[PATCH 0 of 2] [RFC] Patches to work with processor-passthru driver (v1).
These two patches provide the neccessary infrastructure changes
for the processor-passthru driver [www.spinics.net/lists/linux-acpi/msg34655.html]
to properly function.
The first one is quite easy - we just modprobe the processor-passthru driver.
The second allows it to work under AMD machines by exposing the PM RDMSR
to dom0. It has been tested with 2.6.32 kernel as well to make sure it does

[PATCH RFC v13 00/20] Introduce PVH domU support
This patch series is a reworking of a series developed by Mukesh
Rathor at Oracle. The entirety of the design and development was done
by him; I have only reworked, reorganized, and simplified things in a
way that I think makes more sense. The vast majority of the credit
for this effort therefore goes to him. This version is labelled v13
because it is based on his most recent series, v11.
