linux-next: build failure after merge of the nvdimm tree

[Stephen Rothwell]

Hi Dan,

After merging the nvdimm tree, today's linux-next build (powerpc
allyesconfig) failed like this:

In file included from /home/sfr/next/next/fs/dax.c:28:0:
include/linux/pmem.h: In function 'memcpy_from_pmem':
include/linux/pmem.h:79:9: error: implicit declaration of function 'arch_memcpy_from_pmem' [-Werror=implicit-function-declaration]
  return arch_memcpy_from_pmem(dst, src, size);
         ^

Caused by commit

  a2b056ea291d ("x86, pmem: use memcpy_mcsafe() for memcpy_from_pmem()")

I used the nvdimm tree from next-20160324 for today.
