Hi Rusty, After merging the modules tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: arch/powerpc/platforms/powernv/opal-elog.c:85:28: error: macro "__ATTR_RO" passed 2 arguments, but takes just 1 __ATTR_RO(id, elog_id_show); ^ arch/powerpc/platforms/powernv/opal-elog.c:85:2: error: '__ATTR_RO' undeclared here (not in a function) __ATTR_RO(id, elog_id_show); ^ arch/powerpc/platforms/powernv/opal-elog.c:87:32: error: macro "__ATTR_RO" passed 2 arguments, but takes just 1 __ATTR_RO(type, elog_type_show); ^ And it went down hill from there ... Caused by commit ba987e9b8ab1 ("arch/powerpc/platforms/powernv/opal-elog.c: fix world-writable sysfs files"). I have used the modules tree from next-20140725 again for today. There is still the error in arch/powerpc/platforms/powernv/opal-dump.c ... -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
