Hi Sam, Today's linux-next build (powerpc ppc64_defconfig) failed like this: WARNING: modpost: Found 11 section mismatch(es). To see full details build your kernel with: 'make CONFIG_DEBUG_SECTION_MISMATCH=y' .tmp_kallsyms1.S:1:23: error: asm/types.h: No such file or directory I have dropped the kbuild tree for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
