>Description:
lib/libkvm/kvm_sun3x.c defines two file-local macros - _kvm_kvas_size() and _kvm_nkptes() which are not referenced anywhere in the file.

They seems appear to be leftovers from an earlier version of the address translation code.

A little patch attached to remove dead macros.
>How-To-Repeat:
