Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm fixes from Dan Williams:

 - Fix for the nd_blk (NVDIMM Block Window Aperture) driver.

   A spec clarification requires the driver to mask off reserved bits in
   status register.  This is tagged for -stable back to the v4.2 kernel.

 - Fix for a kernel crash in the nvdimm unit tests when module loading
   is interrupted with SIGTERM.  Tagged for -stable since validation
   efforts external to Intel use the unit tests for qualifying
   backports.

 - Add a new 'size' sysfs attribute for the BTT (NVDIMM Block
   Translation Table) driver to make it symmetric with the other
   namespace personality drivers (PFN and DAX) that provide a size
   attribute for indicating how much namespace capacity is lost to
   metadata.

   The BTT change arrived at the start of the merge window and has
   appeared in a -next release.  It can technically wait for 4.9, but it
   is small, fixes asymmetry in the libnvdimm-sysfs interface, and
   something I would have squeezed into the v4.8 pull request had it
   arrived a few days earlier.
