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.
The patches mostly work; 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.
