|
|
*
|
|
* This file contains private kernel structures definitions and various
|
|
* other definitions for the Intel Architecture 32 bit (IA-32) processor
|
|
* architecture.
|
|
* The header include/kernel.h contains the public kernel interface
|
|
* definitions, with include/arch/x86/ia32/arch.h supplying the
|
|
* IA-32 specific portions of the public kernel interface.
|
|
*
|
|
* This file is also included by assembly language files which must #define
|
|
* _ASMLANGUAGE before including this header file. Note that kernel
|
|
* assembly source files obtains structure offset values via "absolute symbols"
|
|
* in the offsets.o module.
