non-SMP ? Do people still build those :) ?
Just kidding.

Hmm, why would it be any different ?
I've just build UP kernel with and w/o the patch

size vmlinux

before
    text	   data	    bss	    dec	    hex	filename
3313797	 307060	 310352	3931209	 3bfc49	vmlinux

after
    text	   data	    bss	    dec	    hex	filename
3313797	 307060	 310352	3931209	 3bfc49	vmlinux

I think we're good here.
