Many thanks for the review feedback we have received so far,
and many thanks to Andrew for reviewing our common code memory
management changes. I do greatly appreciate that :-).

All important parts have been reviewed, all review feedback has been
integrated in the code. Therefore we would like to ask for inclusion of
our work into kvm.git.

Changes from Version 1:
- include feedback from Randy Dunlap on the documentation
- include feedback from Jeremy Fitzhardinge, the prototype for dup_mm
has moved to include/linux/sched.h
- rebase to current kvm.git hash g361be34. Thank you Avi for pulling
in the fix we need, and for moving KVM_MAX_VCPUS to include/arch :-).

Changes from Version 2:
- include feedback from Rusty Russell on the virtio patch
- include fix for race s390_enable_sie() versus ptrace spotted by Dave
Hansen: we now do task_lock() to protect mm_users from update while
we're growing the page table. Good catch, Dave :-).
- rebase to current kvm.git hash g680615e

Todo list:
- I've created a patch for Christoph Helwig's feedback about symbolic
names for machine_flags. This change is independent of the kvm port, and
I will submit it for review to Martin.
