description:
Pull up revision 1.65 (via patch, requested by sommerfeld):
  In cpu_fork(), make sure the spawned kthread or process runs at
  IPL_0 instead of whatever IPL the parent was running at.

  This appears to fix the NTP clock stability problems observed on
  some alpha systems; the clock appears stable even when there's
  heavy raidframe (i.e., kthread-intensive) I/O under way.
