Subject: [GIT PULL] libnvdimm build fix for 4.6-final

Hi Linus, please pull from:

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

...to receive a build fix for the usage of HPAGE_SIZE in the last
libnvdimm pull request.  I have taken note that the kbuild robot build
success test does not include results for alpha_allmodconfig.  Thanks
to Guenter for the report.  It's tagged for -stable since the original
fix will land there and cause build problems.

    libnvdimm, pfn: fix ARCH=alpha allmodconfig build failure
    
    I had relied on the kbuild robot for cross build coverage, however it
    only builds alpha_defconfig.  Switch from HPAGE_SIZE to PMD_SIZE, which
    is more widely defined.
