Comment (by Gedare Bloom):

 Two basic questions:
 1. Does the priority field `type` need to be Architecture- or BSP-defined
 or is `uint32_t` always going to be fine.

 2. Does changing (increasing) the priority of a vector from within
 interrupt context possibly cause a pending interrupt to post that was
 previously at a lower priority than the currently masked priority level?
 In that case, it would cause a preemption to occur. I'm guessing this
 behavior could be architecture-specific.
