Gets rid of code that creates absolute symbols for data structures that are no longer referenced by external tools, as well as the macro that was used to generate them. The code that creates absolute symbols for context monitoring-related symbols is retained, but is now directly tied to the CONTEXT_MONITORING configuration option upon which those symbols depend.

DESCRIPTION
|
|
This module is responsible for the generation of the absolute symbols whose
|
|
value represents the member offsets for various IA-32 nanokernel structures.
|
|
|
|
All of the absolute symbols defined by this module will be present in the
|
|
final microkernel or nanokernel 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.
