[Geekos-devel] user mode works again

[David H. <da...@cs...>]

User mode works again.  Right now a user context's virtual memory
structures and associated memory pages are not tracked properly, so that's
the next thing I will work on.

We need to start thinking about how to present OS services to
user applications.  At the moment I'm leaning towards a traditional
monolithic kernel with POSIX (at least a subset) as the API.
However, I'm open to suggestions.
