0 // 8 is the actual number of argument registers//++//// Copyright (c) 1989 Microsoft Corporation//// Module Name://// systable.s//// Abstract://// This module implements the system service dispatch table.//// Author://// David N. Cutler (davec) 29-Apr-1989//// Environment://// Kernel mode only.//// Revision History:////--
//// To add a system service simply add the name of the service to the below// table. If the system service has in memory arguments, then immediately// follow the name of the serice with a comma and following that the number// of bytes of in memory arguments, e.g. CreateObject,40.//// N.B. Note that the gp corresponding to KiServiceTable must be placed// just before KiServiceTable.// Given that code must be at least 16-byte aligned, bits 1-3 are used// used to encode number of arguments up to a value of 7. The following// forumal is used numargs > 8 ? (((numargs - 8 + 1)/2) + 8) : numargs//
