Log Message:
Rewrite the interrupt handling code:
- Compute the number of CPU pipeline cycles per second using the
  mc146818.
- Use the COMPARE interrupt for the hardclock interrupt.
- Collapse all interrupt priorities into a single priority, and use
  the CPU interrupt inputs to determine the interrupt source (local
  device, PCI device, ISA device, etc.)

This allows us to have interrupt sharing.
