Got a pointer? A quick git-grep doesn't show anything in hw/ or

initial value.
Not cpu_index,

Hm, hw/intc/apic_common.c:apic_reset_common() has:
bsp = cpu_is_bsp(s-cpu);
s-apicbase = APIC_DEFAULT_ADDRESS |

I know, that's what this patch is changing, and I am saying that by the
same logic the CPU has no business fiddling
