The main reason for removing the NexGen support was that the latter had effectively been broken for G-d knows how many years. As a person somehow involved into embedded development, I simply could not resist to trim a few dozen bytes of dead binary code off vmlinux. Besides, the change is trivially revertable (just checked that), and in case that somebody owns a NexGen box and complains, that can be addressed in a matter of minutes. Dmitri > > Pavel >
