mm/page_alloc.c AFAICC it's memmap_init_zone that initialize all pfns of a zone to default values (setting the pages as reserved). Note that for the page structures we don't use the standard memory allocators (kmalloc, vmalloc, etc), we simply calculate the amount of memory that all the structures will hold in, and then allocate a corresponding range of memory. Hope that help.
