Subject: CVE request: kernel: exit_notify: kill the wrong capable(CAP_KILL)

A malicious application can execute a setuid binary before exit. This
would mean that we will not reset the ->exit_signal to SIGCHLD unless
the binary drops CAP_KILL.

Chris/Greg, we probably need this in -stable.

Thanks, Eugene
