2010-11-09Added loads of interrupt processing code.Duncan Smith
Properly handling interrupts that come in a critical section is a difficult problem. This is my first stab at it. Notably, I'm doing all my interrupt processing in softwareland. It turns out to be about 1/3 as fast as using the interrupt hardware directly, though I don't have to run in supervisor mode this way.
