L440gx SMP kernel with only one CPU

[Ronald G Minnich]

Well here is a problem with only one CPU.

>From linuxbios:
        for(i = 0; i < MAX_CPUS; i++) {
                smp_write_processor(mc, i, apic_version,
                        ((processor_id == i)? CPU_BOOTPROCESSOR:0) |
CPU_ENABLED,
                        cpu_features, cpu_feature_flags
                );

        }

Note the enabled.

>From  Linux:
static void __init MP_processor_info (struct mpc_config_processor *m)
{
        int ver;

        if (!(m->mpc_cpuflag & CPU_ENABLED))
                return;

        printk("Processor #%d %s APIC version %d\n",

So this is a problem: linuxbios is telling the kernel that CPUs are
enabled that do not even exist. OK that explains that one problem.

Now why won't SMP with two cpu's work? that's next.
