+ 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.
+
