yes. Thanks. 

Next steps will be XIVE.  

These patches have not changed at all :

[PATCH v4 04/28] ppc/xive: introduce a XIVE interrupt source model
[PATCH v4 05/28] ppc/xive: add support for the LSI interrupt sources
[PATCH v4 06/28] ppc/xive: introduce the XiveFabric interface
[PATCH v4 07/28] ppc/xive: introduce the XiveRouter model
[PATCH v4 08/28] ppc/xive: introduce the XIVE Event Queues
[PATCH v4 09/28] ppc/xive: add support for the EQ Event State buffers
[PATCH v4 10/28] ppc/xive: introduce the XIVE interrupt thread
[PATCH v4 11/28] ppc/xive: introduce a simplified XIVE presenter
[PATCH v4 12/28] ppc/xive: notify the CPU when the interrupt priority
[PATCH v4 13/28] spapr/xive: introduce a XIVE interrupt controller

These have changed a little :

[PATCH v4 14/28] spapr/xive: use the VCPU id as a VP identifier in
[PATCH v4 15/28] spapr: initialize VSMT before initializing the IRQ
[PATCH v4 16/28] spapr: introdude a new machine IRQ backend for XIVE
[PATCH v4 17/28] spapr: add hcalls support for the XIVE exploitation
[PATCH v4 18/28] spapr: add device tree support for the XIVE
[PATCH v4 19/28] spapr: allocate the interrupt thread context under
[PATCH v4 20/28] spapr: introduce a 'pseries-3.0-xive' QEMU machine

These have changed a lot more :

[PATCH v4 21/28] spapr: add classes for the XIVE models
[PATCH v4 22/28] target/ppc/kvm: add Linux KVM definitions for XIVE
[PATCH v4 23/28] spapr/xive: add common realize routine for KVM
[PATCH v4 24/28] spapr/xive: add KVM support
[PATCH v4 25/28] spapr: fix XICS migration
