New Revision: 247169
URL: http://svnweb.freebsd.org/changeset/base/247169

Log:
      In preparation for switching linuxulator to the use the native 1:1 threads
      introduce linux_exit() stub instead of calling sys_exit()
      call (which terminates process).
      In the new linuxulator exit() system call terminates the
      calling thread (not a whole process).
