    kernel - Fix token ordering in sysctl_kern_proc_args(), sysctl_kern_proc_cwd()
    
    * We have to PHOLD() first, then get p->p_token, not the other way around.
      Use pfind() instead of pfindn().
    
    * Extract and ref the the ncdir from p->p_fd before calling cache_fullpath()
      on it to ensure stability.
