[PATCH 0/2] KVM: PPC: Book3S HV: XIVE: Improve guest entries and exits

The XIVE interrupt controller on P10 can automatically save and
restore the state of the interrupt registers under the internal NVP
structure representing the VCPU. This saves a costly store/load in
guest entries and exits.

Thanks,

C.
