--- Comment #38 from Petr Tesařík <ptesarik@xxxxxxxx> ---
I think the upstream thread is confused. ARM says r0p0, r0p1, r0p2, r0p3, r0p4.
In rxpy, the x corresponds to major revision (aka Variant field in MIDR_EL1 aka
"CPU variant" in /proc/cpuinfo), and y corresponds to minor revision or product
revision (aka Revision field in MIDR_EL1 aka "CPU revision" in /proc/cpuinfo).

Commented content of /proc/cpuinfo on a RPi3 system (rpi33.arch) says:

CPU implementer : 0x41
CPU architecture: 8
CPU variant : 0x0 // major revision number 0
CPU part : 0xd03 // Cortex-A53 processor
CPU revision : 4 // product revision number 4

In short, this CPU is r0p4, thus affected by the erratum 843419 according to
ARM official documentation.
