Oh, well, I was looking at the older version of the PoP first, and it
was not specified there yet, and when I started looking the the new
version, I only saw the first LAP line and stopped reading properly
afterwards... of course you're right, there is another LAP line in the
table where they say that the address is correclty specified.
Please mentioned the "Enhanced Suppression-on-Protection
Facility 2" (which introduced this new behavior) in the patch
description to make this clear, then your patch is fine.
