2.6.34-stable review patch.  If anyone has any objections, please let me know.


From: Dan Carpenter <error27@gmail.com>

commit ddf08f4b90a413892bbb9bb2e8a57aed991cd47d upstream.

For kmap_atomic() we call kunmap_atomic() on the returned pointer.
That's different from kmap() and kunmap() and so it's easy to get them
