Subject: [GIT PULL] libnvdimm fixes for 4.9-rc7

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm libnvdimm-fixes

...to receive:

* Fix a crash that occurs at driver initialization if the memory region
is already busy (request_mem_region() fails).

* Fix a vma validation check that mistakenly allows a private device-
dax mapping to be established.  Device-dax explicitly forbids private
mappings so it can guarantee a given fault granularity and backing
memory type.

Both of these fixes have soaked in -next and are tagged for -stable.
