[PATCH 04/27] Add Book3s fields to vcpu structs

Alexander Graf
2009-10-30T15:47:26Z

We need to store more information than we currently have for vcpus
when running on Book3s.

So let's extend the internal struct definitions.

v3 -> v4:

- use context_id instead of mm_context

v4 -> v5:

- always include pvr in vcpu struct
