I don't know exactly which paths of the page-walk API are walked
by the nommu stuff. 

The changes in mm/mmap.c and mm/mlock.c are really necessary,
even if you don't plan to apply this patch.

I implemented some comments from Kai, Doug, Gerd and you. I hope
the current implementation is now more valuable and correct.

If I need to implement the complete API also for nommu, then I
could also implement it for the vmalloc() space, because this is
nearly the same, what do you think?

This time I could only check compilation, because gcc 2.95.2 has problems
compiling fs/readdir.c and I had to back it out, leaving an unusable kernel
behind.
