Do you mean, drop these nmi window bits completely from 2.6.29, keeping
just injection? We can do that without breaking released userspace by
dropping KVM_CAP_NMI and adding KVM_CAP_NMI2 (better name?) that doesn't
have interrupt window support.

This means that userspace versions that supported KVM_CAP_NMI will not
work with 2.6.29, but I think we can live with that.

If this is acceptable, please send a patch that converts KVM_CAP_NMI to
KVM_CAP_NMI2, and a corresponding patch for userspace. I will fold the
kernel patch into the 2.6.29 submission, and apply both patches to the
master branch.
