Ingo, could you please review and let us know whether this matches what you had in mind? This patchset is on top of kvm/next since it touches some of the code modified in that tree (and patch 3 reverts a commit in that tree). Could x86 some maintainers pls ACK merging this patchset through the kvm tree? Michael S.
