Yes, this is the patch that depends on the "powerpc: Export
__spin_yield" patch that Suresh posted to linuxppc-dev@ozlabs.org and
I acked.

I think the best thing at this stage is probably for Alex to take that
patch through his tree, assuming Michael is OK with that.

The patch is at https://patchwork.ozlabs.org/patch/443703/ or
https://lists.ozlabs.org/pipermail/linuxppc-dev/2015-February/125315.html.

Alex, if you prefer me to post it to kvm-ppc@vger and kvm@vger, let me
know.

Paul.
