Merge tag 'libnvdimm-for-5.1' of git://git.kernel.org/pub/scm/linux/k…

…ernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
 "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 summary below, 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.

   - 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"
