Nice find. Minor nit on naming. The 32-bit code mostly uses the numeric names, eg. 603, 603e, 604 etc. Can we stick with that, rather than using "G2"? Wikipedia says G2 == 603e. But looking at your patch you're not changing all the 603e cores, so I guess it's not that clear cut? If using "G2" makes the most sense then it would be nice to update Documentation/arch/powerpc/cpu_families.rst to mention it (not asking you to do it necessarily, more a note for us). cheers
