Subject: linux-next: build failure after merge of the akpm tree

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:155:4: error: implicit declaration of function 'vmalloc' [-Werror=implicit-function-declaration]
ipc/mqueue.c:155:19: warning: assignment makes pointer from integer without a cast [enabled by default]
ipc/mqueue.c: In function 'mqueue_evict_inode':
ipc/mqueue.c:268:3: error: implicit declaration of function 'vfree' [-Werror=implicit-function-declaration]

Caused by commit 5d644d9d3d8f ("ipc/mqueue: update maximums for the
mqueue subsystem").  See Rule 1 from Documentation/SubmitChecklist.

I have added the following patch for today:
