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:

drivers/infiniband/hw/mlx4/cm.c: In function 'id_map_alloc':
drivers/infiniband/hw/mlx4/cm.c:228:36: error: 'MAX_ID_MASK' undeclared (first use in this function)

Caused by commit d7a4e9b679e9 ("IB/mlx4: Add CM paravirtualization") from
the infiniband tree interacting with commit "idr: rename MAX_LEVEL to
MAX_IDR_LEVEL" from the akpm tree.

I have added the following merge fix patch for today:
