i wouldn't say it's "plain wrong".  merely outdated.  there were a bunch of 
syscalls that existed at the initial merge (because the Blackfin arch was based 
on m68k iirc) that we dropped because it was useless cruft.  there are still 
holes in the Blackfin syscall table for them, but they go to ENOSYS as you've 
seen.  there are probably a bunch more than just old_mmap.
