Subject: Remove needfree, desfree, lotsfree #defines

Remove needfree, desfree, lotsfree #defines

This patch reverts 77ab5dd.  This is now possible because upstream has
refactored the ARC in such a way that these values are only used in a
few key places.  Those places have subsequently been updated to use
the Linux equivalent Linux functionality.
