Paolo or Radim,
Please do a pull from my kvm-ppc-next-4.16-2 tag to get some PPC KVM
fixes that I would like to have go into 4.16. Most of them are quite
self-contained; there are two that are larger (and arguably don't
quite count as bug fixes), but I have checked them carefully and
convinced myself that they have a low risk of causing regressions, and
they do address issues that have been found in testing, so I put them
in.
With things like this I would normally put them in my kvm-ppc-fixes
branch and base it on current upstream. However, as far as I can see
the kvm next branch hasn't been merged upstream yet. Therefore I made
this series a continuation of my kvm-ppc-next branch.
When do you expect that kvm/next will get merged upstream?
Thanks,
Paul.

KVM: PPC: Book3S: Add MMIO emulation for VMX instructions (2018-02-09 16:51:51 +1100)
----------------------------------------------------------------
Second PPC KVM update for 4.16
Seven fixes that are either trivial or that address bugs that people
are actually hitting. The main ones are:
- Drop spinlocks before reading guest memory
- Fix a bug causing corruption of VCPU state in PR KVM with preemption
enabled
- Make HPT resizing work on POWER9
- Add MMIO emulation for vector loads and stores, because guests now
use these instructions in memcpy and similar routines.
