memory-hotplug: implement register_page_bootmem_info_section of sparse-vmemmap
For removing memmap region of sparse-vmemmap which is allocated bootmem,
memmap region of sparse-vmemmap needs to be registered by
get_page_bootmem(). So the patch searches pages of virtual mapping and
registers the pages by get_page_bootmem().
Note: register_page_bootmem_memmap() is not implemented for ia64, ppc, s390,
and sparc.
