Marc -- what would you like to do with this patch? 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
