"icswx" is not a thing anymore, after 6ff4d3e96652 ("powerpc: Remove old unused icswx based coprocessor support"). I guess NX is reusing some things from it, but it would be good to get rid of the cruft and re-name this file and and relevant names. NX already uses this file, so I guesss that can happen after this series. Thanks, Nick
