Yes, please. The email address is fine but the name doesn't have to have that funky "-oc" thing.

I don't mind you using steppings to differentiate the two as long as this is not going to change all of a sudden and that differentiation is unambiguous.
If not, you will have to use name strings as you don't have any other choice.
Whatever you do, pls define a new X86_BUG_ flag, set it only on Nano and then test it in the PMU init code.
Thx.
