit-bus command submission regression

* Support retrieval of short-ARS results if the ARS state is "requires
  continuation", and even if the "no_init_ars" module parameter is
  specified.

* Allow busy-polling of the kernel ARS state by allowing root to reset
  the exponential back-off timer.

* Filter potentially stale ARS results by tracking query-ARS relative to
  the previous start-ARS.

* Enhance dax_device alignment checks

* Add support for the Hyper-V family of device-specific-methods (DSMs)

* Add several fixes and workarounds for Hyper-V compatibility.

* Fix support to cache the dirty-shutdown-count at init.
