Paolo,
Please do a pull from my kvm-ppc-next branch to get PPC KVM updates
for v4.9. The highlights are:
* Reduced latency for interrupts from PCI pass-through devices, from
Suresh Warrier and me.
* Halt-polling implementation from Suraj Jitindar Singh.
* 64-bit VCPU statistics, also from Suraj.
* Various other minor fixes and improvements.
This includes the patches on my kvm-ppc-infrastructure branch, which
is also available for Michael Ellerman to pull into the powerpc tree.
Unfortunately I put in Paolo's patch to move hmi.c, not realizing that
Ben had already sent it to Linus. However, since the patch is
identical, git merges it without complaint, so I have left it in,
because otherwise I would have to rebase my kvm-ppc-next branch, which
I try very hard not to do. Paolo, if you prefer me to rebase my
kvm-ppc-{next,infrastructure} branches to remove the patch, let me
know.
Paul.
