You mean that smp_processor_id() returns 0 and 4?
I assumed smp_processor_id() < smp_num_cpus: SMP hackers, is this false?
smp_processor_id() is the hardware cpu number, it can be anything. Such numbers are not guarenteed to be contiguous/ordered/etc.
If so, I have to find a new upper bound for smp_processor_id() for SMP, or rewrite much of ip_fw.c...
Why? Just do what the scheduler does, by using asking cpu_number_map[smp_processor_id()], that returns the kind of number you believed smp_processor_id() to be. (grep for "idle_task" in kernel/sched.c)
