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