To test I first run a different command line tool that shows family/model using sde -tnt The model 0x96 is among 3 supported supported by Linux According to wikichip there is only 1 Intel e-core missing from cpuinfo after this PR: Skymont is only available on hybrid cpus so it does not have an cpu family/model of it's own. |

In this PR the darkmont is moved from Knights to Low-Power cores
and gracemont model 0xBE is documented as Alderlake N instead of Twin Lake, which may have an additional model.
