Because otherwise these objects won't be built and their exports had been conditional on that as well: #if defined(CONFIG_CPU_HAS_NO_MULDIV64) /* * Simpler 68k and ColdFire parts also need a few other gcc functions. */ extern long long __divsi3(long long, long long); extern long long __modsi3(long long, long long); extern long long __mulsi3(long long, long long); extern long long __udivsi3(long long, long long); extern long long __umodsi3(long long, long long); EXPORT_SYMBOL(__divsi3); EXPORT_SYMBOL(__modsi3); EXPORT_SYMBOL(__mulsi3); EXPORT_SYMBOL(__udivsi3); EXPORT_SYMBOL(__umodsi3); #endif is what we have in mainline m68k_ksyms.c. Neither allmodconfig, nor any of defconfigs have it. And on a coldfire build they are built and exported as expected: $ grep si3 ../build/coldfire/System.map 002be860 T __divsi3 002be890 T __modsi3 002be8b8 T __mulsi3 002be8dc T __udivsi3 002be90c T __umodsi3 003ed960 R __ksymtab___divsi3 003edc80 R __ksymtab___modsi3 003edca8 R __ksymtab___mulsi3 003edff8 R __ksymtab___udivsi3 003ee000 R __ksymtab___umodsi3 003f7ba4 r __kcrctab___divsi3 003f7d34 r __kcrctab___modsi3 003f7d48 r __kcrctab___mulsi3 003f7ef0 r __kcrctab___udivsi3 003f7ef4 r __kcrctab___umodsi3 004144fe r __kstrtab___divsi3 00414507 r __kstrtab___modsi3 00414510 r __kstrtab___mulsi3 00414519 r __kstrtab___udivsi3 00414523 r __kstrtab___umodsi3 -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
