  24. // To add a system service simply add the name of the service to the below
  25. // table. If the system service has in memory arguments, then immediately
  26. // follow the name of the service with a comma and following that the number
  27. // of bytes of in memory arguments, e.g. CreateObject,40.
  28. //
  29. // N.B. Note that the gp corresponding to KiServiceTable must be placed
  30. // just before KiServiceTable.
  31. // Given that code must be at least 16-byte aligned, bits 1-3 are used
  32. // used to encode number of arguments up to a value of 7. The following
  33. // forumal is used numargs > 8 ? (((numargs - 8 + 1)/2) + 8) : numargs
