[Patch] Bochs with 4M superpages runs L4Ka

[Farid Hajji]

Hi,

[Kevin: would you please have a closer look at this patch? I'm not
 an x86 expert and this is at best a premature first try at it. -Thanks]

the following patch:

  http://home.kamp.net/home/farid.hajji/l4ka-bochs/

enables 4 MB superpages in bochs. With this hack,
you can boot (among others) L4Ka+root_task without
problems on your favorite workstation ;-) (at least
I hope so!).

Please refer to the file SUPERPAGES in the patched
bochs sources for a quick overview. General instructions
and screen shots can be found on the above URL.

BEWARE: That hack is very alpha and not tested at all!
Don't rely on it too much for now. At least, it won't
destroy your system, since everything is emulated in
software. Bochs may be slow (it is!) but at least it's
more secure than plex86 or vmware and it runs on non-
intel boxes too.

If you find any bugs (e.g. bochs panics()), please try to
track them down and fix the sources as far as possible.
It is easier than it sounds because bochs sources are
very clear and because you can insert printf()s everywhere.
Try this with a real processor!

Thanks,

-Farid.
