Log:
Expand the hack to mask the atpics if 'device atpic' is not in the kernel
during boot up. Now we do a full reset of the 8259As and setup a simple
interrupt handler (we actually borrow the apic one that just does an
immediate iret) to handle any spurious interrupts triggered by either chip.
This should fix some folks that were getting a Trap 30 during bootup of
certain SMP AMD systems. This might get pushed into the 6.0 branch as an
errata. For now a suitable workaround is to add 'device atpic' to your
kernel config.
