Hi Andrew, After merging the akpm-current tree, today's linux-next build (powerpc allyesconfig) failed like this:
lib/test_user_copy.c: In function 'test_user_copy_init': lib/test_user_copy.c:111:2: error: implicit declaration of function 'csum_partial_copy_from_user' [-Werror=implicit-function-declaration] csum_partial_copy_from_user(usermem, kmem, PAGE_SIZE, 0, &err); ^ Caused by commit 0b6e2917b6fc ("lib/test_user_copy.c: check user checksum functions") It looks like PowerPC 64 bit has an implementation of csum_and_copy_from_user() that does not use csum_partial_copy_from_user() and so this latter does not exist. You need to check for _HAVE_ARCH_COPY_AND_CSUM_FROM_USER. I have reverted that commit for today. -- Cheers, Stephen Rothwell s...@canb.auug.org.au -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
