Log message:
Many changes, since my account on cvs.tartarus.org has been dead for a few days:

* GENERIC kernel is now built with options DIAGNOSTIC and options DEBUG.
This necessitated a few source fixes.
* Exception handlers now do vaguely useful things if called from non-USR
modes.  We include the arm32 debugger, but I don't know if it works.
* bootconfig has changed incompatibly.  This should make future changes
easier.
* I believe the kernel is now actually being loaded properly.  BBBB seems
to be zeroing the bss in the right place, and we call ld with -s to stop
it dumping the symbol table on top of the data segment.  I think in future
BBBB should understand symbol tables enough to spot such bogosities.
* We now have a real (if less-than-minimal) pmap implementation.  It seems
to work, and I understand it so far.
* cpu_startup() caught up with the rest of the world.
* Pool pages are now accessed through physical memory.
* arcvideo console driver tries to preserve what's on the screen, but
something around there's not working.
