I've tested these patches on a Raspberry Pi 3B running a 32-bit upstream (4.17-rc5-git) kernel and they work.
[ 0.472906] hw perfevents: enabled with armv8_cortex_a53 PMU driver, 7 counters available
I only needed to add this to the devicetree
arm-pmu { compatible = "arm,cortex-a53-pmu"; interrupt-parent = <&local_intc>; interrupts = <9 IRQ_TYPE_LEVEL_HIGH>; };
