This causes a cascade of new warnings because now functions like
phy_chk() are unused in some configurations.

I'm really not thrilled to even review change from you of this nature
if you aren't going to be careful about attending to details like
that.

Just blindly removing functions and not looking at the context or
other potential side effects is not really acceptable.
