Without "initial apicid" the awk script will not match and a
"disable_cpu_apicid=N" arguement won't be passed to the crash
This is actually good as the assumption that "CPU 0 == bsp" wouldn't
hold in a virutal environment.
Howerver, this does mean that a kvm instance might still have difficultly
specifying nr_cpus > 1 for crash kernel.
Longer term we should look into having something more explicit exported
to user space saying which CPU is ths bsp. I know Vivek has mentioned
this previously. If this information was available in both real hardware
and virtual system, the above test could be modified.
OK, this makes sense to me. Thanks Jerry.
