Subject: lapic_suspend/lapic_resume wrong?

Hi,

while trying to find the reason for a hanging kernel during resume
handling I found a strange inconsistency in arch/x86/kernel/apic/apic.c
regarding usage of config options.

Attached patch addresses this, no test done as I'm not sure whether
this is a correct approach. Can you have a look at it, please?

Juergen
