/**

|
* @brief Kernel structure member offset definition file
|
|
*
|
|
* This module is responsible for the generation of the absolute symbols whose
|
|
* value represents the member offsets for various IA-32 structures.
|
|
*
|
|
* All of the absolute symbols defined by this module will be present in the
|
|
* final kernel ELF image (due to the linker's reference to the _OffsetAbsSyms
|
|
* symbol).
|
|
*
|
|
* INTERNAL
|
|
* It is NOT necessary to define the offset for every member of a structure.
|
|
* Typically, only those members that are accessed by assembly language routines
|
|
* are defined; however, it doesn't hurt to define all fields for the sake of
|
|
* completeness.
