This showed itself on ppc64_defconfig, but not on pasemi_defconfig, so it had gone unnoticed when I initially tested the LE patch set. Fix is to add explicit alignment instead of relying on good luck. :) [ It appears that there is a different issue with PA Semi systems however this fix is definitely correct so applying anyway -- BenH ] Fixes: 5c0484e25ec0 ('powerpc: Endian safe trampoline') Reported-by: Christian Zigotzky Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=67811 Signed-off-by: Olof Johansson Signed-off-by: Benjamin Herrenschmidt --- Reading git-diff-tree failed
