This is pretty much a complete rewrite based on the existing i386 code. The patches have been circulating for a couple years and have been looked at by plenty of people, but I'm not putting anybody on the hook as having reviewed this in any formal sense except myself. After this has gotten wider testing from the user community, ARM_NEW_PMAP will become the default and various dregs of the old pmap code will be removed.
