Yah, and after discussing this w/ Bill Sommerfeld, he set me straight
and I now have my head wrapped around the non-recursive PT mapping used
by the ARM pmap (sigh, I have been working on this code too long; my
eyes are starting to glaze over).

That still doesn't change my puzzlement with what's going on with the
mdpage change...
