Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

/*
|
|
* we need this inline - forking from kernel space will result
|
|
* in NO COPY ON WRITE (!!!), until an execve is executed. This
|
|
* is no problem, but for the stack. This is handled by not letting
|
|
* main() use the stack at all after fork(). Thus, no function
|
|
* calls - which means inline code for fork too, as otherwise we
|
|
* would use the stack upon exit from 'fork()'.
|
|
*
|
|
* Actually only pause and fork are needed inline, so that there
|
|
* won't be any messing with the stack from main(), but we define
|
|
* some others too.
