In other words, the lack of a tool-chain in CVS is becoming a drag, not just on those with particular interest in arm, but the project as a whole. For example. after consulting with grehan@ and marcel@, I decided that the best way to finish the PG_NX support on amd64 involved a pmap interface change, which means changing the arm pmap as well as the five that compile out-of-the-box. In summary, I'm not asking for change to come today, but I would like to see signs that there is a plan and progress toward executing that plan. Alan
