   * @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/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.
