Sorry for the late response. I was in the reviewing of the previous
patch series and missed this one.
IMO, PeterZ' patch already follows the suggestion at
https://lore.kernel.org/all/87pm4bp54z.ffs@tglx/
And https://lore.kernel.org/all/87jzukqjvf.ffs@tglx/ is not needed
because there are no duplicate APIC IDs from LAPIC and x2APIC anymore
with the above patch.
So I think we can go with PeterZ' patch.
thanks,
rui
