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/mtd/sm_ftl.c: In function 'sm_create_sysfs_attributes':
drivers/mtd/sm_ftl.c:65: error: implicit declaration of function 'kmalloc'
drivers/mtd/sm_ftl.c:65: warning: initialization makes pointer from integer without a cast
drivers/mtd/sm_ftl.c:71: error: implicit declaration of function 'kzalloc'
drivers/mtd/sm_ftl.c:71: warning: assignment makes pointer from integer without a cast
drivers/mtd/sm_ftl.c:84: warning: assignment makes pointer from integer without a cast
drivers/mtd/sm_ftl.c:88: warning: assignment makes pointer from integer without a cast
drivers/mtd/sm_ftl.c: In function 'sm_delete_sysfs_attributes':
drivers/mtd/sm_ftl.c:107: error: implicit declaration of function 'kfree'
drivers/mtd/sm_ftl.c: In function 'sm_init_zone':
drivers/mtd/sm_ftl.c:757: warning: assignment makes pointer from integer without a cast
drivers/mtd/sm_ftl.c: In function 'sm_add_mtd':
drivers/mtd/sm_ftl.c:1123: warning: assignment makes pointer from integer without a cast
drivers/mtd/sm_ftl.c:1141: warning: assignment makes pointer from integer without a cast
drivers/mtd/sm_ftl.c:1147: warning: assignment makes pointer from integer without a cast
drivers/mtd/sm_ftl.c:1152: warning: assignment makes pointer from integer without a cast
drivers/mtd/sm_ftl.c:1161: 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 7d17c02a01a111f40986859f044c8c4cce8a4aa6 ("mtd: Add new
SmartMedia/xD FTL") from the mtd tree.

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

Subject: [PATCH] mtd: SmartMedia/xD FTL: use of kmalloc/kfree requires the include of slab.h
