I must be on drugs: of course it's based on Bill Sommerfeld's work.
So sorry!

> Redo the ICU interrupt handling system to better emulate an APIC system.
> This is done by representing the current blockings of interrupts with
> a priority level instead of an interrupt mask. This makes it possible to
> share implementations for spl* functions/macros between both ICU
> and APIC (a must when going MP) systems. In this process, assign
> soft interrupts their own levels to match the way things will be on
> APIC systems where they actually will be real interrupts and not just
> bits in a pending mask as they are now.
