linux-next: build failure after merge of the final tree (akpm tree related)

Hi all,

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

fs/direct-io.c: In function '__blockdev_direct_IO':
fs/direct-io.c:1327:2: error: implicit declaration of function 'prefetch'

Caused by commit 30ddb4d48213 ("dio: optimize cache misses in the
submission path").

I have added this patch for today:

From: Stephen Rothwell <redacted>
Date: Wed, 28 Sep 2011 19:58:28 +1000
Subject: [PATCH] dio: using prefetch requires including prefetch.h
