Agreed. I think this is basically an android-only issue (with
_possibly_ some impact on crazy "pin-and-fork" loads), and doesn't
necessarily merit a backport at all.
If Android people insist on using very old kernels, knowing that they
do things that are questionable with those old kernels, at some point
it's just _their_ problem.
