xtensa: re-wire umount syscall to sys_oldumount
commit 2651cc6974d47fc43bef1cd8cd26966e4f5ba306 upstream. Userspace actually passes single parameter (path name) to the umount syscall, so new umount just fails. Fix it by requesting old umount syscall implementation and re-wiring umount to it. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
