[PATCH 00/30] KVM: PPC: e500mc support

[Alexander Graf <agraf@suse.de>]

This is Scott's e500mc RFC patch set rebased, berobbed of its pt_regs
parts and fixed for bisectability. On top of them, I addressed all the
comments that I had on the code and that came up in his code as FIXMEs.

I verified that this patch set works just fine on e500mc and doesn't
break e500v2, so I would say it's good to go as it is, unless someone
has strong objections to how things are done. Everything hereafter
I would prefer to do based on a working upstream version rather than
a downstream fork, as that way exposure is a lot higher.
