Nick proposed disabling BookE KVM, which prompted some users to report they are still actively using it: https://lore.kernel.org/all/20221128043623.1745708-1-npig...@gmail.com/ There are also still some KVM PR users.

Ack. cheers

There haven't been many generic KVM changes that touch PPC, but in my experience when such series do come along, the many flavors and layers of PPC incur quite a bit of development and testing cost, and have a high chance of being broken compared to other architectures.
[PATCH] KVM: PPC: Update MAINTAINERS
Michael is merging KVM PPC patches via the powerpc tree and KVM topic branches. He doesn't necessarily have time to be across all of KVM so is reluctant to call himself maintainer, but for the mechanics of how patches flow upstream, it is maintained and does make sense to have some contact people in MAINTAINERS. So add Michael Ellerman as KVM PPC maintainer and myself as reviewer. Split out the subarchs that don't get so much attention.

[RFC PATCH] KVM: PPC: Update MAINTAINERS
Michael is maintaining KVM PPC with the powerpc tree at the moment, just doesn't necessarily have time to be across all of KVM. But I think that's okay, from mechanics of how patches flow upstream he is maintainer. And it probably makes a bit more sense to people who need to look at the MAINTAINERS file if we have some contacts there. So add mpe as KVM PPC maintainer and I am a reviewer. Split out the subarchs that don't get much attention.
