I am trying to port Linux 2.4.6 (uClinux in particular) to the i960.
I had previously worked on such a port where the porting had already
been done for 2.0.  Lots of low level stuff has changed since 2.0, so
I'm having to do lots of the port over again, including the stuff that
had already been done for me.

I find myself needing to know really basic stuff such as what is
required of functions such as (but by no means limited to) copy_thread,
dump_thread, get_wchan, etc.
What they are required to do, what is and needs to be on the stack,
where did current->tss go, etc.
Is there doco on stuff of this level?  I have not found adequate
comments in the source, and searching the web doesn't yield much of use.
