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

------------------

From: Michael Neuling <[email protected]>

commit c69e63b0f135fa51d6e1c38b5ac8a1def15ea3fa upstream.

We can't take IRQs in tm_reclaim as we might have a bogus r13 and r1.

This turns IRQs hard off in this function.
