Remove the now unused ksys_chdir. FWIW, my problem with that is that you are making it first-class primitive. And I don't see any valid use for it - existing one is really "we have a userland process that would be making syscalls if we only could have it done right; the only reason we can't is that the infrastructure to build the binary would be hell to maintain in the tree". It's *NOT* "kernel code that has a valid reason to get the syscall functionality".
