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:
