svn commit: r249514 - head/sys/kern

[George V. Neville-Neil]

Author: gnn

New Revision: 249514
URL: http://svnweb.freebsd.org/changeset/base/249514

Log:
  Point args[0] not at the thread that is ending but at the one that
  is starting.  This is in line with practice in OpenSolaris.
  
  Note that this change is only in ULE and not in the 4BSD scheduler.
  Once this change settles in (MFC timeout has expired) we'll try it out
  on 4BSD as well.
