  23   Makes a SAL procedure call.
  24
  25   This is a wrapper function to make a SAL procedure call.
  26   No parameter checking is performed on the 8 input parameters,
  27   but there are some common rules that the caller should follow
  28   when making a SAL call.  Any address passed to SAL as buffers
  29   for return parameters must be 8-byte aligned.  Unaligned
  30   addresses may cause undefined results.  For those parameters
  31   defined as reserved or some fields defined as reserved must be
  32   zero filled or the invalid argument return value may be returned
  33   or undefined result may occur during the execution of the procedure.
  34   This function is only available on IPF.
  35
  36   @param  Index       The SAL procedure Index number
  37   @param  Arg2        The 2nd parameter for SAL procedure calls
  38   @param  Arg3        The 3rd parameter for SAL procedure calls
  39   @param  Arg4        The 4th parameter for SAL procedure calls
  40   @param  Arg5        The 5th parameter for SAL procedure calls
  41   @param  Arg6        The 6th parameter for SAL procedure calls
  42   @param  Arg7        The 7th parameter for SAL procedure calls
  43   @param  Arg8        The 8th parameter for SAL procedure calls
  44
  45   @return SAL returned registers.
