That's the reason why we insisted on __this_cpu*() primitives growing 
these essential debug checks early on - which you resisted. I had to bring 
out NAKs for you to see sense and start fixing the mess already - next 
time around I'll probably have to NAK your changes earlier to prevent such 
mishaps.

( Note that some false positives were possibly fixed by the use of the 
  lib/smp_processor_id.c methods to check for preemptability, so the 
  situation might not be as dire as your first series suggests. )

Thanks,
