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

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (arm
ep93xx_defconfig) failed like this:

mm/slab.c: In function 'is_debug_pagealloc_cache':
mm/slab.c:1608:2: error: implicit declaration of function 'debug_pagealloc_enabled' [-Werror=implicit-function-declaration]

Caused by commit

  0a244aea1a61 ("mm/slab: clean up DEBUG_PAGEALLOC processing code")

CONFIG_DEBUG_PAGEALLOC is not enabled in this build.

Discovered after the linux-next release.
