svn commit: r234072 - head/sys/kern

[Jilles Tjoelker]

Author: jilles
Date: Mon Apr  9 21:58:58 2012
New Revision: 234072
URL: http://svn.freebsd.org/changeset/base/234072

Log:
  Remove unused and wrong SA_PROC internal signal property.
  
  The SA_PROC signal property indicated whether each signal number is directed
  at a specific thread or at the process in general. However, that depends on
  how the signal was generated and not on the signal number. SA_PROC was not
  used.
