jhb c92c2d6926 Enable interrupt preemption on Alpha. Previously, flipping this switch on ... caused hangs on SMP systems under load. My theory was that an interrupted thread was migrating and returning to PAL on a different CPU and that that caused the hangs. To prevent this, I used the recently added sched_pin() API to pin the interrupted thread to the CPU that received the interrupt across ithread_schedule() to prevent migration. This seems to have fixed the hangs based on tests by several folks on the alpha@ list. Tested by: wilko, tisco, several others on alpha@		2004-03-23 22:28:16 +00:00
