22/**
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.
