Paravirt ops is currently only capable of either replacing a lot of Linux

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!
This patchset splits pv-ops into several smaller config options split by
feature category and then converts the KVM pv-ops code to use only the
bits that are required, lowering overhead.
Alexander Graf (3):
Split paravirt ops by functionality
Only export selected pv-ops feature structs
Split the KVM pv-ops support by feature
The whole thing looks good to me. Let's wait for Jeremy to ack though.

Do not meddle in the internals of kernels, for they are subtle and quick to
