Pull nvdimm mcsafe_memcpy use from Dan Williams:
"Now that mcsafe_memcpy() has landed, and the return value was been
clarified in commit
cbf8b5a2b649 ("x86/mm, x86/mce: Fix return
type/value for memcpy_mcsafe()"), let's hook up its primary usage in
the pmem driver.
The compilation problems from the initial posting have been fixed,
this has appeared in a -next release with no reported issues, and it
picked up an ack from Ingo. There is no pressing need to merge this
in 4.6- rc2. However, if we wait until 4.7 the new memcpy_mcsafe()
capability will ship without a user in 4.6-final"
