Oh, I vaguely remember a version of the Arm Arm been re-issued because 
of the mistakes during the release. This might well have been A.k.

I am not sure why I use A.k because this is a pretty old spec. I should 
have used the last one (i.e D.a).

Anyway, I am indeed referring to `Ensuring the visibility of updates to 
translation tables for a multiprocessor`. I will update the commit message.
