CVS commit: src/sys

[Andrew Doran <ad%netbsd.org@localhost>]

Module Name:    src
Committed By:   ad
Date:           Sat Apr 12 17:02:09 UTC 2008

Modified Files:
        src/sys/kern: kern_cpu.c kern_sleepq.c kern_synch.c sched_4bsd.c
            sched_m2.c
        src/sys/sys: lwp.h sched.h

Log Message:
Take the run queue management code from the M2 scheduler, and make it
mandatory. Remove the 4BSD run queue code. Effects:

- Pluggable scheduler is only responsible for co-ordinating timeshared jobs.
- All systems run with per-CPU run queues.
- 4BSD scheduler gets processor sets / affinity.
- 4BSD scheduler gets a significant peformance boost on some workloads.

Discussed on tech-kern@.
