I was happy with the patch Sergei posted a week ago, and said so -
except for the question of whether to say "unlikely(slop)": and
that's a very silly little issue which should never have delayed
fixing a significant regression, I'm sorry I ever raised it.

But I was expecting Alan to gather the fixes together and send them
to you: on 26 Jan he posted two other patches, one perhaps just a
cleanup, but the other he said required for correct behaviour on
AMD devices: I thought all three patches would be in by now.
