Paolo,

Please do a pull to get three commits which fix problems relating to
interrupts on POWER9.  The problems which are fixed here can cause
interrupts to get missed, leading to guest hangs and stalls.  I would
like these to go into 4.13.

Thanks,
Paul.

Sure, would you also like me to include "[PATCH really v2] KVM: PPC:
Book3S: Fix race and leak in kvm_vm_ioctl_create_spapr_tce()"?

Yes, that would be good, thanks.  I don't know of any exploit, but
this kind of thing can sometimes be exploitable in non-obvious ways.

Thanks,
