[PATCH] memory hotplug: move section_mem_map alloc to sparse.c
This basically keeps up from having to extern __kmalloc_section_memmap(). The vaddr_in_vmalloc_area() helper could go in a vmalloc header, but that header gets hard to work with, because it needs some arch-specific macros. Just stick it in here for now, instead of creating another header.
