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

Pull libnvdimm fixes from Dan Williams:
 "These fixes are all tagged for -stable and have received a build
  success notification from the kbuild robot.

   - NVDIMM namespaces, configured to enforce 1GB alignment, fail to
     initialize on platforms that mis-align the start or end of the
     physical address range.

   - The Linux implementation of the BTT (Block Translation Table) is
     incompatible with the UEFI 2.7 definition of the BTT format. The
     BTT layers a software atomic sector semantic on top of an NVDIMM
     namespace. Linux needs to be compatible with the UEFI definition to
     enable boot support or any pre-OS access of data on a BTT enabled
     namespace.

   - A fix for ACPI SMART notification events, this allows a userspace
     monitor to register for health events rather than poll. This has
     been broken since it was initially merged as the unit test
     inadvertently worked around the problem. The urgency for fixing
     this during the -rc series is driven by how expensive it is to poll
     for this data (System Management Mode entry)"
