CVS commit: src/sys/kern

Module Name:    src
Committed By:   ad
Date:           Sat Apr  4 20:17:58 UTC 2020

Modified Files:
        src/sys/kern: kern_runq.c

Log Message:
- sched_idle(): if a migration took place, rather than going idle briefly
  to avoid stealing back the LWP, remember the target CPU and avoid it.

- sched_preempted(): only choose a totally idle CPU; in the interests of
  overall throughput it's better to make use of SMT / slow CPUs.
