svn commit: r264436 - head/lib/libproc

[Mark Johnston]

Author: markj
Date: Mon Apr 14 00:24:04 2014
New Revision: 264436
URL: http://svnweb.freebsd.org/changeset/base/264436

Log:
  Fix some off-by-one errors. The kve_end and rdl_eaddr fields contain the
  first address after the end of the map entry and should therefore be
  excluded.
