Author: Ryan Arnold <ryanarn@etna.rchland.ibm.com>
Date:   Thu May 20 17:05:06 2010 -0500

    Revert "Power7 memset powerpc32 and powerpc64 .S optimizations."
    
    This reverts commit 0a89b6a6fac08b42533075d90d8693ec825bdac1.
    
    A corrected version has been pushed upstream and that will be cherry-picked.
