When creating a map beyond EOF, extra anonymous pages are added up to the target page boundary. Currently, this operation is performed only when qemu_real_host_page_size < TARGET_PAGE_SIZE, but it should be performed if the configured page size (qemu -p) is larger than qemu_real_host_page_size too.
