2  * Adapted from Linux v2.6.36 kernel: arch/powerpc/kernel/asm-offsets.c
3  *
4  * This program is used to generate definitions needed by
5  * assembly language modules.
6  *
7  * We use the technique used in the OSF Mach kernel code:
8  * generate asm statements containing #defines,
9  * compile this file to assembler, and then extract the
10  * #defines from the assembly-language output.
