[PATCH] fix spinlock-debugging smp_processor_id() usage
When a spinlock debugging check hits, we print the CPU number as an
informational thing - but there is no guarantee that preemption is off
at that point - hence we should use raw_smp_processor_id(). Otherwise
DEBUG_PREEMPT will print a warning.
With this fix the warning goes away and only the spinlock-debugging info
is printed.
