I doesn't seem that the mooted alternatives will be happening any time
soon,

I would like a version of this patch which has a changelog which fully
describes our reasons for reapplying the reverted revert.  At this
time, *someone* is going to have to carry a private patch.  It's best
that the version which suits the larger number of users be the one
which we carry in mainline.

I'll add a cc:stable to this revert.
