I seem to recall Michael and I discussed the naming briefly when I added the
maintainer entries for the drivers and that the PAPR acronym is almost as
meaningless to most as the original RPA. While, IBM no longer uses the term
pseries for Power hardware marketing it is the defacto platform identifier in
the Linux kernel tree for what we would call PAPR compliant. All in all I have
no problem with renaming, but maybe we should consider pseries_dlpar or even
simpler ibmdlpar.

Agreed.
