From c324496456208e4a6a377d8a36b8fad76d004c7f Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Mon, 23 Sep 2013 12:04:47 +1000 Subject: [PATCH] powerpc: Remove hard coded FP offsets in alignment handler The alignment handler assumes big endian ordering when selecting the low word of a 64bit floating point value. Use the existing union which works in both little and big endian.
