Subject: [RFC PATCH 5/5] mm, sparse: rename kmalloc_section_memmap, __kfree_section_memmap

From: Michal Hocko <mhocko@...e.com>

Both functions will use altmap rather than kmalloc for sparsemem-vmemmap
so rename them to alloc_section_memmap/free_section_memmap which better
reflect the functionality.
