+/**
+  Makes a SAL procedure call.
+
+  This is a wrapper function to make a SAL procedure call.
+  No parameter checking is performed on the 8 input parameters,
+  but there are some common rules that the caller should follow
+  when making a SAL call.  Any address passed to SAL as buffers
+  for return parameters must be 8-byte aligned.  Unaligned
+  addresses may cause undefined results.  For those parameters
+  defined as reserved or some fields defined as reserved must be
+  zero filled or the invalid argument return value may be returned
+  or undefined result may occur during the execution of the procedure.
+  This function is only available on IPF.
+
+  @param  Index       The SAL procedure Index number
+  @param  Arg2        The 2nd parameter for SAL procedure calls
+  @param  Arg3        The 3rd parameter for SAL procedure calls
+  @param  Arg4        The 4th parameter for SAL procedure calls
+  @param  Arg5        The 5th parameter for SAL procedure calls
+  @param  Arg6        The 6th parameter for SAL procedure calls
+  @param  Arg7        The 7th parameter for SAL procedure calls
+  @param  Arg8        The 8th parameter for SAL procedure calls
+
+  @return SAL returned registers.
