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/vbus/bus-proxy.c: In function 'vbus_driver_ioq_release':
drivers/vbus/bus-proxy.c:192: error: implicit declaration of function 'kfree'
drivers/vbus/bus-proxy.c: In function 'vbus_driver_ioq_alloc':
drivers/vbus/bus-proxy.c:210: error: implicit declaration of function 'kzalloc'
drivers/vbus/bus-proxy.c:210: warning: assignment makes pointer from integer without a cast
drivers/vbus/bus-proxy.c:214: 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 5ff775e4c3d6b0ead7d8784797123a2deed73364 ("ioq: add
driver-side vbus helpers") from the alacrity tree.

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