code is undefined for SMP. SMP-People! Could someone extend this to
SMP architectures? Or give me some helpful hints?

You cannot sit in a loop in non-interrupt level code waiting for
jiffies to change with the current SMP/Intel interrupt scheme.
I am working on a generic fix for this issue, and once that is done
you code will word unchanged on SMP.
