FWIW, I did compile all patches on all KVM architectures, including selftests. But my base obviously didn't include the kvm-arm64 branch :-/ One thing I'll add to my workflow would be to do a local merge (and smoke test) of linux-next into kvm-x86 next before pushing it out. This isn't the only snafu this cycle where such a sanity check would have saved me and others a bit of pain. https://lore.kernel.org/all/20241101153857.GAZyT2EdLXKs7ZmDFx@fat_crate.local
