Subject: Re: Where is acpi_copy_wakeup_routine in lastest kernel?

I see this link told me what have been changed.

https://lists.linux-foundation.org/pipermail/linux-pm/2008-February/016569.html

So my question is mainly focusing on, since there is no definition of
acpi_copy_wakeup_routine, why there we still can see the declaration
of this routine?

Thanks.

Regards
Jason
