[RFC PATCH 0/3] spapr: nested-hv support for TCG |

Here's a little thing I've been hacking on. I was pretty amazed I
could even get it working, let alone being so small and not too
horrible to look at. A few people thought it would be useful for
prototyping and hacking and running kvm tests, etc. So, thoughts
on the overall idea and code structure?
There's possibly a few layering violations there with me short-cutting
and not calling vhc method for checking cpu in nested at least, and a
bit of cleanup and few loose ends, but hopefully nothing fundamentally
terrible.
It works and boots an L2 into a distro with unmodified Linux kernels
running in the L1 and L2.
Thanks,
Nick
