Subject: linux-next: build failure after merge of the final tree

Hi all,

After merging the final tree, today's linux-next build (sparc32 defconfig)
failed like this:

mm/slab.c: In function '__cache_alloc':
mm/slab.c:3493: error: implicit declaration of function 'prefetchw'

Applied this patch:

Subject: [PATCH] mm: include prefetch.h

Commit e66eed651fd1 ("list: remove prefetching from regular list
iterators") removed the include of prefetch.h from list.h, so include
it explicitly.

Fixes this build error on sparc32:

mm/slab.c: In function '__cache_alloc':
mm/slab.c:3493: error: implicit declaration of function 'prefetchw'
