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

Hi all,

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

drivers/video/udlfb.c: In function 'dlfb_compress_hline':
drivers/video/udlfb.c:421: error: implicit declaration of function 'prefetch_range'

Presumably caused by commit e66eed651fd1 ("list: remove prefetching from
regular list iterators").  We need to include preempt.h explictly, now.

I have included this patch for today:

Subject: [PATCH] udlfb: include prefetch.h explicitly

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

fixes this build error on powerpc:

drivers/video/udlfb.c: In function 'dlfb_compress_hline':
drivers/video/udlfb.c:421: error: implicit declaration of function 'prefetch_range'
