And again, by "should work" I mean that it would disable this entirely
on things like arm32 until the arm people decide they care. But at
least it won't use an unsafe non-working 64-bit cmpxchg.

And no, for 6.7, only fix reported bugs. No big reorgs at all,
particularly for something that likely has never been hit by any user
and sounds like this all just came out of discussion.
