  Log:
  SVN rev 189891 on 2009-03-16 17:30:38Z by rwatson
  
  Merge r189545 from head to stable/7:
  
  By default, don't compile in counters of calls to various time
  query functions in the kernel, as these effectively serialize
  parallel calls to the gettimeofday(2) system call, as well as
  other kernel services that use timestamps.
  
  Use the NetBSD version of the fix (kern_tc.c:1.32 by ad@) as
  they have picked up our timecounter code and also ran into the
  same problem.
