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.
