The following series of patches implement a basic framework
for hypervisor-assisted dump. The very first patch provides 
documentation explaining what this is    :-)   . Yes, its supposed
to be an improvement over kdump.

A list of open issues / todo list is included in the documentation.
It also appears that the not-yet-released firmware versions this was tested 
on are still, ahem, incomplete; this work is also pending.

I have included most of the changes requested. Although, I did find
one or two, fixed in a later patch file rather than the first location
they appeared at.
