Hi all,

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

net/ipv4/route.c: In function 'rt_check_expire':
net/ipv4/route.c:873:4: error: implicit declaration of function 'prefetch' [-Werror=implicit-function-declaration]

Caused by commit 9f28a2fc0bd7 ("ipv4: reintroduce route cache garbage
collector").

Linus, that commit is in the latest pull request you have from Dave ...

I applied the following patch for today:

From: Stephen Rothwell <redacted>
Date: Thu, 22 Dec 2011 17:03:29 +1100
Subject: [PATCH] ipv4: using prefetch requires including prefetch.h
