[PATCH 00/23] Add KVM support for PPC64 (970) hosts

[Alexander Graf <agraf@suse.de>]

KVM for PowerPC only supports embedded cores at the moment.

While it makes sense to virtualize on small machines, it's even more fun
to do so on big boxes. So I figured we need KVM for PowerPC64 as well.

This patchset implements KVM support for PPC64 hosts and guest support
for PPC64 and G3/G4.

To really make use of this, you will also need a modified version of qemu
that can deal with KVM on desktop cores. I will send out patches for those
later, but want to get feedback on the kernel side first.

In the meanwhile, use the qemu version from
http://www.powerkvm.org/powerkvm.git which already includes all required
patches to run PPC32 and PPC64 guests.
