[PATCH] uclinux: fix mmap() of directory for nommu case
I was playing with blackfin when i hit a neat bug ... doing an open() on a directory and then passing that fd to mmap() would cause the kernel to hang after poking into the code a bit more, i found that mm/nommu.c:validate_mmap_request() checks the length and if it is 0, just returns the address ... this is in stark contrast to mmu's mm/mmap.c:do_mmap_pgoff() where it returns -EINVAL for 0 length requests ... i then noticed that some other parts of the logic is out of date between the two funcs, so perhaps that's the easy fix ?
