Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ipc/mqueue.c: In function 'mqueue_get_inode':
ipc/mqueue.c:154:4: error: implicit declaration of function 'vmalloc'
ipc/mqueue.c:154:19: warning: assignment makes pointer from integer without a cast
ipc/mqueue.c: In function 'mqueue_evict_inode':
ipc/mqueue.c:278:3: error: implicit declaration of function 'vfree'

Caused by commit 8a53f9442429 ("ipc/mqueue: update maximums for the
mqueue subsystem").  See Rule 1 in Documentation/SubmitChecklist.

I have added the following patch for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Wed, 5 Oct 2011 19:05:10 +1100
Subject: [PATCH] ipc/mqueue: vlammoc requires vmalloc.h
