This is v5 of the patches posted at:
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=37250
This series has been tested using mambo for p8 (hash) and p9 (radix),
and also on Power8 host.
In v5, the patch for KVM has been re-worked and is now [6/10], instead
of [2/10]. This now works properly on a Power8 machine. More details in
the patch. All other patches are unchanged from v4.
