i understood it as Interrupt Privilege Levels. The notion of having some
sort of scalar 'limit' - all interrupts with a higher priority than that
will execute, all interrupts with lower priority will block. This is a
fundamentally dodgy concept because in reality interrupt sources are
independent entities so the natural description for of them is a bitmask
(or an array, or whatever), not a level.
