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.
