The patch series adds support for power10 PMU hardware. Patches 1..3 are the clean up patches which refactors the way how PMU SPR's are stored in core-book3s and in KVM book3s, as well as update data type for PMU cache_events. Patches 12 and 13 adds base support for perf extended register capability in powerpc. Support for extended regs in power10 is covered in patches 14,15 Other patches includes main changes to support for power10 PMU.
