/**
* @file
* @brief ARM 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 ARM kernel 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.
