The most notable item is the tidying up of the way we deal with the guest physical space, which had a couple of warts. The other patches address i-cache isolation between vcpus (they are supposed to be vcpu-private, but can not being so...), and a fix for a link-time issue that can occur with LTO. Note that this time around, this pull request is on top of kvm/next, right after the patches you applied last week. Please pull, M.
