From e2f5a3c1bec1cf3e7c76c080fd7f21476f05008a Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Tue, 7 Feb 2006 13:55:30 +1100 Subject: [PATCH] powerpc/64: Fix bug in setting floating-point exception mode When loading up the FPU, we were using a 'ld' (load doubleword) instruction to get the FP exception mode from the thread_struct, but it's only an int field. This changes the ld to lwz (load word and zero-extend).
