Paolo or Radim,

Please do a pull from my kvm-ppc-fixes-4.16-2 to get one commit that I
would like to have in 4.16.  It fixes a recently-discovered bug whose
main symptom is typically a soft lockup in smp_call_function_many() in
the host.  The bug has been around since 4.8 but it doesn't show up on
POWER8 systems, only on POWER9, which is why we haven't noticed it
before this.

Thanks,
Paul.
