[PATCH 0/3] Split up pv-ops
Paravirt ops is currently only capable of either replacing a lot of Linux
internal code or none at all. The are users that don't need all of the
possibilities pv-ops delivers though.
On KVM for example we're perfectly fine not using the PV MMU, thus not
touching any MMU code. That way we don't have to improve pv-ops to become
fast, we just don't compile the MMU parts in!
