The mecanincal changes in C code are pretty simple,
but you really need a running machine to do them because
you need to change-compile-change-compile-change-compile (etc.)
It took me about 1 day to do the i386 specific things..
Having doen that is should take someone with a running alpha
abut a half day to do the alpha version (now that I've
done the 386) and someone with a clue
about alpha assembler needs to make the same changes to the
machine code. (it was probably about 10 lines of assembler changes).
The bigest part is the re-arranging of the u-area and changing the
code to follow that change.

I REALLY want to have alpha (and hopefully other) ready to do at the same
time.
but at the same time, I'm 'carrying this' because as long as I'm not
committed I have a daily "merge" job. And it's getting bigger
as people change low level code in way s that may not be compatible
with what I need.
I would be happy if I could commit it in 2 weeks. I'd like some help from
the other architecture people though.
I've done 1.85 MB of patches and the machine dependednt parts are probably
about 15K of that.
