My mailer is mutt, and I did not configure "Mail-Follow-To", it should use the
default value. I add "set followup_to=no" to my ~/muttrc file now.

Hope it is got fixed, thanks you for your remind.

I recheck your patch, It seems that I misunderstand it. with your function
register_cpu_node, we can call it in arch_cpu_probe, and then we need not the _emu()
any more. Our _emu() functions work, but it get thing complicated. :)

I will rework patch 4 and patch 5 with your suggestion, thanks.
