svn commit: r303383 - head/sys/kern

[Konstantin Belousov]

Author: kib
Date: Wed Jul 27 11:27:52 2016
New Revision: 303383
URL: https://svnweb.freebsd.org/changeset/base/303383

Log:
  Reduce number of timehands to just two.  This is useful because
  consumers can now be only one tc_windup() call late.
  
  Use C99 initialization.
