[Xen-devel] [RFC PATCH v2 0/2] KVM: x86: Allow Qemu/KVM to use PVH entry point

Changes from v1:

 * Adopted Paolo's suggestion for defining a v2 PVH ABI that includes the
   e820 map instead of using the second module entry to pass the table.

 * Cleaned things up a bit to reduce the number of xen vs non-xen special

Juergen also had a suggestion to split the different hypervisor types
early and use a common set of service functions instead of special casing
xen_guest everywhere.

There are certainly less special cases in this version of the patch, but
if we still think it's important to split things up between common, Xen,
and KVM components, then I would appreciate a suggestion on how best that
can be done. Are we talking about just re-factoring functions in the
existing file? Or do we need to go all the way and pull all the PVH entry
code out of xen directories and find a home for it somewhere else so that
we can use kernels built without CONFIG_XEN to start KVM guests via the
PVH entry point. If the latter, any suggestions for which common files or
directories I can move this stuff to?
