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.

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-npiggin@gmail.com/ There are also still some KVM PR users. In total I'd guess it's only some small 100s of users, but we don't really know. > 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. Ack. cheers

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.
