Hi @lw if it’s tedious to check all these changes at once, I can delete this PR and create several trivial PRs out of this one, easer to check. What do you think?

Hi,
Is it still something you want to merge here?
As stated before, this approach most likely will be hard to implement on H100s, and probably it would be more efficient to pack the weights in a different scheme

Hello @danthe3rd,
This commit is only about making it easier to add new activation functions. I may try to implement optimization for H100 later, not in this MR. No other commits were planned to push in this MR.
