In the thread Paul Mackerras also mentions others fixes. Pasting here for reference.

I went through all the KVM PPC patches since 4.15 and checked whether each one was in Ubuntu as of the Ubuntu-4.15.0-12.13 tag. The ones that aren't in there that we want are:

* Allow HPT guests on P9 DD2.2 without requiring indep_threads_mode=N.
