It seems to me that most of the patch conflicts are mechanical
and could be merged mechanically.

However I believe that the documentation change to this comment is important:

I scratched my head for a while to figure out that AT_NOTELF also was
a subtraction as far as AT_VECTOR_SIZE_BASE was concerned.
