 On mainline IMHO it should be fixed the hard way, ie. apply the patch
 to fix store motion checks and then work out how to fix all store motion
 bugs.
 This is not possible for the branch, since when sm basically never worked
 in 3.1 development cycle, it would be actually a completely new feature
 coming in hard feature freeze.
