Some BCM6358 devices start with Core #1 instead of Core #0. Apart from that, SMP is restricted to 1 CPU since BCM6358 has a shared TLB, which makes it impossible for the current SMP support to start both CPUs. The problem is that smp_processor_id() returns 0 and then cpu_logical_map() converts that to 1, which accesses an uninitialized position of intc->cpus[], resulting in a kernel panic.
