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! This

Hi folks, With this series, the bulk of the work of pvops64 is done. Here, I integrate most of the paravirt.c and paravirt.h files, making them applicable to both architectures. CONFIG_PARAVIRT is _not_ present yet. Basically, this code is missing page table integration (patches currently being worked on by Jeremy). Enjoy
