There is a #define for atomic_dec_and_lock when compiling for UP.  I
suspect that you have been bitten by the broken makefiles, otherwise
everybody would be reporting problems with 2.4.14.  Before you send any
more patches (and before your existing patches are used), please follow
the steps in http://www.tux.org/lkml/#s8-8.

If you still get problems after that, mail the error messages and your
.config instead of sending patches to "fix" bugs which nobody else is
seeing.  You should include the errors you are getting, otherwise we
cannot tell if the patch makes sense or not.
