I used to think that, until some of the first SMP versions of Linux were
just able to accept interrupts to one CPU - which is not strictly
symmetrical. However, I wasn't sure was that must because of kernel
limitations, or hardware limitations...the P90 being the first chip to
have an on-chip I/O APIC, so some board manufacturers could just have only
one I/O APIC to save cost...
