    kernel - more cleanup of syscall2()
    
    * Implement an actual SYS___nosys system call.
    
    * Convert one conditional to something that can use CMOV, using
      the new SYS___nosys system call code.
    
    * Get rid of special checks for SYS_syscall and SYS___syscall.
      Instead, provide real vectors for these functions.  This also
      cleans up a few other bits of code in syscall2().
