Now that we properly keep track of the CPPR value (since 49bd3647134ea47420067aea8d1401e722bf2aac, "powerpc/pseries: Track previous CPPR values to correctly EOI interrupts") we can pass it to the H_XIRR hcall. This is needed because the Partition Adjunct Option of new versions of pHyp extend the H_XIRR hcall to include the CPPR as an input parameter. Earlier versions not supporting this option just disregard the extra input parameter, so this doesn't cause any problems for existing systems. The Partition Adjunct Option is required for future systems that will support SR-IOV capable devices.
