I think the POE series is really close now, so ideally I'd queue the lot on a branch in arm64 and you could pull the first ~10 patches into kvmarm if you need 'em. Would what work for you, or did you have something else in mind (since this one is also included in your series adding nv support for AT). Cheers, Will
