* @brief Private kernel definitions (IA-32)
*
* 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/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.
