From c69e63b0f135fa51d6e1c38b5ac8a1def15ea3fa Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Wed, 2 Oct 2013 17:15:15 +1000 Subject: powerpc/tm: Turn interrupts hard off in tm_reclaim() 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.
