I just had a quick check, and while there is a small conflict with kvmarm/next, it is extremely minor (small clash in the vcpu_sysreg, for which the resolving order doesn't matter), and not worth dragging additional patches in the shared branch. However, if KVM's own S1PIE series [1] ends up being merged (which I'd really like), I will definitely have to pull the prefix in, as this is a bit more involved conflict wise. Thanks, M.
