Hi Andrew, After merging the akpm-current tree, today's linux-next build (sparc defconfig) failed like this: mm/list_lru.c: In function 'list_lru_del': mm/list_lru.c:141:2: error: implicit declaration of function 'prefetchw' [-Werror=implicit-function-declaration] prefetchw(item->prev); ^ Caused by commit 9b4516980e87 ("mm/list_lru.c: prefetch neighboring list entries before acquiring lock") Missing include of linux/prefetch.h? I have reverted that commit for today. -- Cheers, Stephen Rothwell -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
