For what it's worth, the pi-foundation kernel bcm2710 device tree file 
does:

		arm-pmu {
#ifdef RPI364
			compatible = "arm,armv8-pmuv3", "arm,cortex-a7-pmu";
#else
			compatible = "arm,cortex-a7-pmu";
#endif
			interrupt-parent = <&local_intc>;
			interrupts = <9>;
		};


Which is probably where I was getting the arm,armv8-pmuv3 from in my 
original patch.
