Fabrice, have you had the chance to check with upstream what is the
most correct fix?

Also, your commit title says it fixes it for powerpc7, but the issue
also appears with older powerpc platforms, and indeed the upstream
commit says it fixes the issue for powerpc7 and older platforms.

Since the issue pops up quite a lot in the autobuilders, it would be
nice if we could finalize this patch and merge it.

Thanks,

Thomas
