Hmm, i thought there were cases where we checked if it was in kernel mode instead of IPIng, and assume the check is done when returning.
But cannot come up with a concrete example right now. It may have been wrong. Or I forgot it :)
You're right anything with interrupts should be fine because it's just blocked.
