| * |
| * 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. |
