Hi all,

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

iterators").

I added the following patch for today:

Hi all,

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

mm/prio_tree.c: In function 'vma_prio_tree_next':
mm/prio_tree.c:178: error: implicit declaration of function 'prefetch'

Caused by commit e66eed651fd1 ("list: remove prefetching from regular list
iterators").

I added this patch  for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Fri, 20 May 2011 16:19:57 +1000
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 thids build error on sparc32:

mm/prio_tree.c: In function 'vma_prio_tree_next':
mm/prio_tree.c:178: error: implicit declaration of function 'prefetch'
