execve(2) assumes you already have a process. You get a process by forking another process. The only process we ever create from scratch is init(8), and that takes a s**tload of work (see kern/init_main.c). This is why we have stuff like nfsiod(8) which does nothing but provide the kernel with a process context it can use for other stuff. You could, of course, write a kernel API for creating processes from scratch. They'd still need a parent, but you can use init(8) (pid 1) for that.
