This series contains several cleanups to the handling of the
ibm,client-architecture-support firmware call used for boot time
feature negotiation between the guest OS and the firmware &
hypervisor.
Mostly it's just internal polish, but one significant user visible
change is that we no longer generate an extra CAS reboot to switch
between XICS and XIVE interrupt modes (by far the most common cause of
CAS reboots in practice).
David Gibson (4):
spapr: Don't trigger a CAS reboot for XICS/XIVE mode changeover
spapr: Improve handling of fdt buffer size
spapr: Fold h_cas_compose_response() into
h_client_architecture_support()
spapr: Simplify ovec diff
