Move "exit_robust_list" into mm_release() and clear them
We don't want to get rid of the futexes just at exit() time, we want to
drop them when doing an execve() too, since that gets rid of the
previous VM image too.
Doing it at mm_release() time means that we automatically always do it
when we disassociate a VM map from the task.
Please use CVE-2012-0028 for this issue.
