Subject: mm-fix-phys_to_target_node-and-memory_add_physaddr_to_nid-exports-v4
(Stephen) PowerPC header include dependencies make it difficult to include
asm/sparsemem.h in linux/numa.h due to missing definition of pgprot. Move
the declaration of create_section_mapping() to asm/mmzone.h. This has
received a build success notification from the kbuild-robot over 159
configs.
