svn commit: r269982 - head/sys/ddb

[Warner Losh]

Author: imp
Date: Thu Aug 14 16:01:51 2014
New Revision: 269982
URL: http://svnweb.freebsd.org/changeset/base/269982

Log:
  ins is only set and unused, but only when we're not doing software
  single stepping. Only set it when we're doing that by bending
  style(9) rules a little to avoid even worse #ifdef soup.
