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.
