CVS commit: src/sys

[Mindaugas Rasiukevicius <rmind%netbsd.org@localhost>]

Module Name:    src
Committed By:   rmind
Date:           Fri Apr 16 03:21:49 UTC 2010

Modified Files:
        src/sys/kern: kern_synch.c
        src/sys/sys: sched.h
        src/sys/uvm: uvm_extern.h uvm_glue.c uvm_meter.c

Log Message:
- Merge sched_pstats() and uvm_meter()/uvm_loadav().  Avoids double loop
  through all LWPs and duplicate locking overhead.

- Move sched_pstats() from soft-interrupt context to process 0 main loop.
  Avoids blocking effect on real-time threads.  Mostly fixes PR/38792.

Note: it might be worth to move the loop above PRI_PGDAEMON.  Also,
sched_pstats() might be cleaned-up slightly.
