* PVR masks/values from arch/powerpc/kernel/cputable.c (Linux kernel)
* PVR masks/values from Linux kernel:
* - arch/powerpc/kernel/cputable.c (kernel <= 6.0)
* - arch/powerpc/kernel/cpu_specs_book3s_64.h (kernel >= 6.1)
*
* In the kernel, there is a POWER8E identifier. In
* https://wiki.raptorcs.com/wiki/POWER8E it says it is
* actually DD2.1, while other POWER8 should be DD2.0.
* The last assumption does not seem to be correct according
* to https://openbenchmarking.org/s/POWER8NVL, which shows a
* POWER8NVL where kernel says it is DD1.0. We implement this
* to show only the uarch, not the revision, since it seems a bit
* redundant?
*
* This list may be incorrect, incomplete or overly simplified,
* specially in the case of 32 bit entries
