Log:
Revert the previous change. 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.
