I didn't catch you. For 8 ways dual core system. Lapicid will be 0x10-0x1f, so 0 will be used by ioapic.

The x86 standard is now is tuples of (nodeid, coreid) which means on k8 based systems the cpu apicids will always be densly packed. I haven't seen the reference but I have been assured that is the way things are working. I believe it was Richard Breuner assured me of this In addition in the code cleanups that have been us only use the (nodeid, coreid) as supporting multiple form simultaneously is both confusing, and creates code that is hard to maintain.
