Oleg Nesterov 4449a51a7c vm_is_stack: use for_each_thread() rather then buggy while_each_thread() ...

Aleksei hit the soft lockup during reading /proc/PID/smaps.  David
investigated the problem and suggested the right fix.

while_each_thread() is racy and should die, this patch updates
vm_is_stack().
