Hello Maintainers:

Under my x86_64 dual core laptop, I build kernel next-20130927 with
'allmodconfig', and install it, the machine can not start. Related
information is:

  after call debug_hotplug_cpu(), output "cpu 0 is offline" .... and then "Failed to execute /init".

After remove "_debug_hotplug_cpu(0, 0);", can pass the issue (but will
fail in another place). I guess, the reason is my laptop cpu is not
'hotplug', but have to call debug_hotplug_cpu() with allmodconfig.


I will continue analyzing, welcome any additional suggestions or
completions.

Thanks.
