Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

arch/powerpc/kernel/setup-common.c:36:10: fatal error: linux/bootmem.h: No such file or directory
 #include <linux/bootmem.h>
          ^~~~~~~~~~~~~~~~~

Caused by commit

  49353a51a758 ("mm: remove include/linux/bootmem.h")

interacting with commit

  d90fe2acd9b2 ("powerpc: Wire up memtest")

from the powerpc tree.

I applied the following patch for today:
