I added trace code to see how often GET_APIC_ID() is called. For
my 8p AMD box, the  function is called 6 times per cpu during boot.
I have not seen any other calls to the function after early boot
although I'm they occur under some circumstances.

Can you think of a workload where the frequency of calls is
high enough to be significant??
