Alexander Graf - Oct. 30, 2009, 3:47 p.m.
We need to store more information than we currently have for vcpus
when running on Book3s.

So let's extend the internal struct definitions.

Signed-off-by: Alexander Graf <agraf@suse.de>

---

v3 -> v4:

  - use context_id instead of mm_context

v4 -> v5:

  - always include pvr in vcpu struct
