I think it's very paranoid, since legacy vectors never get programmed into
an IOAPIC RTE and should never need EOIing at the local APIC. But you do at
least printk the case that we see the ISR bit set, and you printk the vector
number, so really this v2 patch gives us more information about this bogus
situation than v1 did, so it's a slight improvement overall. So you still
have my Ack.
