Even though Intel insists that the behavior this change restores is wrong, it turns out the "proper" method is worse in practice for existing machines. This is probably due to the fact that using fixed priority with a physical broadcast destination effectively broadcasts interrupts to all CPUs. Fixing that would require a lot more work than just restoring the previous "incorrect" behavior and would probably be riskier as well.
