Pull libnvdimm build fix from Dan Williams:
 "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"
