-// AsmPalCall
-//
-// Makes a PAL procedure call.
-// This is function to make a PAL procedure call. Based on the Index
-// value this API will make static or stacked PAL call. The following table
-// describes the usage of PAL Procedure Index Assignment. Architected procedures
-// may be designated as required or optional. If a PAL procedure is specified
-// as optional, a unique return code of 0xFFFFFFFFFFFFFFFF is returned in the
-// Status field of the PAL_CALL_RETURN structure.
-// This indicates that the procedure is not present in this PAL implementation.
-// It is the caller's responsibility to check for this return code after calling
-// any optional PAL procedure.
-// No parameter checking is performed on the 5 input parameters, but there are
-// some common rules that the caller should follow when making a PAL call. Any
-// address passed to PAL 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. If the PalEntryPoint does not point to a valid
-// PAL entry point then the system behavior is undefined. This function is only
-// available on IPF.
-//
-// On Entry :
-// in0: PAL_PROC entrypoint
-// in1-in4 : PAL_PROC arguments
-//
-// Return Value:
-//
-// As per stacked calling conventions.
