These patches are from upstream and should apply cleanly to 1.6.4, and only slightly less cleanly to other 1.6.x versions. Patches 0001 through 0010 address OPENAFS-SA-2013-0003. Patch 0012 addresses OPENAFS-SA-2013-0004. You probably don't need patch 0011, which is about bumping the version number.
