re my last post about pmap notes on
the file is in the FAQ directory not the doc directory.

(btw.. I've been reading through the amiga and NetBSD mmu
stuff and there seems to be some slight changes of interface.
One thing not mentioned in the pmap-notes file is the
MACHINE_NONCONTIG which seems to play a similar role as the
MACHINE_POGED variable in the notes.  From the sources it
looks like the x86 port is using MACHINE_NONCONTIG to deal
with the 0-640k and then 1meg+, where-as the amiga port doesnt
define this and assumes all memory is in just one chunk.  The
differences between the two interfaces are a bit larger than
just changing the define though, some new routines in
arch/amiga/amiga/pmap.c need be written).
