This is a bit hard to parse, I don't think you need to explain it in
detail for this particular patch though.

Now we have MPIPL, SYSDUMP, DUMP, FADUMP, and MDST.
Are these all completely different such that this makes sense, or can
we consolidate a bit?
MPIPL -> IPL which preserves some memory ranges from previous execution.
Everything else -> ???
