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

Hi Tejun,

After merging the slabh tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/dma/timb_dma.c: In function 'td_alloc_init_desc':
drivers/dma/timb_dma.c:381: error: implicit declaration of function 'kzalloc'
drivers/dma/timb_dma.c:381: warning: assignment makes pointer from integer without a cast
drivers/dma/timb_dma.c:389: warning: assignment makes pointer from integer without a cast
drivers/dma/timb_dma.c:410: error: implicit declaration of function 'kfree'
drivers/dma/timb_dma.c: In function 'td_probe':
drivers/dma/timb_dma.c:710: warning: assignment makes pointer from integer without a cast

Caused by commit d103d3b3e8512312b5254950035366d4422a479a ("percpu: don't
implicitly include slab.h from percpu.h") from the slabh tree interacting
with commit de5d4453c5b224eefd02b6a141ed411a76d458af ("dma: Add
timb-dma") from the async_tx tree.

I applied the following merge fixup patch which should be applied to the
async_tx tree (see Documentation/SubmitChecklist Rule #1 :-)).

Subject: [PATCH] async_tx: use of kzalloc/kfree requires the include of slab.h
