Could you check the rest of these over to see if they truly don't need
to be implemented for no-mmu?
you're right we want mremap, my fault


Yes, I do think so, both sys_mremap and sys_munmap are implemented in
mm/nommu.c. How do think of this, Bernd?

There's a mremap in nommu.c, but it doesn't do a lot that is useful. With some further mm changes in our tree, it's little more than a fancy way of saying munmap, and uClibc does not use it, so there's no compelling need to have it in userspace.
