X-Git-Tag: v2.6.36-rc1~462

oom: dump_tasks use find_lock_task_mm too fix

When find_lock_task_mm() returns a thread other than p in dump_tasks(),
its name should be displayed instead.  This is the thread that will be
targeted by the oom killer, not its mm-less parent.

This also allows us to safely dereference task->comm without needing
get_task_comm().

While we're here, remove the cast on task_cpu(task) as Andrew suggested.
