        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.
