text_poke() itself only applies/unapplies the LOCK prefix - a single

insignificant (a few cycles) and most systems are SMP anyway.
Alas, on older CPUs the cost of LOCK can be massive.  The question is 
how much we really care - the embedded people (who would definitely be 
affected) will simply build UP kernels, and this only affects booting 
SMP kernels on UP.
