Date: Fri, 11 Oct 2013 12:39:07 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Michael Neuling <mikey@...ling.org>, Benjamin Herrenschmidt <benh@...nel.crashing.org> Subject: [ 066/135] powerpc/tm: Turn interrupts hard off in tm_reclaim() 3.11-stable review patch. If anyone has any objections, please let me know. ------------------ From: Michael Neuling <mikey@...ling.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.
