wake_up_process() should be never used to wakeup a TASK_STOPPED/TRACED task
wake_up_process() should be never used to wakeup a TASK_STOPPED/TRACED task
CVE-2013-0871
BugLink: http://bugs.launchpad.net/bugs/1129192
wake_up_process() should never wakeup a TASK_STOPPED/TRACED task.
Change it to use TASK_NORMAL and add the WARN_ON().
TASK_ALL has no other users, probably can be killed.
