Mh. Should I just drop the const and put a description referring to an
advised name? The driver with the kpss-gcc hardcode the name to
acpu_l2_aux that's why I thought it was a correct conversion using a
const but I assume this is another problem of not making a correct 1:1
conversion and adding fixes on pure conversion.
Think I should drop it and put a description to it. (and then later fix
it when I will push the other series with all the tweaks)

What do you think?
