So allmodconfig enables CONFIG_BUILD_DOCSRC, which builds the code in Documentation, which is userspace code. In our case we know that won't work because our cross tool chain doesn't have libc, so I've taught kisskb to disable CONFIG_BUILD_DOCSRC for allmodconfig builds. cheers -- Michael Ellerman OzLabs, LTC Prism Kernel Team email: michaele@au.ibm.com stime: ellerman@au1.ibm.com notes: Michael Ellerman/Australia/IBM -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
