I applied your patch to 2.1.126-2 -- it applied ok except for one file in
arch/alpha (my systems are all X86).
I then ran 'make xconfig', selected CONFIG_SMP and built -- this went ok.
I then re-ran xconfig and selected a UP build; this resulted in the following
errors:

I next did "make clean ; make bzImage" which worked ok...
