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

Pull libnvdimm fixes from Dan Williams:

 - Two bug fixes for misuse of PAGE_MASK in scatterlist and dma-debug.
   These are tagged for -stable.  The scatterlist impact is potentially
  corrupted dma addresses on HIGHMEM enabled platforms.

 - A minor locking fix for the NFIT hot-add implementation that is new
   in 4.4-rc.  This would only trigger in the case a hot-add raced
   driver removal.
