Jake Burkholder	a448b62ac9	Make intr_nesting_level per-process, rather than per-cpu. Setup ... interrupt threads to run with it always >= 1, so that malloc can detect M_WAITOK from "interrupt" context. This is also necessary in order to context switch from sched_ithd() directly.

Jason Evans	0384fff8c5	Major update to the way synchronization is done in the kernel. Highlights ... include: * Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The alpha port is still in transition and currently uses both.) * Per-CPU idle processes. * Interrupts are run in their own separate kernel threads and can be preempted (i386 only).
