3.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Neuling <mikey@neuling.org>
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.
