Yes, I looked at i386 and i686 tuned code as well (which gets the addl), the
core2 tuning has this fixed (I didn't measure on AMD CPUs).  As both 4.1 and
4.2 are way into maintainance mode and the patch which fixed this has not
been identified yet this indeed has only minor chances of getting fixed for
4.1 or 4.2.
