note, that i plan to change the memset code later:
at least rename the functions like

memset_falkor -> memset_zva64_simd
memset_emag -> memset_zva64_nosimd
memset_generic

or similar and then new cpus choose one of these instead
of adding their own (and likely change the default to
memset_zva64_simd for all zva==64 cores), but there might
be code changes as well.

A hearty +1 to this; rth and later I had proposed similar changes in thepast, so I'm happy to see this happen :)


Thanks,
