I just double-checked all the commits that are mentioned in comment #67.
In between (or let's better say since quite some time) they are all in Eoan
master and are also all in Disco master (and with that even in bionic's hwe
kernel, despite comment #66: 'no need to target bionic').
Hence if one uses the default disco and eoan kernel today, it includes the
above list of patches (#67).
With that I change at least the Eoan entry to Fix Released.
** Changed in: linux (Ubuntu Eoan)

FYI: This blocks bug 1781526 - once this one here is resolved we can
go on with SRU considerations for 1781526

Hi, in some environments it was observed that this qemu patch to
enable THP made it more likely to hit guest migration issues, however
the following kernel patch resolves those migration issues:
https://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git/commit/?h=kvm-ppc-next&id=c066fafc595eef5ae3c83ae3a8305956b8c3ef15
KVM: PPC: Book3S HV: Use correct pagesize in kvm_unmap_radix()
Once merged upstream, it would be good to include that change as well
to avoid potential migration problems. Should I open a new bug for
that or is it better to track here?
Note Paelzer: I have not seen related migration issues myself, but it
seems reasonable and confirmed by IBM.
