+\r
+ Makes a PAL procedure call.\r
+ This is a wrapper function to make a PAL procedure call. Based on the Index value,\r
+ this API will make static or stacked PAL call. Architected procedures may be designated\r
+ as required or optional. If a PAL procedure is specified as optional, a unique return\r
+ code of 0xFFFFFFFFFFFFFFFF is returned in the Status field of the PAL_CALL_RETURN structure.\r
+ This indicates that the procedure is not present in this PAL implementation. It is the\r
+ caller¡¯s responsibility to check for this return code after calling any optional PAL\r
+ procedure. No parameter checking is performed on the 4 input parameters, but there are\r
+ some common rules that the caller should follow when making a PAL call. Any address\r
+ passed to PAL as buffers for return parameters must be 8-byte aligned. Unaligned addresses\r
+ may cause undefined results. For those parameters defined as reserved or some fields\r
+ defined as reserved must be zero filled or the invalid argument return value may be\r
+ returned or undefined result may occur during the execution of the procedure.\r
+ This function is only available on IPF.\r
+\r
+ @param Index - The PAL procedure Index number.\r
+ @param Arg2 - The 2nd parameter for PAL procedure calls.\r
+ @param Arg3 - The 3rd parameter for PAL procedure calls.\r
+ @param Arg4 - The 4th parameter for PAL procedure calls.\r
+\r
+ @return structure returned from the PAL Call procedure, including the status and return value.\r
