The first patch fixes a spinlock recursion. I suppose we can ship it back
to stable but I doubt anyone has noticed or cares. The second one adds
break support to the DM path, and allows sysrq to work.

If an attacker can cause a controlled kernel stack overflow,
overwriting the restart block is a very juicy exploit target.
Moving the restart block to struct task_struct prevents this
exploit.
Note that there are other fields in thread_info that are also easy
